Abstract:	研究期間：10108~10207;Besides the dynamic analysis, static load analysis of planetary gear drives is an essential and fundamental research issue for designing high power transmission. Especially the problem of the loads in the multiple gear pairs of planetary gear sets must be analyzed to solve the load sharing among the planets, the load distribution on flanks and also the flank modification so as to avoid concentrated stress on the flanks. A new LTCA approach for multiple gear-pairs of planetary gear drives will be thus intensively studied in the three-year project based on the research results from the loaded tooth contact analysis (LTCA) of conical gears in the past years. A load analysis model for planetary gear drives will be developed and also validated numerically by FEM and experimentally by conducting load test on a test rig. This proposal belongs to the second and the third year of the project. The main research topics are summarized, (a) Analysis approach for load sharing and load distribution: will be developed based on the loaded tooth contact analysis of the multiple tooth-pairs to analyze the load sharing among the planets and the load distribution on the engaged flanks under consideration of the presentence of errors due to assembly, manufacturing and deformation of the components. Planetary gear drives with two kinds of load balance mechanisms, i.e. floating sun gear and flexible pin, as well as the influences of the errors on the load conditions are also analyzed. The analysis results are also compared with FEM. (b) Experimental validation：A test rig and two different types of test planetary gear sets will be also constructed for a validation experiment. The proposed analysis approach will be validated experimentally by measuring the variation of loads among the gears and along the engaged flanks under loading and also by conducting a fatigue test for reliability. The results of the project will be an aid for further development of planetary gear drives for high power transmission.
