    摘要: Method of testing the lubricating properties of the lubricating means consisting in that in a test master rubbing pair, operating at a definite temperature and with definite unit pressures, or at a definite temperature and with a definite rubbing speed, at the presence of the lubricating means being tested, either the slip rates are gradually decreased in a linear way, or the unit pressures are gradually increased also in a linear way and, at the same time, parameters characterizing these properties are recorded. The rubbing speed is gradually decreased down to a minimum limit value, or the unit pressures are gradually increased to a definite maximum limit value corresponding to a condition, when the electric resistance and the friction force attain the values characteristic for the dry friction.In the device according to the invention the rotary test piece (1) is mounted on a shaft of an electric motor (2). Two counter-specimens are mounted in holders (5) accommodated in the insulating guideways (6) mounted in the device body (7), the said device consisting of an inner chamber (8) containing the lubricating means to be tested (9) and of an outer chamber (11) containing the thermostatic liquid (12). The motor housing (2) is connected to the body (7) by means of a ball bearing (13) and a spring element (14).
