Problems solved by technology

[0002] At present, in order to reduce the overall size of the existing deceleration motors on the market, the deceleration mechanism and the motor assembly are arranged in the same cabin. Due to the limited heat dissipation conditions of the motor assembly, the heat of the motor assembly cannot be dissipated quickly. There is a greater risk of burning
At the same time, the transmission of the temperature rise of the motor assembly to the reduction mechanism will accelerate the aging speed of grease, lubricating oil and gears, resulting in the problems of easy failure of lubrication, high transmission noise and high maintenance costs
In addition, since the deceleration mechanism and the motor assembly are in the same cabin, there is also the problem that the lubricating oil easily invades the motor assembly, resulting in electric leakage and easy damage to the motor assembly

Abstract

The invention provides a gear motor. The gear motor comprises a shell, a motor shaft, a motor assembly and a gear reduction mechanism, wherein a first installation cavity, a second installation cavityand an installation hole for communicating the first installation cavity and the second installation cavity are arranged in the shell; the motor shaft is arranged in the installation hole in a sleeved mode, at least one end of the motor shaft extends out of the shell, and the motor shaft and the shell can rotate relative to each other; the motor assembly is arranged in the first installation cavity, the motor assembly comprises a stator winding assembly and a rotor assembly, wherein the stator winding assembly is fixed on a motor shaft, and the rotor assembly is arranged outside the stator winding assembly in a sleeved mode; the gear reduction mechanism is arranged in the second installation cavity, the input end of the gear reduction mechanism penetrates through the installation hole andis connected to the rotor assembly, and the output end of the gear reduction mechanism is connected to the shell. According to the technical scheme, the motor assembly and the gear reduction mechanism are not prone to influence each other, so that the accelerated aging of the gear reduction mechanism is not easily caused due to the fact that the temperature rise of the motor assembly is too high,and the situation that lubricating oil on the gear reduction mechanism intrudes into the motor assembly is avoided.

Description

technical field [0001] The invention relates to the field of motors, in particular to a geared motor. Background technique [0002] At present, in order to reduce the overall size of the existing deceleration motors on the market, the deceleration mechanism and the motor assembly are arranged in the same cabin. Due to the limited heat dissipation conditions of the motor assembly, the heat of the motor assembly cannot be dissipated quickly. There is a greater risk of burning. At the same time, the temperature rise of the motor assembly transmitted to the reduction mechanism will accelerate the aging speed of grease, lubricating oil and gears, resulting in the problems of easy lubrication failure, large transmission noise and high maintenance costs. In addition, since the deceleration mechanism and the motor assembly are in the same cabin, there is also the problem that lubricating oil can easily invade the motor assembly, resulting in electric leakage and easy damage to the ...
