In the task for this course design, a diagram of a belt conveyor with a tensioner, as well as a diagram of a drive station to it, is given. Drive station includes electric motor, worm reduction gear and mounting platform. In this case, a welded frame will be used as the platform.

The electric motor is attached directly to the reduction gear, this reduces the size of the station and its metal capacity.

The requirement lists the main technical characteristics: circumferential force on the drum, conveyor belt speed, load schedule, service life, which must be ensured during design.

Belt conveyors are very common transporting machines used in various fields of the national economy to move a variety of piece and bulk cargoes.

Belt conveyors were widely used for interoperative transportation of goods in in-line production, for transportation for linear purposes (supply of land), in mining, for supplying fuel and grain to an elevator, etc.

Belt conveyors are distinguished by high performance, simplicity of design, low weight, reliability in operation, and relatively low energy consumption.
