Patent DE-2735694-A1 (DE)
Title: Roller bearing with controllable axial thrust - where some rollers tilt in the bearing cage when bearing temp. increases
Inventor: HACKEWITZ FRIEDRICH-WILHELM VO
IPC: F16C19/26
Filed: 1977-08-08
Abstract: The bearing has an inner race and an outer race sepd. by a bearing cage contg. two different types (a,b) of rollers. Rollers (a) are made of steel and rotates on an axis (a) which remains parallel with the axis of the roller bearing (arb); but rollers (b) are made of softer material, e.g. plastic, and have a slightly smaller dia. than rollers (a). Rigid cage webs (wa) hold rollers (a), whereas rollers (b) are located between pairs of webs (wb) which function like a bimetal so that thermal expansion or centrifugal force causes rollers (b) to tilt so their axes (b) do not remain parallel with axis (arb); the axial thrust increases with the angle of tilt. Automatic control of the axial thrust is achieved using a simple, inexpensive bearing.
