Bidirectional clutch gearbox for high voltage switch

Abstract

The invention relates to a bidirectional clutch gearbox for a high voltage switch. The gearbox comprises a speed-reducing motor and a frame body, wherein a pinion is arranged on an output shaft of the speed-reducing motor; a clutch mechanism is arranged on the frame body and driven by the pinion; the gearbox is characterized in that: the clutch mechanism comprises a clutch gear, a clutch plate, aspring and an output wheel sleeved on a revolving shaft in turn; the clutch gear is in engaged transmission with the pinion; corresponding grooves are uniformly distributed on adjacent surfaces of the clutch gear and the clutch plate; steel balls are arranged in two opposite grooves; the outer circumference of the clutch plate is provided with a groove in which a spring clamp is arranged; one endof the spring is pushed against the side face of the clutch plate, and the other end of the spring is pushed against the side face of the output wheel so that the spring acts a clutching effect; concave and convex grooves on opposite surfaces of the clutch plate and the output wheel are in matching transmission with each other. The gearbox has skillful and reasonable structure and flexible and convenient operation. When the high pressure switch needs manual operation, the speed-reducing motor does not rotate so that the difficulty of manual operation is lowered.

Description

technical field [0001] The invention relates to a high-voltage switch accessory, in particular to a bidirectional clutch gearbox for a high-voltage switch. Background technique [0002] Opening and closing are two basic actions of high-voltage switches. Nowadays, the opening and closing actions of many high-voltage switches often need to be realized by the forward and reverse rotation of the motor. In order to ensure the reliability of the high-voltage switch, it is necessary to configure electric and manual Two sets of mechanisms, so that in case of failure of the electric mechanism, the task can be completed manually in time. In the prior art, when the switch is opened and closed manually, the motor and the reduction box are often driven to rotate together , causing the torque of manual operation to be very large, and the operation is laborious, which affects the normal operation of the switch. Contents of the invention [0003] The object of the present invention is to...
