On the Dynamics of an Enhanced Coaxial Inertial Exciter for Vibratory Machines

Theoretical investigations into the capabilities of a coaxial inertial drive with various operating modes for vibratory conveyors and screens are conducted in paper. The exciter is designed one asynchronous electric motor kinematically synchronized rotation two unbalanced masses. Three variants angular speeds ratios, namely ω2/ω1 = 1, –1, 2, considered. Based on these relations, circular, elliptical, complex motion trajectories working members implemented. In first cases, single-frequency harmonic oscillations take place. latter case, double-frequency periodic excited. dynamic behavior motor’s shaft during its running-up running-out influence parameters rotors relative phase shift angle between them elliptical system’s mass center investigated. use forced kinematic synchronization provides stability system all considered regimes.
