Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a stainless steel bearing with a long service life. Background Technology

[0002] Bearings are crucial basic components in various mechanical equipment, supporting rotating parts, reducing friction during movement, and ensuring rotational accuracy. Stainless steel bearings, due to their excellent corrosion resistance, are widely used in food processing, chemical engineering, marine engineering, and many other fields. However, during prolonged high-speed operation, existing stainless steel bearings experience a rapid increase in internal temperature due to frictional heat. If this heat cannot be dissipated promptly, it will reduce the viscosity of the lubricating oil, worsening lubrication and accelerating wear between bearing components. Furthermore, the high temperature will cause thermal expansion of the stainless steel material, altering the bearing's fit precision, further shortening its lifespan, and even leading to equipment failure, affecting the continuity and stability of production. Therefore, effectively solving the heat dissipation problem of stainless steel bearings and extending their service life has become an urgent technical challenge. Utility Model Content

[0003] The main objective of this invention is to provide a stainless steel bearing with a long service life, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stainless steel bearing with a long service life, comprising a bearing assembly, wherein a heat dissipation mechanism is provided in the middle of the bearing assembly;

[0005] The bearing assembly includes an outer ring, an inner ring, a plurality of balls, and two cages. The outer periphery of the inner ring is disposed in the middle of the outer ring, the plurality of balls are disposed between the outer ring and the inner ring, and the plurality of balls are disposed at equal intervals between the two cages.

[0006] Preferably, dust covers are provided on the left and right sides between the outer ring and the inner ring.

[0007] Preferably, the heat dissipation mechanism includes a support ring and copper blades. The outer periphery of the support ring is fixedly connected to the inner wall of the inner ring, and the copper blades are fixedly connected to the inner wall of the inner ring at equal intervals. The copper blades are disposed between the copper blades and the inner ring.

[0008] Preferably, the heat dissipation mechanism further includes a connecting ring, a connecting rod, fan blades, and heat dissipation holes.

[0010] Preferably, protective covers are provided on the left and right sides of the outer ring, and the protective covers are provided on the outer periphery of the fan blade.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-3 As shown, a stainless steel bearing with a long service life includes a bearing assembly 1, and a heat dissipation mechanism 2 is provided in the middle of the bearing assembly 1.

[0019] In this embodiment, the bearing assembly 1 includes an outer ring 101, an inner ring 102, a plurality of balls 103, and two cages 104. The outer periphery of the inner ring 102 is disposed in the middle of the outer ring 101. The plurality of balls 103 are disposed between the outer ring 101 and the inner ring 102. The plurality of balls 103 are equally spaced between the two cages 104. Dust covers 3 are provided on the left and right sides between the outer ring 101 and the inner ring 102.

[0020] Specifically, the ball 103 is fixed by the cage 104, and the sliding friction of the ball 103 during relative motion is converted into rolling friction.

[0021] In this embodiment, the heat dissipation mechanism 2 includes a support ring 201 and copper blades 202. The outer periphery of the support ring 201 is fixedly connected to the inner wall of the inner ring 102. The copper blades 202 are fixedly connected to the inner wall of the inner ring 102 at equal intervals. The copper blades 202 are disposed between the copper blades 202 and the inner ring 102. The heat dissipation mechanism 2 also includes a connecting ring 203, a connecting rod 204, a fan blade 205, and heat dissipation holes 206. The inner wall of the fan blade 205 is fixedly connected to the outer periphery of the connecting rod 204. The connecting rod 204 is fixedly connected to the outer periphery of the connecting ring 203. One end of the connecting ring 203 is fixedly connected to the left and right ends of the support ring 201. The fan blade 205 is aligned with the heat dissipation holes 206. Multiple heat dissipation holes 206 are equally spaced in the middle of the outer ring 101. The front and rear sides of the heat dissipation holes 206 are funnel-shaped. Protective covers 207 are provided on the left and right sides of the outer ring 101. The protective covers 207 are disposed on the outer periphery of the fan blade 205.

[0022] Specifically, a fan is formed by copper blades 202. When the inner ring 102 rotates, the copper blades 202 rotate, causing airflow. This allows outside cold air to pass through the copper blades 202, thus dissipating heat from the copper blades 202 and reducing the temperature of the inner ring 102. Furthermore, the connecting ring 203 and connecting rod 204 drive the fan blades 205 to rotate, allowing outside cold air to pass through the heat dissipation holes 206 and dissipate heat from the outer ring 101. This effectively reduces the temperature of the bearing assembly 1 and extends its service life.

[0023] Working principle:

[0024] The ball bearing 103 is fixed by the cage 104. The sliding friction of the ball bearing 103 during relative motion is converted into rolling friction. The copper blades 202 form a fan. When the inner ring 102 rotates, the copper blades 202 rotate, which drives the airflow. The outside cold air passes through the copper blades 202 to dissipate heat from the copper blades 202, thereby reducing the temperature of the inner ring 102. Furthermore, the connecting ring 203 and the connecting rod 204 drive the fan blades 205 to rotate, which allows the outside cold air to pass through the heat dissipation holes 206 to dissipate heat from the outer ring 101. This effectively reduces the temperature of the bearing assembly 1 and extends its service life.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
