Spring clip method for anti-rotation and thrust constraint of a rolling element bearing cartridge

摘要

To solve both axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), a REB cartridge is mounted to the bearing housing in a way that is not rigid, thus allowing for an oil damping film. At the same time, the REB cartridge is held both axially and rotationally, so that the outer race does not rotate relative to the bearing housing. This dual purpose is achieved using a special dual-mode spring clip with at least one anti-rotation feature for engaging the bearing housing and at least one anti-rotation feature for engaging the REB cartridge, thereby axially locating the REB cartridge and preventing rotation of the outer race.
