Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bearing retainer, especially a bearing nylon retainer. BACKGROUND

[0002] The retainer is an important component in the bearing, which separates the rollers evenly to prevent them from contacting each other, reduces the friction and wear, and guides the rolling elements to move on the correct track during the operation of the bearing, ensuring the uniform distribution of the rolling elements and reducing the stress concentration. According to the different actual operation conditions of the bearing, when assembled on the eccentric shaft, the impact force and centrifugal force are relatively large during the rotation of the inner ring of the bearing, and the force is transmitted to the inner ring and the rollers through the mandrel. The rollers will impact the pockets of the retainer. The pockets of the retainer of the prior art will be damaged quickly, resulting in the failure of the bearing and affecting the service life of the bearing. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides a bearing nylon retainer which can reduce the impact and has higher stability.

[0004] To achieve the above-mentioned purpose, the utility model provides a bearing nylon retainer which comprises a ring-shaped frame body, a plurality of circumferentially spaced pockets are arranged on the frame body, the frame body comprises a plurality of circumferentially spaced connecting parts, the connecting parts extend axially, the pockets are formed by the spacing between adjacent connecting parts, and each pocket comprises two openings which are located on the radial extension lines of the center of the frame body.

[0005] The advantages of the above technical scheme are as follows: a plurality of circumferentially spaced connecting parts are arranged on the ring-shaped frame body, the connecting parts extend circumferentially, the pockets are formed by the spacing between the connecting parts, two openings which are located on the radial extension lines of the center of the frame body are arranged on the pockets, the frame body can be placed at the spacing of the axial direction of the bearing raceway, the rollers are guided by the pockets, and the impact force and centrifugal force can be directly transmitted to the outer ring through the rollers during the operation, so that the impact can be reduced and the stability is higher.

[0006] The utility model can be further provided as follows: the pockets are columnar and comprise an abutting inner wall, the two ends of the abutting inner wall extend along the arc and are arranged in a half-ring shape, and the two sides of the abutting inner wall extend along the radial straight line, and the abutting inner wall can form a linear contact with the rollers.

[0007] By further setting, the pocket is set as a columnar shape and comprises an abutting inner wall, both ends of the abutting inner wall extend along an arc and present a half ring shape, and the two sides of the abutting inner wall extend along a straight line, so that the abutting inner wall of the pocket can form linear contact with the roller, and further avoid that the roller is impacted in the radial direction and the impact is conducted to the retainer, so that the stability of the retainer is ensured.

[0008] The utility model discloses further set up: the connecting portion of pocket two sides all is provided with extension, the extension be corresponding with the arc shape of abutting inner wall setting, and the extension of pocket two sides is opposite and extends and forms lock mouth.

[0009] By further setting, the extension is set as an arc shape on the connecting portion of the two sides of the pocket, and the extensions of the two sides of the pocket are opposite and extend to form a lock mouth, so that the situation of the roller being taken out is avoided.

[0010] The utility model discloses further set up: the extension is gradually small in thickness to its extension direction setting.

[0011] By further setting, the extension is gradually small in thickness to its extension direction, so that the connecting strength of the extension is ensured. DRAWINGS

[0016] The utility model discloses a kind of bearing nylon retainer's implementation, as shown in Figs. 1-3 It is shown in the figure: including annularly arranged frame body 1, the frame body 1 is provided with several circumferentially spaced pockets 11, the frame body 1 includes several circumferentially spaced connecting portions 12, the connecting portion 12 is axially extended and set, the pocket 11 is formed by the interval between adjacent connecting portions 12, and the pocket 11 includes two openings 111, which are both corresponding to the radial extension line of the center of the frame.

[0017] The pocket 11 is cylindrically arranged and comprises an abutting inner wall 112, two ends of the abutting inner wall 112 are arranged in an arc shape and in a half ring shape, and two sides of the abutting inner wall 112 are arranged in a radial straight line, and the abutting inner wall 112 can form a line contact with the roller.

[0018] The connecting part 12 on the two sides of the pocket 11 is provided with an extension part 13, the extension part 13 is arranged in an arc shape corresponding to the abutting inner wall 112, and the extension parts 13 on the two sides of the pocket 11 extend towards each other to form a lock opening 14.

[0019] The extension part 13 is arranged in a gradually smaller thickness towards the extension direction.

[0020] The above examples are only one of the preferred specific examples of the present application, and the usual changes and replacements made by those skilled in the art within the technical scheme of the present application are all included in the protection scope of the present application.
