Problems solved by technology

There are many factors that affect seal leakage. Among them, it is very important to ensure that the cup is pressed against, the internal skeleton of the cup is not deformed during the press-fitting process, and it is concentric with the mounting seat after press-fitting, because for aviation products, seal leakage will cause engine damage. Test run failure, repeated troubleshooting and test run will cause significant economic losses

The press fitting device is provided with the positioning mechanismand the limit mechanism, leather cup limit press fitting can be achieved, it is guaranteed that a leather cup is concentric with a mounting base after press abutting and press fitting, a leather cup leakage fault caused by improper press fitting is avoided, and normal working of a transmission system is guaranteed.

Description

[0001] This application claims the priority of the earlier application with application number 201910622617.X. technical field [0002] The invention belongs to the technical field of process tooling, and in particular relates to a special press-fitting device for a transmission system leather cup seal, in particular to a press-fitting device with a frame and a spring-type leather cup seal. Background technique [0003] In aero-engine transmission system products, a leather cup is often used to seal the inner cavity of the transmission system. The leather cup is a spring-type oil seal with a skeleton. The schematic diagram of its structure is shown in figure 1 shown. In the process of use, the leather cup leakage failure often occurs. There are many factors that affect seal leakage. Among them, it is very important to ensure that the cup is pressed against, the internal skeleton of the cup is not deformed during the press-fitting process, and it is concentric with the mount...
