A motor energy storage device for a universal circuit breaker operating mechanism

Abstract

The invention relates to a motor energy storage device for a universal type circuit breaker operating mechanism. The motor energy storage device comprises a motor, a bracket A, a tower type gear, a gear, a worm, a bracket B, a tension spring, a stopper, a turbine, a planetary gear set, an internal gear, a plate, nuts, screws and a micro switch; the bracket A is provided with a motor mounting hole and a gear shaft; the motor is mounted in the mounting hole of the bracket A; the motor is provided with a motor shaft gear; the bracket B is provided with a mandrel and mounting screw columns; the bracket A and the bracket B are fixedly connected with each other through bolts; the worm is mounted between the bracket A and the bracket B, and can rotate flexibly; the tower type gear is mounted on the gear shaft through a shaft hole 1; the tower type gear can flexibly rotate on the gear shaft; and the gear A is fixedly mounted on an upper shaft end of the worm through a hole A. The motor energy storage device of the invention has the advantages of small size and compact structure; and with multi-stage gear reduction adopted, the motor energy storage device further has the advantage of large reduction ratio and relatively low manufacturing cost.

Description

technical field [0001] The invention belongs to the field of electromechanical manufacturing, in particular to a motor energy storage device for a universal circuit breaker operating mechanism. Background technique [0002] The structure of the existing motor energy storage device for the operating mechanism of a universal circuit breaker generally includes: a motor, a gear reduction device, an energy storage medium (spring), a stopper (closing lock) and a micro switch. The motor provides power, reduces the speed through the gear reduction device, increases the torque, and stretches, compresses or rotates the energy storage medium (spring) to store energy. When the energy storage mechanism quickly turns to the stop position, the micro switch acts and the motor current is reduced Cut off, the energy storage mechanism finally stops at the stop position, and the output force of the energy storage mechanism acts on the stop (closing lock). During use, it was found that the spac...

Problems solved by technology

During use, it was found that the space layout of the device is not compact and takes up a lot of space. Moreover, due to the unsatisfactory deceleration effect, the torque of the energy storage mechanism is not large enough. Under the action of motion inertia, the output force of the energy storage mechanism often cannot act well on the stop ( closing lock) on
