Abstract
The utility model relates to a planetary axle structure for a starter, and the inner hole of the planetary axle is provided with a rolling bearing. The utility model reduces the friction of an armature to the rolling bearing when the armature rotates, improves the rotary speed and power, reduces the friction, prolongs the service life of the starter and lowers the noise compared with the prior starter.
Description
Technical field
The utility model is a kind of starter motor planet wheel shaft structure.
Background technique:
The starter motor structure mainly is made of parts such as casing, armature, magnetic switch, driving end cap, shift fork, planet wheel shaft, one-way element, brush covers at present.When starter motor was started working, the armature rotation drove the planet wheel shaft rotation, and one-way element is equipped on the planet wheel shaft, with planet wheel shaft rotation because the effect of magnetic switch, one-way element at the drive lower edge of shift fork transmission shaft to front slide, with the flywheel engagement of motor, carry out work.
Vehicle starter planet wheel shaft endoporus is installed copper sheathing at present, when armature rotates, can produce mechanical loss, has reduced rotating speed and power, influences the performance of starter motor, has reduced the working life of starter motor, but also produces noise.
Summary of the invention:
The purpose of this utility model is to solve above-mentioned existing existing problem, and a kind of raising rotating speed is provided, and power increases the service life, and reduces a kind of starter motor planet wheel shaft structure of noise.
The utility model is achieved in that planet wheel shaft endoporus installation rolling bearing.
With the friction of bearing, compare with present starter motor and to have improved rotating speed and power when advantage of the present utility model has been to reduce the armature rotation, and rub and reduced, also prolonged the working life of starter motor, reduced noise.
