Starter having overrunning clutch for starting an internal combustion engine

摘要

A starter (1) for starting an internal combustion engine contains an electric motor (2), a driven shaft (4) and a one-way clutch (3) for transmitting a torque of the electric motor (2) to the output shaft (4). The free-wheel coupling consists of an outer coupling part (3a) which, by means of an electric motor (2) is driven, an inner coupling part (10), which with the output shaft (4) is coupled via a wedge, and between the outer coupling part and the inner coupling element arranged rollers (3c). A portion (10a) of the outer coupling part (10), the inner ring of a ball bearing (11) is used, which the inner coupling member (10) is rotatably mounted. A ball - groove (10b), which the bearing balls (11c) is rotatably mounted and lubricant retains therein, is provided on the outer circumference of the inner coupling member (10) is formed. In this way, an original inner ring of the ball bearing (11) are eliminated, without adversely affecting the lubrication function.
