Abstract

The invention discloses an engine bearing bush mounting and dismounting tooling, belonging to the field of engine assembly. The engine bearing bush mounting and dismounting tooling comprises a tooling body, two ends of which are respectively a dismounting end and an mounting end, and the mounting end includes guides in a direction away from the dismounting end in turn. The journal and the bearing bush are matched with the journal, and the diameter of the guide journal is larger than that of the bearing bush and the journal. On the thrust surface of the bearing bush, the guide ring can be hooped on the outer circumference of the two half-tiles, which can provide radial limit to the bearing bush during the installation process to prevent radial deformation or radial displacement of the two half-tiles, and the guide ring can During the press-fitting process, it moves axially along the guide journal to play an axial limit on the installation of the bearing bush and determine the pressing amount of the bearing bush into the bearing seat. The engine bearing bush installation and disassembly tooling structure is simple, the manufacturing cost is low, and the assembly accuracy is easy to ensure.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to an engine bearing bush mounting and dismounting tool. Background technique [0002] Most of the connecting rod big end and the main bearing seat hole in modern high-speed multi-cylinder engines are split structures, that is, the bearing cover can be disassembled. This structure does not require tooling when installing the bearing shell, and the bearing cover can be directly tightened with bolts. In a special-purpose engine such as a single-cylinder testing machine, the main bearing hole or other bearing holes have an integrated structure without a main bearing cover, and the bearing pad is not a circular bushing, but is divided into two half-tiles. When installing the bearing pad, it is necessary to cool the bearing pad or use a tool to press the bearing pad into the bearing hole. The specific process selection should be determined according to the bearing pad material. ...
