Vibration and Noise Reduction of a Double Crank Four Ring-Plate-Type Cycloid Speed Reducer

A double crank four ring-plate-type cycloid speed reducer is a new type speed reducer.However,the speed reducer generates large noise and vibration which prevent its popularization and application to some extent.The noise and vibration tests of the double crank ring-plate-type cycloid speed reducer driven by three gears were completed using the Artemis integrated multi-channel noise and vibration analysis system.The vibration and noise characteristics of the speed reducer main parts at different rotational speeds and different loads were analyzed.The main noise source in the speed reducer was identified as the noise caused by the mesh of the cycloid gear and pin wheels.The relevant noise and vibration reduction measures were proposed for the noise source and the speed reducer box.The improved speed reducer was tested and analyzed.The results show that the vibration and noise reduction are achieved effectively through the structural improvements of the box and the ratio changes of the cycloid gear and pin wheels.The conclusions provide the basis for further design of vibration and noise reduction.
