Research on the Load Sharing Technique and Experimental Validation of NGW Type Planetary Gear Train

In order to solve the problem of load sharing in planetary gear train, the design of planetary gear train was described briefly in this paper. The calculation model of type NGW planetary gear train was established. By analyzing the variety of factors, such as selection of bearing clearance, gear modification, using of flexible structure and the sun gear floating design technology, several ways to improve the load sharing of the planetary gear train techniques were obtained, and they were verified by experiments finally.
