Description

Technical Field

[0002] An eccentric workpiece refers to a workpiece in which the axes of the outer circle and the outer circle or the outer circle and the inner hole are parallel but do not coincide, with a distance offset. The distance between these two parallel axes is called the eccentricity. A part with eccentricity between outer circles is called an eccentric shaft or eccentric disc; a part with eccentricity between the outer circle and the inner hole is called an eccentric sleeve. In mechanical transmission, the conversion between rotary motion and reciprocating linear motion or reciprocating linear motion and rotary motion is generally accomplished by using eccentric parts.

[0003] In the existing eccentric sleeves during use, the adaptability of the eccentric sleeves is narrow, and they cannot meet the problem of adaptive adjustment for different eccentric errors. During use, the wear amount is relatively large, which will cause changes in the positioning accuracy of the eccentric sleeves. When adjusting the eccentricity of the eccentric sleeves, it is difficult to accurately adjust the eccentricity, and small deviations will have a great impact on subsequent use, and they cannot well meet the usage requirements of people. In view of the above situation, technological innovation is carried out on the basis of the existing eccentric sleeves. Summary of the Invention
