The present invention discloses an integrated device of a motor and a planetary
reducer and a manufacturing method thereof, and the technical scheme thereof includes: a casing, a motor
assembly and a planetary
reducer assembly, the casing is provided with mounting cavities for the motor
assembly and the planetary
reducer assembly respectively, the motor assembly and the planetary reducer assembly are matched in transmission, and a cooling structure is provided on the outer circle of the casing. The manufacturing method mainly processes the casing, the
stator core is installed on the casing, the rear end cover of the motor is fixed on the casing, the rotor of the motor is first installed on the front end cover inside the motor, and then pressed into the
stator, the sun gear of the planetary reducer is installed on the
motor shaft, and the gear lubricating oil is added through the planetary
gear oil filling port on the casing, and the
coolant needs to be introduced into the casing during operation. The entire technical scheme has a compact structure, simple transmission, and convenient maintenance, and the
system efficiency, rotation accuracy, position accuracy and service life are greatly improved, and the
heat generation and operating
noise are greatly reduced.
