Lubrication life of cylindrical roller bearings for traction motors of railway vehicles (Effects of bearing temperature, vibration acceleration, and grease mass)

Nihon Kikai Gakkai ronbunshu
In general, the life of a rolling bearing is calculated as the total number of rotations until rolling fatigue occurs on the raceway. However, when rolling bearings are used under light loads and high rotational speeds, they are damaged not by rolling ...
