Introduction

Reduction gear is a mechanism used to reduce rotation speed and increase torque. Reduction gear, complete mechanism connected to motor and working machine by coupling or other detachable devices. The reduction gear consists of a body (cast iron or steel welded). Gear or worm gears fixed on shafts are arranged in reduction gear case. Shafts rest on bearings located in housing sockets; rolling bearings are mainly used. The type of reduction gear is determined by the composition of the gears, the order of their placement in the direction from the high-speed shaft to the slow-speed shaft and the position of the axes of the gear wheels in space.

The purpose of the reduction gear is to reduce the angular speed and increase the torque of the driven shaft compared to the driving shaft. The gearing principle is based on the engagement of a pair of gears. The advantage of gears is: high efficiency, constant gear ratio and a wide range of powers.

In this design, a mechanical drive opened by a cylindrical helical transmission was calculated.
