Abstract

This paper investigates the factors affecting the strength of abrasive particles in tractor gearbox oil operating in dusty conditions. The study focuses on gearboxes with constant mesh gears, categorized into two types based on torque transmission. The research aims to determine the degree of activity of abrasive particles influencing gear teeth wear resistance. A methodology for calculating the possibility of crushing abrasive particles based on their concentration, size, and strength is proposed. The influence of normal force arising from friction torque, rolling bearings, and oil agitation on abrasive particles is also examined. The findings indicate that when gear transmission does not transmit torque, the normal force does not lead to abrasive particle crushing, resulting in high wear capacity in the gearbox oil. However, under the influence of normal force from the torque transmitted by the internal combustion engine, abrasive particles in the tooth contact zone are crushed, reducing their wear capacity. The study’s results contribute to understanding the factors affecting abrasive particle strength in tractor gearboxes operating in dusty conditions, providing insights into improving system design and operation for enhanced durability and efficiency.
