Description

Technical field:

[0001] The invention discloses a bearing that never needs oiling and relates to the field of mechanical parts, in particular to a retaining frame for a bearing. Background technology:

[0002] Rolling bearings generally consist of an inner ring, an outer ring, rolling elements, and a cage. The primary wear and tear caused by high-speed bearing operation is friction, primarily rolling friction and sliding friction. Sliding friction primarily occurs at the contact surfaces between the rolling elements and raceways, between the rolling elements and cage pockets, between the cage and the ring guide ribs, and between the roller end faces and the ring guide ribs. Sliding friction in rolling bearings inevitably causes wear on bearing components, leading to premature loss of bearing precision or decreased rotational accuracy, increased bearing vibration, and reduced bearing life. Reducing bearing friction not only improves bearing energy consumption but also significantly increases bearing life. The primary factors contributing to rolling friction in bearings are machining quality and the roughness of the contact surface between the rolling elements and raceways. The majority of sliding friction in bearings is caused by the cage, which is unavoidable due to the inherent structure of the rolling elements and cage.

[0003] The rolling isolation cage bearing I invented previously has the disadvantage that the single-speed isolation roller can only isolate the rolling elements but cannot bear the load. A single-speed isolation roller is used to isolate two large rollers. After running for a long time, the inner and outer auxiliary rings show signs of deviation from the center, causing the four positioning bearing rollers to fall apart. After testing, it was found that this is an immature technology.

[0004] The rolling isolation cage bearings and double shoulder isolation rollers are very unreasonable in design, waste materials, cause unnecessary rolling friction damage to the inner and outer auxiliary rings, and add unnecessary burden to the overall structure. In the design of national standard bearings, it is impossible to design the bearing capacity of the national standard and it is impossible to mass-produce and assemble. Summary of the invention:

[0005] The purpose of the present invention is to solve a series of disadvantages brought about by the traditional bearing retainer form and provide a bearing that never needs oiling and has a novel structure and can ensure the bearing to continue to operate at high speed under non-lubricated conditions.

[0006] In order to achieve the above purpose, the present invention provides a bearing that never needs to be oiled, and the technical solution is to eliminate the sliding friction between the previous large roller and the retaining frame through the relative rolling method composed of the large roller, the inner support roller, the outer support roller, the locking roller, and the single-speed isolation roller.

[0007] The present invention provides a bearing that never needs oiling, which is an improvement on the rolling isolation cage bearing invented by me before. The rolling isolation cage bearing is composed of an inner auxiliary ring, an outer auxiliary ring, a single-speed isolation roller, a double-speed isolation roller, an inner support roller and an outer support roller.

[0008] A bearing that never needs lubrication. The previous single-stage isolation roller that isolated two large rollers was replaced with an isolation structure consisting of four rollers that isolated two large rollers.

[0009] The invention discloses a bearing that never needs oiling. The previous double-stage isolation roller and single-stage isolation roller are used to isolate two large rollers. Now, the structure composed of a locking roller, a single-stage isolation roller, an inner support roller and an outer support roller is used to isolate the two large rollers.

[0010] Design of the locking roller: The length between the two retaining rings on the locking roller is equal to the length of the large roller, the length of the inner support roller, and the length of the outer support roller. The outward length of the two retaining rings on the locking roller is equal to the width of the inner auxiliary ring and the outer auxiliary ring. The two retaining rings on the locking roller are characterized by a trapezoidal axial cross-sectional area, which reduces sliding during rotation.

[0011] Locking rollers: The two retaining rings above can lock the large roller, inner support roller and outer support roller on the same plane.

[0012] The current single-speed isolation roller has retaining rings on both sides, which are flat on the outermost side and inclined on the inner side. The purpose is to reduce the sliding friction between the inner auxiliary ring, the outer auxiliary ring and the outermost retaining ring during rotation.

[0013] The locking roller and the single-speed isolation roller are of different lengths. When combined together, it can be seen from the overall annular structure that the gap between the locking roller and the single-speed isolation roller forms annular grooves at the two ends. The inner auxiliary ring and the outer auxiliary ring are just placed inside, stably positioning and rotating all the rollers.

[0014] After such improvements, the load-bearing capacity of the full-complement roller bearing has been formed. All rollers are in rolling isolation, which improves the overall load-bearing capacity of the bearing. The two end faces of the bearing can be the same as the long-gauge bearing and are both flat, achieving the normal function of the rolling isolation cage bearing I invented before, solving all the drawbacks of the rolling isolation cage bearing and the drawbacks of conventional bearing cages. It can be connected with conventional bearings for mass production, achieving a bearing that never needs to be lubricated. Its invention is creative, novel and practical. It can run normally at high speed without lubricating oil, improving the load-bearing capacity and quality of conventional bearings. Description of the drawings:

However, testing has shown that this can occur during high-speed operation, leading to the bearing becoming stuck. The inner and outer auxiliary rings prevent this from happening during high-speed operation.

[0035] A bearing that never needs oiling is modified based on a rolling isolation cage bearing invented by me before, and the patent application number is CN201420554838.0.

[0036] The main improvements are: the previous external structure showed the presence of independent single-stage isolation rollers and two double-stage isolation rollers combined. The current external structure only shows the single-stage isolation roller and locking roller. Internally, the previous single-stage isolation roller and large isolation roller have been replaced with locking rollers, single-stage isolation rollers, and inner and outer support rollers isolating the large roller. The previous two double-stage isolation rollers, with inner and outer support rollers isolating the large roller, have been replaced with single-stage isolation rollers, locking rollers, and inner and outer support rollers isolating the large roller. Because the previous single-stage isolation roller isolated the two large rollers, a significant problem existed: the lack of radial support points meant that the outer and inner auxiliary rings could not maintain their original design positions. After a period of operation, they would automatically deviate from their original positions, causing the rolling isolation rollers to fall apart and become stuck. After 10 years of various experiments and modifications, I, Yan Jiaju, have resolved this problem of long-term seizure and now meet the requirements of a bearing that never needs oiling.
