A new energy vehicle transmission self-lubricating bearing ring

Abstract

This utility model discloses a self-lubricating bearing ring for new energy vehicle transmission, including an outer bearing ring. A circulation pipe is snapped into a groove in the outer bearing ring, and the circulation pipe is tightly attached to a first groove, which is formed on a snap-fit ​​block. This utility model utilizes the fact that solid lubricant is typically embedded in the inner bearing ring material. During bearing operation, due to friction and temperature changes, the lubricant in the ring is gradually released to the friction surface. The lubricating film effectively reduces direct metal-to-metal contact, thereby reducing the coefficient of friction and wear rate. The lubricating film can also absorb some heat, helping to control the bearing temperature rise. The three-layer protection of the first, second, and third dustproof rings effectively prevents dust from entering, thus improving the bearing's lubrication efficiency and service life. The circulation pipe contains a heat-absorbing solution, which can significantly improve the heat dissipation capacity of the outer bearing ring, slowing down bearing material fatigue and performance degradation.

Description

Technical Field

[0001] This utility model relates to the field of bearing ring technology, and in particular to a self-lubricating bearing ring for transmission in new energy vehicles. Background Technology

[0002] Self-lubricating bearings have built-in solid lubricants (such as PTFE, graphite, molybdenum disulfide, etc.) in the bearing rings, which can continuously release lubricating components during operation, eliminating the need for regular lubrication with oil or grease. They have low maintenance costs because they do not require frequent lubrication, reducing downtime for maintenance and labor costs, and are particularly suitable for transmission parts that are difficult to access or maintain. Self-lubricating bearings can maintain good performance under conditions such as high temperature, low temperature, high humidity, dust, and corrosive environments, and are not prone to seizing or wear due to lubrication failure.

[0003] However, the self-lubricating bearing rings commonly used in transmissions on the market have some obvious defects: First, the bearings are not equipped with heat dissipation devices, which leads to the accumulation of heat that cannot be dissipated in time, and long-term operation will accelerate the fatigue and performance degradation of the bearing materials; on the other hand, the lack of dust prevention measures makes it easy for external dust to enter the bearing, causing scratches on the rolling surface and contamination of the lubricating medium, thereby affecting the lubrication efficiency and service life of the bearing; therefore, a self-lubricating bearing ring for transmissions in new energy vehicles is designed. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating bearing ring for transmission in new energy vehicles, in order to solve the defects of existing bearings that lack heat dissipation devices and dustproof devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-lubricating bearing ring for transmission in new energy vehicles, comprising an outer bearing ring, an excitation block, and an inner bearing ring. A circulation pipe is engaged in a groove in the outer bearing ring, the circulation pipe being tightly attached to a first groove. The first groove is formed on the engagement block, and an engagement shaft is fixedly connected to the engagement block. The engagement shaft is engaged in a hole in the outer bearing ring. A second engagement groove is formed on the outer bearing ring, and a third dustproof ring is engaged in the second engagement groove. A first engagement groove is formed on the outer bearing ring, and a second dustproof ring is engaged in the first engagement groove. A first dustproof ring is fitted into a groove in the second dustproof ring. One end of a spring is fixedly connected to the first dustproof ring, and a limiting plate is fixedly connected to the other end of the spring. An excitation block and a sliding block are fixedly connected to the limiting plate. A through groove is formed on the sliding block, and a limiting block is tightly attached to the sliding block. The limiting block is fitted into the groove of the second dustproof ring.

[0006] As a further technical solution of this utility model, a second groove is provided on the first dustproof ring, and a limiting plate, a sliding block and an excitation block are slidably connected in the second groove.

[0007] As a further technical solution of this utility model, the second dustproof ring is closely attached to the third dustproof ring.

[0008] As a further technical solution of this utility model, the outer ring of the bearing is rotatably connected with balls, and the balls are rotatably connected to the slide rail.

[0009] As a further technical solution of this utility model, the slide rail is formed in the inner ring of the bearing.

[0010] As a further technical solution of this utility model, the inner ring of the bearing is provided with a snap-fit ​​protrusion.

[0011] As a further technical solution of this utility model, the snap-fit ​​protrusion is tightly attached to the groove on the outer ring of the bearing.

[0012] This utility model provides a self-lubricating bearing ring for new energy vehicle transmission. Its advantages include: solid lubricants such as graphite, molybdenum disulfide, and polytetrafluoroethylene are typically embedded in the inner ring material of the bearing. During bearing operation, due to friction and temperature changes, the lubricant in the ring is gradually released to the friction surface. This lubricating film effectively reduces direct metal-to-metal contact, thereby lowering the coefficient of friction and wear rate. The lubricating film also absorbs some heat, helping to control the bearing's temperature rise. The three-layer protection of the first, second, and third dustproof rings effectively prevents dust from entering, avoiding scratches on the rolling surface and contamination of the lubricating medium, thus improving the bearing's lubrication efficiency and service life. Pressing the activation block pushes the sliding block to slide, and the limiting block slides into the through groove, thereby removing the first dustproof ring. The circulating pipe contains a heat-absorbing solution, which significantly improves the heat dissipation capacity of the outer ring of the bearing, slowing down bearing material fatigue and performance degradation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see the appendix Figure 1 - Appendix Figure 4 This utility model provides an embodiment of a self-lubricating bearing ring for a new energy vehicle transmission, comprising an outer bearing ring 1, an excitation block 5, and an inner bearing ring 7. A circulation pipe 2 is engaged in a groove of the outer bearing ring 1, the circulation pipe 2 being tightly fitted to a first groove 14, the first groove 14 being formed on a engaging block 3, a engaging shaft 13 being fixedly connected to the engaging block 3, and the engaging shaft 13 being engaged in a hole in the outer bearing ring 1. A second engaging groove 12 is formed on the outer bearing ring 1, in which a third dustproof ring 11 is engaged. A first engaging groove 9 is formed on the outer bearing ring 1, in which a second dustproof ring 6 is engaged. A first dustproof ring 4 is sleeved in a groove in the second dustproof ring 6, and one end of a spring 16 is fixedly connected to the first dustproof ring 4. The other end of the spring 16 is fixedly connected to a limiting plate 15. An excitation block 5 and a sliding block 17 are fixedly connected to the limiting plate 15. A through groove 19 is provided on the sliding block 17. A limiting block 18 is tightly attached to the sliding block 17. The limiting block 18 is sleeved in the groove of the second dustproof ring 6. The snap-fit ​​block 3 is used to fix the circulation pipe 2. A second groove 21 is provided on the first dustproof ring 4. The limiting plate 15, the sliding block 17 and the excitation block 5 are slidably connected in the second groove 21. The second dustproof ring 6 is tightly attached to the third dustproof ring 11. A ball bearing 10 is slidably connected to the outer ring 1 of the bearing. The ball bearing 10 is slidably connected to the slide rail 20. The slide rail 20 is provided on the inner ring 7 of the bearing.

[0021] Specifically, in use, solid lubricants such as graphite, molybdenum disulfide, and polytetrafluoroethylene are usually embedded in the material of the inner ring 7 of the bearing. When the bearing is running, due to friction and temperature changes, the lubricant in the ring is gradually released to the friction surface. This lubricating film can effectively reduce the direct contact between metals, thereby reducing the coefficient of friction and wear rate. The lubricating film can also absorb some heat, which helps to control the temperature rise of the bearing. The three-layer protection of the first dust ring 4, the second dust ring 6, and the third dust ring 11 can effectively prevent dust from entering, avoid scratches on the rolling surface and contamination of the lubricating medium, thereby improving the lubrication efficiency and service life of the bearing. Pressing the activation block 5 will push the sliding block 17 to slide, and the limiting block 18 will slide into the through groove 19, thereby removing the first dust ring 4. The circulation pipe 2 is filled with a heat-absorbing solution, which can greatly improve the heat dissipation capacity of the outer ring 1 of the bearing and slow down the fatigue and performance degradation of the bearing material.
