Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a single-row oblique groove bearing. Background Art

[0002] When a single-row inclined groove bearing is running, the relative movement between its internal rolling elements and the shaft or bearing seat will cause friction. This friction not only consumes energy, but also converts this energy into heat energy, causing the bearing temperature to rise. However, excessively high bearing temperature will affect the performance of the lubricating oil inside the bearing. As the temperature rises, the viscosity of the lubricating oil will change, resulting in a decrease in its lubricating effect. At the same time, it will accelerate the oxidation and deterioration of the lubricating oil, which not only aggravates the wear of the bearing, but also greatly shortens the service life of the bearing. In order to solve this problem, the traditional method is to continuously add lubricating oil to the bearing to maintain sufficient lubricating oil and avoid high temperature causing it to melt. However, this method is more cumbersome in actual operation and has a poor effect in dissipating heat from the bearing.

[0003] Therefore, it is necessary to propose a single-row inclined groove bearing to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a single-row inclined groove bearing to solve the problem that the traditional method proposed above is to continuously add lubricating oil to the bearing to maintain the lubricating oil sufficient and avoid melting due to high temperature. However, this method is relatively cumbersome in actual operation and has the problem of poor heat dissipation effect on the bearing.

[0005] To achieve the above object, the utility model provides the following technical solution: a single-row oblique groove bearing, comprising an inner ring, the inner wall of the inner ring is fixedly provided with a support frame, the outer wall of the support frame is rotatably provided with a rolling body, the outer wall of the rolling body is rotatably provided with an outer ring, and the outer ring is provided with a heat dissipation part for dissipating heat from the outer ring;

[0006] The heat dissipation part includes a cavity, the inner wall of the outer ring is provided with a cavity, the surface of the outer ring is provided with a plurality of air inlets at equal intervals, the air inlets are connected with the cavity, and the bottom of the outer ring is provided with a plurality of air outlets at equal intervals.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The heat dissipation part of the utility model is mainly used to effectively dissipate the heat generated by the bearing during the rotation process, and the outside air is sucked into the inner part of the outer ring to form a wind flow. When the wind flow passes through the inner part of the bearing, it will take away the heat generated by friction and discharge it from other outlets of the outer ring, thereby achieving an effective heat dissipation effect. In addition, during the rotation process, the wind flow can also play a cleaning role. It can suck in the dust accumulated on the outer ring and discharge it with the wind flow, thereby reducing the friction and wear between the bearing and the dust during operation, while keeping the outer ring of the bearing clean;

[0014] 2. When the bearing rotates, it will carry the lubricating oil in the groove with it. With the help of centrifugal force, the lubricating oil is lifted to a certain height. Once it exceeds the oil outlet hole, it will flow out naturally and be evenly applied to the rolling element, realizing the function of automatic lubrication of the bearing when rotating, ensuring that the bearing always maintains a good lubrication state during continuous operation, thereby improving the performance of the bearing.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 - Figure 5 A single-row oblique groove bearing shown includes an inner ring 1, which is used to support the rolling element 3 of the rolling bearing. A support frame 2 is fixedly provided on the outer wall of the inner ring 1, and the support frame 2 fixes the position of the roller or steel ball to ensure the accuracy and stability of the bearing. The outer wall of the support frame 2 is rotatably provided with a rolling element 3.

[0023] The outer wall of the rolling body 3 is rotatably provided with an outer ring 4, also called an outer sleeve or outer ring, which plays a fixing and supporting role.

[0024] The outer ring 4 is provided with a heat dissipation part for dissipating heat from the outer ring 4, which is mainly used to effectively dissipate heat generated by the bearing during rotation, and to suck outside air into the outer ring 4 to form wind flow. When the wind flow passes through the inside of the bearing, it will take away the heat generated by friction and be discharged from other outlets of the outer ring 4, thereby achieving effective heat dissipation. In addition, during the rotation process, the wind flow can also play a cleaning role. It can suck in the dust accumulated on the outer ring 4 and discharge it with the wind flow, thereby reducing the friction and wear between the bearing and the dust during operation, while keeping the outer ring 4 of the bearing clean.

[0025] The heat dissipation part includes a cavity 501. The inner wall of the outer ring 4 is provided with a cavity 501. The surface of the outer ring 4 is provided with a plurality of air inlets 502 at equal intervals. The air inlets 502 are connected to the cavity 501. The air inlets 502 are gradually inclined on one side close to the cavity 501, so that wind can quickly enter the cavity 501.

[0026] The surface of the outer ring 4 is equidistantly provided with a plurality of protrusions 604, and the protrusions 604 are arranged on one side of the air inlet 502. The main function of the protrusions 604 is to block the direct flow of wind so that the wind can be slightly gathered and change the flow direction after encountering these protrusions 604. At the same time, with the inclined design of the air inlet 502, these blocked and gathered wind flows can be guided more smoothly into the cavity 501, thereby optimizing the path of the wind flow and improving the heat dissipation effect.

[0027] The bottom of the outer ring 4 is provided with a plurality of air outlets 503 at equal intervals. When the air enters the cavity 501 through the air inlet 502, it exchanges heat with the heat in the cavity 501 and then quickly discharges the heat from the air outlets 503, thereby achieving a heat dissipation function.

[0028] The inner wall of the support frame 2 is provided with a through groove 601 for storing lubricating oil, and the surface of the support frame 2 is provided with an oil filling port 602. After filling the lubricating oil, the oil filling port 602 can be blocked by a rubber plug to prevent the lubricating oil in the through groove 601 from leaking out when the bearing rotates.

[0029] The oil filling port 602 is connected to the through groove 601, and a plurality of oil outlet holes 603 are equidistantly provided on the outer wall of the support frame 2. The oil outlet holes 603 are connected to the through groove 601. The side of the oil outlet holes 603 away from the through groove 601 corresponds to the rolling body 3. The side of the oil outlet holes 603 away from the through groove 601 is inclined to facilitate the outflow of the lubricating oil in the through groove 601.

[0030] When the bearing rotates, it will rotate with the lubricating oil in the through groove 601. Due to the centrifugal force of the bearing rotation, the lubricating oil in the through groove 601 will be driven and rotate upward, and then rise. Once the height of the lubricating oil exceeds the oil outlet 603, it will flow out naturally and evenly adhere to the rolling element 3, realizing the function of automatic lubrication of the bearing when rotating, ensuring that the bearing always maintains a good lubrication state during continuous operation, thereby improving the performance of the bearing.
