Embodiment Construction

[0009] As shown in the figure, the bearing installation tool includes a pressure head 1, a guide shaft 2, a spring 3, and a cylindrical pin 4. The guide shaft 2 is installed inside the pressure head 1 and can move axially inside the pressure head 1. One end of the guide shaft 2 is provided with a spring 3 , and the other end of the spring 3 is pressed against the inner wall of the pressure head 1 . The other end of the guide shaft 2 protrudes from the end of the indenter 1, the outer diameter of the part of the guide shaft 2 protruding from the indenter 1 is equal to the hollow inner diameter of the shaft where the bearing is installed, and the inner diameter of the indenter 1 is equal to the installed bearing The outside diameter of the shaft is a clearance fit. The indenter 1 is also provided with a symmetrical axial waist-shaped through groove, and the guide shaft 2 is provided with a pin 4. After the pin 4 protrudes from the guide shaft 2, it is located in the waist-shaped...

Abstract

The invention relates to a bearing mounting tool with a centering function; the bearing mounting tool comprises a pressure head (1), a guide shaft (2) and a spring (3); the guide shaft (2) is installed inside the pressure head and is capable of moving axially inside the pressure head (1); the spring (3) is arranged at one end of the guide shaft (2); the other end of the spring (3) is pressed against the internal wall of the pressure head (1); the other end of the guide shaft (2) is capable of being stretched out of the end part of the pressure head (1); the external diameter of the part of the guide shaft (2) stretched out of the pressure head (1) is equal to the internal diameter of the hollow part of a shaft equipped with a bearing; and the internal diameter of the pressure head (1) matches with the external diameter clearance of the shaft to be mounted with the bearing. The centering function during installation is realized; no deflection of the bearing during installation is guaranteed and the requirement without damaging the bearing, the shaft and the bearing seat is satisfied.

Description

technical field [0001] The invention relates to a bearing installation tool, in particular to a bearing installation tool with a centering function, which is used for installing a bearing on a hollow shaft through an interference fit. Background technique [0002] During the use of bearings, in order to ensure the reliability of use, generally the inner ring of the bearing and the shaft and the outer ring and the bearing seat are installed by interference fit. Therefore, a lot of pressure is required during the installation process to make the bearing The bearings are in place. However, it is difficult to ensure that the bearing is installed without deflection when pressing the inner or outer ring. If deflection occurs during installation, it will seriously damage the bearing, shaft and housing. Therefore, it is very important to center the bearing correctly and ensure the correct position of the bearing during installation. Contents of the invention [0003] The purpose...
