When modeling gears by means of roller analogues it is necessary to take into account that the degree of slippage is equal to zero in the meshing pole of the gears, in thecontact zone ofinitial circles of the gears. The greatest slippage occurs between the tooth head of the master gear and the tooth foot of the driven gear, and between the tooth head of the driven gear and the tooth foot of the driven gear. Thus, the simulation of the wear process of gear wheels with roller counterparts is achieved by ensuring equality of geometric and kinematic parameters (radii of contact point curvature, degree of relative slippage of the surfaces, friction paths) and contact pressure.

The paper considers the use of soft containers (MCs) for transporting vegetables, particularly root crops. Until recently, MCs, simply put bags, were used in agriculture to transport goods weighing up to 100 kg. As the proportion of mechanisation is increasing, the use of MCs in larger sizes is becoming more and more important. This article examines the wall pressure of small and large-sized MCs and compares it to the strength of polypropylene fabric. As a result of calculation of pressure on walls of MK it is shown possibility of use of polypropylene PP cloth of various density.
