A heat dissipation bearing roller

Abstract

This invention provides a heat-dissipating bearing roller, comprising a roller structure including a roller body. The outer wall of the roller body has heat dissipation grooves, and rotating rings are provided at the top and bottom of the heat dissipation grooves. A through groove is formed inside the roller body. This invention is reasonably designed. By providing a through groove inside the roller body, which is fixed by a threaded shaft and two support rings, and allowing the roller body to rotate, and by placing lubricant or coolant inside the through groove, the roller body allows external air to contact the heat dissipation grooves during rotation. The heat dissipation grooves cool the lubricant or coolant inside the through groove, thereby reducing the heat of the roller body and preventing heat buildup that could lead to lubrication failure.

Description

Technical Field

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

[0002] Bearings, as core basic components of modern industry, are widely used in high-precision, high-load, and high-speed equipment fields such as machine tools, automobiles, wind power, and aerospace. The performance of bearings directly determines the precision, efficiency, reliability, and lifespan of the main equipment. Among them, rolling elements (such as rollers) are the most critical load-bearing and moving parts of the bearing, and their working performance is crucial to the entire bearing system and even the entire transmission system.

[0003] Under extreme conditions of high speed and heavy load, bearings generate a large amount of frictional heat due to factors such as contact friction between rollers and raceways, elastic hysteresis of materials, and viscous shear of lubricants. If this heat cannot be dissipated in a timely and effective manner, it will cause a sharp rise in the internal temperature of the bearing, leading to a series of serious problems:

[0004] Lubrication failure: Excessively high temperatures can reduce the viscosity of lubricating oil, making it difficult to form an effective lubricating film. This leads to poor lubrication, increased friction and wear, and even serious failures such as galling and seizing. Furthermore, high temperatures can also cause the base oil of the lubricating grease to separate, oxidize, and coke, completely losing its lubricating function. Utility Model Content

[0016] This invention features a through-groove inside the roller body, which is fixed by a threaded shaft and two support rings. The roller body can rotate on its own.

[0022] 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.

[0023] Reference Figures 1-3A heat dissipation bearing roller includes a support frame structure 1, the number of support frame structures 1 is set to two, and a roller structure 2 is rotatably connected between the two support frame structures 1. The number of roller structures 2 is set to multiple, and the multiple roller structures 2 are arranged in a ring array inside the support frame structure 1.

[0024] The roller structure 2 includes a roller body 201. The outer wall of the roller body 201 has a heat dissipation groove 202. The top and bottom of the heat dissipation groove 202 are provided with rotating rings 203. The inside of the roller body 201 has a through groove 204. The top and bottom of the inner wall of the through groove 204 are provided with rotating sealing rings. The through groove 204 is rotatably connected to the insert ring 102 through the rotating sealing rings. When the roller body 201 rotates, the rotating ring 203 rotates on the outer wall of the insert ring 102, and the heat dissipation groove 202 comes into contact with the outside air. Then, the lubricant or coolant inside the through groove 204 is dissipated through the heat dissipation groove 202, thereby preventing heat from accumulating inside the roller body 201.

[0025] Furthermore, the support frame structure 1 includes a support ring 101 and a threaded shaft 104. The support ring 101 has a plurality of insert rings 102 inside, arranged in a circular array at the bottom of the support ring 101. Each insert ring 102 has an internal threaded groove 103 inside. The threaded shaft 104 has a hexagonal groove 105 at its top. The outer wall of the threaded shaft 104 is threadedly connected to the inner wall of the internal threaded groove 103. The threaded shaft 104 is configured with... A gap is provided between the threaded shaft 104 and the through groove 204 on the inner wall of the through groove 204. When the roller structure 2 needs to be installed, the roller structure 2 is placed between the two support rings 101, and the inner wall of the through groove 204 is rotatably connected to the outer wall of the insert ring 102. Then, lubricant or coolant is injected into the inside of the roller structure 2. Then, the threaded shaft 104 is inserted into the inside of the internal thread groove 103 and connected and sealed by threads, so that the lubricant or coolant is sealed inside the through groove 204.

[0026] Assembly stage:

[0027] Multiple roller structures 2 are arranged in a ring array between two support rings 101.

[0028] The insertion ring 102 is connected to the through groove 204, and a rotating seal ring is used to achieve a rotational connection.

[0029] Inject lubricating oil or coolant into the through groove 204.

[0030] The threaded shaft 104 is screwed into the internal thread groove 103 to complete the sealing and fixing.

[0031] Work phase:

[0032] When the bearing is running, the roller body 201 rotates with the shaft.

[0033] The heat dissipation slot 202 comes into contact with air, enhancing the heat dissipation effect.

[0034] The liquid in the through-channel 204 absorbs heat from the rollers through thermal conduction and dissipates it through the heat dissipation channel 202.

[0035] The rotating ring 203 ensures smooth rotation between the roller and the support structure, reducing frictional heat.

[0036] The heat dissipation grooves 202 can be spiral, axial straight grooves, or mesh-like to increase the heat dissipation area and enhance airflow efficiency.
