ABSTRACT:
An overrunning clutch designed for use with engine starters and the like whereby the starter may apply its output to start the engine without damage due to overspeed of critical starting motor components after the engine has started and obtained running speed.
The overrunning clutch of this invention is provided with two splines. The first a straight spline which allows axial translation of the starter output shaft and a second helical spline which assists in engagement and disengagement of interlocking face clutch jaws between the input drive shaft and the output drive shaft. A centrifugally restrained clutch engagement spring in combination with the helical spline permits overrunning with minimum wear of the face clutch jaws.
