PLANETARY CARRIER WITH SPRING CLUTCH

摘要

A planetary gear assembly comprising: a housing, which contains: a planetary carrier, a sun gear, at least one planetary gear, a ring gear, a coil spring; an input shaft; and an output shaft. The coil spring extends around at least a portion of the planetary carrier. The coil spring includes a first tang in communication with the ring gear and a second tang in communication with the housing. When torque is applied to the input shaft, the planetary carrier rotates within the coil spring in one or more driving directions so that torque is transferred to the output shaft. When no torque is applied to the input shaft and torque is applied to the output shaft, the coil spring constricts and provides sufficient contact force to the planetary carrier and housing to prevent the planetary carrier from moving relative to the housing in at least one of the driving directions.

1) A planetary gear assembly comprising:
a. a housing which contains:
i. a planetary carrier;ii. a sun gear;iii. at least one planetary gear;iv. a ring gear; andv. a coil spring which extends around all or a portion of the planetary carrier; b. an input shaft; and c. an output shaft;
wherein the coil spring includes a first tang that is in communication with the ring gear and a second tang that is in communication with the housing;wherein when torque is applied to the input shaft, the planetary carrier rotates within the coil spring in one or more driving directions so that torque is transferred to the output shaft; andwherein when no torque is applied to the input shaft and torque in one direction is applied to the output shaft, the coil spring constricts and provides sufficient contact force to the planetary carrier and to the housing to prevent the planetary carrier from moving relative to the housing in at least one of the driving directions.
