Circumferential damping structure of ring gear seat of starter and starter

Abstract

The invention discloses a starter of a gear ring seat circumferential damping structure thereof. The starter gear ring circumferential damping structure comprises an inner gear ring, a gear ring seat accommodating the inner gear ring, and a driving end cover accommodating the gear ring seat. The outer circumference of the inner gear ring is evenly provided with at least two fixing parts, the outer circumference of the gear ring seat is evenly provided with at least two limit parts, and the inner circumference of the driving end cover is evenly provided with at least two first de-weight areas; the fixing parts are arranged inside the grooves among the limit parts to circumferentially fix the inner gear ring and the gear ring seat; the first de-weight areas and the limit parts are arranged in a nested mode to circumferentially fix the driving end cover and the gear ring seat. The starter and the gear ring seat circumferential damping structure thereof can effectively reduce the impact of the starter on the gear ring seat and the driving end cover during operation.

Description

technical field [0001] The invention relates to a ring gear seat structure, in particular to a ring gear seat circumferential shock absorbing structure and a starter including the structure. Background technique [0002] The reduction system of a planetary reduction starter generally includes the following parts: armature shaft (sun gear), planetary gear, planetary carrier (drive shaft), inner ring gear, ring gear seat and drive end cover. As a part of the motor system, the armature shaft generates torque and transmits the torque to the planetary gear through the sun gear. The planetary gear rotates and drives the planetary gear carrier to rotate, and at the same time transmits the torque to the relatively fixed ring gear, ring gear seat and drive on the end cap. Wherein, the inner ring gear and the ring gear seat can also be made into one. The planetary gear carrier is connected with the starter one-way device to output the torque to the drive gear, and the drive gear mes...
