Description

A kind of bearing
Technical field
The utility model relates to mechanical fitting field, is specifically related to a kind of bearing.
Background technique
Bearing is a kind of very important component in contemporary machinery, and its major function is supporting rotating shaft or other moving body, guiding rotate or move and bear by axle or parts on shaft transmission and load.The existing tapered roller bearing in market is to be all made up of four large parts such as outer ring, inner ring, retainer, tapered rollers, in the ordinary course of things, tapered roller bearing is that paired mounting is on the two ends of host work axle, when bearing working, dust and dirt can enter bearing, cause bearing damage, reduce bearing working life.But the sealing deficiency of existing tapered roller bearing, in the running, some dusts and the dirt gap between can gap or Internal and external cycle between axle and axis hole enters in bearing bearing, can cause the damage of bearing, and impact is worked normally.
Model utility content
In order to overcome the deficiency of background technique; the utility model provides a kind of bearing; mainly solve the problem of the dustproof antifouling poor performance of existing bearing; the dustproof antifouling property of this bearing is good; can not only prevent dust to the gap between the Internal and external cycle of bearing and roller antifouling, also well prevent that dust and dirt from can enter in bearing in the gap between axle and axis hole, such design; well comprehensively protect bearing, ensured its normal working efficiency.
The technological scheme that the utility model adopts is, a kind of bearing, comprise bearing body, bearing body comprises outer ring, tapered roller, retainer, inner ring, described inner ring is provided with axis hole, described retainer is located between outer ring and inner ring, described tapered roller is located in retainer, described bearing body is provided with installation sleeve, described installation sleeve comprises main part, bearing seal portion and for the shaft sealing of seal shaft and bearing connection part between the two, bearing seal portion and shaft sealing are all towards bearing body one side setting, described shaft sealing one end is fixedly connected with main part, the other end forms the shaft sealing lip that can fit tightly with axle.
By adopting technique scheme, the setting of bearing seal lip, lug boss and shaft sealing on installation sleeve, make the gap between Internal and external cycle and the roller of installation sleeve to bearing, comprehensive sealing has been carried out in gap between axle and axis hole, well prevent that dust and dirt from entering in bearing, be difficult for allowing bearing impaired, well ensured the normal working efficiency of bearing, the life cycle that has also extended bearing.
The technological scheme that the utility model adopts is: between described bearing seal portion and bearing body, be provided with seal ring, seal ring is provided with lug boss towards a side of bearing body, lug boss interference fit is between inner ring and retainer, lug boss is provided with hollow slot towards a side of installation sleeve, and installation sleeve is provided with the positioning part that embeds hollow slot; Described installation sleeve is provided with bearing seal lip, and bearing seal lip seal is between outer ring and retainer.
By adopting technique scheme, specialize the sealing configuration between sealing configuration, inner ring and the installation sleeve between outer ring and installation sleeve, such structure compares and simply installation sleeve and Sealing is carried out to gluing, sealing, has stronger sealing.
The technological scheme that the utility model adopts is: between described bearing seal lip and lug boss, form and be connected with the mutual conflicting type of retainer.
By adopting technique scheme, retainer is conflicted and is connected with installation sleeve, and lug boss is between interference fit and inner ring and retainer, and retainer can closely and be reliably connected with installation sleeve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at A place in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1 and Figure 2, a kind of bearing, comprises bearing body 1, bearing body 1 comprises outer ring 11, tapered roller 13, retainer 14, inner ring 12, inner ring 12 is provided with axis hole 121, and retainer 14 is located between outer ring 11 and inner ring 12, and tapered roller 13 is located in retainer 14;
Bearing body 1 is provided with installation sleeve 2, and installation sleeve 2 comprises main part 21, bearing seal portion 22 and the shaft sealing 23 for seal shaft and bearing connection part between the two, and bearing seal portion 22 and shaft sealing 23 are all towards bearing body 1 one side settings;
Main part 21 is the ring structure with through hole, and the size shape of the through hole of main part 21 and axis hole 121 is identical and position is corresponding;
Between bearing seal portion 22 and bearing body 1, be provided with seal ring 3, seal ring 3 is provided with lug boss 31 towards a side of bearing body 1, lug boss 31 interference fit are between inner ring 12 and retainer 14, lug boss 31 is provided with hollow slot 32 towards a side of installation sleeve 2, and installation sleeve 2 is provided with the positioning part 24 that embeds hollow slot 32; Described installation sleeve 2 is provided with bearing seal lip, and bearing seal lip seal is between outer ring 11 and retainer 14; Between bearing seal lip and lug boss 31, form and be connected with the mutual conflicting type of retainer 14;
