Abstract
Polytetrafluoroethylene oil seal for a dustproof friction surface comprises an oil seal body and a framework arranged on the inner side of the oil seal body and is characterized in that a polytetrafluoroethylene plate is adhered to the bottom of the oil seal body. The polytetrafluoroethylene oil seal for the dustproof friction surface can keep the dustproof friction surface clean, achieve long-time stable dustproof effect, and has simple structure and reasonable design, thereby having good market prospect.
Description
Technical field
The utility model belongs to the oil sealing sealing technical field, is specifically related to a kind of with the oil sealing of polyfluortetraethylene plate as dustproof rubbing surface.
Background technique
Oil sealing is widely used on motor vehicle and the engineering machinery, and it is of a great variety, as be used in the wheel shaft place of wheel wheel limit oil sealing, main subtract oil sealing etc., that oil sealing can play is dustproof, the effect of waterproof, anti-leakage of oil.Especially under operating mode rugged environments such as building site, mine, need the better oil sealing of dustproof and waterproof sealability.Existing oil sealing can only reach slight dustproof effect, in the silt environment, often uses oil sealing and v type rotation envelope shared reaching better dustproof effect, but because silt is easy to cover at metal or rubber friction face early failue.
The model utility content
The purpose of the utility model is the deficiency that overcomes the existence of above-mentioned technology, and a kind of oil sealing that can form dustproof rubbing surface steady in a long-term is provided.
The technological scheme that the utility model is adopted to achieve these goals is following: a kind of teflon rubbing surface oil sealing that prevents dust, and it comprises oil seal body and skeleton, skeleton is arranged on the oil seal body inboard, it is characterized in that the oil seal body bottom is bonded with polyfluortetraethylene plate.
According to the dustproof rubbing surface oil sealing of above-mentioned teflon, it is characterized in that said oil seal body and axle surface of contact are provided with main lip and secondary lip, and this main lip is positioned at secondary lip top.
According to the dustproof rubbing surface oil sealing of above-mentioned teflon, it is characterized in that said main lip inboard is provided with the ring-spring groove, is equipped with ring-spring in this ring-spring groove.
The utility model mainly is the premium properties such as low coefficient of friction, selflubricating and low adsorptive power that make full use of teflon; So use it on formation one plane, oil sealing bottom and as the dustproof lip rubbing surface that seals that rotates of v type; On this face; Dust and mud etc. are difficult for covering, and the dustproof rotation envelope of v type lip do not need grease lubrication, avoid growing greasy filth and pollute and cause sealing early failue.
The beneficial effect of the utility model is: adopt this oil sealing can keep the cleaning of dustproof rubbing surface, realize the long-term stability of dustproof effect, and product structure is simple, reasonable in design, therefore has market prospects preferably.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-oil sealing body, 2-skeleton, 3-polyfluortetraethylene plate, 4-master's lip, the secondary lip of 5-, 6-spring.
Embodiment
To combine accompanying drawing that the technological scheme of the utility model is further specified below, but the utility model is not limited in following mode of execution.
As shown in Figure 1: the teflon rubbing surface oil sealing that prevents dust, it comprises oil seal body 1 and skeleton 2, and on oil seal body 1 and axle surface of contact, establishes a main lip 4 and a secondary lip 5, and main lip 4 is positioned at the top of secondary lip 5.Said main lip 4 internal layers are provided with a ring-spring groove that is used for mounting spring 6.Said skeleton 2 is arranged on oil seal body 1 inboard.Oil seal body 1 bottom is bonded with polyfluortetraethylene plate 3.
The utility model mainly is the good characteristics such as low coefficient of friction, selflubricating and low adsorptive power that make full use of teflon; Therefore form the lip rubbing surface of a plane as the dustproof rotation envelope of v type in the oil sealing bottom; On this face, dust and mud etc. is difficult for covering, and the dustproof rotation envelope of v type lip does not need grease lubrication; Avoid growing the greasy filth pollution and cause sealing early failue, reach dustproof effect steady in a long-term.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Therefore on the basis of the utility model, do not pay creative work modification, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
