The power input end of the air compressor crankshaft is connected to an air compressor flywheel. An air compressor flywheel housing is fixedly provided on the air compressor crankcase, and the air compressor flywheel is arranged in the air compressor flywheel housing.

[0004] For example, the power is transmitted between the main shafts of the existing air compressor and the diesel engine mentioned above through a coupling. During the specific implementation process, due to the poor integration of the diesel engine and the air compressor, the different frequency movements of the diesel engine and the air compressor can easily cause deformation or even damage to the coupling. Therefore, it is urgent to propose a corresponding coupling alignment device to solve the above problems. Utility Model Content
