Description

Technical Field

[0001] This utility model relates to the field of ring technology, specifically to a ring with an eccentric outer diameter stop groove. Background Technology

[0002] Bearing rings are one of the core components of rolling bearings. They are annular parts with one or more raceways, and are divided into inner rings and outer rings. They are mainly used to support rolling elements and transmit loads. Bearing rings are annular structural components with raceways in rolling bearings. Their core functions include supporting rolling elements, guiding the movement trajectory of rolling elements through raceways, ensuring smooth operation of the bearing, bearing radial, axial, or combined loads from the shaft or bearing housing, and evenly distributing the force to the rolling elements. They also provide positioning; the inner ring fits tightly with the shaft and rotates synchronously, while the outer ring is fixed in the bearing housing, together maintaining the alignment of the mechanical system.

[0003] While existing retaining rings meet users' needs to a certain extent, they still have certain shortcomings during use. Specific problems include insufficient positioning accuracy and stability; most retaining rings lack specialized positioning structures or have poor adaptability to these structures, leading to displacement after assembly and causing shaft transmission deviations; improper lubrication management, resulting in excessive lubrication buildup inside the retaining ring, significantly increasing surface friction resistance, exacerbating wear, and consuming more power; and poor wear resistance, as the retaining ring is in long-term contact and friction with shafts, sleeves, and other components. Traditional retaining rings lack effective wear protection on their inner walls, easily leading to shortened service life due to wear, increasing equipment maintenance costs and replacement frequency, and failing to meet the requirements of high-precision, long-life mechanical transmission. Therefore, this invention designs an eccentrically oriented retaining ring with an outer diameter to solve the above problems. Utility Model Content

[0004] This utility model provides an eccentric retaining groove ring with an outer diameter, which can effectively solve the problems mentioned in the background art, such as insufficient positioning accuracy and stability, lack of a dedicated positioning structure or poor adaptability of the positioning structure, easy displacement after assembly, resulting in shaft transmission deviation, and improper lubrication management, which can easily lead to excessive accumulation of lubricant inside the ring, resulting in a significant increase in the frictional resistance of the parts surface, which not only aggravates wear but also consumes more power. At the same time, the wear resistance is poor. The ring is in long-term contact and friction with components such as shafts and sleeves. The inner wall of traditional rings lacks effective wear protection, which can easily lead to a shortened service life due to wear, increasing equipment maintenance costs and replacement frequency, and making it difficult to meet the requirements of high precision and long service life mechanical transmission.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an eccentric stop groove collar with an outer diameter, comprising a collar housing, a stop groove being provided on the outer side of the collar housing, mounting grooves being provided at both ends of the inner side of the collar housing, a limiting groove being provided at the bottom end of the mounting groove, an eccentric groove being provided at the end of the limiting groove, and a placement groove being provided between the two eccentric grooves.

[0006] An eccentric stop groove sleeve with an outer diameter, preferably wherein the inner wall of the stop groove is coated with an elastic coating.

[0007] An eccentric stop groove ring with an outer diameter, preferably wherein the inner wall of the groove is coated with a wear-resistant layer.

[0008] An eccentric stop groove sleeve with an outer diameter, preferably wherein the end face of the eccentric groove is provided with a flow groove.

[0009] An eccentric stop groove sleeve with an outer diameter, preferably, has an eccentric groove of 0.35mm and an inclined angle at the end of the limiting groove.

[0010] An eccentric stop groove sleeve with an outer diameter, preferably wherein the elastic coating is a polytetrafluoroethylene elastic coating and the thickness of the elastic coating is 0.1 mm.

[0011] An eccentric stop groove ring with an outer diameter, preferably wherein the wear-resistant layer is made of graphene composite material and the thickness of the wear-resistant layer is 0.15 mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The structure of this utility model is scientific and reasonable, and it is safe and convenient to use: The stop groove opened on the outer side of the ring housing can realize the precise positioning of the ring and the external parts, and the elastic coating sprayed on the inner wall of the stop groove can enhance the fit and buffering during positioning, and avoid displacement after assembly. The inclined angle opened at the end of the limiting groove facilitates the placement of the sleeve, and the eccentric groove is designed with an eccentricity of 0.35mm, which can accurately realize the eccentric rotation of the shaft, effectively ensure the consistency of eccentric rotation, and reduce transmission vibration and noise. The flow channels on the end face of the eccentric groove adopt a staggered distribution design. When the lubricant enters the inside of the ring housing, the excess lubricant can flow in from one end of the flow channel and flow out from the other end of the flow channel through the staggered distribution channels. This avoids excessive accumulation of lubricant on the surface of the parts, thereby significantly reducing the frictional resistance between the parts, reducing power loss, and preventing abnormal wear caused by excessive lubricant. The wear-resistant layer sprayed on the inner wall of the placement tank has excellent wear-resistant properties, which can effectively resist the frictional loss caused by long-term contact between the ring and components such as shafts and sleeves, greatly improve the wear resistance of the ring, extend its service life, and reduce the frequency of equipment maintenance and replacement costs.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: an eccentric stop groove collar with an outer diameter, including a collar housing 1, a stop groove 2 on the outer side of the collar housing 1, an elastic coating 3 sprayed on the inner wall of the stop groove 2, mounting grooves 4 at both ends inside the collar housing 1, a limiting groove 5 at the bottom end of the mounting groove 4, an eccentric groove 6 at the end of the limiting groove 5, a placement groove 7 between the two eccentric grooves 6, a wear-resistant layer 8 sprayed on the inner wall of the placement groove 7, and a flow groove 9 at the end face of the eccentric groove 6.

[0017] The eccentric groove 6 is eccentric by 0.35mm, and the end of the limiting groove 5 is provided with an inclined angle, which facilitates the placement of the sleeve and the positioning of the ring. At the same time, it can realize the eccentric rotation of the shaft and ensure the consistency of eccentricity.

[0018] The elastic coating 3 is made of polytetrafluoroethylene and has a thickness of 0.1 mm.

[0019] The wear-resistant layer 8 is made of graphene composite material and has a thickness of 0.15mm.

[0020] Multiple flow channels 9 at both ends of the placement groove 7 are staggered. During the use of the ring housing 1, when the lubricant enters the inside of the ring housing 1, and when the lubricant flows in from the flow channel 9 at one end of the ring housing 1, the excess lubricant can flow out from the other end through the multiple staggered flow channels 9, thus avoiding the problem that excessive gear oil will cause a significant increase in the frictional resistance between the surfaces of the parts.

[0021] First, assemble the outer sleeve into the mounting groove 4 of the ring housing 1. Use the tilt angle at the end of the limiting groove 5 to guide the sleeve into the mounting groove 4 smoothly. At the same time, the stop groove 2 on the outside of the ring housing 1 cooperates with the external equipment structure to achieve the initial positioning of the ring. The elastic coating 3 on the inner wall of the stop groove 2 will fit tightly with the external structure during the assembly process, further enhancing the positioning stability and preventing the ring from shifting. The sleeve is placed in the placement groove 7 inside the ring housing 1. At this time, the 0.35mm eccentricity of the eccentric groove 6 can enable the sleeve to achieve the preset eccentric rotation requirement. The limiting groove 5 plays a limiting role on the end of the sleeve, preventing the sleeve from axially moving during rotation and ensuring the accuracy of the fit between the sleeve and the ring. When the ring and sleeve are assembled and put into use, an appropriate amount of lubricant is injected into the ring housing 1. The lubricant will fill the contact gap between the shaft and the placement groove 7, and play a lubricating role. Excess lubricant will flow into the flow groove 6 on the end face of the eccentric groove 6. Since the flow groove 9 adopts a staggered distribution design, the excess lubricant will flow from one end of the ring to the other end along the flow groove 9 channel, and finally be discharged from the outside of the ring housing, avoiding the accumulation of lubricant. During the continuous eccentric rotation of the ring, the wear-resistant layer 8 on the inner wall of the placement groove 7 will directly contact the balls, resisting the wear caused by friction between the two and reducing the wear on the inner wall of the placement groove 7. At the same time, the elastic coating 3 and the wear-resistant layer 8 work together to ensure that the ring can maintain stable structural performance and transmission accuracy during long-term use, thereby improving the service life of the sleeve.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
