Abstract

The invention discloses a bearing. The bearing comprises an outer ring, an inner ring, a plurality of rolling bodies and a holder. The inner ring, the outer ring and the holder are all of an annular structure and are arranged concentrically. The outer wall of the outer ring and the outer wall of the inner ring are each provided with a sound insulation layer. The diameter of a channel directly formed by the inner wall of the outer ring and the outer wall of the inner ring is kept unchanged, and a plurality of pits are arranged on the outer wall of the parts, on the two sides of the channel, of the inner ring and on the inner wall of the outer ring. The holder is provided with a plurality of pocket holes. The long axes of the pocket holes are perpendicular to the rotation plane where the holder is located. The rolling bodies are arranged in the pocket holes. Each rolling body is composed of a first trapezoidal part, a second trapezoidal part and a connection part. The bearing provided by the invention is long in life, simple to assemble, good in mute effect and low in cost.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. They are mainly used to determine the relative movement position of the rotating shaft and other parts, support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In addition, the bearing also needs to support the rotating shaft or other moving body, guide the rotating or moving motion and bear the load transmitted by the shaft or parts on the shaft. [0003] Although the early simple ball bearings can be traced back to BC, it was not until 1883 that Friedrich Fischer proposed the idea of ​​using a suitable production machine to grind steel balls of the same size and accurate roundness, and the bearing was established. The basis of industry. By the beginning of the 20th century, bearing technology entered the moder...

AI Technical Summary

Problems solved by technology

However, because the double-row tapered roller bearing involves too many parts, the production and assembly process is complicated and cumbersome, which is not conducive to large-scale promotion and use.

[0005] In addition, the bearing will generate a lot of noise during operation, which has a very obvious impact on the environment, but currently there is no technology that can effectively eliminate the noise generated during the operation of the bearing
