Introduction

Mechanical engineering has a leading role among other sectors of the economy, since machines perform the main production processes. Therefore, the technical level of many industries largely determines the level of development of engineering.

Increasing operational and quality indicators, reducing the time for the development and implementation of new machines, improving their reliability and durability are the main tasks of machine builders.

In this course work, a belt conveyor drive was developed, consisting of the following parts: an electric motor, an open cylindrical gear train, a cylindrical planetary two-stage reduction gear, a clutch with an elastic sprocket and an actuator. Consider the purpose and advantages and disadvantages of all components.

The electric motor is designed to convert electric energy into mechanical energy, as well as to provide rated power and rotation speed on the input shaft of the reduction gear box.

Reduction gear is designed to transfer power from electric motor to actuator with increase of torque and decrease of rotation speed. The advantages are simplicity and reliability of the design, high efficiency.

The actuator is a drum assembly.
