Abstract

The invention is a vibration exciter with adjustable eccentric mass, which includes a frame, a protective cover installed on the frame, a water tank fixed at the middle position of the bottom of the frame, a biaxial motor installed on the frame, and a controller. Sleeves are installed at the ends of the two output shafts of the biaxial motor; there is a piston in the sleeve, and a screw is fixed on the piston; the screw matches the screw nut through the thread pair; the screw nut is installed on the large gear and passes through The bearing is installed on the bearing seat; the bearing seat is fixed on the sleeve; the motor is installed on the sleeve; the pinion gear is installed on the shaft of the motor; the pinion gear meshes with the large gear. The sleeve connected to the water tank serves as the rotating part of the vibration exciter. Through the movement of the piston in the sleeve, the mass of the liquid in the sleeve is changed, thereby adjusting the vibration eccentric mass.

Description

technical field [0001] The invention belongs to the technical field of vibration testing, in particular to a rotary vibrator with adjustable eccentric mass. Background technique [0002] With the continuous development of my country's science and technology, high-end mechanical equipment, such as large compressors, aero-engines, gas turbines, high-end CNC machine tools, high-speed trains, large-scale construction machinery equipment, surface ships, deep-water submarines, etc., are mostly in a continuous working state. In the process of operation, and the working speed of these equipment and its key parts and components is getting higher and higher, the structure is becoming more and more complex, the structural components are becoming more and more precise, the precision is getting higher, and the functions are more and more complete. In terms of reliability and safety, the demand for external and self-vibration suppression is becoming more and more urgent. [0003] In the pr...
