DAMAGE TO ROLLER-BEARING AXLE-BOXES CAUSED BY LOOSE INSIDE RINGS

SCHADEN AN ROLLENACHSLAGERN DURCH LOSE INNENRINGE

An account of research into the progressive loosening in service of the inside rings of cylindrical roller bearing axle-boxes. The diagrams provided show the variations in dimension of the inside borings of the rings after a prolonged stay in temperatures of the order of those experienced in service, and under the effect of running under load. Different causes of this phenomenon are considered: 1) superficial corrosion under pressure; 2) austenitic poverty of the floating surface. They are not clearly shown. In the case of heat treatment, it is necessary for a compromise to be reached between hardening of the steel and the most satisfactory stabilization of the dimensions. Experiments have been carried out in order to detect loose rings by ultrasonic means, but they have not provided a useful guide. In conclusion, the authors set out a number of recommendations.
