Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts technology, and specifically relates to a retaining ring assembly. Background Technology

[0002] Cage rings, as a basic mechanical limiting element, are widely used in various mechanical equipment. They are mainly used to achieve axial positioning or limiting of components. In complex and dynamic working conditions such as automotive transmission systems, traditional metal cage rings can usually only provide rigid axial limiting functions. This design exposes many shortcomings when facing high-frequency vibration, impact and temperature changes.

[0003] Traditional metal retaining rings have a rigid contact with the mounting groove or assembly parts. This metal-to-metal fit has almost no vibration damping capability. High-frequency vibrations generated by the automotive transmission system will be directly transmitted through the retaining ring, resulting in harsh noise.

[0004] Meanwhile, under alternating thermal expansion and contraction conditions, minute gaps develop between the metal retaining ring and the mating components. These gaps can cause the retaining ring to loosen under vibration and impact, reducing the stability and precision of the assembly. Due to the lack of elastic cushioning, the rigid metal retaining ring can cause wear or scratches on the contacting assembly components under long-term vibration and friction, affecting the service life of the relevant components.

[0005] Therefore, the existing retaining rings have a relatively simple function and cannot simultaneously meet multiple requirements such as limiting, noise reduction, vibration reduction and wear protection, making it difficult to meet the requirements of the modern automotive industry for high smoothness and high reliability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0023] like Figures 1-5 The illustration shows an embodiment of the present invention, which discloses a retaining ring assembly, including a metal ring body 1, a wear-resistant component 2, and a noise-reducing component 3. The wear-resistant component 2 is annular and disposed on the inner wall of the metal ring body 1, and the noise-reducing component 3 is annular and disposed on the outer wall of the metal ring body 1. Both the wear-resistant component 2 and the noise-reducing component 3 are made of elastic material and are designed to fit tightly with the assembly components.

[0024] In this embodiment, the retaining ring assembly utilizes the wear-resistant component 2 and the noise reduction component 3 on the metal ring body 1 to form an elastic interference fit with the assembly parts. This effectively solves the problems of high-frequency vibration, high noise, easy wear, and loosening due to gaps caused by thermal expansion and contraction in existing retaining rings caused by rigid contact. It achieves vibration reduction and noise reduction, protects the contact parts from wear, and enhances the stability of the limit position.

[0025] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the wear-resistant component 2 includes two wear-resistant rings 21, which are respectively arranged circumferentially along the metal ring body 1 and symmetrically distributed on both sides of the inner wall of the metal ring body 1. Meanwhile, the inner walls of the two wear-resistant rings 21 are respectively provided with guide grooves 22 for the entry of lubricating medium, facilitating the application of the lubricating medium by the operator. In this embodiment, the cross-sectional shape of the guide groove 22 can be V-shaped or U-shaped, so that the guide groove 22 provides space for the application and containment of the lubricating medium.

[0026] In this embodiment, the wear-resistant ring 21 is made of wear-resistant silicone material to improve the wear-resistant protection effect. At the same time, the wear-resistant ring 21 can also increase the friction with the assembled parts and prevent the retaining ring from shifting circumferentially or axially. In addition, each wear-resistant ring 21 is provided with multiple guide grooves 22, and the multiple guide grooves 22 are arranged at equal intervals along the circumference of the wear-resistant ring 21, and the inclination direction of the guide grooves 22 on two wear-resistant rings 21 is opposite.

[0027] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 As shown, a receiving ring 4 is integrally formed along the circumference of the middle position of the inner wall of the metal ring 1, so that mounting grooves 5 are formed on both sides of the inner wall of the metal ring 1 on the receiving ring 4, and two wear-resistant rings 21 are respectively detachably embedded in the corresponding mounting grooves 5. At the same time, the thickness of the wear-resistant ring 21 is the same as the thickness of the receiving ring 4. In this embodiment, the inner wall of the wear-resistant ring 21 is flush with the inner wall of the receiving ring 4, and the end face of the wear-resistant ring 21 is flush with the end face of the metal ring 1.

[0028] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 As shown, multiple limiting plates 6 are provided on the side of the two wear-resistant rings 21 that are close to each other. The multiple limiting plates 6 are arranged at equal intervals along the circumference of the corresponding wear-resistant rings 21, and the limiting plates 6 are integrally formed and connected to the corresponding wear-resistant rings 21. Multiple limiting holes 7 are provided through the receiving ring 4 along its axial direction, and the two limiting plates 6 provided on the two wear-resistant rings 21 can be inserted into the same limiting hole 7.

[0029] In one embodiment, such as Figure 4 , Figure 5As shown, the outer wall of the metal ring 1 is provided with multiple disassembly ports 8, which are respectively connected to corresponding limiting holes 7. Two locking balls 9 are respectively provided on the inner wall of each limiting hole 7, and each limiting plate 6 is provided with a locking hole 10, with the locking balls 9 able to engage with the corresponding locking hole 10. Simultaneously, the inner wall of each limiting plate 6 is provided with a guide slope 11, so that the limiting plate 6 can smoothly engage with the corresponding limiting hole 7 and undergo elastic deformation, thereby allowing the locking balls 9 to smoothly engage with the locking hole 10.

[0030] In the assembled state, the wear-resistant ring 21 is embedded in the mounting groove 5, and the limiting plate 6 is aligned and inserted into the corresponding limiting hole 7. During insertion, the guide slope 11 of the limiting plate 6 first contacts the locking ball 9 and undergoes elastic bending until the locking hole 10 aligns with the corresponding locking ball 9. The limiting plate 6 then rebounds under its own elastic force, causing the locking ball 9 to engage in the locking hole 10. This design ensures that the wear-resistant ring 21 is firmly locked onto the metal ring body 1. It also allows for easy disassembly by using the disassembly port 8 and tools to pry the limiting plate 6 apart from the locking ball 9 when replacement is needed.

[0031] In one embodiment, such as Figure 1 , Figure 5 As shown, the noise reduction component 3 includes a first noise reduction ring 31 and two second noise reduction rings 32, which are respectively sleeved on the outer wall of the metal ring body 1. The first noise reduction ring 31 is located at the middle of the outer wall of the metal ring body 1, and the two second noise reduction rings 32 are symmetrically distributed on both sides of the first noise reduction ring 31, and the two second noise reduction rings 32 respectively abut against the first noise reduction ring 31.

[0032] In this embodiment, the first noise reduction ring 31 is made of rubber or polyurethane material, and the second noise reduction ring 32 is made of silicone material. The two second noise reduction rings 32 are hollow so that the retaining ring can elastically interfere with the assembly component, thereby strengthening the axial limit.

[0033] In this embodiment, the two second noise reduction rings 32 are fixedly connected to the metal ring body 1, and the first noise reduction ring 31 is detachably connected to the metal ring body 1.

[0034] In one embodiment, such as Figure 1 , Figure 2 As shown, the metal ring 1 is provided with an inclined slot 12 for releasing the elastic stress inside, so that the retaining ring has the ability to deform elastically during installation, thereby enabling the retaining ring to be installed smoothly.

[0035] In this embodiment, when installing the retaining ring assembly, if it is installed by fitting it onto the outside of the assembly component, the metal ring 1 is installed first, and then the first noise-reducing ring 31 is fitted onto the middle of the outer side of the metal ring 1. The elasticity of the first noise-reducing ring 31 tightly hugs the metal ring 1 around the outside of the assembly component. If an internal retaining ring is used, the first noise-reducing ring 31 is first fitted onto the outside of the metal ring 1, and then both ends of the metal ring 1 are pressed towards the center along the inclined seam 12 to insert the metal ring 1 into the internal groove of the assembly component.

[0036] As described above, during the operation of the automotive transmission system, the second noise-reducing ring 32 ensures an elastic interference fit between the retaining ring and the assembled components, strengthening axial restraint and preventing loosening caused by gaps due to thermal expansion and contraction of the components. Simultaneously, the wear-resistant ring 21 increases the friction between the retaining ring and the assembled components, effectively preventing circumferential or axial displacement of the retaining ring under vibration and impact conditions during vehicle operation, ensuring long-term stable assembly accuracy.

[0037] Meanwhile, the guide grooves 22 on the wear-resistant ring 21 facilitate better application of the lubricating medium to the assembled parts. The dual elastic buffer formed by the second noise-reducing ring 32 and the wear-resistant ring 21 attenuates high-frequency vibrations in the automotive transmission system. The combination of the metal ring 1, the second noise-reducing ring 32, and the wear-resistant ring 21 forms a combined soft and hard protective mechanism for the assembled parts, preventing wear and scratches caused by the metal ring 1 to the contacting parts. The first noise-reducing ring 31 also fills the gap between the two second noise-reducing rings 32, preventing the accumulation and retention of impurities in this area.
