ABSTRACT:
An emergency drive is a toothed element such as a gear rim, is arranged on a traction sheave of an elevator drive. During emergency operation, the gear rim is driven by means of a pinion of an auxiliary engine. The engine is installed on the elevator drive only during an emergency operation. After emergency operation, the engine is removed from the drive unit. The gear rim may be composed of several layers of interlocked segments. The layers are mutually shifted in a circumferential direction. Each segment consists of laminated/interlocked sheet metal segments, which are, as mass-produced goods, cheaply producible through cutting and punching procedures.
