The following embodiments and features in the embodiments can be combined with each other without conflict.

[0075] In the related art, the retainer is a fan-shaped segment or a ring member with multiple square holes. Because of the existence of the square holes, the material of the square hole part needs to be dug out during processing, thus causing the problem of low material utilization.

[0076] Therefore, the embodiments of the present application aim to provide a thrust bearing retainer and a processing method, and a radial bearing retainer and a processing method. Two relatively cross-set sawtooth structures are formed on the plate material by cutting the plate material in a sawtooth shape, wherein the sawtooth of one sawtooth structure is located between two sawteeth of the other sawtooth structure. Compared with the solution in the related art, the sawtooth in the present application occupies part of the material corresponding to the square hole that is dug out, thus improving the material utilization of the plate material, i.e., improving the material utilization of the retainer, which is beneficial to reducing the material cost, and two sawtooth structures can be obtained by one cutting, which is beneficial to improving the cutting efficiency.

[0077] The content of the embodiments of the present application will be described in detail below in combination with the accompanying drawings, so that a person of ordinary skill in the art can understand the content of the present application in more detail.

[0078] It should be noted that the first direction X, the second direction Y, and the third direction Z in the present application are three different directions perpendicular to each other in a three-dimensional space.

[0080] Figure 2 Structure diagram after cutting a first plate material in a sawtooth shape provided by an embodiment of the present application; Figure 3A structural diagram of the outer diameter sawtooth structure provided by an embodiment of the present application is shown in FIG. 1. Figure 4 A structural diagram of the inner diameter sawtooth structure provided by an embodiment of the present application is shown in FIG. 2.

[0081] Please refer to Figures 1-4 The present embodiment provides a thrust bearing retainer processing method, which comprises the following steps.

[0082] In step S110, a first plate is provided. The material of the first plate can be selected as required, for example, it can be steel.

[0083] In step S120, a first arc is cut on the first side of the first plate in the first direction.

[0084] For example, as shown in FIG. 1, the first arc 101 is located on the first side of the first plate in the second direction Y. Figure 2

[0085] In step S130, the first plate is cut in a sawtooth manner from one end of the first arc, so that an outer diameter sawtooth structure is formed on the first plate. The outer diameter sawtooth structure comprises a plurality of first sawteeth and a first connecting plate. The plurality of first sawteeth are located on the first connecting plate, and the first sawteeth are trapezoidal.

[0086] For example, the outer diameter sawtooth structure 100 comprises a plurality of first sawteeth 120 and a first connecting plate 110. The distance between two adjacent first sawteeth 120 is greater than 1-2 mm, which is the size of the roller to be installed.

[0090] ​​Exemplarily, the inner diameter sawtooth structure 200 includes a plurality of second sawteeth 220 and second connecting plates 210, and the interval between two adjacent second sawteeth 220 is greater than the size of the roller to be installed by 1-2 mm. The first plate material is simultaneously cut into the outer diameter sawtooth structure 100 and the inner diameter sawtooth structure 200 after the sawtooth cutting, so as to realize the combined blanking of the outer diameter sawtooth structure 100 and the inner diameter sawtooth structure 200. Moreover, since the first sawteeth 120 are located between two adjacent second sawteeth 220, and the second sawteeth 220 are located between two adjacent first sawteeth 120, compared with the scheme in the related art, the first sawteeth 120 and the second sawteeth 220 in the embodiment both occupy part of the material corresponding to the square hole that is dug out (that is, the material in the square hole in the related art is discarded, and part of the material of the square hole constitutes the first sawteeth 120 and the second sawteeth 220 in the present application), so that the material utilization rate of the first plate material is improved, that is, the material utilization rate of the retainer is improved, which is conducive to reducing the material cost, and the entire cutting process can be kept continuous, the operation of transferring the wire cutting wire is saved, and the cutting efficiency is improved.
