Description

Technical Field

[0001] This utility model belongs to the field of bearings, and specifically relates to a fiber-wound bearing. Background Technology

[0002] Bearings are key components in mechanical systems used to reduce friction between moving parts and support rotational or reciprocating motion. Their main function is to bear loads through rolling or sliding contact, ensuring the efficient and smooth operation of mechanical devices. Bearings are widely used in automobiles, aerospace, industrial equipment, and other fields, and are an indispensable part of modern mechanical design. Traditional bearings are usually made of metal materials (such as steel or copper alloys), which are prone to noise and vibration during operation. This problem mainly stems from their rigid structure and contact mechanics characteristics. In rolling bearings, the periodic contact between the rolling elements and the raceway generates high-frequency vibrations, especially under high-speed or variable load conditions. This vibration is transmitted and amplified through the metal structure, forming significant noise. Therefore, we aim to design a fiber-wound bearing to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fiber-wound bearing to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a fiber-wound bearing, comprising: a bearing housing, wherein a bearing body is disposed inside the bearing housing, and a lubrication mechanism is disposed on the bearing body;

[0005] The bearing body includes a bearing outer ring, a fixing groove is provided on the outer surface of the bearing outer ring, and an outer fiber winding mold core is integrally fixedly connected to the inner side of the bearing outer ring.

[0006] The bearing body also includes an inner bearing ring, and an inner fiber winding mold core is integrally and fixedly connected to the outer side of the inner bearing ring. Both the outer and inner bearing rings are made of titanium alloy. By setting the outer and inner bearing rings of titanium alloy, the bearing body has advantages in high strength, corrosion resistance and lightweight. At the same time, the fiber winding mold core further reduces weight and enhances damping performance, effectively absorbing vibration and impact and reducing noise.

[0007] In a preferred embodiment, the bearing body further includes balls, and a retainer is provided on the outer side of the balls to ensure uniform arrangement between the balls. The balls are movably fitted into the raceway formed by the outer fiber winding mold core and the inner fiber winding mold core.

[0008] In a preferred embodiment, the bearing housing includes a base and a bearing cover. The base and the left and right sides of the shaft groove cover are integrally fixedly connected with connecting ears. The connecting ears on both sides of the base and the connecting ears on both sides of the shaft groove cover are fixedly connected by screws.

[0009] In a preferred embodiment, the inner sides of the base and the bearing cover are integrally fixedly connected with fixing blocks for limiting the bearing body. The fixing blocks on the inner sides of the bearing seat and the bearing cover cooperate with the fixing groove on the outer side of the bearing to fix the outer ring of the bearing.

[0010] In a preferred embodiment, the bearing outer ring and the outer fiber winding core form a hollow structure for filling with oil-absorbing cotton.

[0011] In a preferred embodiment, the lubrication mechanism includes an oil-absorbing cotton, which fills the cavity formed by the outer ring of the bearing and the outer fiber winding core to store lubricating oil.

[0012] In a preferred embodiment, the outer fiber winding mold core is provided with several sets of lubrication micropores to ensure stable delivery of lubricating oil to the inner side of the outer fiber winding mold core. The oil storage cotton stores the lubricating oil, and the lubricating oil achieves long-term self-lubrication through the lubrication micropores when the bearing is running.

[0013] In a preferred embodiment, the upper end of the outer ring of the bearing is provided with an oil injection hole, which is connected to the cavity for replenishing lubricating oil, and a sealing plug is threadedly connected inside the oil injection hole.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By setting up a bearing body composed of a titanium alloy bearing outer ring, a bearing inner ring, and an outer fiber-wound mold core and an inner fiber-wound mold core, the bearing body's high strength, corrosion resistance, and lightweight advantages are improved. At the same time, the fiber-wound mold core further reduces weight and enhances damping performance, effectively absorbing vibration and impact and reducing noise.

[0016] 2. By setting up a lubrication mechanism, continuous lubrication can effectively reduce the friction between the balls and the fiber winding die core, reduce the wear on the surface of the fiber winding die core and the balls, and significantly extend the service life of the bearing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 3 As the first embodiment of this utility model:

[0028] A fiber-wound bearing includes: a bearing housing 1, a bearing body 2 disposed inside the bearing housing 1, and a lubrication mechanism 3 disposed on the bearing body 2;

[0029] The bearing body 2 includes a bearing outer ring 21, a fixing groove 22 is provided on the outer surface of the bearing outer ring 21, and an outer fiber winding mold core 23 is integrally fixedly connected to the inner side of the bearing outer ring 21.

[0030] The bearing body 2 also includes an inner bearing ring 24, and an inner fiber winding mold core 25 on the outside of the inner bearing ring 24. Both the outer bearing ring 21 and the inner bearing ring 24 are titanium alloy structures. By setting the titanium alloy outer bearing ring 21 and the inner bearing ring 24, the high strength, corrosion resistance and lightweight advantages of the bearing body 2 are improved. At the same time, the fiber winding mold core further reduces the weight and enhances the damping performance, effectively absorbing vibration and impact and reducing noise.

[0031] The bearing body 2 also includes balls 26. A retainer 27 is provided on the outer side of the balls 26 to ensure that the balls 26 are evenly arranged. The balls 26 are movably fitted into the raceway formed by the outer fiber winding mold core 23 and the inner fiber winding mold core 25.

[0032] The bearing housing 1 includes a base 11 and a bearing cover 12. The base 11 and the left and right sides of the shaft groove cover are integrally fixedly connected with connecting ears 13. The connecting ears 13 on both sides of the base 11 and the connecting ears 13 on both sides of the shaft groove cover are fixedly connected by screws.

[0033] The inner sides of the base 11 and the bearing cover 12 are integrally fixedly connected with fixing blocks 14 for limiting the bearing body 2. The fixing blocks 14 on the inner sides of the bearing seat 1 and the bearing cover 12 cooperate with the fixing groove 22 on the outer side of the bearing to fix the outer ring 21 of the bearing.

[0034] The outer ring 21 of the bearing and the outer fiber winding core 23 form a hollow structure for filling oil-absorbing cotton 31.

[0035] Specifically, during use, the fixing groove 22 of the bearing outer ring 21 is first fitted into the fixing block 14 on the inner side of the base 11. Then, the bearing cover 12 is connected to the base 11 through the connecting lug 13, and the fixing block 14 on the inner side of the bearing cover 12 is simultaneously fitted into the fixing groove 22 of the bearing outer ring 21. Finally, the base 11 and the bearing cover 12 are fixed with external bolts to complete the fixed installation of the bearing outer ring 21. Then, the external drive shaft is sleeved inside the bearing inner ring 24. The bearing outer ring 21 and the bearing inner ring 24 are both integrally formed of titanium alloy, outer fiber winding mold core 23 and inner fiber winding mold core 25, which improves the high strength, corrosion resistance and lightweight advantages of the bearing body 2. The outer fiber winding mold core 23 and the inner fiber winding mold core 25 further reduce the weight and enhance the damping performance, effectively absorb vibration and impact, reduce the "bouncing" phenomenon of the balls 26 and improve the smoothness of movement.

[0036] Please see Figure 1 , Figure 2 as well as Figure 4 As a second embodiment of this utility model:

[0037] The lubrication mechanism 3 includes an oil-absorbing cotton 31, which fills the cavity formed by the bearing outer ring 21 and the outer fiber winding core 23 to store lubricating oil.

[0038] The outer fiber winding mold core 23 is provided with several sets of lubrication micropores 32 to ensure that the lubricating oil is stably delivered to the inner side of the outer fiber winding mold core 23. The oil storage cotton 31 stores the lubricating oil, and the lubricating oil achieves long-term self-lubrication through the lubrication micropores 32 when the bearing is running.

[0039] An oil injection hole 33 is provided at the upper end of the outer ring 21 of the bearing. The oil injection hole 33 is connected to the cavity and is used to replenish lubricating oil. A sealing plug 34 is threadedly connected inside the oil injection hole 33.

[0040] Based on the above embodiments, further, during the use of the bearing, the oil-absorbing cotton 31 forms microcapillaries with its porous fiber structure, which utilizes the surface tension of the liquid to allow the oil to spontaneously penetrate and diffuse evenly. When the amount of oil at the micropores of the lubricating oil consumption end decreases, the oil-absorbing cotton 31 forms a dynamic balance due to capillary force, automatically replenishing the oil to the low-pressure area. At the same time, the surface tension of the pores can prevent leakage, thereby providing stable oil supply without the need for external power, reducing fiber entanglement with the mold core and wear on the surface of the ball 26, and significantly extending the service life of the bearing.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
