Patent ID: 8678665

Claim:
A bearing arrangement of a transmission to reduce the effects of thermal expansion comprising: a housing of the transmission made from a first material having a first thermal expansion coefficient; a first thrust bearing having an inner race and being retained on substantially one end of a shaft, substantially the other end of said shaft being supported by a roller bearing, wherein the shaft is made from a second material having a second thermal expansion coefficient; an object rotating on and with respect to the shaft; a second thrust bearing having an inner race and being retained on said object with a bearing retainer that is arranged between the first and second thrust bearings; and a thrust washer that engages the bearing retainer, wherein the bearing retainer and thrust washer are sandwiched between the first and second thrust bearings so that the inner race of the one of the first and second thrust bearings engages the bearing retainer and the inner race of the other one of the first and second thrust bearings engages the thrust washer.
