Abstract
The utility model discloses a reducing gear mechanism for starter, including armature shaft, armature shaft gear, transition gear and reducing gear, armature shaft gear suit is at the armature shaft tip, transition gear mesh mutually with the armature gear and parallel arrangement in armature shaft gear lower part, reducing gear includes external gear and internal gear to the external gear of saying so is same ring gear with the internal gear, reducing gear pass through that the external gear meshes with transition gear mutually and parallel arrangement in the transition gear lower part. In this way, the utility model relates to a reducing gear mechanism for starter, its exit velocity is slow, the power output is bigger, is fit for the operating condition that heavy starter was exported slowly to operating condition is more stable in output.
Description
Technical field
The utility model relates to gear mechanism, particularly relates to a kind of reduction gear for starter motor.
Background technique
Gear mechanism is the chief component of starter motor, is mainly used in Power output.The main distinction of retard start starter motor and conventional starter motor is between driving mechanism and armature, installed a set of speed reducer, by speed reducer, moment is passed to overrunning clutch, the speed that can reduce motor increases output torque, reduces the volume and weight of starter motor.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of reduction gear for starter motor, and its output speed is slow, ouput force is larger, is applicable to the working state that heavy starter motor exports slowly, and output services epidemic situation comparison is stablized.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of reduction gear for starter motor, comprise armature shaft, armature shaft gear, transition gear and reduction gear, described armature shaft gear set is in armature shaft end, described transition gear is meshed with armature pinion and is set in parallel in armature shaft gear bottom, described reduction gear comprises external gear and internal gear, and say be external gear and internal gear to be same gear ring, described reduction gear to be meshed with transition gear by external gear and to be set in parallel in transition gear bottom.
In the utility model preferred embodiments, described transition gear inside is provided with jack shaft and is fixed on the polyamide skeleton on jack shaft outer peripheral surface.
In the utility model preferred embodiments, described polyamide skeleton is provided with oil guide slot.
In the utility model preferred embodiments, in described reduction gear, the gear ratio of external gear and internal gear is 3:1.
In the utility model preferred embodiments, described internal gear center portion is provided with transmission conduit, and transmission end of conduit is provided with actuation gear.
In the utility model preferred embodiments, described transmission catheter interior is provided with cooling liquid.
The beneficial effects of the utility model are: a kind of reduction gear for starter motor of the utility model, and its output speed is slow, ouput force is larger, is applicable to the working state that heavy starter motor exports slowly, and output services epidemic situation comparison is stablized.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model for reduction gear one preferred embodiment of starter motor.
