Introduction

The purpose of this project is to design a chain conveyor drive with a conical-cylindrical reduction gear.

Components of the drive are: electric motor, conical - cylindrical reduction gear, 2 elastic couplings, drive shaft.

The drive operates as follows: torque is transmitted from the electric motor through an elastic clutch to the input shaft of the reduction gear box; from output shaft of reduction gear box through elastic clutch to drive shaft.

You need to perform the necessary calculations, select the best diagram parameters and develop design documentation for the manufacture of the drive:

• gearbox general view drawing (at sketched design stage);

• gearbox assembly drawing (at technical design stage);

• working drawings of gear box parts;

• general view drawing of the drive;

• calculation and explanatory note and specifications;
