The power train of reducer for driving cutter head device of tunnel boring machine makes use of 3-stage complex planetary gear system. The complex planetary gears are very important parts of reducer for tunnel boring machine because of strength problem. In the present study, calculating the specifications of the complex planetary gears and analyzing the gear bending and compressive stresses of the planetary gears, it is necessary to analyze gear bending and compressive stresses confidently for optimal design of the complex planetary gears in respect of cost and reliability. In this paper, analyze actual gear bending and compressive stresses analysis of the planetary gear system using Lewes & Hertz equation and verifying the calculated specifications of the complex planetary gears by evaluating the results with the data of allowable bending and compressive stress from the Stress - No. of cycles curves of gears are equally significant.
