摘要

#CMT# #/CMT# The operating device (2) has a worm gear (12) and a worm gear pair (8), which has a worm (10) arranged on a worm shaft (6). A brake disk (30) is displaced axially opposite to a worm shaft and is arranged on the worm shaft with its rotating end. The brake disk blocks reference list by an oppositely lying non rotating friction body (34) and pressed during actuation of a rocker arm (38) at the brake disk. #CMT#USE : #/CMT# Operating device for valve or armature. #CMT#ADVANTAGE : #/CMT# The brake disk is displaced axially opposite to a worm shaft and is arranged on the worm shaft with its rotating end, and hence enables an extremely wear-free operation at high setting accuracy and also ensures to prevent accidental overloads beyond design in the actuator and valve units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an operating device with a torque-limiting brake device. 2 : Operating device 6 : Worm shaft 8 : Worm gear pair 10 : Worm 12 : Worm gear 30 : Brake disk 34 : Non rotating friction body 38 : Rocker arm.
