Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a nylon bearing retainer. Background Art
[0002] The main function of the bearing nylon retainer is to evenly isolate the rolling elements. It is formed by thermoplastic molding. In the traditional structure, except for the pocket and the lock claw, the bearing nylon retainer is an integral structure. After thermoplastic molding, the wall thickness of the retainer is uneven, resulting in large deformation, which affects the use of the bearing. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a nylon bearing retainer with uniform wall thickness, which reduces the influence of thermoplastic deformation on the bearing product.
[0004] The utility model achieves the above technical purpose through the following technical means.
[0005] A bearing nylon retainer comprises a retainer main frame, on which a pocket hole and a locking claw are provided, a circle of grooves are provided at the bottom of the retainer main frame, the inner and outer sides of the grooves serve as the inner and outer sides of the retainer respectively, the pocket hole and the groove serve as the retainer end face, and the locking claw and the groove serve as the pocket hole connecting ribs.
[0006] In the above technical solution, the thickness of the pocket connection rib, the thickness of the end face of the retainer, the wall thickness of the inner side of the retainer and the wall thickness of the outer side of the retainer are all between 1 and 2 mm.
[0007] In the above technical solution, the wall thickness of the inner side of the retainer and the wall thickness of the outer side of the retainer are the same.
[0008] In the above technical solution, the thickness of the pocket connecting ribs ranges from 1.4 to 2.0 mm.
[0009] In the above technical solution, the thickness of the end face of the retainer ranges from 1.0 to 1.5 mm.
[0010] In the above technical solution, the wall thickness of the inner / outer side of the retainer ranges from 1.0 to 1.5 mm.
[0011] The beneficial effects of the utility model are as follows: the bearing nylon retainer of the utility model is processed with a groove at the bottom of the traditional structure. After the groove is cut, the wall thickness of each part of the retainer is uniform, so that the retainer has little deformation and stable quality after thermoplastic molding; because the retainer is provided with a bottom groove, less material is used, saving economic costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.
[0013] Figure 1 This is a schematic diagram of the structure of the bearing nylon retainer of the utility model;

[0015] Among them, the reference numerals in the figure are:
[0016] 1- pocket hole, 2- locking claw, 3- bottom groove, S0- pocket hole connecting rib thickness, S- retainer end face thickness, S1- retainer inner wall thickness, S2- retainer outer wall thickness. DETAILED DESCRIPTION
[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0018] See also Figure 1 , 2 The utility model provides a bearing nylon retainer, in which a circle of grooves is provided at the bottom of the conventional bearing nylon retainer, forming a bottom groove 3. The conventional bearing nylon retainer is provided with a pocket hole 1 and a locking claw 2 on the retainer main frame.
[0019] Continue to see Figure 1 , 2 After slotting, the inner and outer sides of the groove 3 are the inner and outer sides of the retainer, the pocket 1 and the groove serve as the end face of the retainer, and the locking claw 2 and the groove serve as the pocket connecting rib.
[0020] The dimensional parameters of each part of the bearing nylon retainer: the thickness of the pocket connection rib S0, the thickness of the retainer end face S, the inner wall thickness S1 of the retainer and the outer wall thickness S2 of the retainer are basically the same, and the values are all between 1 and 2 mm; specifically, the value range of the pocket connection rib thickness S0 is 1.4 to 2.0 mm, the value range of the retainer end face thickness S is 1.0 to 1.5 mm, the inner wall thickness S1 of the retainer is the same as the outer wall thickness S2 of the retainer, and the value can be within 1.0 to 1.5 mm. By setting the above parameters, while ensuring the strength of the bearing nylon retainer, it can be ensured that the wall thickness of each part of the bearing nylon retainer is basically the same, reducing the deformation problem after thermoplasticization, and after multiple batches of production, the quality of the bearing nylon retainer is stable.
[0021] The utility model provides a bearing nylon retainer, the groove processing is convenient and quick, and can be formed in one time using the corresponding mold. After the groove is opened, the wall thickness of each part is uniform, and the deformation after thermoplastic molding is small, which greatly improves the quality stability of the retainer, uses less materials, and reduces economic costs.
[0022] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
