NTRODUCTION

The development of the country's agro-industrial
complex depends on the level of technical support
for agriculture, the development and introduction
of high-efficiency machines, and the use of
technology. At each of these stages, a reliable

comprehensive assessment is necessary to
manage the processes of development, research,
production, and operation of machines. That is,
the Republic of Uzbekistan is a cotton-growing
country, where agricultural machinery has to

work in difficult soil-climatic conditions,
characterized by high temperature and dustiness
of the air, which is associated with intensive wear
of the machine [1-4].

Currently, in the agricultural sector of our
Republic, more than 30 thousand TTZ and MTZ
models (TTZ-60, TTZ-80 and MTZ-80, MTZ-82)
are used for planting, applying mineral fertilizers,
inter-row processing and harvesting. being used
in harvesting operations [5-11].

In the Republic of Uzbekistan, the operation of
these tractors is carried out in difficult working
conditions. The climate of our republic is sharply
continental. In the republic, in the summer
season, the air temperature raises sharply, the
amount of precipitation decreases, and intensive
evaporation is observed. The highest extreme
temperatures are observed in June and July
(Table 1) [12-19].

Table 1 shows that the highest daily air
temperature is observed in the Surkhandarya
region. An increase in air temperature leads to
deterioration of the physicochemical properties
of transmission oil, in particular, a decrease in
kinematic viscosity and an acceleration of
corrosion of the friction parts by mixing with dust

particles that enter the gearbox from the outside
and are formed internally due to mechanical
impurities [20-27]. The pressure inside the
gearbox increases, which causes the gaskets to
fail. The values of the average relative humidity of
the air in the regions of the Republic of
Uzbekistan are presented in Table 2 [28-35].

In the republic, the indicators of relative air
humidity vary from 30 to 90 per cent throughout
the year. The lowest relative humidity is observed
in May-September [36-42]. That's why it's
universally popular in these months tractors
work in dry and dusty weather. In the agricultural
conditions of our republic, the increase in loading
of universal wheeled tractors also corresponds to
the months of May-September (Table 3).

The operation of universal tractors in conditions
with high dust content in the air, as mentioned
above, leads to severe contamination of the
transmission oil with abrasive particles through
the tightness of the box. According to
NVMikhailovsky, the amount of dust at the level
of air permeability during cotton cultivation and
harvesting has the following values. [43-49]:

As can be seen from Table 3, the increase in
airborne dust is dominated by planting, cotton
and harvesting.

The composition of atmospheric dust in the form
of clouds formed only under the influence of wind
(at a wind speed of 5.2-6.7 m/s, at a temperature
of 32-

34 ℃) is presented in Table 4 [3].

Dust content, g/m3

1.5-1.60.9-1.00.6-0.70.3-0.4

The study of the mineralogical and dispersion
composition of grey soil dust clouds showed that
they contain 65-70% silicon oxide, as well as
about 10% aluminium oxide and 5% iron oxide.
About 95% of these particles are up to 50 µm and
about 5% are up to 100 µm. The average
dispersed content of dust is in the range of 20-40
microns [45-52].

It can be seen that the most abrasive particle in
the dust is silicon oxide. The hardness of these
particles exceeds the hardness of the abrasive
particles resulting from the friction of the friction
parts of the gearbox, which is the main reason for
the rapid failure of the parts.

C

ONCLUSION

In conclusion, it can be said that the rise of dust,
high air temperature, and dry climatic conditions
during the operation of universal crawler tractors
lead to contamination of the gearbox oil. As a
result, there is an increase in the rate of
consumption and a state of rapid failure. The
main problem is the lack of oil filters in the
gearbox lubrication system of universal tractors.
This indicates the need for scientific research to
solve the problems in this system.
