Abstract

PURPOSE:To form a starter into a hermetically sealed system as well as to prevent it from influence of dust and water from the outside, by constituting an output shaft of a planetary gear drive from two types of spline parts and a smoothing shaft part, in case of a device which installs the planetary gear drive as a reduction gear mechanism. CONSTITUTION:When a shaft 3 rotates as an armature 2 of a motor 1 is set in motion, torque is transmitted to a planetary arm 9 at the specified speed reducing ratio via an armature pinion 4 and a planetary gear drive consisting of an internal gear ring gear 6 and a planetary gear 7. In this case, the planetary arm 9 is fitted in a spline part 10a installed at the left end of a pinion shaft 10 serving as an output shaft. In addition, a clutch sleeve 19 of a roller clutch 17 transmitting power of a starter to one direction is engaged with a helical spline 10b installed in the central part of the pinion shaft 10. Likewise, a pinion 20 of the roller clutch 17 makes a bearing 21 installed in the inner cylinder get supported on a smoothing shaft part 10c installed at the right end of the pinion shaft 10.

As shown in Fig. 1 of Utility Model Application No. 58-116760, which aims to downsize the drive device of an internal combustion engine for automobiles, a planetary reduction mechanism is used to make the rotation axis of the motor and the pinion coaxial. A reduction starter has been proposed, which is smaller in size by 1J compared to the so-called two-shaft reduction starter using a spur gear reduction device known from Japanese Patent Application Laid-open No. 49-130237.

However, as is clear from publicly known examples, coaxial starch reduction starters using this planetary reduction mechanism are open around the pinion part that transmits power to the ring gear of the engine, so dust and water from the outside cannot escape. However, there are problems such as the pinion transfer section becoming stuck due to rust, water intrusion into the magnet switch, and furthermore having a significant negative effect on the durability of the planetary reduction mechanism section, so improvements in this area have been desperately desired.
