Drive-sided retaining torque reducing method for holding shaft generator, involves using shear force exerted on shaft generator to press movable unit against fixed unit, and using friction force as part of retaining torque of generator

摘要

The method involves arranging a fixed unit in a position proximate to a movable unit e.g. pivot (32), in a direction in which a friction force is exerted. A shear force exerted on a shaft generator (30) and produced by a load torque is used to press the movable unit against the fixed unit, where the load torque is exerted on an output gear wheel for rotating with a reduced speed. The friction force is produced between the movable unit and the fixed unit. The friction force is used as a part of a drive-sided retaining torque of the shaft generator. An independent claim is also included for a rotation actuator comprising a motor.
