The ways to ensure a rational load distribution on the bearings by creating an axle box

Abstract

Long-term experience of operation on the railways of Ukraine cylindrical roller bearings shows that they have insufficient reliability. The actual durability of the railway axle bearings is much lower than the calculated one. The reason for this is an uneven load distribution between the rolling elements and along the forming rollers [1, 2]. The peculiarity of the construction of the axle box of the freight car and the connection zone with the side frame of the bogie consists in the fact that during operation it is inevitable to wear both the body of the axle box and the axle frame of the side frame of the bogie. At the same time, significant gaps appear in the joints of the case of the axle box and the side frame.
