Abstract
A drive mechanism for a circuit breaker has a spring which is to be tensioned by means of a shaft. On said spring sits a clamp-roll freewheel as a directional lock, whose outer part is connected via a flexible strip traction member to one or more eccentric members. The clamp rollers can be pressed out of their operating position by means of cage disks, which occurs upon reaching the end position of the spring-tensioning shaft by means of a release lever in connection with toggle levers.
Claims13
A drive mechanism for a circuit breaker having an energy storage spring tensionable by means of a crank pin seated upon a shaft rotatable by a motor through a first rotatingly driveable eccentric member by a directional coupling seated on the shaft, comprising:
- a cooperating pair of contacts operable by said energy storage spring;
- a flexible traction member connected to the directional coupling;
- and
- an additional eccentric member seated on a shaft of a hand lever, located between the first eccentric member and the directional coupling, said additional eccentric member being at least partially wrapped around by the traction member.
