A cylindrical bearing roller

Abstract

This utility model provides a cylindrical bearing roller, including a roller structure comprising a roller body, auxiliary shafts at the top and bottom of the roller body, an air chamber inside the roller body, a partition on the inner wall of the air chamber, and air inlet grooves on both sides of the auxiliary shafts. This utility model is rationally designed. Through the air inlet grooves at the top and bottom of the roller body, as the roller body rotates, external air enters the air chamber through the inlet grooves, then enters the other side of the air chamber through the gap at the bottom of the partition and exits through the air inlet groove on the other side. This achieves airflow and dissipates heat from the inside of the roller body, preventing heat accumulation inside the roller body. Simultaneously, the air inlet grooves on both sides switch during the rotation of the roller body.

Description

Technical Field

[0001] This utility model mainly relates to the field of bearing rollers, specifically to a cylindrical bearing roller. Background Technology

[0002] Rolling bearings are crucial basic components in modern mechanical equipment, and their performance directly affects the precision, efficiency, and lifespan of the entire transmission system. As the core force-bearing element of a rolling bearing, the rollers in cylindrical bearings generate a significant amount of frictional heat between the rollers and the inner and outer raceways when operating under high-speed, heavy-load conditions. This heat primarily originates from elastic hysteresis, differential sliding, friction between the rollers and the flanges, and the viscous shearing action of the lubricant.

[0003] The accumulation of heat will cause the internal temperature of the bearing to rise sharply, leading to a series of serious problems, such as material performance degradation. Common bearing steels (such as GCr15) will have significantly reduced hardness after exceeding their tempering temperature (usually about 120-150℃). When ball bearings are used for a long time, their temperature will approach or exceed 120-150℃, which will cause a decrease in the wear resistance of the rollers inside the ball bearing. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a cylindrical bearing roller to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a cylindrical bearing roller, comprising a roller structure, wherein the number of roller structures is set to multiple, and a side support structure is provided between two roller structures;

[0008] A roller structure includes a roller body, with auxiliary shafts at the top and bottom of the roller body, an air chamber inside the roller body, a partition on the inner wall of the air chamber, and air inlet slots on both sides of the auxiliary shaft.

[0009] Furthermore, the outer wall of the roller body is provided with a fitting groove, and the number of the fitting grooves is set to two, which are symmetrically distributed on the top and bottom of the roller body.

[0010] Furthermore, the side support structure includes a connecting ring, with fitting rings at both ends of the connecting ring, the fitting rings being slidably connected to the fitting groove, and the number of the connecting rings being two.

[0011] Furthermore, an air inlet is provided inside the connecting ring, and a guide plate is provided on the outer wall of the air inlet.

[0012] Furthermore, the air intake slot is connected to the air chamber, and a gap is provided between the air chamber and the partition.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0015] This invention utilizes air inlet slots at the top and bottom of the roller body. As the roller body rotates, external air enters the air chamber through these slots, then flows through a gap at the bottom of the partition to the other side of the air chamber and exits through the air inlet slot on the other side. This achieves airflow and dissipates heat from the inside of the roller body, preventing heat buildup. The two air inlet slots switch positions as the roller body rotates. By dissipating heat from the roller body, the wear resistance of the bearing rollers is improved, ensuring stable operation at a relatively stable temperature. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0022] Reference Figures 1-3 A cylindrical bearing roller includes a roller structure 1, wherein the number of roller structures 1 is set to multiple, and a side support structure 2 is provided between two roller structures 1.

[0023] A roller structure 1 includes a roller body 101. Auxiliary shafts 103 are provided at the top and bottom of the roller body 101. An air chamber 105 is formed inside the roller body 101. A partition 106 is provided on the inner wall of the air chamber 105. Air inlet grooves 104 are formed on both sides of the auxiliary shafts 103. Two fitting grooves 102 are formed on the outer wall of the roller body 101, symmetrically distributed at the top and bottom of the roller body 101. The air inlet grooves 104 communicate with the air chamber 105. A gap is provided between the air chamber 105 and the partition 106. The outer wall of the connecting ring 201 is fitted with... The connecting ring 202 is aligned with the fitting groove 102 to limit the position of the roller body 101. Then, during the rotation of the roller body 101, external air enters the air chamber 105 through the air inlet groove 104 on one side of the auxiliary shaft 103, and enters the other side of the air chamber 105 along the gap between the partition 106 and the bottom, and is discharged through the air inlet groove 104 on the other side. This can drive the heat inside the roller body 101 to be discharged. When the roller body 101 rotates, the air inlet and outlet of the two air inlet grooves 104 can be switched to achieve the function of heat dissipation. In addition, the side support structure 2 can prevent the displacement of the moving positions between the multiple roller structures 1.

[0024] Furthermore, the side support structure 2 includes a connecting ring 201, with fitting rings 202 at both ends. The fitting rings 202 are slidably connected to the fitting groove 102. The number of connecting rings 201 is set to two. An air inlet 203 is opened inside the connecting ring 201. A guide plate 204 is provided on the outer wall of the air inlet 203. The side support structure 2 and the roller structure 1 are placed inside the bearing. During the rotation of the bearing, the side support structure 2 and the roller structure 1 rotate inside the bearing. When the connecting ring 201 rotates around the bearing, the external air is blocked by the guide plate 204, allowing the air to enter the bearing and be discharged through the air inlet 203 inside the bottom connecting ring 201, thereby achieving airflow for heat dissipation. The guide plate 204 is only installed on the top of the top connecting ring 201, and the bottom connecting ring 201 does not have a guide plate 204 installed on the bottom.

[0025] The specific working process of this utility model is as follows:

[0026] Roller rotates → Auxiliary shaft 103 rotates together with roller body 101;

[0027] Air intake → External air enters the air chamber 105 through the air intake slot 104 on one side;

[0028] Airflow passes through → air flows along the gap at the bottom of partition 106 to the other side of the air chamber;

[0029] Air is discharged through the air intake 104 on the other side;

[0030] Heat dissipation complete → Airflow carries away the heat inside the rollers, achieving continuous heat dissipation;

[0031] Inlet / outlet switching → When the roller rotates, the air inlet slots on both sides alternately serve as air inlets / outlets, achieving bidirectional heat dissipation.
