Description

Novel bearing dismounting tool

Technical Field

Background

The bearing is a part for fixing and reducing the friction coefficient of load in the mechanical transmission process, is a part with a very important purpose in modern mechanical equipment, and mainly has the function of supporting a mechanical rotating body so as to reduce the friction coefficient of mechanical load of the equipment in the transmission process. The bearing is required to be assembled with the shaft in an interference manner in the installation process, but the bearing needs to be disassembled and replaced after a certain period of use, or the bearing needs to be disassembled frequently in the daily maintenance process, and the bearing cannot be disassembled by a method of heating the bearing due to structural limitation and different thermal expansion amounts of the bearing and the shaft when the bearing is disassembled.

When the bearing is disassembled, firstly, the expansion pipe of the tool is required to penetrate into the shaft hole before being deformed, then the pointed end is inserted into the expansion pipe to drive the expansion pipe to expand, the expansion pipe is fixed on the bearing, and then, a person pulls the straight rod to pull the expansion pipe outwards, so that the bearing can be disassembled. However, when the expansion pipe passes through the bearing shaft hole, as the tool does not have a supporting piece, an operator needs to hold the tool, the operation is troublesome and laborious when the expansion pipe is put into the bearing or the bearing is discharged, the expansion pipe is disassembled in a pulling mode, sliding is easy to occur during pulling, the hand is easy to slide away from the tool, and the disassembling error rate is high.
