The invention relates to the technical field of speed reducers, and provides a low-noise planetary gear reducer. The low-noise planetary gear reducer comprises a motor and a first-stage gear connectedwith an output shaft of the motor, a first connecting part is arranged on the outer surface of the output shaft, the first-stage gear is provided with an inner cavity used for being matched with andsleeving the output shaft, and the inner cavity is provided with a second connecting part used for being cooperatively meshed with the first connecting part. According to the planetary gear reducer, the structure, integrating a first-stage gear with a motor shaft in a high-speed stage, of a planetary gear reducer in the prior art is changed into a split type. Through the mode that the first connecting part of the outer surface of the output shaft of the motor is meshed with the second connecting part of the inner cavity of the first-stage gear, connection between the first-stage gear and the motor is supported, so that vibration and noise caused by the first-stage gear during high-speed operation of the motor can be reduced; and through the split type structure, the first-stage gear can beconveniently replaced when damaged, the design is reasonable, and the planetary gear reducer is practical and convenient to use.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular to a low-noise planetary gear reducer. Background technique [0002] A general planetary gear reducer is equipped with multiple sun gears to connect the planetary flange in the planetary gear box with the output shaft of the motor. One, the main source of the noise of the planetary gear reducer is the vibration of the first-stage gear, and after the first-stage gear is damaged, it is more troublesome to replace. Therefore, how to design a motor connection structure of a planetary gear reducer that can reduce the noise of the planetary gear reducer and can easily replace the primary gear is a technical problem that needs to be solved urgently in the industry. Contents of the invention [0003] In view of the above problems, the present invention provides a low-noise planetary gear reducer. [0004] The object of the present invention adopts following technical scheme to realize:...
