ABSTRACT:
Driving machine for lifts. In this simply and compactly constructed driving machine, damages caused by axle sagging and deformations of teeth, which occur during peak loadings, of a transmission are avoided and for this purpose, in the drive unit of this invention the drive pulley is rotatably journalled on one end of a stationary axle, which in turn is fastened on a bearing block arranged on the base plate of a machine frame with the drive unit including a transmission, an electrical motor, a brake and a rotation transmitter being arranged co-axially overhung or cantilevered at the drive pulley and secured against rotation by two elastic torque stays attached to the machine frame, with adjustable damping elements installed in the torque stays enabling a load-moment-dependent deflection of the drive unit in the sense of rotation and thereby also providing a load measurement at the drive unit.
