Finite Element Analysis of Gear Pair of Main Drive Gearbox Based on Workover Treatment

Abstract:

Considering the fact that the oil well conditions of LIAOHE oil field, the existing structure of the forced lifting and pushing system of work over rig is improved. Main drive gear pair of the forced lifting and pushing system improved is established to study the intensity of contact and modal in the operating process and the dynamic loads based on finite element method. Main failure forms in the condition of low speed and heavy duty is deduced from the distribution of the stress. Also, the maximum allowable stress and natural frequency is obtained. According to the simulation making use of ANSYS, a 3D contact stress analysis of several teeth and modal analysis in dynamic pre-stress of full teeth is illustrated with the rationality of the design.
