The purpose of the project is to develop a drive to a chain suspension conveyor.

During the work on the project, an electric motor was selected, the kinematic and power calculation of the drive was carried out, the calculation of gear gears, gear shafts, the design sizes of gear wheels and the housing were determined, bearings were selected and checked for durability, the strength of key connections was checked, and the lubrication of gear gears and bearings was selected.

As a result of the work, the following were developed: a gearbox assembly drawing, working drawings of gearbox parts, a general view of the drive.
