Abstract
A buffering mechanism for an automotive starter using planetary gear speed reduction mechanism between a motor and a pinion torque transmission mechanism is disclosed, in which elastic members are provided in spaces defined between circumferentially opposed sides of depressions formed in the outer periphery of a ring gear of the planetary gear speed reduction mechanism and depressions formed in the inner periphery of a member receiving a reaction force.
Claims1
In an automotive starter including a planetary gear speed reduction mechanism between a motor and a pinion torque transmission system, the improvement comprising a machine frame for said system having front and rear halves, a ring gear engaging the inner periphery of said front and rear halves of said frame, a buffering mechanism for said automotive starter including elastic members provided in spaces defined between circumferentially opposed sides of depressions formed in axially divided one half of the outer periphery of said ring gear and depressions formed in the inner periphery of the corresponding half of the machine frame, the other axial half of the ring gear outer periphery being smoothly fitted in the other machine frame half.
