The paper considers the gear transmission of a two-stage gear reducer, calculates its geometric parameters and develops a gearbox drawing. The results of calculations in the program APM WinMachine showed that the effective contact stresses on the pinion and wheel are equal to the permissible ones, which is the reason for the small transmission resource of 384 hours due to the lack of a safety margin. To increase the durability of the gear transmission, suggested replacing of the material of the gear and wheels Steel 45 with structural alloy Steel 20CrN. Due to the replacement of the material, it is necessary to change the heat treatment "Improvement" to saturation of the surface with carbon "Cementation". The measures taken increase the resource of the gear transmission to unlimited.
