The paper addresses the urgent task of improving the design of a single-shaft unbalanced vibration drive for vibration machines used in modern mechanical engineering to intensify processes of mechanical treatment of parts. The proposed structural solution provides the possibility of remote and automated adjustment of the oscillation amplitude of the working body by changing the relative angle between the unbalances mounted on the drive shaft. The use of an industrial microcontroller enables the tuning of vibration treatment modes both before the start of a technological operation and directly during the working cycle, which significantly increases the flexibility and efficiency of the process.
The current research shows that the effectiveness of vibration treatment is determined by a complex of parameters - amplitude, frequency, and oscillation form, as well as the characteristics of the parts and the working medium. Traditional unbalanced drives have limited adjustment capabilities, which reduces surface quality and shortens equipment service life. The proposed design eliminates these drawbacks through the use of an electromagnetic actuator and a stepper engine, which ensure precise positioning of the movable unbalances and stabilization of the oscillation amplitude. This allows maintaining optimal technological regimes, avoiding overloads, and ensuring high surface quality even for parts with complex configurations.
The implementation of the developed solution into the design of the vibration exciter opens up opportunities for creating a new generation of vibration machines with automated control of process parameters. Such an approach contributes to increased energy efficiency, expanded technological capabilities of equipment, and provides prospects for its use in multipurpose production complexes. The findings of the study can be applied both to update existing machines and to develop new samples of vibration technology with improved technical and economic indicators.
