2 Introduction ELATECH manufactures polyurethane belts for linear motion, conveying and power transmission applications. The combination of a polyurethane body reinforced with special steel or aramid tension members, makes the belt to fulfil the most severe requirements in all industrial applications. The unique manufacturing processes, realized with the newest generation technologies, the modern and efficient test and control equipment, allow delivering superior products with the highest flexible service. ELATECH offers the widest range of tooth profile to enable the design engineer the use of the best drive for every application. In addition to that, for special applications, ELATECH studies and delivers innovative and unique solutions to even the most complex requirements. Product range ELATECH M - open end ELATECH M belts are produced in standard roll length of m and delivered to any desired length. The excellent precision and dimensional stability, the high abrasion resistance make them ideal in all linear motion applications. ELATECH V - jointed They are jointed belts obtained from open-end belts. The special manufacturing process, allows obtaining any desired length. Due to the high flexibility and to the unique precision in positioning offered, ELATECH V belts are ideal for all conveying applications where synchronisation is needed. ELA-flex SD ELA-flex SD Synchro Drive belts are manufactured with truly endless steel tension cords. Having no splice or welding, they have no weak cross section and are therefore ideal for power transmission and high load conveying applications. They are available in a wide range of profiles and pitches and in any length tooth by tooth from mm to 2 mm. Endless tension cord Polyurethane 2

4 Introduction The timing belts manufactured by ELATECH have been designed to comply to every need of the design engineer in linear motion, power transmission and in conveying applications where precise synchronisation is needed. ELATECH timing belts are manufactured with the body in thermoplastic polyurethane with excellent wear resistance and with high tensile strength steel cords. A special polyamide fabric on the tooth (on request) reduces the coefficient of friction, improves the tooth engagement and reduces noise. Standard belt Belt with Polyamide fabric on teeth PAZ Tension Cords In order to maximize the application of ELATECH timing belts, construction with special cords is available on request: Standard Cord HPL high performance cords: the cord cross section is increased compared with standard. This results in a lower belt elongation and more precise positioning accuracy. HFE high Flexibility cords: the cord cross section is spread on a higher number of single filaments. This results in a lower bending stress and therefore in a higher resistance at reverse bending of the cords. They allow using pulleys and idlers up to 3% smaller in diameter compared to standard. INOX stainless steel cords are suitable for application in aggressive environments. They have lower tensile strength than standard cords. Aramid: increases belt flexibility and decreases belt weight. It is to be noted that steel cords offer the best technical performances and dimensional stability of the belts. For application with special cords ask our engineering department. Product certification - ELATECH belts are certified to be according RoHS 2/95/EC - On request, it is possible to deliver belts according to: 94/9/CE ATEX II2G-22D Antistatic according to ISO 9563 (with special fabric) Colour ELATECH timing belts are produced as standard in white colour. On demand it is possible to deliver belts in different colours. Mechanical properties: HFE Cord HPL Cord Excellent dimensional stability High abrasion resistance Low pretension and shaft load Maintenance free High linear and angular positioning precision High efficiency Chemical properties: High resistance to: 4 Hydrolysis Ozone UVA Ageing Oils, greases and fats Gasoline Good resistance to acids Working temperatures range - C +8 C (peaks up to 1 C) For very low temperature special compound material is available on request.

72 ELATECH ECOLIFT belts ELATECH flat belts superior construction makes them the best solution in a wide range of lifting applications. Compared to steel cable they offer proven reliability, highly compact drives, maintenance-free operation and excellent dynamic properties. ELATECH flat belts are produced with a polyurethane body ensuring very high wear resistance. Steel tension cords of opposite construction (Z and S) are laid out in pairs to maximize dynamic properties. They provide excellent operational performance with low noise and vibrations and long lifetime. Compact size and maintenance-free operation allow: low inertia, space savings and therefore lower manufacturing cost solutions lower power consumption in operation and therefore reduced running costs In order to optimize the application in load and flexibility, ELATECH flat belts are produced in a range of different thicknesses and steel cord diameters. Pulley diameter depends on the type of belt and on the design load required by the application. Our catalogue reports minimum diameters for use with the maximum allowable load. For an accurate pulley diameter calculation under different load conditions please contact out technical department. The recommended pulley geometry is cylindrical with side flanges. Proper design of belt ends is recommended to ensure application safety. Some possible design solutions for belt end clamping are shown here as examples. 72

79 Drive calculation GUIDELINES Pulleys It is recommended to use pulleys with the maximum diameter allowed by the application in order to maximise the number of teeth in mesh and increase the belt peripheral speed. For applications where high positioning precision is required, it might be useful to use zero backlash pulleys. In order to guarantee a reliable drive, it is recommended to use superior quality pulleys Machine structure For a trouble free drive, it is recommended that the structure of application of the timing belt drive, is as rigid as possible. That will guarantee high work repeatability. Clamping plates In case of use of clamping plates, they must have the belt profile, be rigid and guarantee a uniform clamping force on all the surface. It is recommended to have a minimum of 8 teeth in clamp to guarantee catalogue performances. In case of belts with HPL cords, the recommended number of teeth in clamp is 12.

However if there are unknown peaks or shock loads or swings in the peripheral force unknown at design time, which therefore can not be included in the calculation parameters, a suitable safety factor should be considered by the designer. Steady load c 1 = 1 Peak or fluctuating loads: Light c 1 = 1,4 Medium c 1 = 1,7 Heavy c 1 = 2, 81

82 Calculation Linear drives are correctly dimensioned when the total peripheral force, necessary for the requested work, satisfies the 3 technical parameters of the selected belt: - tooth shear strength - allowable - flexibility The necessary data for the calculation are: the mass to be moved, the transmission cycle, the drive layout with the related forces, the resisting force of friction. Friction force is generally determined by the linear bearing manufacturer. In case of conveying applications, it is resulting from the weight of the conveyed goods and the coefficient of friction between slider bed and belt surface. In case of accumulating conveyors the friction between the conveyed goods and the backside of the belt must be considered additionally. Select belts and pulleys For initial belt profile and pitch selection, use the graphs available in the related catalogue section. For the choice of the pulleys it is recommended to use pulleys with the largest possible diameter. That will reduce the belt width and optimise drive performances.

Note: = 12 for belts ELATECH M = 6 for belts ELATECH V Determine installation pretension F TV Linear motion drives are correctly tensioned when in the slack side a minimum tension is guaranteed in all working conditions and for every value of F Tmax (acceleration, deceleration). It is recommended a pretension of: F TV FU F TV,5 F U Verify of allowable The maximum load on the belt will appear when both the pretension F Tv and the working load F U will act at the same time: F Tmax = F TV + F U 1 z e The maximum allowable of the belt F tzul (see technical tables of corresponding selected belt) must be greater than the maximum working load: > F Tmax for linear drives with ELATECH M belts for conveying applications with ELATECH V belts Calculate the necessary total pheripheral force F U and torque M F = m a + m g + m g μ U F = F + F + F U ab b H R Verify flexibiliy The diameter of the chosen pulleys, must be greater or equal to the minimum recommended diameter for the specific belt profile chosen (see technical data). The load (m g sinα) must be considered only in vertical or inclined drives when a mass is lifted against gravity. FU dw M = 82

83 Calculate shaft load The shaft load under static conditions is: F Wsta = 2 F TV The shaft load under dynamic conditions is: F Wdyn = 2 F TV + F U Calculate necessary static elongation Installation tension generates a belt elongation Δl between the shafts (for linear drives) or the clamping plates (for "Omega" drives). Being F U the resulting force on the slide, the positioning deviation generated by belt elongation is: F Δ U S = C The positioning accuracy is also depending on other parameters and therefore for an accurate calculation, please consult our technical department. Installation and drive pretensioning: ELATECH M and V Linear drive Omega drive FTV L Δl = 2 C R spez FTV L Δl = C spez R In order to pretension a drive is possible to use one of the following methods: 1) Measuring elongation ELATECH timing belts with steel cords have a constant elongation to the maximum allowable load. Therefore the correct pretension can be set by measuring the belt elongation with a gauge and using as a reference the graph load/elongation of the selected belt type. This is a simple method but requires a good accessibility of the drive. If the resulting elongation is not acceptable for the application, it is possible to reduce it by increasing the belt width. Determine the positioning accuracy The stiffness coefficient of linear drives depends on the lenght of slack and tight side in the drive. Every position of the system has its own stiffness coefficient calculated with the formula: 2) Using span deflection The pretension is checked by applying a force in the centre of the span length and measuring the span deflection 3) Measuring frequency The tension of the belt is calculated from the natural frequency of vibration of the belt span which is measured by means of a special belt tension meter. This is the most accurate and easiest method. A suitable belt tension meter is availabile a ailabile from ELATECH L C R C = spez R= 1 + L1 L2 L L L 2 For C spez value see technical data of selected belt type. Stiffness coefficient will be minimum when slack and tight side will have the same length during the working cycle. C min 4 C = L R spez With L R equal to the belt length free to elongate (excluding contact length on timing pulleys). 83

The graphs have been designed considering the maximum speed () generally used in the applications for every belt profile and pitch and have included a safety factor increasing with the acceleration. Therefore, depending on the specific values of the application, it might be needed to change the belt width upon calculation. a (m/sec 2 ) T2,5 ELATECH M and V ,,,, m (kg) T5 a (m/sec 2 ) m (kg) 85

121 Safety factors Belt selection is made according to a constant working load. In case of peak loads and vibrations a safety factor c 1 must be considered. Transmission with steady load c 1 = 1, Transmission with peak or fluctuating loads: Light c 1 = 1,4 Medium c 1 = 1,7 Heavy c 1 = 2, For speed up driver factor c 2 must be considered: Calculate teeth in mesh β ze = z k 36 with β [ ] = wrap angle Determine belt width ( z z ) t g β = 2 arccos 2 π A P c b = z z P k e spez k M c b = z z M k e spez i = from,66 to 1 c 2 = 1,1 i = from,4 to,66 c 2 = 1,2 i <,4 c 2 = 1,3 The resulting total safety factor is: c = c 1 c 2 Verifiy allowable The allowable of the belt must be highter than the total corrected peripheral force. M > c F U with FU = d W Drive calculation The necessary data for drive calculation are: Power to be transmitted P [kw] Driver n 1 [min -1 ] Motor starting torque M ab [Nm] Required center distance A [mm] Maximum driver pulley diameter d w1 [mm] Calculate shaft load F F Wsta Wsta = 2 F = 2 F Tv Tv cos β ( i = 1) for ELA-flex SD Select type of belt For the initial drive selection, use the selection graphs illustrated in the relative ELA-flex SD cataloge section. For initial pulley choice, it is recommended to use the driver pulley with maximum diameter allowable in the application. Calculate drive ratio Calculate belt lenght Belt lenght for drive with ratio i # 1 L R and more precisely: L n i = n driver driven Belt lenght for drive with ratio i = 1 L = 2 A + π d R t 2 ( z + z ) g k w + 2A + 1 4A β t 2A sin + zg + z 2 2 = 2 A + z t 2 ( z z ) t g π k β ( z z ) R = k g k Determine installation tension A drive is correctly tensioned when the belt slack side is tensioned in all working conditions. It is also important to use the minimum necessary tension to minimize shaft loads. Belt tension is dependent also on belt length LR and its number of teeth ZR. According to belt number of teeth, following tension is suggested: 2 shafts drive Z R < 75 F TV = 1/3 F U 75 < ZR < 1 F TV = 1/2 F U ZR > 1 F TV = 2/3 F U More than 2 shafts drive F TV > F U In order to ensure the correct drive installation ten- sion, it is recommended to use the special belt tension meter availaba ailable le from ELATECH. 121

125 Polyurethane belts for conveying applications

126 Polyurethane belts for conveying applications The unique chemical and mechanical characteristics of ELATECH belts together with the possibility of a wide variety of backings in different materials make ELATECH belts ideal for all conveying applications where synchronization is required. The engineer designer has unlimited possibilities to make unique designs. Minimum pulley diameter The recommanded minimum pulley diameter can be calculated using the pulley multiplier shown for each type of backing Minimum pulley diameter = backing thickness x pulley multiplier C D The diameters obtained are valid for application with speed up to 1m/s and temperature of C. When smaller pulley diameter are needed please consult with Elatech technical department. Drive with reverse bending ELATECH polyurethane timing belts are suitable for drives with reverse bending. Tension should be adjusted, depending on backing hardeness. Temperature Hot items may be conveyed when a correct backing is selected. In such a case, ensure that the belt toothed structure does not over come 8 C. Polyamide fabric backings The special polyamide fabric backings allow a reduction of the friction coefficient and when applied on teeth, decrease noise in high speed drives. They are very useful in applications with sliding surfaces or product accumulation. Coefficent of friction Polyurethane on steel μ =,7 Polyammide on steel μ =,35 PAZ: PAR: Polyamide backing on tooth side Reduces coefficient of friction and allows a smother tooth engagement.

130 ELATECH EMF - Mechanical Fastening System (patent pending) ELATECH EMF - Mechanical Fastening System allows in many conveying applications cost savings associated with being able to design equipment around the installation principle of EMF. Features EMF has no exposed metal parts, therefore no metal contact is made with pulleys, so it runs very quiet. Since there are no exposed metal parts, EMF will not damage conveyed products like competing metal based mechanical fastening alternatives. EMF maintains the same minimum pulley requirements as the belt and can operate with back bend idlers. It is excellent for belt applications with special backings such as Linatex, Supergrip, PVC, Fishbone, etc. EMF fits snug, which eliminates gaps otherwise seen in competing designs. It is suitable for belts with profiles for quick installation, saving time and money. EMF installs in seconds, making it the fastest timing belt installation for product conveyance. There is no need for time-consuming field welding. It is simple to install and requires no cumbersome or expensive field welding equipment. It can be custom designed according to the application strength needed. EMF can reach the same strength as the traditional welding. It is available on all pitches, making it a "must have" for all of your customer's conveying applications. 13

131 ELATECH polyurethane belts with profiles It is possible to attach profiles on all ELATECH and ELA-flex SD polyurethane belts for conveying, handling and positioning applications. The cleats are produced in the same material of the belts in order to guarantee the maximum strenght. The belts with profiles allow a syncronised translation of the products at very high speeds and low noise. A very wide range of profiles is available. If the required profile is not shown in the following pages, please contact with our technical office. Arc of contact It is to be noted that the belt's arc of contact may be restricted by the jointed profile. It is therefore recommended to select profiles with the minimum allowable thickness "U". Pitch It is recommended to chose the pitch of the profile corresponding to the belt profile or multiple. This allows to minimize the effects of the belt overall length tolerance on profile spacing. Position Profiles position may be over the tooth or not over the tooth. Belt Flexibility is maximised when the profiles are applied over the tooth. Fig. 1 Fig. 2 Tolerances The tolerance of position of the profiles is +/-,5 mm. If required it is possible to reduce the tolerance down to +/-,2 mm with an extra machining. During the welding process a bead of polyurethane of about,5-1 mm develops at the meeting point between the profile and the belt. Should it be necessary for the application, it is possible to remove it with a mechanical machining. Belt type T5 T T AT5 AT AT XL L H XH HTD5M HTD8M HTD14M STD5M STD8M Ordering Profile thickness U (mm) Recommended minimum pulley number of teeth z Minimum number of teeth when the profile is welded on tooth gap (fig. 2) Minimum number of teeth when the profile is welded on tooth (fig. 1) PROFILES When ordering it is necessary to indicate: type of belt (width, profile, pitch, length), the belt length in number of teeth, the belt and profile drawing with the number and the pitch of the requested profiles Special execution On demand it is possible to produce special belts with special machining both on the teeth and on the back of the belt. 131

132 ELATECH EFT - Mechanical Profile System EFT is ELATECH's mechanical profile application system specially designed for attaching cleats that cannot be welded onto polyurethane timing belts. It is offered in zinc-coated or stainless steel teeth with either our embedded tooth or total tooth design. The total tooth design replaces the entire tooth of the belt and has two securing threaded holes. The embedded tooth design eliminates metal-to-metal contact, making this a more quiet solution. Total tooth design Embedded tooth design Features A self-centering effect on profile positioning, which makes it more precise than welded profiles. Can handle much higher loads than welded profiles, making it a strong solution. It is the precise solution eliminating any welded profile positioning tolerances. The profile positioning tolerance for EFT mirrors the ELATECH timing belt tooth pitch tolerance. It is flexible, allowing customers to reposition cleats for regularly schedule application changes. It is economical because customers can replace worn profiles without replacing the entire belt. It is available in any of the following pitches: AT, ATK, AT, H, XH. It is versatile, allowing customers to attach cleats made of steel, stainless steel, plastic, urethane, wood, or virtually any other material. ELATECH EFT typical applications: AT AT 132
