44 Technical Explanations Reaable Torque justment The ES -Compact overloa clutch offers easily reaable torque ajustment on the ajusting nut (for s 0 to 3). This reaability makes ajusting the torque far more simple, an also allows easy checks on the set release value on the installe clutch. - The limit torque can be finely ajuste an accurately rea ue to the ajusting nut with the fine threa an the easily-reaable grauation scale. - The positive-locking (or frictionally-locking) safeguar on the ajusting nut protects against self-turning, inavertent ajustment of the set limit torque. The integral blocking protection prevents the cup springs from becoming spring-boun B D C Fig. : ES -Compact ratchetting an synchronous clutch Torque justment justment takes place by turning the ajusting nut () (s 03 to 3) or the set screws (6) (s 4 an ). The installe cup springs (9) are operate in the negative range of the characteristic curve (Fig. 3). stronger pre-tension prouces a ropping in spring force. Turning the ajusting nut () (s 03 to 3) or the set screws (6) (s 4 an ) clockwise therefore prouces a ecrease in spring force. Turning it anti-clockwise prouces an increase in torque (facing irection towars the ajusting nut () Figs. an 2). If no other torque ajustment is requeste customer-sie, the ES -Compact ratchetting, synchronous an overloa clutch is generally set an marke (calibrate) manufacturer-sie to approx. 70 % of the respective maximum torque. The respective torque ajustment or the ajustable torque range are visible on the type tag. control spring operation in the operating range can be carrie out via the imension a. ES -Compact ratchetting an synchronous clutch (s 0 3): Dimension a is the istance between the ajusting nut facingsie () to the thrust washer facing-sie (3) (Fig. ). ES -Compact overloa clutch (s 0 3): Dimension a is the istance between the ajusting nut facingsie () to the hub ege () (Fig. 6).

This behaviour is to be taken into account customersie when imensioning or ajusting the clutch. ES -NC s 03 an 02 must be ajuste accoring to the justment Diagram (please orer if necessary) if no ajustment or calibration was mae manufacturer-sie. ES -NC 03 (Fig. 7): Unscrew both set screws (8) from the ajusting nut (). Grease the threa surfaces on the ajusting nut () an the hub (). Set the ajusting nut () to the require imension a (acc. justment Diagram) using a hook wrench. Paint both set screws (8) with Loctite 243, screw them into the ajusting nut () an tighten them. ES -NC 02 (Fig. 8 an Fig. 4): Loosen the locking screw (2). Grease the threa an contact surfaces on the ajusting nut (), the locking ring (4) an the hub (). Set the ajusting nut () by han up to contact on the cup spring (9). Continue to turn until the four notches on the circumference of the ajusting nut () an the notches in the locking ring (4) align. Turn the ajusting nut () further using a face wrench to the number of grauation lines which equal the require torque (Fig. 4, number of grauation lines in the justment Diagram). The 4 notches on the circumference of the ajusting nut () an on the locking ring (4) must be in the same position. Paint the locking screw (2) with Loctite 243 an screw it into the ajusting nut ().

Require torque ajustment Max. torque ajustment (see Table Technical Data) 9 a 7 6 x 00 = justment in % Loosen the locking screw (2) in the ajusting nut (). Turn the ajusting nut () clockwise or anti-clockwise accoring to the engrave ajustment scale (Figs. an 2) using a hook wrench or a face wrench, until the require torque is set. The require torque results from: the locking ring (4) marking (D) overlap an the percent value (C) on the ajusting nut () (ratchetting an synchronous clutch, Fig. ), or the hub () marking overlap an the percent value on the ajusting nut () (overloa clutch, Figs. 2 an 6). Paint the locking screw (2) with Loctite 243 an screw it into the ajusting nut (); the 4 notches () in the ajusting nut () an the notches (B) in the locking ring (4) must be in the same position (Fig. ). Correct slightly if necessary. Example: ES -Compact 3, Type (M G max. = 30 Nm): Torque pre-ajustment = 70 % of M G max. = 24 Nm. The ajustment shoul be increase from 24 Nm to 280 Nm. Define the torque ajustment in percent of M G max. using the formula below: 280 x 00 = 80 % 30 Turn the ajusting nut () accoring to the facing-sie scale (Fig. ) anti-clockwise from 70 % to 80 % on the ajustment scale using a face wrench. Fig. 9 Fig a M8 3 x 20 s 4 an (Figs. 9 an 0): The torque is change exclusively via the set screws (6) an not via the ajusting nut ().

Counter the set screws (6) again using hexagon nuts (7). fter e-installing the clutch (e.g. ue to cup spring replacement or changes to the cup spring layering), the clutch must be re-ajuste. 6 7 Re-engagement of the ES -Compact overloa clutch ES -Compact overloa clutch re-engagement is carrie out by applying axial pressure onto the thrust washer (3). It may be necessary to turn between the clutch input an output sies slightly. Re-engagement must only take place when the evice is not running or at low ifferential spee (< 0 rpm). For a more etaile explanation on re-engagement, please see the respective Installation an Operational Instructions. Depening on the equipment available, the accessibility of the installation point etc., re-engagement can be carrie out in the following ways: s 0 to 3: Manually, e.g. using a plastic hammer or installation levers supporte on the ajusting nut () (e.g. 2 screwrivers place opposite each other). By using an engagement mechanism. The engagement proceure can also be automate using pneumatic or hyraulic cyliners. s 4 an : By evenly screwing 3 hexagon hea screws M8 (provie by the customer) into the ajusting nut () (Fig. 0).

54 Installation Examples ES -Compact short hub The rive elements of the ES -Compact short hub are centre on the eep groove ball bearing an are screwe together with the pressure flange. If the resulting raial force from the rive element is anywhere near the centre of the ball bearing, an aitional bearing for the rive element is unnecessary. Fig. The screw quality an the tightening torque for the fixing screws of the rive element are to be selecte so that the set limit torque can be safely transmitte using frictional locking. ES -Compact long protruing hub The ES -Compact long protruing hub is recommene for very wie rive elements or for elements with very small iameters. On a small iameter, the rive element is screwe together via a customer-sie intermeiate flange with the clutch pressure flange. Ball bearings, neele bearings or plain bearings are suitable as bearings for the rive element, epening on the installation situation an the installation space. Fig. 2 ES -Compact with flexible shaft coupling The ES -Compact with a backlash-free, torsionally flexible an vibration-amping shaft coupling for the connection of two shafts. The coupling compensates for axial, raial an angular shaft misalignments. In comparison to the ES -Compact with steel bellows coupling, this prouct is torsionally flexible to a small extent in the circumferential irection. In the installation example on the right, the ES -Compact lastic is mounte backlash-free between the rotor an a ball screw spinle. The torque is transmitte backlash-free up to the point of isengagement an rops immeiately on overloa. The contactless (sensor) emits a signal to switch off the rive. Fig. 3 ES -Compact with steel bellows coupling The ES -Compact with a torsionally rigi flexible steel bellows coupling for the connection of two shafts. The coupling compensates for axial, raial an angular shaft misalignments. It is torsionally rigi in the circumferential irection. In comparison with the ES -Compact with ROB -D coupling, the ES -Compact with steel bellows coupling has a lower mass moment of inertia. In the installation example on the right, the ES -Compact with steel bellows coupling is mounte between the rotor an a ball screw spinle. The torque is transmitte backlash-free up to the point of isengagement an rops immeiately on overloa. The contactless (sensor) emits a signal to switch off the rive. Fig. 4 4
