2 Gear Proucts ROSS+MORSE ross+morse offer a comprehensive range of stanar stock gears which, couple with the capability to supply on short lea times custom esigne gears, provies the esign engineer with a wie spectrum of solutions from which to select open gear rives. Stanar Stock Gears The range of stanar stock gears is etaile in the following catalogue pages, incluing recommenations for gear selection, can be summarise as follows: evel an Mitre Gears Straight ut evel an Mitre Gears manufacture to the Gleason system in meium carbon steels enable simple right angle rives with reuction ratios up to :. Two series of gears are offere, the first the original T.. ross range to imperial imensions from P to P pitch, the secon a much improve metric range of gears from Mo. to Mo. pitch. ll gears can be inuction or flame harene for longer life uner aruous conitions. Spur Gears new range of P.. spur gears all manufacture in meium carbon steel, provie selection from Mo. through to 6 Mo. pitch with gears from teeth to 7 teeth. ll gears have face with equal to ten times Mo. number to provie sensible power transmission capability. To supplement the steel gears is a select range of cast iron wheels covering pitch range 2 Mo. to Mo. with to tooth size. Straight Racks vailable in stanar lengths of 0.,.0 an 2.0 metres is a range of P.. straight cut racks with pitch range Mo. to 6 Mo. These are esigne to combine with the stanar spur gears to provie low cost conversion of rotary to linear motion. Special ustom Mae Gear Proucts Moification of stanar gears by reworking the bore an faces, an aing heat treatment often provies the most economical gear solution; but for those applications where stanar gears cannot be use, special gears an racks can be manufacture within the following limits. Mitre an evel Gears Straight cut gears to the Gleason System up to 0mm iameter, can be provie in a variety of materials. Spur Gears In iametrical, circular or moule pitches with tooling available most pitch sizes in both /2 an pressure angle for gears up to 7mm iameter. Helical Gears With helix angles up to an pitch iameter up to 7mm. Straight Racks Racks of Moule or iametrical (P) pitches can be supplie up to 2 Metre length an pitch up to Mo or.p. Internal Gears an Splines s up to 6mm can be machine to a epth of 0mm either stanar spur gear or internal splines. Splines an Serrations Involute, flat root, or fillet root splines an serrations can be cut on machine shafts or customer blanks. Special Gearboxes ustom esigne gear systems can be supplie to suit iniviual rive requirements, using spur gears, helical gears, or inverte tooth chain. Shaft centres to /2 metres an power ratings to 00KW have been provie. We welcome the opportunity to quote for your requirements.

3 evel an Mitre Gears ROSS+MORSE evel an Mitre Gears are use to transmit power between shafts intersecting at, on low spee, high torque applications where pitch line velocity oes not excee m/s. ll ross+morse gears are cut to the Gleason System to provie equal strength between pinion an gear. Interchangeability evel gears of ientical pitch an teeth but from ifferent rive ratio gearsets are not interchangeable. ll bevel gears are generate on the pitch cone raius which varies with the ratio of gears within a given iametral pitch. Installation ll mitre an bevel gears evelop en thrust which must be counteracte by bearings of aequate capacity. ccurate an rigi mounting of both gear an pinion provie quiet operation an long life. earing spacing an shaft stiffness shoul be selecte to keep shaft eflection below.0mm. Lubrication Grease lubrication can be aequate for low spee applications but oil splash lubrication is always preferable. The oil level shoul cover the face of the lower gear, an sufficient capacity shoul be available to keep oil temperature below. Efficiency When correctly aligne, a bevel gearset with oil lubrication can operate with transmission efficiency up to 9 per cent.

9 Spur Gear Selection ROSS+MORSE For a require centre istance an gear ratio a suitable pair of spur gears can be selecte use an assesse by the following proceure. Select numbers of teeth in gears an moule (pitch). Z2 Gear Ratio i = (Teeth riven gear) Z (Teeth riven gear) Shaft centre istance in mm = sum gear teeth x pitch = (Z + Z2) P From this initial selection each gear can be assesse for strength an wear using the following formulae. The least of the four calculate powers is the capacity of the gear set. The capacity require is etermine by multiplying actual power by a service factor relative to river an riven equipment, refer page c2. If calculate power is below require capacity increase pitch or face with of gears, ajust teeth sizes accoringly, an reassess rive.
