Abstract

In this study, we experimentally tested slide bearings made of modified pressed wood (MPW), showing that a high probability of their failure occurs when the counterbody surface hardness is less than 50 HRC. For the first time, laboratory tests of antifriction properties of MPW bushings with counterbodies having various hardness of the contact surface were performed in order to predict the operating modes of friction units of machines and mechanisms. In experiments according to the “shaft–partial insert” scheme on a 2070 SMT-1 friction machine, 45, 45Kh, and 18KhGT-steel rollers were used as a counterbody. The hardened steel rollers were tempered to low, medium, and high temperatures in order to obtain various hardness of the contact surface. The pressed wood inserts were impregnated with MC-20 mineral aviation oil thickened with a high-molecular additive.
