Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the tapered roller bearing with the structure of the copper retainer 5 comprises an inner ring 1, wherein two sides of the outer wall of the inner ring 1 are respectively provided with a large flange 2 and a small flange 3, the outer wall of the inner ring 1 is sleeved with an outer ring 4, a retainer 5 is arranged between the inner ring 1 and the outer ring 4, the retainer 5 is integrally formed, the retainer 5 is positioned between the large flange 2 and the small flange 3, a plurality of pockets 8 are formed in the retainer 5, rolling bodies 6 are inserted into the pockets 8, and the rolling bodies 6 are positioned between the inner ring 1 and the outer ring 4.

The retainer 5 is provided with a plurality of equidistant holes, which are called pockets 8, the rolling bodies 6 are positioned in the pockets 8, the small flanges 3 and the large flanges 2 guide the rolling bodies 6, so that the bearing can run more stably, the bearing is different from the post retainer 5, the post retainer 5 adopts a split manufacturing and assembling structure, then is welded and formed, the retainer 5 is of an integral structure, the welding is easy to generate stress deformation between connecting pieces, and the welding part is required to be subjected to gap flaw detection, so that the mechanical property of the retainer 5 is ensured, the integral structure is more stable, deformation is not easy to occur, and the later use can be more stable.

Specifically, the holder 5 is made of metallic copper.

The arrangement of the lock point 7 facilitates installation.

Specifically, the pocket 8 is assembled using the artificial chisel lock point 7.

The pocket 8 of the copper retainer 5 is assembled by adopting a manual locking point 7, and the assembly is relatively convenient compared with the assembly of the punching retainer 5 and the strut retainer 5.

Specifically, the outer wall of the inner ring 1 and the inner wall of the outer ring 4 are inclined surfaces.

As shown in the attached drawing, the outer wall of the inner ring 1 and the inner wall of the outer ring 4 are inclined surfaces, the inclination angles are consistent, and the rolling bodies 6 can be wrapped by combining the large flange 2 and the small flange 3 for use.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
