Abstract

In this paper, we consider the movement of abrasive particles located in the wedge-shaped gap of gear teeth. These particles penetrate into the wedge-shaped gap between friction surfaces. In the event that the friction force between the abrasive particle and the friction surfaces is greater than the forces that prevent the penetration of the abrasive particle, which arises from the normal force, the abrasive particles are pressed against the friction surfaces. It was found that the largest size of abrasive particles that penetrate into the wedge-shaped gap of the gear teeth with an increase in the friction coefficient from 0.01 to 0.07 increases by more than 20 times while an increase in the meshing modulus from 0.001 to 0.025 m doubles in the presence of lubrication. It is proposed to consider the wear of gears as a process that occurs with the active and passive participation of abrasive particles. The wear of the gear teeth with the active participation of abrasive particles occurs in the wedge-shaped gap between the gear teeth at the frictional force of the surfaces before they are crushed. Wear with the passive participation of abrasive particles occurs in the contact zone of the gear teeth after crushing of abrasive particles due to the force interaction of the protrusions of the roughness of the friction surfaces.

渗透到齿轮齿楔形间隙中的磨料颗粒的尺寸确定

摘要

在本文中，我们考虑了位于齿轮齿楔形间隙中的磨料颗粒的运动。这些颗粒渗透到摩擦表面之间的楔形间隙中。如果磨料颗粒和摩擦表面之间的摩擦力大于阻止磨料颗粒渗透的力（由于法向力而产生），则将磨料颗粒压在摩擦表面上。已发现，随着摩擦系数从0.01增至0.07，最大尺寸的磨料进入齿轮齿的楔形间隙中会增大20倍以上，而啮合模数从0.001增至0.025。在润滑的情况下，m增加一倍。提出将齿轮的磨损考虑为磨料颗粒的主动和被动参与所发生的过程。在磨齿被磨碎之前，在磨齿之间的楔形间隙中，在磨齿的主动力作用下，磨齿的磨损发生在磨齿之间的楔形间隙中。由于摩擦表面的粗糙度的突起的力相互作用，在磨料颗粒被压碎之后，在齿轮齿的接触区域中发生磨料颗粒的被动参与磨损。
