2013-08 / 04 Catalogue LM1 - 008 UK Page 48 Edition Accessories spring-loaded multi-disc brake - clutch coupling - planetary gear - bevel spur gear Spring- loaded multi- disc brake The standstill holding brake holds the drive in position under load with depressurized pneumatic motor. It opens pneumatically via a valve (4bar) and closes by means of spring force when the pneumatic pressure is switched off. Clutch coupling A pneumatic clutch is for example used for emergency drive, wich not run permanently. In the unpressurized state, the clutch is open by spring force. By pneumatic pressure (which can be accessed at the measuring terminals of the pneumatic motor), the frictional clutch and puts into effect the emergency drive. Once the pneumatic motor that delivers its torque is due to the pressure rotors, clutch switches on, initiation of the test, the applied pressure. This says that in an emergency, the clutch and accepts the pneumatic motor, switched on the frictional clutch, the drive. Planetary gear Commercially available planetary gear units may be installed downstream of the pneumatic motor. The dimensions of these coaxial gear units are significantly smaller than those of the pneumatic motor, and the gears have very tight gear shifting. 1-shift i= 3,08 - 7,25 2-shift i= 10,04 - 50,30 3-shift i= 60,00 - 320,00 Bevel spur gear The output of bevel spur gears is 90° offset vis-a-vis the pneumatic motor. The output shaft is either on the right or the left side, or o both sides. Thanks to its rectangular output, the pneumatic motor stands rectangular to the drive axis, with coaxially reduces the overall length. Because of their weight, the bevel spur gears must be fixed to the same frame as the pneumatic motor. i= 4,4 - 730
