Abstract
The utility model relates to a sealing component, in particular to an oil seal of a vibration damper. The oil seal comprises a primary sealing lip, a secondary sealing lip and a dust sealing lip, wherein the primary sealing lip, the secondary sealing lip and a shaft of the vibration damper are in an interference fit; at least two convex parallel textures are arranged at each lip port of the primary sealing lip and the secondary sealing lip; and lubricating oil is stored among the convex parallel textures. The oil seal is good in sealing effect, and is capable of prolonging the service life of the oil seal and effectively preventing the vibration damper from failing, as well as meeting the requirements of an electric locomotive and a metro vehicle and the like on the service life of the vibration damper.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of vibration damper oil sealing.
Background technique
As shown in Figure 1 as the shock absorber fluid front cover that electric locomotive and railcar use.Along with improving constantly of electric locomotive and railcar vehicle performance; At present, the life requirements of vibration damper is to reach to use 2 years or damping 500,000 times, in the vibration damper oil sealing shown in Fig. 1; If the magnitude of interference between the primary seal lip of oil sealing and secondary sealing lip and the damper shaft is bigger than normal; In the time of can causing the damper shaft to-and-fro motion and the dry friction of oil sealing lip, cause the oil sealing life-span to reduce defective shock absorber; If the magnitude of interference between the primary seal lip of oil sealing and secondary sealing lip and the damper shaft is less than normal, not only can reduces the sealing effect of oil sealing, and cause oil sealing after using certain hour, to cause oil sealing leakage of oil, defective shock absorber easily because of sizing material elasticity.
The model utility content
The purpose of the utility model is to have proposed a kind of vibration damper oil sealing, and its good sealing effect has prolonged working life of oil sealing, has prevented defective shock absorber effectively, has satisfied the requirement in working life to vibration damper such as electric locomotive and railcar.
The utility model is that the technological scheme below adopting realizes: a kind of vibration damper oil sealing; Comprise primary seal lip, secondary sealing lip and envelope dirt lip; Be interference fit between primary seal lip and secondary sealing lip and the damper shaft; Wherein, the lip place of said primary seal lip and secondary sealing lip is provided with at least two parallel lines of convexity respectively, stores lubricant oil between the protruding parallel line.
The beneficial effect of the utility model is: through the lip place at primary seal lip and secondary sealing lip many parallel lines of convexity are set respectively; And store lubricant oil between the protruding parallel line; Can suitably increase the magnitude of interference between primary seal lip and secondary sealing lip and the damper shaft; Under the lubrication of lubricant oil; The oil sealing life-span that can prevent effectively to cause with the dry friction of primary seal lip and secondary sealed lip in the damper shaft to-and-fro motion process reduces and defective shock absorber, has satisfied the requirement in working life to vibration damper such as electric locomotive and railcar.
Description of drawings
Fig. 1 is the half sectional view of existing vibration damper oil sealing;
Fig. 2 is the half sectional view of vibration damper oil sealing in the utility model;
Fig. 3 is an A place partial enlarged drawing among Fig. 2.
Among the figure: 1 primary seal lip; 2 protruding parallel lines; 3 secondary sealing lips; 4 envelope dirt lips.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 2 and Fig. 3 are the described vibration damper oil sealing of the utility model.This oil sealing comprises spring, primary seal lip 1, secondary sealing lip 3 and envelope dirt lip 4; Be interference fit between primary seal lip 1 and secondary sealing lip 3 and the damper shaft under the elastic force effect of spring; Thereby played seal action, dust excluder lips 4 is mainly used in and prevents that extraneous impurity such as dust from getting in the lubricant oil.At the lip place of primary seal lip 1 and secondary sealing lip 3 many parallel lines 2 of convexity are set respectively, store a certain amount of lubricant oil between the protruding parallel line 2.At this moment; Can suitably increase the magnitude of interference between primary seal lip 1 and secondary sealing lip 3 and the damper shaft; Under the lubrication of lubricant oil, can not cause the dry friction of primary seal lip and secondary sealed lip in the damper shaft to-and-fro motion process, thereby prolong the working life of oil sealing; Prevent defective shock absorber, satisfied the requirement in working life to vibration damper such as electric locomotive and railcar.
