Actuating device, especially for fitting in robot tank systems, has gear formed by wormwheel and worm assembly self-locking in direction from output shaft to input shaft, and coupling connected between gear and output shaft

摘要

The actuating device has a gear formed by a wormwheel(12) and worm(11) assembly self-locking in the direction from the output shaft(5) to the input shaft(2). The worm is connected torsionally fixed to the input shaft, and the wormwheel is rotatably mounted on the output shaft. A coupling(13-17) is connected between the gear and output shaft. A manual operating arrangement(18-24) has a predetermined operating travel which by a first section shifts the coupling into the disconnected position, and by a second section operates the output shaft.
