ABSTRACT:
A device for automatically adjusting the clearances in a roller bearing due to thermal expansion, constituting a tapered roller bearing having a dual track oppositely tapered inner race and a pair of single track tapered outer races, each outer race being in communication with a pair of coaxial, hydraulically loaded annular pistons, each of which translates in annular piston cylinders, supplied with hydraulic fluid. The hydraulic pressure of the fluid is maintained through an accumulator at a preselectable constant pressure to permit the outer races to translate axially, against the annular piston, as the inner race expands radially due to thermal expansion. Upon thermal contraction, the pressure forces the annular pistons axially toward the outer races, which, due to the taper of the races and the bearing elements, reduces the clearance created due to the thermal contraction.
