Abstract—The repair of agricultural machines and its gearing drives is a an important challenge. Normally, a wide range of machine tools are required for gear replacement manufacturing, which is hard to provide at repair shops of farm garages. The way to temporary replace broken metal gear for 3d printed polymeric one is proposed. The usage of Novikov gearings and arch-tooth gearing instead of traditional involute cylindrical gears is offered. Estimation of accuracy of such a gearing is offered and results of experimental evaluation are given.
