Improving the reliability and durability of the gear wheels of the main transmission of fi re trucks by improving the tribotechnical characteristics of transmission oils

Abstract

The issues of increasing the reliability and durability for fi re trucks the use of highly соeffi cient lubricants in friction units of machines, improving the antiwear properties of hypoid oils used to lubricate the gear wheels of the main drive in transmissions of the trucks are considered. An antiwear additive based on soft metal stearates is proposed. The results tribotechnical tests of the developed antiwear additive, which indicate the effectiveness of its application, are presented.
