Abstract
The utility model discloses a kind of energy-conservation bearing, comprise inner ring, outer ring, retainer, dust cover, jump ring and several balls; Described inner ring and outer ring are coaxially put, described ball to be arranged on retainer and and retainer be together arranged between inner ring and outer ring, this ball annular is uniform and on the disc of embedded inner ring and outer ring, the periphery of described inner ring and the inner headed face of outer ring include step breach and annular groove respectively, the two ends of described dust cover lay respectively on step breach and annular groove, and described annular groove and dust cover are connected by jump ring and fix; Described step breach contacts with dust cover.Energy-conservation bearing of the present utility model, can reduce the ouput force that outer ring is rotated, and lubrication effect also significantly promotes.
Description
Technical field
The utility model belongs to mechanical revolving part apparatus field, is specifically related to a kind of energy-conservation bearing.
Background technique
Existing bearing includes inner ring, outer ring and dust cover, there is gap between described outer ring and dust cover and between outer ring and dust cover, therefore dust allows and easily enters in this gap, so can affect lubrication effect very much.And dust cover is generally fixedly connected with outer ring, so dust cover can be driven to rotate, so relative to adding the ouput force making outer ring rotate while outer ring rotates.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model will prevent dust from affecting sealing effect and reduce the ouput force of outer ring rotation.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of energy-conservation bearing, comprises inner ring, outer ring, retainer, dust cover, jump ring and several balls; Described inner ring and outer ring are coaxially put, described ball to be arranged on retainer and and retainer be together arranged between inner ring and outer ring, this ball annular is uniform and on the disc of embedded inner ring and outer ring, the periphery of described inner ring and the inner headed face of outer ring include step breach and annular groove respectively, the two ends of described dust cover lay respectively on step breach and annular groove, and described annular groove and dust cover are connected by jump ring and fix; Described step breach contacts with dust cover.
Described dust cover is provided with a wear-resistant sleeve relative to one end of step gap position, the surface contact of described wear-resistant sleeve and step breach.
Described dust cover includes the glue be connected with annular groove relative to one end of ring groove position.
Described dust cover includes the region of a storage jump ring relative to one end of ring groove position.
The periphery shape of described outer ring is circular arc.
The material of described wear-resistant sleeve is emery.
(3) beneficial effect
Energy-conservation bearing of the present utility model, by one end of dust cover is fixedly connected with inner ring, thus dust cover can not be driven to rotate when outer ring rotates, thus decrease the ouput force of outer ring, so more energy-conservation, and dust cover two ends contact with inner ring and outer ring the gap closing made between it respectively, so effectively avoid entering of dust, therefore improve lubrication effect.

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 are not used for limiting scope of the present utility model.
The energy-conservation bearing of one as shown in Figure 1-Figure 3, comprises inner ring 1, outer ring 2, retainer 3, dust cover 4, jump ring 6 and several balls 5.The periphery shape of described outer ring 2 is circular arc.Described inner ring 1 is coaxially put with outer ring 2, described ball 5 to be arranged on retainer 3 and and retainer 3 be together arranged between inner ring 1 and outer ring 2, uniform and the embedded inner ring 1 of this ball 5 annular is with on the disc of outer ring 2, the periphery of described inner ring 1 and the inner headed face of outer ring 2 include step breach 7 and annular groove 8 respectively, the two ends of described dust cover 4 lay respectively on step breach 7 and annular groove 8, described annular groove 8 and dust cover 4 are connected by jump ring 6 and fix, described step breach 7 contacts with dust cover 4, so make dust cover 4 be driven to rotate when outer ring 2 rotates, because this reducing the ouput force decreasing outer ring, so more energy-conservation, and dust cover 4 two ends contact with inner ring 1 and outer ring 2 gap closing made between it respectively, so effectively avoid entering of dust, therefore improve lubrication effect.
Described dust cover 4 is provided with relative to one end of step breach 7 position the wear-resistant sleeve 9 that a material is emery, the surface contact of described wear-resistant sleeve 9 and step breach 7.
Described dust cover 4 includes the glue be connected with annular groove 8 relative to one end of annular groove 8 position.The sealing effect between dust cover 4 and annular groove 8 can be improved by glue.
Described dust cover 4 includes the region 10 of a storage jump ring 6 relative to one end of annular groove 8 position, can prevent jump ring 6 from exceeding the distance of inner ring 1 and outer ring 2 axial vane surface like this.
The above is only preferred implementation of the present utility model; should be understood 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.
