Title: Spring clutch
Inventor: OKANDA MASAO
IPC: F16D43/14
Filed: 1988-08-12
Abstract: PURPOSE:To get rid of slippage at the time of low speed by fitting one coil spring between an input shaft and an output shaft and installing the output side end portion thereof on an output shaft while engaging the other end portion with a claw which swings by centrifugal force. CONSTITUTION:The output shaft side end portion 12a of a coil spring 12 which is fitted between an output shaft 2 and an input shaft 1 is installed on the output shaft 2 by a pin 13. A centrifugal claw 14 is installed on the outside face of a magnet rotor 6 provided on the input shaft 1 by means of a pivotal pin 15 interposing a biased spring 16. At the time of the rotating speed above a defined value of an input shaft 1, the rear end portion 14b of the centrifugal claw 14 is moved outward by centrifugal force while the front end portion 14a is engaged with the bent portion 12b of the coil spring 12. In this condition, the coil spring 12 windingly fastens the input shaft 1 and output shaft 2 in a body, transmitting the rotation of the input shaft 1 side to the output shaft 2 as it is. At the time of low speed rotation, the centrifugal claw 14 is removed from the engaging portion 12b and the winding fastening is loosened without causing slippage.
