FIELD: obtaining translational motion of transport facilities. SUBSTANCE: inertial force constantly directed along axis of motion of transport facility is created due to mounting 2n unbalance vibrators on common rigid axle at distance L from each other and angle of shift of instantaneous force phases created by vibrators is equal to Φ=-πL (i - 1)/τ, where L= t k/n, τ = V/2f is pole pressure; f = w/2π is frequency of vibrations of vibratory force; i is ordinal number of debalance vibrator; n is number of pairs of vibrators; V is preset speed of motion of inertial force; w is angular frequency of rotation of vibrators; k is integral number which is even for odd "n" and odd for even "n". To ensure required stopping distance and braking, angle of phase shift of instantaneous forces created by vibrators shall be changed. Provision is made for change of maximum speed of motion of inertial force due to change of distance between vibrators. Device is provided with movable spring-loaded eccentrics; during rotation of vibrators, eccentrics shift off center due to centrifugal forces smoothly increasing vibratory force in starting. EFFECT: enhanced efficiency and reliability; wide range of adjusting speed and reduction of vibration. 6 cl, 10 dwg |
