20.500.12556/RUL-105268 Analysis on damage to rolling bearings at small turning angles A test rig was developed for testing air springs. It uses the energy returned by the spring during unloading. The springs are loaded by means of a lever oscillating around its rotation point at a small angle. During operation, it was determined that rotation point bearings are critical elements of the test rig. This paper shows and analyses the damage that occurs on bearing ring raceways. Contact pressure and stress under individual rolling elements were calculated by using the finite element method (FEM). Mechanisms of the formation and propagation of damage were identified. Optical and electronic microscopy was used for confirming the mechanisms of damage formation. The microstructure of damaged material was analysed. It was found that depressions on bearing ring raceways form due to material fatigue and fretting. The required bearing replacement frequency was determined with respect to load. damage of rolling bearing wear partially-rotatory machines false brinelling fatigue fretting poškodba kotalnega ležaja majhen kot zasuka ležaja obraba torna korozija nepravi vtiski true false true Angleški jezik Slovenski jezik Podatek o licenci CC BY 4.0 je naveden na pristajalni strani članka – glej izvorni URL zgoraj.
