Description
Technical field
The utility model relates to Sealing manufacturing technology field, is specifically related to a kind of structure improving sealing of motor oil seal.
Background technique
The position of the bearing rotary such as vehicle bridge, gearbox, motor of light truck and car, generally needs the oil sealing lubricating grease come in stuffing box bearing not leak and prevents outside dust impurity from entering in vehicle bridge or motor.Although the oil sealing of existing structure can meet above-mentioned seal request; but owing to often there will be the situation of eccentric rotary in running shaft; and the resistance to eccentric ability of existing rotary shaft oil seal and trackability poor; therefore during eccentric rotary can there is leakage of oil in oil sealing; cause the sealing effect of oil sealing poor, also have impact on the service behaviour of the parts such as vehicle bridge, gearbox, motor simultaneously.
Model utility content
The utility model object is to provide a kind of structure improving sealing of motor oil seal, to solve many defects that prior art deficiency causes.
A kind of structure improving sealing of motor oil seal, comprise skeleton and sealing lip, elastic support is connected with inside described skeleton, described elastic support is spring-like, and described elastic support is provided with protruding also wrapping frame lower end, and in holding limit structure, described elastic support is provided with the connecting end be connected with skeleton, described elastic support side is provided with sealing lip, and be provided with spring outside described sealing lip, spring is built in elastic support.
Preferably, described sealing lip comprises primary seal lip and secondary sealing lip.
Preferably, described elastic support is rubber material.
Preferably, described elastic support brings out in connection and is provided with re-entrant angle.
Preferably, described elastic support is connected with skeleton by bonding mode.
The utility model has the advantage of, described a kind of structure improving oil sealing sealing, by being located at the elastic support between skeleton and sealing lip, improve the trackability of oil seal structure, improve the resistance to eccentric ability of sealing lip when rotating shaft eccentric rotates, thus improve the sealability of oil sealing, and described elastic support is connected with skeleton bonding mode, described connecting end is provided with re-entrant angle, when adding bonding, elastic support is to the bond area of skeleton, and skeleton lower end is elastically supported body parcel, in conjunction with firm, working life is longer, elastic support inside is located at by described spring, prevent working procedure spring from coming off, improve the stability of oil sealing work.
Accompanying drawing explanation
If Fig. 1 is a kind of sectional view improving the structure of sealing of motor oil seal described in the utility model.
Wherein, 1-skeleton, 2-elastic support, 3-hold limit structure, 4-connecting end, 5-spring, 6-primary seal lip, 7-secondary sealing lip, 8-re-entrant angle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of structure improving sealing of motor oil seal, comprise skeleton 1 and sealing lip, be connected with elastic support 2 inside described skeleton 1, described elastic support 2 is spring-like, described elastic support 2 is provided with protruding also wrapping frame 1 lower end, and in holding limit structure 3, described elastic support 2 is provided with the connecting end 4 be connected with skeleton 1, described elastic support 2 side is provided with sealing lip, be provided with spring 5 outside described sealing lip, spring 5 is built in elastic support 2.
It should be noted that described sealing lip comprises primary seal lip 6 and secondary sealing lip 7.
In this example, described elastic support 2 is rubber material.
In this example, described elastic support 2 brings out in connection and is provided with re-entrant angle 8.
In addition, the logical 2 mistake bonding modes of described elastic support are connected with skeleton 1.
Based on above-mentioned, described a kind of structure improving oil sealing sealing, by being located at the elastic support 2 between skeleton 1 and sealing lip, improve the trackability of oil seal structure, improve the resistance to eccentric ability of sealing lip when rotating shaft eccentric rotates, thus improve the sealability of oil sealing, and described elastic support 2 is connected with skeleton 1 bonding mode, described connecting end 4 is provided with re-entrant angle 8, the bond area of elastic support 2 pairs of skeletons 1 when adding bonding, and skeleton 1 lower end is elastically supported body 2 wraps up, in conjunction with firm, working life is longer, it is inner that elastic support 2 is located at by described spring 5, prevent working procedure spring 5 from coming off, improve the stability of oil sealing work.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in right of the present utility model the change of the above embodiment, modification.
