Investigation of the process of excitation of dual-frequency vibrations by ball auto-balancer of GIL 42 screen

Influence of elasticity of unbalance drive in vibration machines on its oscillations

“…Among the recent works, which consider the problems of start-up of vibration machines with inertial drive, the papers [13][14][15][16][17] should be noted. In [13][14][15], the practical application of the Sommerfeld effect is substantiated. In [16], resonant oscillations in a limited-excitation system, where there is an interaction between the power source and the elastic subsystem, which may lead to large resonant oscillations are considered.…”

Research into excitation of dual frequency vibrational-rotational vibrations of screen duct by ball-type auto-balancer

“…In the paper [12], the applicability of method for the modernization of the industrial screens was proved. For this, the 3D model of the light type screen GIL 42 with the single-frequency inertia vibration exciter and the twofrequency vibration exciter in the form of a ball auto-balancer was developed.…”

Research by a 3D modelling of the screen box flat translatory vibrations excited by a ball auto-balancer

“…In work [6], proofs are provided on the operability of the method of a translational rectilinear motion of the screen box, and in work [7] -of a vibration rotation. The possibility of changing the characteristics of dual-frequency vibrations is confirmed for broad ranges.…”

“…The form and rotor unbalance of the flexible rotor depend on the current velocity of rotation, change from temperature, wear of the rotor and so forth. Therefore, the balance of such rotors during operation is worthwhile to be constantly corrected by passive auto-balancers [3][4][5][6][7][8][9][10][11][12][13]. In the latter corrective weights (pendulums, balls or rollers) under certain conditions come to positions in which they counterbalance the rotor.…”
