4 ES -Compact - the economically viable protection for machines Function If the set limit torque is exceeded, the clutch disengages. The torque drops immediately. mounted registers the disengagement movement and switches off the drive. The signal can also be used for further control functions. fter the malfunction has been rectified, the ES -Compact ratchetting clutches and the ES -Compact synchronous clutches automatically re-engage (for a detailed description of the re-engagement behaviour, see page ). ES - Compact overload clutches separate the input and the output side completely and remain in this state until they are intentionally re-engaged by hand or via a suitable device. detailed description of the overload clutches starts on page 26.

44 Technical Explanations Readable Torque djustment The ES -Compact overload clutch offers easily readable torque adjustment on the adjusting nut (for sizes 01 to 3). This readability makes adjusting the torque far more simple, and also allows easy checks on the set release value on the installed clutch. The limit torque can be finely adjusted and accurately read due to the adjusting nut with the fine thread and the easily-readable graduation scale. The positive-locking (or frictionally-locking) safeguard on the adjusting nut protects against self-turning, inadvertent adjustment of the set limit torque. The integral blocking protection prevents the cup springs from becoming spring-bound B D C Fig. 1: ES -Compact ratchetting and synchronous clutch Torque djustment djustment takes place by turning the adjusting nut () (sizes 03 to 3) or the set screws (6) (sizes 4 and ). The installed cup springs (9) are operated in the negative range of the characteristic curve (Fig. 3). stronger pre-tension produces a decrease in spring force. Turning the adjusting nut () (sizes 03 to 3) or the set screws (6) (sizes 4 and ) clockwise therefore produces a decrease in spring force. Turning it anti-clockwise produces an increase in torque (facing direction towards the adjusting nut () Figs. 1 and 2). If no other torque adjustment is requested customer-side, the ES -Compact ratchetting, synchronous and overload clutch is generally set and marked (calibrated) manufacturer-side to c. 70 % of the respective maximum torque. The respective torque adjustment or the adjustable torque range are visible on the Type tag. control spring application in the operating range can be carried out via the dimension a. ES -Compact ratchetting and synchronous clutch (sizes 01-3): Dimension a is the distance between the adjusting nut facing side () to the pressure plate facing side (3) (Fig. ). ES -Compact overload clutch (sizes 01-3): Dimension a is the distance between the adjusting nut facing side () to the hub edge (1) (Fig. 6). For the corresponding data, please see the Installation and Operational Instructions. 3 1 a 1 a Marking Fig. Fig Fig. 2: ES -Compact overload clutch Move to operational range Force F Graph of spring characteristic curve Operational range Spring path S Fig. 3 (The diagram only serves as an example) 2 Torque M G [Nm] Difference Graduation 4 grad. lines lines Fig. 4 (The diagram only serves as an example) Important Guideline! Depending on the drive and the drive constellation, torque peaks (e.g. via start-up torque impacts on asynchronous motors) can occur which lie substantially above the system (motor) operating torque. This behaviour is to be taken into account customer-side when dimensioning or adjusting the clutch. ES -NC sizes 03 and 02 must be adjusted according to the djustment Diagram (please order if necessary) if no adjustment or calibration was made manufacturer-side. ES -NC size 03 (Fig. 7): Unscrew both set screws (8) from the adjusting nut (). Grease the thread surfaces on the adjusting nut () and the hub (1). Set the adjusting nut () to the required dimension a (acc. djustment Diagram) using a hook wrench. Paint both set screws (8) with Loctite 243, screw them into the adjusting nut () and tighten them. ES -NC size 02 (Fig. 8 and Fig. 4): Loosen the locking screw (2). Grease the contact surfaces on the adjusting nut (), the locking ring (4) and the hub (1). Set the adjusting nut () by hand to the contact on the cup spring (9). Continue to turn until the four notches on the circumference of the adjusting nut () and the notches in the locking ring (4) align. Turn the adjusting nut () further using a face wrench to the number of graduation lines which equal the required torque (Fig. 4, number of graduation lines in the djustment Diagram). The 4 notches on the circumference of the adjusting nut () and on the locking ring (4) must be in the same position. Paint both set screws (8) with Loctite 243 and screw them into the adjusting nut (). Fig. 7 a 8 1 Fig

45 Technical Explanations Torque djustment s 01 to 3 (Figs. 1, 2 and 6): Convert the required torque (acc. formula below) in percent of the max. adjustment value: Required torque Max. torque adjustment (see Table Technical Data) x 100 = djustment % Loosen the locking screw (2) in the adjusting nut (). Turn the adjusting nut () clockwise or anti-clockwise according to the engraved adjustment scale (Figs. 1 and 2) using a hook wrench or a face wrench, until the required torque is set. The required torque results from: the locking ring (4) marking (D) overlap and the percent value (C) on the adjusting nut () (ratchetting and synchronous clutch, Fig. 1), or the hub (1) marking overlap and the percent value on the adjusting nut () (overload clutch, Figs. 2 and 6). Paint the locking screw (2) with Loctite 243 and screw it into the adjusting nut (); the 4 notches () in the adjusting nut () and the notches (B) in the locking ring (4) must be in the same position (Fig. 1). Correct slightly if necessary. Re-engagement of the ES -Compact overload clutch Re-engagement ES -Compact overload clutch takes place simply by placing axial pressure onto the thrust washer (3). Slight twisting between the clutch input and output sides may be necessary. s 01 to 3: Depending on the application possibilities, the ease of entrance at the installation point etc., re-engagement can take place in different ways: Manually, e.g. using a plastic hammer or installation levers supported on the adjusting nut () (e.g. two screwdrivers placed opposite each other). With an engagement device. The engagement device can be automated using pneumatic or hydraulic cylinders. s 4 and : Re-engagement takes place using 3 hexagon head screws (Fig. 10; provided by the user: M8 for sizes 4 and ): The screws are screwed in evenly in the adjusting nut () by placing axial pressure onto the thrust washer (3). Please Observe! fter successful re-engagement, the three hexagon head screws must be removed immediately, as otherwise the clutch is blocked. Example: ES -Compact size 3, Type (M G max. = 30 Nm): Torque pre-adjustment = 7 % of M G max. = 24 Nm. The adjustment should be increased from 24 Nm to 280 Nm. Define the torque adjustment in percent of M G max. using the formula below.: Fig. 9 Warning! 9 a s 4 and (Figs. 9 and 10): 7 6 Fig a M8 3 x 120 djustment only takes place by turning the set screws (6) and not by turning the adjusting nut (): Loosen all hexagon nuts (7). x 100 = 80 % Turn the adjusting nut () according to the facing-side scale (Fig. 1) anti-clockwise from 7 % to 80 % on the adjustment scale using a face wrench. Tighten all set screws (6) evenly using an llen wrench to the required dimension a. ES -Compact ratchetting and synchronous clutch, size 4: find dimension a in the djustment Table glued to the clutch (Fig. 9). ES -Compact overload clutch, sizes 4-: find dimension a in the djustment Table (10) glued to the adjusting nut () (Fig. 10). Counter the set screws (6) again using hexagon nuts (7). fter clutch disassembly (e.g. due to cup spring or cup spring layering replacement), the clutch must be re-set! 6 7 Warning! Re-engagement may only take place during standstill or at a low differential speed (< 10 rpm). For a more detailed explanation on re-engagement, please see the respective Installation and Operational Instructions. Permitted bearing load The output element is centred on the deep groove ball bearing (tolerance /h) and screwed to the pressure flange (3). If the resulting radial force from the output element lies roughly in the ball bearing centre and is below the maximum permitted radial load according to Table 1, an additional bearing for the output element is unnecessary.

54 Installation Examples Installation Examples ES -Compact short hub The drive elements of the ES -Compact short hub are centred on the deep groove ball bearing and are screwed together with the pressure flange. If the resulting radial force from the drive element is anywhere near the centre of the ball bearing, an additional bearing for the drive element is unnecessary. Fig. 1 Please Observe: The screw quality and the tightening torque for the fixing screws of the drive element are to be selected so that the set limit torque can be safely transmitted using frictional locking. ES -Compact long protruding hub The ES -Compact long protruding hub is recommended for very wide drive elements or for elements with very small diameters. On a small diameter, the drive element is screwed together via a customer-side intermediate flange with the clutch pressure flange. Ball bearings, needle bearings or plain bearings are suitable as bearings for the drive element, depending on the installation situation and the installation space. Fig. 2 ES -Compact with flexible shaft coupling The ES -Compact with a backlash-free, torsionally flexible and vibration-damping shaft coupling for the connection of two shafts. The coupling compensates for axial, radial and angular misalignments. In comparison to the ES -Compact with steel bellows coupling, this product is torsionally flexible to a small extent in the circumferential direction. In the installation example on the right, the ES -Compact lastic is mounted backlash-free between the rotor and a ball screw spindle. The torque is transmitted backlash-free up to the point of disengagement and drops immediately on overload. The contactless (sensor) emits a signal to switch off the drive. Fig. 3 ES -Compact with steel bellows coupling The ES -Compact with a torsionally rigid flexible steel bellows coupling for the connection of two shafts. The coupling compensates for axial, radial and angular misalignments. It is torsionally rigid in the circumferential direction. 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 mounted between the rotor and a ball screw spindle. The torque is transmitted backlash-free up to the point of disengagement and drops immediately on overload. The contactless (sensor) emits a signal to switch off the drive. Fig. 4 4
