轴承拆卸工装

Abstract

本实用新型属于工装技术领域，公开了一种轴承拆卸工装，包括底座、驱动轴、拆拉组件和推顶套，驱动轴的一端可转动地连接于底座上，驱动轴的另一端用于与主轴背离主机的一端抵接，驱动轴设有旋向相反的第一螺纹段和第二螺纹段，拆拉组件螺纹连接于第一螺纹段上，并用于与轴承连接，推顶套连接于第二螺纹段上，并用于抵接在紧定套背离主机的端面上。使得当进行轴承拆卸作业时，通过旋转驱动轴，从而使轴承与紧定套受到相反的作用力，即可将轴承与紧定套分离，既实现轴承的单独拆卸，又提高了拆卸轴承时的便捷性，并且由于轴承与紧定套沿相反的方向移动，减少了紧定套在拆卸时发生位移的距离，从而改善了在拆卸时紧定套对于主轴的损伤。
