Abstract
The invention discloses a double-row angular contact bearing with different bearing capacities, which comprises two groups of steel ball groups, two retainers and two bearing inner rings and is characterized by also comprising an outer ring with an integral structure, wherein one group of steel ball groups are arranged between one side of the outer ring and one bearing inner ring and are retained by one retainer, and the other group of steel ball groups are arranged between the other side of the outer ring and the other bearing inner ring and are retained by the other retainer. The invention adopts integral installation, the outer ring is an integral body, the precision is only influenced by the precision, the product precision is high, the product is provided with preload, the cost can be reduced, and the space is saved.
Description
Technical Field
The invention relates to the technical field of bearings, in particular to a double-row angular contact bearing with different bearing capacities.
Background
The traditional double-row angular contact bearing adopts the same steel ball group, and the axial bearing capacity of two sides is the same. At present, referring to fig. 1, the double-row angular contact bearings with different bearing capacities are shown, wherein the double rows of the double-row angular contact bearings respectively adopt steel ball groups 3 and 5 with different diameters, the steel ball group 3 is kept between an inner ring 1 and an outer ring 8 of one row of bearings through a retainer 2, the steel ball group 5 is kept between an inner ring 7 and an outer ring 9 of the other row of bearings through a retainer 6, and the steel ball groups 3 and 5 with different diameters can keep two sides capable of bearing different axial forces and can meet the application conditions with different axial bearing capacity requirements. However, the scheme of the current mature application of the application working conditions with different requirements on the axial bearing capacity is that the outer rings 7 and 9 of two angular contact bearings with different specifications are connected and oppositely installed by adding the sleeve 10, the structure cost is high, and the precision is influenced by the precision tolerance of three parts.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a double-row angular contact bearing with different bearing carrying capacities to improve the precision of the product and reduce the cost, aiming at the above technical problems of the existing double-row angular contact bearing with different bearing carrying capacities.
The technical problem to be solved by the invention can be realized by the following technical scheme:
a double-row angular contact bearing with different bearing capacities comprises two groups of steel ball groups, two retainers and two bearing inner rings and is characterized by further comprising an outer ring of an integral structure, wherein one group of steel ball groups are arranged between one side of the outer ring and one bearing inner ring and are retained by one retainer, and the other group of steel ball groups are arranged between the other side of the outer ring and the other bearing inner ring and are retained by the other retainer.
In a preferred embodiment of the invention, the bottom surface of the outer ring of the integral structure, which is positioned between the two groups of steel balls, is an inclined surface.
Due to the adoption of the technical scheme, the invention adopts integral installation, the outer ring is a whole, the precision is only influenced by the precision, the product precision is high, the product is provided with preload, the cost can be reduced, and the space is saved.
Drawings
Fig. 1 is a schematic structural view of a conventional double-row angular contact bearing with different bearing carrying capacities.
Fig. 2 is a schematic view of the double row angular contact bearing structure with different bearing load capacity of the present invention.
Detailed Description
The invention is further described below in conjunction with the appended drawings and detailed description.
Referring to fig. 2, a double row angular contact bearing with different bearing capacities is shown, comprising two sets of steel ball sets 3, 5, two cages 2, 6 and two inner bearing rings 1, 7.
The invention is characterized in that: the bearing outer ring is an outer ring 4 of an integral structure, wherein one group of steel ball groups 3 is arranged between one side 4a of the outer ring 4 and one bearing inner ring 1 and is held by one retainer 2, and the other group of steel ball groups 5 is arranged between the other side 4b of the outer ring 4 and the other bearing inner ring 7 and is held by the other retainer 6. Therefore, the precision of the double-row angular contact bearing with different bearing capacities is only influenced by the precision, the product precision is high, the double-row angular contact bearing with the different bearing capacities is provided with preload, the cost can be reduced, and the space is saved
The bottom surface 4c of the outer ring 4 of the whole structure, which is positioned between the two groups of steel ball groups 3 and 5, is an inclined surface, so that the strength of the outer ring 4 is further enhanced.
Claims (2)
