Project Details
Description
This project will establish an analysis model for evaluating noise by transmission error within two years, so as to reduce the noise and vibration of the powder metallurgy planetary gear drives during operation. In the research of gear dynamic system, the noise and vibration generated by the transmission are closely related to the transmission error. Therefore, in this project, the signal analysis through noise and vibration measurement as well as the simulated transmission error of the planetary gear mechanism are compared and analyzed, so as to establish a design guideline for improving the transmission performance, which can be an aid to determine the manufacturing tolerance during developing and designing the relevant planetary gear drives.This year's project, the second year's, focuses on noise detection and manufacturing accuracy analysis. The planetary gear mechanism explored is a compound stepped planetary gear speed increaser. Relevant research contents include as follows.A. Planetary gear mechanism transmission noise/vibration measurement and signal analysis. It is mainly used to measure the transmission noise/vibration signal of the planetary gear mechanism with different error settings. The effects of eccentricity of the sun gear and planet gear, backlash and meshing phase on transmission noise/vibration will be explored and discussed.B. Modification of generalized analysis model of multi-stage planetary gear mechanism. By comparing the measurement results with the program simulation results, the analysis model is corrected and the expert system design platform is refined accordingly.C. Manufacture and inspection of test planetary gear mechanisms. The errors of important components of the planetary gear mechanism for testing will be specified, and the design and manufacture of the components of the relevant test gearbox will be completed. After the test gearbox is assembled, the transmission precision will be measured first.The results of this project can also provide other non-powder metallurgy planetary gear drives for simulation and analysis of transmission errors.
