Propeller assembly manufacturing method

1. This technology relates to the field of marine equipment, in particular to a propeller assembly.

Background technique:

2. In the motor of the existing propeller assembly, two sets of bearings are usually arranged between the front cover of the motor and the rear cover of the motor to support the output shaft, so as to realize the normal operation of the motor. In some solutions, the bearing chambers are arranged in the front and rear end covers, and the coaxial arrangement of the two bearing chambers is realized by the mutual cooperation of the flanged parts of the front and rear end covers. There are also some motors whose stators directly use interference fit with the motor front cover or the motor rear cover, and the motor rear cover or the motor front cover and the stator adopt a clearance fit and then are fixed by fasteners. Since the front cover of the motor or the rear cover of the motor are matched with the stator, the coaxiality of the front and rear bearing chambers may be poor. The above two situations may increase the difficulty of assembly on the one hand, but also make the assembly accuracy of the motor worse, which further affects the performance, work efficiency and service life of the motor.
