Abstract
The utility model relates to the technical field of sealing devices, in particular to an oil seal comprising an oil seal main body, a rubber spring and a check ring, wherein the rubber spring is arranged at two ends of the oil seal body and is fixedly connected with the check ring which is provided with an annular slot. For the oil seal, the structure is simple, the use is convenient, the practicability is strong, the sealing performance of a rotating shaft is enhanced, the friction resistance is small, the frequency for replacing the oil seal is reduced due to wear resistance, materials are saved, the service life of the oil seal is prolonged, the production efficiency is enhanced, and the promotion and application are easy.
Description
Technical field
The utility model relates to a kind of technical field of seal arrangement, especially a kind of oil sealing.
Background technique
Original oil sealing inwall because and closely cooperating and the corrosion of lubricant oil between the rotating shaft, cause oil sealing to exist wearing and tearing with aging, cause leakage of oil, shortened the working life of oil sealing, must often change oil sealing, reduced manufacturing efficiency.
The model utility content
In order to overcome the easy wear and aging of original oil sealing, working life is short and manufacturing efficiency is low deficiency, the utility model provides a kind of oil sealing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of oil sealing, comprise oil sealing main body, rubber spring and back-up ring, and oil sealing main body two ends are provided with rubber spring, and rubber spring is fixedlyed connected with back-up ring.
According to another embodiment of the present utility model, comprise that further back-up ring is provided with circular groove.
The beneficial effects of the utility model are: this oil seal structure is simple, easy to use, practical, strengthened the sealability at running shaft place, surface friction drag is little, wear-resistant, reduce the replacing frequency of oil sealing, saved material, prolonged the working life of oil sealing, improved manufacturing efficiency, be easy to apply.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. oil sealing main bodys among the figure, 2. rubber spring, 3. back-up ring, 4. circular groove.
Embodiment
As Fig. 1 is structural representation of the present utility model, and this oil sealing comprises oil sealing main body 1, rubber spring 2 and back-up ring 3, and oil sealing main body 1 two ends are provided with rubber spring 2, and rubber spring 2 is fixedlyed connected with back-up ring 3, and back-up ring 3 is provided with circular groove 4.
During use, oil sealing main body 1 two ends are provided with rubber spring 2, when rubber spring 2 is under pressure, rubber spring 2 increases with the area of contact of the mechanical part that needs sealing, good seal performance, be provided with the back-up ring 3 that an astragal has circular groove 4 around the rubber spring 2, the outflow of lubricant oil in the time of can preventing the mechanical part operation.This oil seal structure is simple, and is easy to use, practical, strengthened the sealability at running shaft place, surface friction drag is little, and is wear-resistant, reduced the replacing frequency of oil sealing, saved material, prolonged the working life of oil sealing, improved manufacturing efficiency, be easy to apply.
