SPRING CLIP METHOD FOR ANTI-ROTATION AND THRUST CONSTRAINT OF A ROLLING ELEMENT BEARING CARTRIDGE

摘要

To solve axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), REB cartridges are installed in bearing housings in a non-rigid manner, thereby allowing oil decaying membranes. At the same time, the REB cartridge is held in the axial and rotational directions such that the outer ring is not rotated relative to the bearing housing. This dual purpose uses a special dual mode spring clip having at least one anti-rotation profile for engaging the bearing housing and at least one anti-rotation profile for engaging the REB cartridge, thereby positioning the REB cartridge in the axial direction Thereby preventing rotation of the outer ring.
