The Effect of Diameter in Soil-Tilling Cutter with Vertical Rotation Axis on the Resistance Moment Resulted from Soil Cutting

Abstract

The article considers the effect of the diameter in the soil-tilling cutter with vertical rotation axis on the energy intensity of the technological process. By the analysis the approach of G.F. Popov has been approved according to which the dependence of the cutter’s rotation moment (torque) on its diameter varies due to the regularities of the second-order curve.  We believe that upon the constant cutter supply the growth of torque with increasing diameter is accounted for absolute knife speed, cutting force of the soil, as well as for the increase in the length of cutting trajectory. If the kinematic parameter of the rotary machine stays constant, then the increase in the thickness of cutting soil slice supplements the above mentioned reasons.
