Description

Technical Field

[0001] The utility model belongs to the technical field of retaining rings and relates to a retaining ring component. Background Art

[0002] Retaining rings, also known as retaining rings, are mainly divided into retaining rings for holes and retaining rings for shafts. They play the role of axial limit in mechanical engineering and are used to prevent other parts from moving in the axial direction. Existing retaining rings are generally integrated, which are prone to wear and tear during loading and unloading, and in severe cases, they may break, resulting in the need to replace the entire thing. In actual use, the shaft diameter to which it is assembled may be temporarily modified to a backup product due to actual needs, and the attached retaining ring cannot be matched, which affects its assembly efficiency and does not meet the use requirements. Summary of the invention

[0003] The purpose of the utility model is to provide a retaining ring assembly which reduces wear and solves the above problems in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a retaining ring assembly, including a retaining ring body with an axial hole, characterized in that the retaining ring body is provided with an installation unit connected to the axial hole and used to meet the installation of different shaft diameters, and an open groove is opened on the outer peripheral wall of the retaining ring body to connect the axial hole with the outside.

[0005] In the above-mentioned retaining ring assembly, the mounting unit is a mounting ring with an assembly hole, and the mounting ring is connected to the retaining ring body in a sliding fit.

[0006] In the above-mentioned retaining ring assembly, a plurality of snap-in ears connected to the mounting ring and snap-fitted with the retaining ring body are arranged on the outer peripheral wall of the mounting ring, a plurality of snap-in grooves for the corresponding snap-in ears to be installed and communicated with the shaft hole are opened on the end face of the retaining ring body, a contact plate connected to the retaining ring body and in contact with the snap-in ear is arranged on one end of the retaining ring body located at the snap-in groove, and a limit plate slidably matched with the retaining ring body and used to limit the position of the snap-in ear is arranged on the other end of the retaining ring body located at the snap-in groove.

[0007] Compared with the prior art, the retaining ring assembly has the following advantages:

[0008] 1. The retaining ring body is provided with an installation unit connected to the shaft hole and used to meet the installation of different shaft diameters. An opening groove is opened on the outer peripheral wall of the retaining ring body to connect the shaft hole with the outside. The above structure is arranged to facilitate its assembly and ensure replacement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the three-dimensional structure of the retaining ring assembly.

[0010] In the figure, 1, the retaining ring body; 2, the opening groove; 3, the mounting ring; 4, the snap-on ear; 5, the resistance plate; 6, the limit plate. DETAILED DESCRIPTION

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, the retaining ring assembly includes a retaining ring main body 1 with an axial hole, and the retaining ring main body 1 is provided with an installation unit connected to the axial hole and used for installation to meet different axial diameters. An open groove 2 is opened on the outer peripheral wall of the retaining ring main body to connect the axial hole with the outside, and a disassembly block detachably connected to the retaining ring main body 1 can be provided at the open groove 2. The installation unit is a mounting ring 3 with an assembly hole, and the inner diameter of the assembly hole varies according to the equipment model. The mounting ring 3 is connected to the retaining ring main body 1 in a sliding fit, and the height of the mounting ring 3 is less than the height of the retaining ring main body 1.

[0013] To elaborate further, in order to prevent the mounting ring 3 from detaching from the retaining ring body 1 while not affecting the use of the retaining ring body 1, a plurality of snap-in ears 4 connected to it and snap-fitted with the retaining ring body 1 are provided on the outer peripheral wall of the mounting ring 3. The snap-in ears 4 can be arranged in a fan-shaped or semicircular structure, and a plurality of snap-in grooves for the corresponding snap-in ears 4 to be installed and connected to the shaft hole are provided on the end face of the retaining ring body 1. A resistance plate 5 connected to it and in contact with the snap-in ear 4 is provided on one end of the retaining ring body 1 located at the snap-in groove, and a limit plate 6 slidably matched with it and used to limit the position of the snap-in ear 4 is provided on the other end of the retaining ring body 1 located at the snap-in groove. A sliding groove axially recessed inwardly and for slidingly assembling the limit plate 6 is provided on the inner wall of the retaining ring body 1 located at the snap-in groove. A limit shaft connected to it can be provided at the sliding groove, and the position of the limit plate 6 is limited by the limit shaft to prevent the limit plate 6 from detaching from the sliding groove.

[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0015] Although the present invention uses more terms such as retaining ring body 1, opening groove 2, mounting ring 3, clamping ear 4, abutment plate 5, and limit plate 6, it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
