Abstract

The utility model discloses a retainer ring, which comprises a retainer ring body. An assembly shaft hole is arranged in the middle of the retainer ring body. Oil grooves are arranged on two end faces of the retainer ring body. Two ends of each oil groove extend to the outer circumference of the retainer ring body and the assembly shaft hole in the middle of the retainer ring body. By means of the structure, the oil grooves are additionally disposed on the two end faces of the retainer ring body, lubricating oil and the like can be added into the oil grooves, accordingly, users can add the lubrication oil and the like between the retainer ring body and a shaft according to requirements in due time, sufficient lubrication of the shaft and other parts on the shaft can be kept, and the problem that the shaft and the other parts on the shaft are adhered with each other due to external reasons such as long-term oxidation, corrosion and the like so as to affect normal operation. Accordingly, service lives of all parts are effectively prolonged, and the shaft and the other parts on the shaft are disassembled conveniently.

Description

A kind of back-up ring

Technical field

The utility model relates to a kind of back-up ring.

Background technique

Back-up ring is a major criterion spare on the field of mechanical technique, is a kind of cast parts that are fastened on the axle, is used to prevent to be contained in other part plaies on the axle.Because the back-up ring extended immobilization is assemblied on the axle; Therefore back-up ring easily the influence of outside causes such as long oxidation, corrosion under and with axle or spool on other parts be bonded together; The normal operation that influence axle or axle are gone up other parts; Shortened the working life of each part, the dismounting of also going up other parts for axle is simultaneously made troubles.

Summary of the invention

To the deficiency of existing technology, the utility model provide a kind of can be antirust and working life long back-up ring.

For realizing above-mentioned purpose; The utility model provides a kind of back-up ring; Comprise the back-up ring body; The centre of said back-up ring body is provided with the assembling axis hole, and the two ends end face of said back-up ring body is provided with oil groove, and the two ends of said oil groove extend to the outer peripheral surface of back-up ring body and the assembling axis hole in the middle of the back-up ring body respectively.

The beneficial effect of the utility model is: adopt said structure; Owing on the end face of the two ends of back-up ring body, set up the oil groove that can add lubricated wet goods; Therefore the past back-up ring body that the user can be in good time as required adds lubricated wet goods each other with axle; But the sufficient lubrication that retainer shaft and axle are gone up other parts; Prevent it under the effect of outside causes such as long oxidation, corrosion, to be bonded together each other and influence normal operation, thereby prolonged the working life of each part effectively that the dismounting of going up other parts also for axle and axle brings convenience.

It is some that the utility model can further be set to the oil groove quantity that said back-up ring body two ends end face is provided with, and several oil grooves are circumference uniform distribution.

Embodiment

Provided a kind of back-up ring like Fig. 1, shown in 2; Comprise back-up ring body 1; The centre of said back-up ring body 1 is provided with assembling axis hole 11; Be evenly distributed in three oil grooves 121 on the two ends end face 12 of said back-up ring body 1 respectively, the two ends of said oil groove 121 extend to the outer peripheral surface 13 of back-up ring body 1 and the assembling axis hole 11 in the middle of the back-up ring body 1 respectively.

Adopt said structure; Owing on the two ends of back-up ring body 1 end face 12, set up the oil groove 121 that can add lubricated wet goods; Therefore the past back-up ring body 1 that the user can be in good time as required adds lubricated wet goods each other with axle; But the sufficient lubrication that retainer shaft and axle are gone up other parts; Prevent it under the effect of outside causes such as long oxidation, corrosion, to be bonded together each other and influence normal operation, thereby prolonged the working life of each part effectively that the dismounting of going up other parts also for axle and axle brings convenience.

Claims
