Description

Technical Field

[0001] This utility model relates to the field of compressor manufacturing technology, and in particular to a compressor cylinder bearing pressure bearing tooling. Background Technology

[0002] In current compressor manufacturing processes, bearings are assembled by directly placing them onto the bearing positions in the compressor cylinder and then pressing them in using a press. While this assembly method is simple, it has the following drawbacks: Due to the lack of precise guiding and limiting mechanisms, the bearings are prone to misalignment during press pressure application, resulting in insufficient fit between the bearing and the cylinder bearing position. This affects the concentricity of the compressor during operation, leading to increased compressor vibration, noise, and reduced overall compressor performance. Furthermore, if the bearing is misaligned, the hard compression between the bearing and the cylinder can easily generate aluminum shavings. These shavings, once inside the compressor, not only contaminate the lubricating oil and accelerate component wear but may also clog oil or air passages, affecting the compressor's sealing and cleanliness, and in severe cases, even causing compressor malfunction and shutdown.
