Abstract
The utility model discloses a back-up ring and hoop combined axial positioning structure including a shaft, a back-up ring, a back-up ring hoop, and an anti-rotating device, the back-up ring includes a first back-up ring and a second back-up ring, a circular groove is arranged in the surface of the shaft, the bottom of the circular groove is provided with an anti-rotating groove, the first back-up ring and the second back-up ring are clamped in the circular groove, an anti-rotating notch is arranged in the inner circular surface of the first back-up ring or the inner circular surface of the second back-up ring, the two ends of the anti-rotating device are respectively clamped in the anti-rotating notch and groove, and the back-up ring hoop sleeves outside the back-up ring. The axial positioning structure can realize axial positioning under the condition that a shaft has no steps.
Description
Technical field
The utility model relates to a kind of position structure, is specifically related to a kind of back-up ring and garter spring combination axial positioning structure.
Background technique
In single countershaft transmission, part on two axle assemblies is various, different parts has certain axial position requirement with respect to the benchmark on two axles, the general employing shaft shoulder also coordinates circlip for shaft to carry out the axially locating of part, but when transmission gear is many, parts on shaft is when more, is subject to the restriction of speed changer centre distance, the diameter of axle can not be too thick, the spring bearing at axle two ends can not be too little, therefore just can not on axle, design abundant step and carry out the axially locating of part.
Model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of back-up ring and garter spring combination axial positioning structure are provided, and this structure can realize axle and in the situation that there is no step, realize axially locating.
As the improvement of such scheme, back-up ring described in the utility model and garter spring combination axial positioning structure comprise axle, back-up ring, back-up ring garter spring and anti-rotation device, back-up ring comprises the first back-up ring and the second back-up ring, the outer surface of axle offers annular groove, the bottom of annular groove offers anti-rotation groove, the first back-up ring and the second back-up ring are connected in annular groove, on the inner ring surface of the first back-up ring or on the inner ring surface of the second back-up ring, offer anti-rotation breach, the two ends of anti-rotation device are connected in respectively in anti-rotation breach and groove, and back-up ring garter spring is set in the outside of back-up ring.
Described anti-rotation device is stop pin or steel ball.
The width of described back-up ring is greater than the width of back-up ring garter spring.
Described the first back-up ring and the second back-up ring are semicircle loop configuration.
Described back-up ring and back-up ring garter spring are all made by metallic material.
The thickness of described back-up ring is identical with the width of annular groove.
The utlity model has following beneficial effect:
Back-up ring described in the utility model and garter spring combination axial positioning structure comprise axle, back-up ring, back-up ring garter spring and anti-rotation device, back-up ring is made up of the first back-up ring and the second back-up ring, the outer surface of axle offers annular groove, the first back-up ring and the second back-up ring are connected in described annular groove, back-up ring garter spring is socketed on described back-up ring, thereby on axle, realize axial location, solved cannot design the spacing shaft shoulder on axle time, circlip for shaft cannot meet again the axial limiting demand of service condition.
