Introduction

The reduction gear is a mechanism included in the drives of the machines and serves to reduce the angular speeds of the driven shaft in order to increase torques.

Gearbox housing accommodates some type of gear fixed on shafts. Shafts rest on bearings located in the housing sockets; rolling bearings are mainly used. In this case, it is necessary to design a single-stage cylindrical reduction gear with a helical gear, for which you need to select an electric motor, calculate the transmission, shafts, keys, select the necessary rolling bearings, and lubricate.

. Cylindrical gears are used to transmit torque between parallel shafts in the reduction gear. They are most often used in technology because of a number of advantages:

1. Compact.

2. Possibility of high capacity transfer.

3. Constant transmission ratio.

4. Use of non-deficient materials.

5. Easy to maintain.

The main requirements for the created mechanism are high productivity, reliability, processability, repairability, economy, minimum dimensions and price. All of the above requirements are taken into account in the design and design process.
