摘要： A starter for an internal combustion engine includes a motor, a pinion gear connected to the motor to be engaged with a ring gear of the engine. The pinion gear has teeth of a negative addendum modification whose number is larger than a standard gear that has the same outside diameter. Therefore the gear ratio of the pinion gear to the ring gear can be increased without change of the outside diameter thereof.

摘要： A starter for an internal combustion engine includes a planetary gear speed reduction mechanism, a pinion and a pinion drive shaft, a motor, a front housing having a plurality of fastening holes disposed at a circumference and a center casing having approximately the same outside diameter as the motor housing. The center housing is disposed between the motor housing and the front housing to align a motor shaft, the planetary gear speed reduction mechanism and the pinion drive shaft. The diameter of the motor housing is a maximum outside diameter of the fastening bolt less than the diameter of a circumference on which the fastening bolts are formed. Therefore, fastening bolts can be easily inserted into the fastening holes.

The bearing has a plurality of through holes between the inner surface and the outer surface. A housing of the starter has a holding part for holding the bearing. A groove is formed annularly in the inner peripheral surface of the holding part. The groove is communicated with the through holes of the bearing. A seal member is press-fit in the holding part in proximity to a pinion gear side of the bearing. The seal member prevents foreign substances from entering the bearing surface of the bearing and inhibits the flowing out of lubricant from the bearing.

摘要： A starter for an engine is equipped with a planetary gear speed reducer, a restraining mechanism, and a shock absorber which is made up of a rotary disc, a stationary disc, a case, and a load applying mechanism. The load applying mechanism applies a load to the stationary and rotary discs to develop a given degree of friction therebetween. When an excessive torque acts on the rotary disc through the internal gear, the shock absorber induces the rotary disc to rotate against the given degree of friction to absorb the torque to eliminate a physical impact to be exerted on the planetary gear speed reducer. The restraining mechanism restrains the load applying mechanism from moving in a radius direction of the internal thread to avoid undesirable engagement of the load applying mechanism with the internal thread, thereby ensuring the stability in applying the load to the stationary and rotary discs.

摘要： A starter for automotive engines is provided which is equipped with a planetary gear train working as a speed reducer. The starter also includes a partition plate and a thrust washer. The partition plate extends radially of the starter between an electric motor and a planetary gear train to isolate the planetary gear train from a motor chamber. The thrust washer extends radially of the starter in abutment with the partition plate so as to bear a thrust load, as transmitted from the planetary gear train. The thrust washer also includes an outer peripheral portion which is placed between a rear end surface of an internal gear of the planetary gear train and the front end surface of the partition plate and has an elastic mechanism working to elastically urge the internal gear of the planetary gear train frontward in the axial direction of the starter.

摘要： In a starter, a one-way clutch that transmits rotation of a motor to an output shaft has a clutch inner portion. The clutch inner portion has female helical splines in an inner periphery. Also, the clutch inner portion has a stopper at a front end of the female helical splines on the side opposite to the motor. The female helical splines engage with male helical splines formed on a rear end of the output shaft so that the output shaft is slidable in an axial direction. When the male helical splines of the output shaft are brought into contact with the stopper, relative rotation of the helical splines is restricted, thereby to stop the axial movement of the output shaft.
