Drive device, e.g. for driving spinning pump for making textile fibres

摘要

The drive device includes the motor, the reduction gear and the coupling, in which the coupling halves (10,11) are connected together by a cross-pin (12). The coupling half on the drive side can be directly blocked by an automatically triggered blocking device. The blocking device consists of a spring-loaded bolt (13) which can be released from its operating position by rotating the two coupling halves with respect to each other, whereupon the blocking bolt moves against an independent, fixed stop.
