Abstract
The question of cargo gravity center and its modules with positive and negative values of external forces influence on the operation of roller carriages and their rolling bearings in monorail carriages is considered, and the dynamic, plane-parallel motion of roller carriages and their rolling bearings in monorail carriages. The work of bearings can be represented as a ball rolling on a flat surface, constructing schemes for the impact of external and internal forces on the ball and the plane on the rolling motion. It is proved that there is no external forces acting on the ball with a positive value, where the negative value of the external forces is determined by the presence of a hollow ball without an internal positive Hertzian pressure in the current scheme of cargo movement on the suspended monorail transport and there is a negative Hertzian pressure, which results in colossal wear of the bearings, with a “minus” sign according to the Dang Vann criterion along the Z axis and tendency to the minimum value, to zero along the XY axes of the main plane. There is a movement of drawing and there is no rolling motion, there are processes of destruction of bearings and plowing of the main plane on which the ball is located, irrational operating costs.In the proposed innovative method, there is the presence of internal Hertzian pressure and the ball contact pressure points, the presence of rolling motion and the effect of the load gravity center and its modules on the bearings operation. This method is more efficient and safe for work. A new way of slinging and moving cargo in the mine workings is analyzed on the comparative basis of the current scheme of cargo movement in strict accordance with the general laws of mechanics, where the forces are formed in such a way that the rolling takes place, and the support bearing balls on the axles work as a support due to two cargo modules included in operation and the cargo lifting and movement method influence at the suspended monorail transport.
