NUMERICAL CALCULATION OF THE MULTIPARA CONVEX-CONCAVE PRECESSION GEAR

Stanislav LEALIN, Dumitru VENGHER

Abstract


In modern methods of calculating the maximum allowable loads on precision gear reducers, computer simulations are increasingly being used. In this paper, the moments/loads limits on the precision gear reducer and the multi-pair convex-concave precessional gearing in it will be calculated. The theoretical calculation of the maximum allowable moment on the satellite with multiple gearing will be performed using the calculation formulas given in reference. At the same time, three pairs of teeth on one side of the satellite and three pairs on the opposite side are engaged in the gearing. The forces between them are equalized. The modeling will be done based on a special module for calculation and analysis of complex structures using the integrated Stress Analysis module (Autodesk Inventor Professional 2022 software). It utilizes finite element analysis based on the ANSYS software. Furthermore, it has been compared both calculations and examine the load distribution overall on all gearbox components. It has been considered the most heavily loaded areas and, if necessary, provide solutions. It has been optimized individual components and increase the size of some bearings to achieve the optimal possible load on the gearbox.
