Abstract
Description
Technical Field
[0001] This utility model relates to a bearing structure, and more particularly to a bearing structure that can significantly extend the service life of the bearing and can detect abnormalities in advance from the torque value, allowing for early replacement and thus avoiding downtime losses due to bearing failure. Background Technology
[0002] In wafer or optoelectronic substrate cleaning equipment, two rotating brushes are used to clean the wafers or optoelectronic substrates. Each brush has a shaft that drives the brush to rotate. One end of the shaft is fixed to a bearing housing via a bearing, which supports the shaft and aids in its rotation. However, the cage in a bearing is a crucial component, playing a vital role in rolling bearings by equidistantly isolating the steel balls, preventing them from falling out, and guiding and rotating them. During operation, especially at high speeds and under complex loads, the cage often withstands significant centrifugal forces, impacts, and vibrations. Therefore, the bearing cage is often the most vulnerable component in a bearing. Once the cage fails, the collisions between the steel balls can lead to bearing damage and even damage to the shaft. Figure 4 The diagram shows a conventional bearing retainer structure 50, which has several ball receiving grooves 5 arranged in a ring. Each ball receiving groove 5 has an opening 51 at both ends connected to a recessed platform 52, forming a retaining spring 521 at the opening 51. When this type of retainer structure faces excessively high impact loads, the intense vibration will cause the balls to impact the retainer, causing the balls to be no longer constrained by the raceway. This results in a higher impact on the retainer structure, which can easily lead to premature wear, fatigue, and sudden breakage of the retainer.
[0003] Bearings and shafts are indispensable core components in various industrial machinery and equipment, and their load capacity directly affects the operating performance and lifespan of the equipment. Bearings with insufficient load capacity can cause damage to themselves and the shaft, and even lead to the failure of the entire equipment, necessitating the replacement of other parts. For this reason, it is essential to develop a bearing structure that addresses the problems of existing technologies and possesses high load capacity for use in high-load operating environments, thereby improving the stability of mechanical operation.

[0041] The inner sidewall 11 of the inner ring 1 can be fixed to the rotating shaft by a rotating shaft, and an outer groove 13 is provided at each end of the outer sidewall 12 of the inner ring 1.
[0042] The outer ring 2 is fitted onto the outer side wall 12 of the inner ring 1, and an inner groove 22 corresponding to the outer groove 13 is provided at each end of the inner side wall 21 of the outer ring 2.
[0043] The two rolling components 3 are disposed between the outer ring 2 and the inner ring 1. Each rolling component 3 includes several rolling elements 31 and a retainer 32. Each retainer 32 has several retaining portions 321, which are correspondingly disposed between the inner groove 22 of the outer ring 2 and the outer groove 13 of the inner ring 1. Each retaining portion 321 is formed by a C-shaped opening, which has a concave bottom 322 and a flat top 323. The rolling elements 31 are accommodated within the retaining portions 321 of each retainer 32, so that the rolling elements 31 of each rolling component 3 are placed in the corresponding outer groove 13 and inner groove 22 of the inner ring 1 and the outer ring 2. In this way, the device disclosed above constitutes a completely new bearing structure 100.
[0044] When this utility model is assembled, each rolling component 31 is placed into the retainers 32 to form the rolling kits 3. These rolling kits 3 are then placed between the outer groove 13 of the inner ring 1 and the inner groove 22 of the outer ring 2 to fix the position of each rolling component 31, maintaining a uniform spacing and appropriate distribution. This guides and drives the rolling components 31 of each rolling kit 3 to roll within the corresponding outer groove 13 and inner groove 22 of the inner ring 1 and outer ring 2. Figure 2 As shown, a bearing structure 100 is formed.

[0048] In a preferred embodiment of the present invention, the angle at which each of the C-shaped openings covers each of the rolling components 31 is 275 degrees to 280 degrees.
[0049] In a preferred embodiment of the present invention, the length of the flat top of the C-shaped opening is equal to or greater than the diameter of the C-shaped opening.
[0050] Therefore, the bearing structure of this invention can significantly extend the service life of bearings and can detect abnormalities in advance through torque values, allowing for timely replacement and avoiding downtime losses due to bearing failure.
