Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft bearing installation, and in particular relates to an installation tool for aircraft bearings. Background Art

[0002] During the assembly of an aircraft, bearings are used in many places. The traditional way of installing bearings is usually interference fit, that is, hammering them into the installation part with a hammer and removing them with external force. However, on aircraft, the installation positions of many bearings are too narrow to be installed or removed using traditional methods. Operators usually put the bearings into the installation area with their bare hands or using tools such as wrenches and cutters. Therefore, it is impossible to directly observe whether the bearings are aligned during installation, resulting in low installation efficiency. Utility Model Content

[0003] The utility model aims to provide a mounting tool for aircraft bearings, which uses an expansion component to fix the bearings, thereby mounting or dismounting the bearings.
