Early subsurface cracks make significant changes to the dynamic responses of full ceramic
ball bearings, and complex space environment brings challenges to the status monitoring of …

The rolling bearing misalignment may lead to fracture failure of the cage. However, the
research on the vibration response of the rotor system caused by bearing misalignment and …

Cage stability is an essential indicator of the guaranteed efficiency and reliability of the
rolling element bearing. Moreover, cage instability can greatly shorten the bearing's service …

From a kinematic point of view, rolling elements should continuously roll on the raceways of
rolling element bearings. When the dynamic behaviour is also considered, pure rolling …

As the core for the lubrication and operation of space ball bearing, the porous non-metallic
cage with oil-impregnated will cause catastrophic results in case of fault. The principal used …

The crack initiation and propagation on the cage bridge surface can change the cage
structural stiffness and clearances, which may lead to the cage failure ahead of time and …

Tribology at cryogenic temperatures has attracted much attention since the 1950s with the
acceleration of its applications in high-tech equipment such as cryogenic wind tunnels …

A comprehensive dynamic model of ball bearing focusing on structure flexible deformations
is developed in this paper. The cage is split into several discrete segments linked by …

Full ceramic ball bearings are widely used in space technology and other cryocooling
conditions due to a series of advantages. In order to verify the cryogenic adaptability of full …
