Description

Bearing

The invention relates to the field of mechanical technology, in particular to a bearing.

Bearings are components that fix and reduce the coefficient of friction of the load during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, the mechanism for reducing the coefficient of friction during power transmission and maintaining the center position of the shaft is fixed.

Bearings are a very important component in contemporary mechanical equipment. Its accuracy, performance, longevity and reliability play a decisive role in the accuracy, performance, longevity and reliability of the mainframe.

Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process.

According to the friction properties of moving components, bearings can be divided into two types: rolling bearings and sliding bearings.

In general, the bearing has an outer ring, an inner ring and a rolling member disposed between the outer ring and the inner ring, and a shaft body is mounted on the inner ring, and the shaft is connected to the mechanical device through the shaft body. In the prior art, no matter what kind of frictional bearing, the shaft body is installed in the shaft hole of the bearing. When the bearing rotates, friction between the shaft body and the bearing occurs due to high speed rotation, and The vibration of the equipment will cause wear between the shaft body and the bearing, shortening the life of the bearing.

In order to solve the above problems, the present invention is provided with a shock-proof ring at the shaft hole of the bearing, which has reduced the wear between the shaft body and the bearing, and increases the bearing life.

More preferably, the anti-vibration ring (3) is a hollow cylindrical colloid made of silicone material, and the height of the anti-vibration ring (3) is equal to the height of the inner ring (2).

More preferably, between the outer ring (1) and the inner ring (2), a mounting groove (11) is formed, in which the rolling member is mounted, and in the outer ring (1) and Sealing rings (12) are attached to both end faces of the inner ring (2) to seal the mounting groove (11).

More preferably, the rolling member is a ball (5).

More preferably, the shaft body (4) is a screw, and the screw is provided with a thread; the screw is fixed in the shaft hole (21) and is interlocked with the inner ring (2).

More preferably, the shaft body (4) is a shaft, and the shaft rod is fixed in the shaft hole (21) and interlocked with the inner ring (2).

More preferably, the anti-vibration ring (3) has an inner wall provided with a non-slip thread.

Compared with the prior art, the effects of the present invention are as follows:

The first point: The new type is provided with an anti-vibration ring at the axial hole of the inner ring, which effectively reduces the wear caused between the inner ring and the shaft body due to the rotation of the inner ring and the vibration of the mechanical device, thereby increasing the bearing life. Life.

The second point: sealing rings are arranged on both end faces of the outer ring and the inner ring to seal the mounting groove, which can effectively reduce the consumption of lubricating oil, prevent the volatilization of lubricating oil and prevent dust from entering the mounting groove, and affect the operation of the bearing. .

The following is a detailed description of the embodiment shown in the drawings. As shown in FIGS. 1 to 3, a bearing includes an outer ring (1), an inner ring (2), and a ring disposed on the outer ring. (1) a rolling member between the inner ring (2), the inner ring (2) and the outer ring (1) are mutually rotatable by a rolling member, and the inner ring (2) is formed with a shaft body (4) The inserted shaft hole (21) is provided with an anti-vibration ring (3) attached to the shaft hole (21), and the anti-vibration ring (3) abuts against the inner wall of the shaft hole (21).

Specifically, a mounting groove (11) is formed between the outer ring (1) and the inner ring (2), the rolling member is installed in the mounting groove (11), and the rolling elements are balls (5) and balls (5). Uniformly disposed in the mounting groove (11), the outer ring (1) and the inner ring (2) are relatively rotated by the ball (5). A sealing ring (12) is mounted on both ends of the outer ring (1) and the inner ring (2), and the sealing ring (12) seals the mounting groove (11), and can be installed in the mounting groove (11) The lubricating oil can effectively reduce the friction generated by the rotation and the generated heat, and can also prevent dust and the like from entering the installation groove, thereby affecting the operation of the bearing.

The anti-vibration ring (3) is made of a material with high-strength buffer shock absorption and shock resistance. The anti-vibration ring (3) in this embodiment is a hollow cylindrical colloid made of silicone rubber, and the anti-vibration ring (3) is high. The degree is equal to the height of the inner ring (2), and the anti-vibration ring (3) abuts against the inner wall of the shaft hole of the inner ring (2). The shaft body (4) is a screw, the screw is provided with a thread, the screw is fixed in the shaft hole (21), the screw is threaded on the anti-vibration ring (3), and the friction coefficient is large due to the anti-vibration ring (3) There is no relative rotation between the screw and the anti-vibration ring (3).
