Abstract
The invention relates to a deep groove ball bearing. The deep groove ball bearing comprises a bearing outer ring, a bearing inner ring, a rolling body, a bearing dust cap and an O-shaped seal ring, and is characterized in that the outer surface of the bearing inner ring is provided with a groove for inserting the O-shaped seal ring, and after the O-shaped seal ring is inserted in the groove, a gap is reserved between the surface of the O-shaped seal ring and the surface at the internal side of the bearing dust cap. The beneficial effects comprise that by installing the O-shaped seal ring at the internal side of the bearing dust cap, dust, oil mist, harmful gases and the like passing through a gap between the bearing inner ring surface and the bearing dust cap surface is blocked by the O-shaped seal ring and cannot enter the interior of the bearing. The bearing is usable under the work conditions of both dustproof and seal requirements, and provides convenience for manufacture of bearings and usage universality of bearings.
Description
Technical field
The present invention relates to a kind of deep groove ball bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Develop into now, the kind of bearing and varied, wherein ball bearing is the one of rolling bearing, and bearing roller is contained in the centre of bearing outer ring and bearing inner race, can bear larger load, be called deep groove ball bearing again.But in the prior art, ball bearing also also exists defect, the dust-proof single selection only had with sealing of such as existing ball bearing, can not the two take into account, and satisfies the demands so be badly in need of now a kind of bearing solving above-mentioned defect.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of deep groove ball bearing.
Described a kind of deep groove ball bearing, comprise bearing outer ring, bearing inner race, rolling element, bearing dustproof cover and O RunddichtringO, the outer surface that it is characterized in that described bearing inner race is provided with the groove embedding O RunddichtringO, after O RunddichtringO embeds groove, between the surface of O RunddichtringO and bearing dustproof cover inner surface, there is gap.
Described a kind of deep groove ball bearing, is characterized in that the height exposing bearing inner race outer surface after described O RunddichtringO embeds the groove of bearing inner race is no less than 2/3 of O RunddichtringO diameter.
Described a kind of deep groove ball bearing, is characterized in that described O RunddichtringO is that the elastic material of rubber or plastics is made.
Beneficial effect of the present invention is: O RunddichtringO is housed inside bearing dustproof cover, through bearing inner race surface with the dust, mist of oil, harmful gas etc. of bearing dustproof cover surface gap after O RunddichtringO stops, cannot Bearing inner be entered.This bearing can dust-proof with the operating mode of seal request under use simultaneously, the versatility requirement that the manufacture of bearing, bearing use is provided convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A portion enlarged view in Fig. 1.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
The present invention includes bearing outer ring 1, bearing inner race 2, rolling element 3, bearing dustproof cover 4 and O RunddichtringO 5, bearing outer ring 1 is arranged at outside bearing inner race 2, rolling element 3 is arranged between bearing outer ring 1 and bearing inner race 2, bearing dustproof cover is provided with between the bearing outer ring 1 of described rolling element 3 both sides and bearing inner race 2, the outer surface of bearing inner race 2 is provided with the groove 6 embedding O RunddichtringO 5, after O RunddichtringO 5 embeds groove 6, gap 8 is had, for contactless between the surface of O RunddichtringO 5 and bearing dustproof cover 4 inner surface 7.Inside bearing dustproof cover 4, O RunddichtringO 5 is housed like this, through bearing inner race 2 surface with the dust, mist of oil, harmful gas etc. of bearing dustproof cover 4 surface gap after O RunddichtringO 5 stops, cannot Bearing inner be entered.
Above-mentioned O RunddichtringO 5 is that the elastic material of rubber or plastics is made.
As preferably, O shape seal ring 5 exposes bearing inner race 2 outer surface height after embedding the groove 6 of bearing inner race 2 is no less than 2/3 of O RunddichtringO 5 diameter, such design had both ensured that O-ring seals 5 can embed in the groove 6 of bearing inner race 2, can also ensure that O RunddichtringO 5 plays sealing effect.
O RunddichtringO is housed inside bearing dustproof cover, through bearing inner race surface with the dust, mist of oil, harmful gas etc. of bearing dustproof cover surface gap after O RunddichtringO stops, cannot Bearing inner be entered.This bearing can dust-proof with the operating mode of seal request under use simultaneously, the versatility requirement that the manufacture of bearing, bearing use is provided convenience.
Claims (3)
1. a deep groove ball bearing, comprise bearing outer ring, bearing inner race, rolling element, bearing dustproof cover and O RunddichtringO, the outer surface that it is characterized in that described bearing inner race is provided with the groove embedding O RunddichtringO, after O RunddichtringO embeds groove, between the surface of O RunddichtringO and bearing dustproof cover inner surface, there is gap.
2. a kind of deep groove ball bearing according to claim 1, is characterized in that the height exposing bearing inner race outer surface after described O RunddichtringO embeds the groove of bearing inner race is no less than 2/3 of O RunddichtringO diameter.
3. a kind of deep groove ball bearing according to claim 1, is characterized in that described O RunddichtringO is that the elastic material of rubber or plastics is made.
