Description

technical field

[0001] The invention relates to a device for pulling out an inner hole sleeve. Background technique

[0002] In the process of maintaining mechanical equipment, it is often necessary to disassemble bushes, sealing sleeves, bearing outer rings and other components tightly embedded in blind holes, but due to the bushings and sealing sleeves embedded in blind holes 1. The inner end face of the outer ring of the bearing is usually on the inner hole step in the inner hole. It is difficult for the existing various pullers to effectively hook the bushing, sealing sleeve, bearing outer ring embedded in the blind hole. The inner end face of the ring makes it very difficult to disassemble the bushing, sealing sleeve, and bearing outer ring embedded in the blind hole. Contents of the invention

[0003] The purpose of the present invention is to provide an inner hole sleeve lifting device that can efficiently and quickly remove the bushing, sealing sleeve, and bearing...
