The influence of low temperatures on internal losses in transmission units
The paper presents distribution data to equipment failures during the year, typical for conditions of OAO «Surgutneftegaz» and justified demands on drive train lubricants to reduce internal losses. In the operation of automotive vehicles in the off-season there is an increase in the number of failures. Moreover, the number of failures of transmission components significantly exceeds the number of failures of internal combustion engines. This is especially true for the autumn-winter period. The causes of failures related to the processes of irrigation and transmission oils change their viscosity-temperature properties, which increases internal losses in the transmission units. The use of properly selected transmission oils helps to reduce internal losses and reduce energy consumption in winter of the equipment.
