Abstract
The utility model relates to a kind of bearing outer ring, circumferentially be provided with the groove that slides for rolling element on its inwall, outer wall has tapering, described groove is near the less end of outer diameter of bearing outer ring, circumferentially be provided with one deck step on the inwall of the less correspondence of the outer diameter of bearing outer ring, circumferentially be provided with two-layer step on the inwall of the bigger correspondence of the outer diameter of bearing outer ring, bearing outer ring outer wall and joint, upper and lower plane also are provided with tangent cambered surface.The outer wall of bearing outer ring by original cylindric certain tapering that changes into, improved the soundness that the force bearing point of the bearing of forming is installed by it, intensity also is enhanced, the design of multilayer step on the bearing outer ring inwall simultaneously, further improved the sealability of bearing, it is more remarkable to make it performance oil-proof, dust protection.
Description
Technical field
The utility model relates to a kind of bearing outer ring, relates in particular to firm, the strengthened bearing outer ring of a kind of force bearing point.
Background technique
Its basic structure of the bearing of selling on the market is made up of outer ring, inner ring, one group of rolling element and retainer.The appended part of its supporting Internal and external cycle carries out relative movement and bears certain radial load and axial load.The outer diameter at general used two, outer ring is identical at present, and when being used on some machinery, force bearing point is not very firm, and intensity is also not enough.
Summary of the invention
The utility model mainly is to have solved existing bearing outer ring the shaft strength point of forming is installed is not technical problem very firm, that insufficient strength is big; Provide a kind of and can make the raising of shaft strength point soundness, strengthened bearing outer ring.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: bearing outer ring of the present utility model, circumferentially be provided with the groove that slides for rolling element on the inwall, and outer wall has tapering.Just the diameter of outer wall one end has improved the soundness of the force bearing point of the bearing of forming being installed by it greater than the diameter of the other end, has also strengthened intensity.
As preferably, described groove is near the less end of outer diameter of bearing outer ring.Further improved the soundness of shaft strength point.
As preferably, inwall two of described bearing outer ring is circumferentially with one deck step respectively, can seal ring be installed thereon, and the bearing seal that makes bearing outer ring and inner ring, rolling element, retainer assembly is guaranteed.
As preferably, also be provided with one deck step on the inwall of the long correspondence of described bearing outer ring outer diameter, be installed in the groove that also correspondingly has two circles to mate on this seal ring, further improve the sealability of bearing, the performance oil-proof, dust protection that the bearing that makes installation form has is more remarkable.
As preferably, described bearing outer ring outer wall and joint, upper and lower plane also are provided with tangent cambered surface, make outer wall and upper and lower interplanar smooth transition, increase the aesthetic property of bearing outer ring.
The beneficial effects of the utility model are: the outer wall of bearing outer ring by original cylindric certain tapering that changes into, improved the soundness that the force bearing point of the bearing of forming is installed by it, intensity also is enhanced, the design of multilayer step on the bearing outer ring inwall simultaneously, further improved the sealability of bearing, it is more remarkable to make it performance oil-proof, dust protection.
Description of drawings

Fig. 2 is a kind of elevational schematic view of the present utility model.
1. grooves among the figure, 2. step, 3. cambered surface.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the bearing outer ring of present embodiment, its outer wall has tapering, be that outer wall one end diameter is greater than the other end diameter, circumferentially be provided with the groove 1 that slides for rolling element on the inwall, groove 1 is near the less end of outer diameter of bearing outer ring, circumferentially be provided with one deck step 2 on the inwall of the less correspondence of the outer diameter of bearing outer ring, circumferentially be provided with two-layer step 2 on the inwall of the bigger correspondence of the outer diameter of bearing outer ring, bearing outer ring outer wall and joint, upper and lower plane also are provided with tangent cambered surface 3.When the bearing outer ring of present embodiment and inner ring, rolling element, retainer, seal ring install form bearing after, make the soundness of force bearing point of this bearing improve, intensity enhancing, better tightness, performance oil-proof, dust protection is more remarkable.
Claims (6)
1. a bearing outer ring circumferentially is provided with the groove (1) that slides for rolling element on the inwall, it is characterized in that the outer wall of described bearing outer ring has tapering.
2. bearing outer ring according to claim 1 is characterized in that the outer diameter less end of described groove (1) near bearing outer ring.
3. bearing outer ring according to claim 1 and 2 is characterized in that inwall two of described bearing outer ring is circumferentially with one deck step (2) respectively.
4. bearing outer ring according to claim 3 is characterized in that also being provided with one deck step (2) on the inwall of described bearing outer ring outer diameter than a long correspondence.
5. bearing outer ring according to claim 1 and 2 is characterized in that described bearing outer ring outer wall and joint, upper and lower plane also are provided with tangent cambered surface (3).
6. bearing outer ring according to claim 3 is characterized in that described bearing outer ring outer wall and joint, upper and lower plane also are provided with tangent cambered surface (3).
