THEORETICAL STUDIES AND CONDITIONS ANALYSIS OF THE INERTIAL SLIDER SLIPPAGE OF ASYMMETRIC PLANETARY VIBRATION EXCITER FOR SNOWPLOW

Abstract

Planetary vibration exciters, including their non-standard versions, are increasingly being used as a pulse generator in modern utility machines. The article describes the workflow of a promising, but little studied planetary vibration exciter with an offset (asymmetric) drive carrier axis from the driven treadmill center used to generate a directional driving force during rotation of the inertial slider. The force analysis was carried out, the reactions of the reactive forces acting on the inertial slider from the carrier and the treadmill were determined. A method has been developed for determining the critical slip angles of an inertial slider along the surface of a treadmill, which makes it possible to rationally select the design parameters of a planetary vibration exciter. A theoretical model of an asymmetric planetary vibration exciter with a pendulum anti-skid device, which adequately describes the dependence of the integral driving force on the initial parameters of the vibration exciter, is obtained. The boundary values are determined at which the slipping and skid of the slider over the treadmill surface will take place, as well as the values of the current rotation angle of the carrier, determining the boundaries of the slider skidding area, which is important for an integrated assessment of the drive torque of the vibration exciter.
