The influence of climatic factors on the destruction of shock-loaded bearings of mobile machines

The paper for the first time considers the causes of destruction of shock-loaded sealed rolling bearings lubricated with greases. A previously unimplemented version of the study of greases on the surfaces of bearing parts (bearing races of the inner and outer parts of the bearing, roller, and the separator) on a scanning electron microscope JEOLJMC-5700 is presented, besides, the X-ray phase analysis is performed. The work carried out allowed to draw conclusions about the influence of the climatic component, which affects the duration of the bearings. The reasons for the increase in the flow of failures due to the destruction of rolling bearings during the operation of equipment at low temperatures are substantiated.
