Research On New Precision Planetary Transmission Accuracy Of Experimental Tests And Analysis

High performance precision planetary reducer usually has a small volume,large-ratio, high transmission precision small backlash, high efficiency advantages andso on, so it has broad application prospects.This paper comes from the Financial Aid of National Natural Science Foundationof China(50705100). Experiment research and analysis are conducted for a new type offloating plate involute planetary gear reducer and a new type of double crank involuteplanetary gear reducer The main contents include the following:①This paper introduces the work principle, structure, design parameters andperformance parameters of a new type of floating plate involute planetary gear reducerand a new type of double-crank conical involute planetary gear reducer, and aiming atthe structural characteristics and performance parameters of the study, the test bench isdesigned, experimental test methods are drawed up, and data processing program areproposed.②Automatic program-controlled test system which contain motion control ofreducer, test data collection and data preservation is designed, and test software basedon VC is developed; post processing of experimental data is developed by Matlabsoftware.③Experimental test data of transmission error is dealt with by Time-domainspectrum method and spatial domain method, The paper is aimed at their structurecharacteristics and performance parameters of planetary transmission, the results thathave been analyzed and to deal with show that: The transmission error of new type offloating plate involute planetary gear reducer comes mainly from input shaft(swiveling jib) and floating plate, The transmission error new type of double-crankconical involute planetary gear reducer is mainly because of crank.
