Servo drive torque setting and display device - has torque sensor on rocker arm shaft, with display disc and cam at each end operating limit switches

摘要

The device is intended for a servo drive with a worm gear whose worm is held by a spring at the middle of the worm gear. A torque sensor follows the worm movement and operates limit switches for open and closed positions. The torque sensor (11) is rigidly mounted on a rotatable shaft (5a) carrying a rocker arm (6) with a shaft (7) at each end, rotatable in it with friction. Each shaft (7) carries a display disc (3) and an eccentric (2) operating a limit switch.
