Embodiment Construction

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0055] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0056] Such as Figure 1-22 As shown, the present invention provides a motor-driven reducer. The drive motor is decelerated by the reducer to drive the compressor to run. The present invention mainly improves the reducer so that the reduction ratio can be selected, thereby facilitating the adjustment of compression The operating compression ratio of the air conditioner, combined with the operating control of the drive motor, improves and optimizes the output performance of the air conditioning system.

[0057] Specifically, the input end of the reducer is connected to the drive ...

Abstract

The invention discloses a reducer for motor drive system, which comprises a first speed reducer and a second speed reducer. The input end of the first speed reducer is connected to the drive motor shaft, and the input end of the second speed reducer is connected to the first speed reducer. A through hole is opened in the rotating shaft, and a second gear column is disposed at the center of the inner ring gear. The second gear column is divided into a first single shaft and a second single shaft that are rotationally connected; a sun gear set is disposed on the second single shaft and each gungear is axially moved with the second gear column at the same time. The first sun gear, the first following gear, the outer side wall of the second following gear, and the outer side wall of the two planetary gears are selectively engaged. The invention solves the technical problem that the electric compressor has insufficient regulation performance on the air conditioning system.

Description

technical field [0001] The invention relates to the technical field of compressors, and more specifically, the invention relates to a reducer for motor driving. Background technique [0002] The air conditioner compressor plays the role of compressing and driving refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and then sends it to the high-pressure area for cooling and condensation. The heat is released into the air through the heat sink, and the refrigerant also changes from gaseous to liquid, and the pressure increases. [0003] The compression ratio of the existing compressor is not easy to control, which makes it more difficult to control the temperature of the air conditioner. Especially for electric compressors, the motor drives the compressor to run, and the speed of the motor directly a...
