Description

Technical Field

[0001] This utility model relates to the field of retaining rings, and more specifically, to retaining rings for holes with a beveled cross-section. Background Technology

[0002] A retaining ring for a bore is a standard component. Its function is to be fitted into a rectangular groove within a part. Because it is made of spring steel and has an opening, it can be tightly fitted into a specific position within the groove, serving as an axial positioning element. It is generally used to position bearings.

[0003] The utility model patent with authorization announcement number CN203730501U discloses a retaining ring with a beveled cross-section, including a bearing housing and a bearing installed inside the bearing housing. An annular groove is provided on one side of the bearing inside the bearing housing, and a retaining ring is installed within the annular groove. The inner surface of the retaining ring is flat and abuts against the outer side of the bearing and the inner wall of the annular groove. The outer surface of the retaining ring is beveled, and the middle part of the outer surface of the retaining ring abuts against the outer wall of the annular groove. The upper half of the outer surface of the retaining ring extends from the annular groove, and the lower half of the outer surface of the retaining ring is located within the annular groove, with a gap between it and the outer wall of the annular groove. This utility model has a simple structure and a trapezoidal cross-section. When installed into the groove, the beveled outer surface automatically eliminates dimensional tolerances, ensuring no gap when it engages with the groove, thus eliminating axial clearance and axial movement to a certain extent.

[0004] In the above-disclosed structure, a bearing box is used to connect a retaining ring for assembly and positioning. However, the retaining ring lacks a ramp, which prevents it from avoiding movement during retraction, making installation difficult. Furthermore, if the notch is set too large, it can easily reduce the connection length and cause insufficient stability, which needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a retaining ring with a beveled cross-section for holes. By setting an end face notch and a slope on the retaining ring body, an elastically bending opening can be formed, which is conducive to alignment and installation after avoidance, and also ensures sufficient connection length, making it highly adaptable. Furthermore, the annular guide groove and through hole are set to guide the flow on the surface, ensuring synchronous lubrication on both sides, improving the use effect, and facilitating positioning and use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A retaining ring with a beveled cross-section includes a retaining ring body. One side of the retaining ring body has an end face notch. Adjustment holes are symmetrically distributed on both sides of the outer surface of the retaining ring body. Both sides of the end face notch have slopes, and one end of each slope has a combined notch located at one end of the slope. A thickened plate is fixedly connected to the other side of the retaining ring body. Both ends of the thickened plate have transition edges that smoothly connect to both sides of the outer surface of the retaining ring body. One side surface of the retaining ring body has an annular guide groove, and the interior of the annular guide groove has a through hole that penetrates the other side surface of the retaining ring body.

[0008] Furthermore, the end face notch and the thickened piece are located on the outer surface of the retaining ring body and are distributed on both sides relative to the center point.

[0009] Furthermore, the slope has an inclination angle of 30 to 40 degrees, and its length is 1.5 times the width of the cross-section of the retaining ring body.

[0010] Furthermore, the adjustment holes are located on one side of the slope, and the spacing is not less than twice the diameter of the adjustment holes. By distributing end face notches and thickened plates on both sides, sufficient strength and stability can be ensured, and elastic deformation can be used for alignment and installation, which is convenient and stable.

[0011] Furthermore, the depth of the annular guide groove is one-third of the thickness of the retaining ring body.

[0012] Furthermore, the length of the annular guide groove is three-quarters of the diameter of the baffle body, and the distance from the end to the far end face notch is not less than twice the width of the end face notch.

[0013] Furthermore, the diameter of the through hole is half the width of the annular guide groove, and they are evenly distributed at equal angles on both sides of the retaining ring body. By setting the annular guide groove and the through hole, the lubricating oil on the same side can be guided to the other side, thereby lubricating from multiple points, ensuring the effect of use, and facilitating positioning and use.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution sets an end face notch and slope on the retaining ring body to form an elastically bent opening, which is conducive to alignment and installation after avoidance, and also ensures sufficient connection length. It has high adaptability. In addition, it sets an annular guide groove and a through hole to guide the flow on the surface, ensure synchronous lubrication on both sides, improve the use effect, and facilitate positioning and use.

[0016] (2) By distributing end face notches and thickened plates on both sides, sufficient strength and stability can be guaranteed, and elastic deformation can be used for alignment and installation, which is convenient and stable.

[0017] (3) By setting an annular guide groove and a through hole, the lubricating oil on the same side can be guided to the other side, thereby lubricating from multiple points, ensuring the effect of use, and facilitating positioning and use. Attached Figure Description
