DRIVE DRUM OF A RATTLER WITH AUTO-OSCILLATION INTRACHAMBER LOADING

摘要

The drive drum of a rattler with auto-oscillation intrachamber loading comprises a drive motor, a mechanical transmission and a resilient element. Resilient element is located between mechanical transmission and drum. Value of angular stiffness of the resilient element provides an approximation of circular frequency of natural angular oscillations of loaded drum with a resilient element to the angular velocity of drum rotation in the mode of self-excitation of auto-oscillation of loading.
