This article discusses the regularities of changes in the activity of abrasive particles in the oil of machine units participating in the process of gear-wheel wear at constant and increasing concentrations. They vary depending on the number of loading cycles of gear teeth, considering the share of crushed abrasive particles in one loading cycle of the gear teeth. This makes it possible to obtain regularities in the change of concentrations of active abrasive particles in the oil depending on the gear modules and the number of loading cycles, taking into the account the fraction of crushed abrasive particles per cycle of loading the gear. This technique can be used to determine the duration of the test of the gear wheel material on samples at a constant total concentration of abrasive particles in the oil change for the units of machines with gear drives operating in the presence of abrasive particles in the working environment. The case under consideration corresponds to the operating conditions of the gear transmission in the unit, which allows calculating the oil change period in the units of machines operating in an abrasive environment.

This article analyzes the status of the issue of rational use of fuel and energy resources of the Republic of Uzbekistan. Currently, the share of renewable energy sources in the fuel and energy balance of the country does not exceed one percent. At the same time, the potential of renewable energy sources of Uzbekistan is about 51 billion tons of oil equivalent, the technical potential of more - 179 00.0 million tons of oil equivalent.

“…Patterns of changes in the concentration of wear products in the oil of the unit. Let's consider the influence of some factors on the accumulation of wear products in the oil of the additional final transmission of the tractor TTZ -100K, consisting of six rolling bearings of three cylindrical straighttoothed gears with an axial distance of the first stage A1 = 0.450 m, the second stage A2 = 0.555 m [2].…”

The article presented by the author considers the greatest wear along the arc of the contact of the bearing ring with the ball is observed on the surface where there is more slippage, i.e. on the face of the groove of the rings. The problem often lies in the low durability of the bearing supports. The authors of this article are invited to analytically evaluate the durability of the bearing with additional consideration of the regularity of changes in the concentration of wear products in the oil of the unit. Uneven load distributions and different elastic constants of materials used for the outer ring and balls, and further with the subsequent improved correction of the resource, which are carried out in accordance with modern requirements. Such a correction involves not only taking into account the impact of lubrication conditions and oil contamination on the bearing life, but also modifying the resource in relation to the fatigue stress limit to the dynamic equivalent load, taking into account many factors of influence.
