Research of the Cylindrical Self-Braking Gears Effect on the Drive Operation in Various Modes

Many electromechanical drives require the fixation of the output link in a given position and the prevention of its spontaneous movement under load. To ensure this, the drive is usually equipped with a brake. However, in many cases it is possible to do without a special braking mechanism if a self-braking mechanism (gear) is included in the drive, which combines the functions of transferring motion and automatic braking the drive after the engine is turned off. This solution allows obtaining a simple and compact structure and reducing the cost of the drive by eliminating the brake. Dynamic models of an electromechanical drive with a power unit consisting of an electric motor and a gearbox, that is a cylindrical self-braking gear are considered. The equations of motion of the main system elements are given, which make it possible to assess the frequency and transient characteristics of the drive, the ability of its operation in various modes.
