Design and Finite-Element Analysis on Double-Circular-Arc Gear of the Turbodrill Reducer

Abstract:

The double-circular-arc gear bearing capacity is the key problems for realizing the low speed and high torque work demands of small-diameter deep-well turbodrill reducer. Double double-arc gear shaft structure is adopted for improving the gear bearing capacity Based on the 2K-H-NGW type planetary gear transmission. Increase modulus and decrease teeth number properly can improve the double-circular-arc gear capacity on the premise of limited radial size. This article analyze the gear bending stress based on ANSYS and simulation results show that stress mainly concentrated on tooth root and tooth waist area and maximum loading is at tooth waist area. The simulation maximum bending stress is 289N/mm2 and the theoretical bending stress is 277.50N/mm2.The two results are basically identical. It is consistent with the actual work situation.
