Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of deep groove ball bearing of two sides band dust cover.
Background technique
Current, bearing work had entered a brand-new high-quality fast-developing period already, and bearing has become a kind of very important component in contemporary machinery.The major function of bearing is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Outside the steel ball of bearing is directly exposed to, often on bearing, sets up dust cover, avoid steel ball by the contaminating erosion such as dust, greasy dirt, but between dust cover and bearing inner race, there is larger frictional force, have impact on the work of bearing.
Model utility content
The technical problem that one, will solve
The purpose of this utility model is for the problems referred to above existing for prior art, spy provides a kind of deep groove ball bearing of two sides band dust cover, linear contact lay is formed between dust cover and the outer wall of inner ring, frictional force is little, the normal work of bearing can not be affected, there is larger frictional force between dust cover and bearing inner race in prior art and the defect affecting bearing working to overcome.
Two, technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of deep groove ball bearing of two sides band dust cover, described deep groove ball bearing comprises the coaxial inner ring that arranges and outer ring, and the retainer be arranged between described inner ring and described outer ring and several steel balls be positioned on described retainer; The both sides of described deep groove ball bearing are respectively arranged with dust cover, the outer end of described dust cover is connected to the inwall of described outer ring, the outer wall of described inner ring is stretched in the inner of described dust cover, and and be disposed with seal ring and slide block between the outer wall of described inner ring, described slide block is provided with cone angle towards the side of described inner ring, forms linear contact lay with the outer wall of described inner ring.
Wherein, in the deep groove ball bearing of above-mentioned two sides band dust cover, the inwall of described outer ring is formed with the draw-in groove of arc, and the outer end of described dust cover is connected in described draw-in groove.
Wherein, in the deep groove ball bearing of above-mentioned two sides band dust cover, the outer end of described dust cover is formed as flange, described flange and described draw-in groove close contact.
Wherein, in the deep groove ball bearing of above-mentioned two sides band dust cover, be enclosed with elastic component in described flange, described flange is closely against in described draw-in groove by described elastic component.
Wherein, in the deep groove ball bearing of above-mentioned two sides band dust cover, one end of described seal ring embeds the inner of described dust cover, the other end and described slide block close contact.
Wherein, in the deep groove ball bearing of above-mentioned two sides band dust cover, the inner of described dust cover is formed with groove, and described seal ring is formed as the projection with described groove match near one end of described dust cover the inner.
Three, the beneficial effects of the utility model
Compared with prior art, the outer end of the dust cover in the deep groove ball bearing of a kind of two sides band dust cover of the present utility model is connected to the inwall of outer ring, the inner stretch to inner ring outer wall and and be disposed with seal ring and slide block between the outer wall of inner ring, slide block is provided with cone angle towards the side of inner ring, linear contact lay is formed with the outer wall of inner ring, decrease the friction in working procedure, and stable type is good, substantially prolongs working life.The deep groove ball bearing of a kind of two sides band dust cover of the present utility model, make to form linear contact lay between dust cover and the outer wall of inner ring, frictional force is little, can not affect the normal work of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the deep groove ball bearing of the two sides band dust cover of the utility model embodiment;
Fig. 2 is the A portion enlarged view in Fig. 1;
Fig. 3 is the B portion enlarged view in Fig. 1;
Wherein:
1 is inner ring; 2 is outer ring; 3 is retainer; 4 is steel ball; 5 is dust cover; 6 is seal ring; 7 is slide block; 8 is cone angle; 9 is draw-in groove; 10 is flange; 11 is elastic component; 12 is groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
The structure of the deep groove ball bearing of the two sides band dust cover of the utility model embodiment comprises the coaxial inner ring 1 that arranges and outer ring 2 as shown in Figure 1, and the retainer 3 be arranged between inner ring 1 and outer ring and several steel balls 4 be positioned on retainer 3.
The both sides of deep groove ball bearing are respectively arranged with dust cover 5.As shown in figures 1 and 3, the outer end of dust cover 5 is connected to the inwall of outer ring 2.Particularly, the inwall of outer ring 2 is formed with the draw-in groove 9 of arc, and the outer end of dust cover 5 is connected in draw-in groove 9.In order to dust cover 5 being closely connected to the inwall of outer ring 2, the outer end of dust cover 5 is set to flange 10, this flange 10 and draw-in groove 9 close contact, and is enclosed with elastic component 11 in flange 10, flange 10 is closely against in draw-in groove 9 by elastic component 11.As depicted in figs. 1 and 2, the outer wall of inner ring 1 is stretched in the inner of dust cover 5, and and between the outer wall of inner ring 1, be disposed with seal ring 6 and slide block 7, one end of seal ring 6 embeds the inner, the other end and slide block 7 close contact of dust cover 5.Be formed with groove 12 in the inner of dust cover 5, seal ring 6 is formed as the projection matched with groove 12 near one end of dust cover 5 the inner, and namely by cooperation that is protruding and groove 12, seal ring embeds the inner of this dust cover 5.Slide block 7 is provided with cone angle 8 towards the side of inner ring 1, forms linear contact lay with the outer wall of inner ring 1.Owing to being linear contact lay, reduce frictional force, the normal work of bearing can not be affected, and improve the working life of dust cover 5 and bearing.
As mentioned above, the outer end of the dust cover in the deep groove ball bearing of a kind of two sides band dust cover of the present utility model is connected to the inwall of outer ring, the inner stretch to inner ring outer wall and and be disposed with seal ring and slide block between the outer wall of inner ring, slide block is provided with cone angle towards the side of inner ring, linear contact lay is formed with the outer wall of inner ring, decrease the friction in working procedure, and stable type is good, substantially prolongs working life.
The deep groove ball bearing of a kind of two sides band dust cover of the present utility model, make to form linear contact lay between dust cover and the outer wall of inner ring, frictional force is little, can not affect the normal work of bearing.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
