Description

Technical Field

[0001] The invention relates to the technical field of retaining rings, in particular to an inclined surface locking shallow groove type elastic retaining ring. Background Art

[0002] In daily life, we typically use shaft and hole circlips to prevent axial movement of mating parts on shaft or hole surfaces. The shaft and hole circlips we often purchase are typically thin, with shallow grooves, which can easily cause them to fall off under high-speed rotation. The shaft and hole circlips defined in the national standard manual are thicker and have deeper grooves than the circlips we use daily. While national standard parts certainly offer greater rigidity and reliability, preventing circlip fallout, these high-standard shaft or hole circlips also have certain drawbacks. For example, the national standard circlip groove is deeper, and when used on thinner-walled shafts, machining a deep groove can reduce the shaft's strength and rigidity, potentially making it more susceptible to breakage. Summary of the Invention

[0003] The purpose of the present invention is to provide a bevel-locking shallow-groove elastic retaining ring to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides a bevel locking shallow groove elastic retaining ring, which includes a base, an elastic retaining ring for a hole and an elastic retaining ring for a shaft. The elastic retaining ring for the shaft is arranged on the periphery of the base, and the elastic retaining ring for the hole is arranged inside the base. A matching piece 1 is also provided inside the base, and the matching piece 1 is connected to the elastic retaining ring for the hole. A matching piece 2 is also provided outside the base, and the matching piece 2 is connected to the elastic retaining ring for the shaft.

[0005] Preferably, the hole elastic retaining ring is configured as an annular structure, and an opening 1 is provided on it.

[0006] Preferably, at least one notch 1 is provided on the outer surface of the hole elastic retaining ring, and the cross section of the notch 1 is set to be an arc-shaped structure.

[0007] Preferably, an inner bevel is provided on the inner side of the hole elastic retaining ring.

[0008] Preferably, the shaft elastic retaining ring is configured as an annular structure, and is provided with a second opening.

[0009] Preferably, at least one notch 2 is provided on the inner surface of the shaft elastic retaining ring, and the cross section of the notch 2 is arranged to be an arc-shaped structure.

[0010] Preferably, the outer side of the shaft elastic retaining ring is provided with an external bevel.

[0011] Preferably, an outer side of the first fitting is provided with an outer annular chamfer, and the outer annular chamfer is matched with the inscribed bevel.

[0022] Example See also Figures 1-6 The present invention provides a bevel-locking shallow groove elastic circlip, comprising a base 1, an elastic circlip for a hole 2, and an elastic circlip for a shaft 3. The elastic circlip for the shaft 3 is arranged on the periphery of the base 1, and the elastic circlip for the hole 2 is arranged inside the base 1. A matching piece 1 4 is further provided inside the base 1, and the matching piece 1 4 is connected to the elastic circlip for the hole 2. A matching piece 2 5 is further provided outside the base 1, and the matching piece 2 5 is connected to the elastic circlip for the shaft 3. A placement groove 11 and a placement groove 2 12 are respectively provided on the inner and outer sides of the base 1 for placing the elastic circlip for the hole 2 and the elastic circlip for the shaft 3. The processing depth of the placement groove 11 and the placement groove 2 12 can be less than 0.2 mm, which is suitable for use in various situations.

[0023] The hole elastic circlip 2 is set as an annular structure, and is provided with an opening 21. The outer surface of the hole elastic circlip 2 is provided with at least one notch 22. In this embodiment, two notches 22 are provided, as shown below. Figure 3 As shown, the cross section of the notch 1 22 is arranged as an arc structure, which facilitates the removal of the hole elastic circlip 2. The inner side of the hole elastic circlip 2 is provided with an inscribed inclined surface 23.

[0024] The shaft circlip 3 is provided with an annular structure and has an opening 2 31. The inner surface of the shaft circlip 3 is provided with at least one notch 2 32. In this embodiment, two notches 2 32 are provided, as shown below. Figure 4 As shown, the cross section of the notch 2 32 is arranged as an arc structure, which is convenient for removing the shaft elastic circlip 3. The outer side of the shaft elastic circlip 3 is provided with an external bevel 33.

[0025] In this embodiment, the spring retaining ring for the shaft and the spring retaining ring for the hole are both made of spring steel. In actual applications, they can also be made of other steel materials, which can be selected according to specific usage requirements. The number of notch 1 22 and notch 2 32 can also be selected according to the specific sizes of the spring retaining ring for the shaft and the spring retaining ring for the hole.

[0026] By providing an inscribed bevel 23 on the inner circumferential surface of the hole circlip 2, by providing an circumscribed bevel 33 on the outer circumferential surface of the shaft circlip 3, and correspondingly providing an outer annular chamfer 41 and an inner annular chamfer 51 on the mating piece 1 4 and the mating piece 2 5, the force-bearing surface is converted into an annular bevel, and the pressure on the bevel is decomposed into radial force and axial force. The radial force causes the shaft circlip 3 or the hole circlip 2 to tightly and firmly position itself with the shallow groove on the shaft surface or the hole surface, and the axial force causes the positioned mating piece 1 4 or the mating piece 2 5 to be reliably positioned along the axial direction.

[0027] Both the first fitting (4) and the hole circlip (2), as well as the second fitting (5) and the shaft circlip (3), utilize a bevel locking method. The outer side of the first fitting (4) features an outer annular chamfer (41), which aligns with the inner bevel (23) and has the same machining angle. The inner side of the second fitting (5) features an inner annular chamfer (51), which aligns with the outer bevel (33) and has the same machining angle. The first and second fittings (4, 5) can be configured in a variety of configurations, including stepped shafts, gears, and sleeves.

[0028] Therefore, the present invention adopts the above-mentioned bevel locking shallow groove elastic retaining ring, which has reasonable force, and the elastic retaining ring for the hole and the elastic retaining ring for the shaft are not easy to fall off, and will not fall off during high-speed rotation; assembly and disassembly are easy, and can be easily completed with tools or bare hands; there are almost no requirements for the wall thickness of the installation shaft, and a shaft with a wall thickness of two or three millimeters can also meet the use requirements; in addition to installation in a shallow groove, it can also be installed and used in a grooveless state.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
