Title:
ENERGY ACCUMULATING DEVICE FOR CIRCUIT BREAKER OPERATING SPRING
Document Type and Number:
Japanese Patent JPH07122153
Kind Code:
A
Abstract:
PURPOSE: To reduce operation force of a manual handle by interposing a one- way clutch between a shaft and an operation shaft.
CONSTITUTION: A first gear 2 is fixed to a shaft 1B, and a second gear 3 is meshed with the gear 2, and an operation shaft 4 is installed in the shaft center of the gear 3 through a one-way clutch 32. In this one-way clutch 32, even if the center operation shaft is rotated, since the torque is not transmitted to the gear 3 on the outer periphery, the operation force of a manual handle can be reduced sharply.
