Abstract
A prediction method of the agitation torque and the quantity of oil in tapered roller bearings is developed using CFD analysis. The method was verified by experiments. Using this technique, we succeeded in controlling the oil flow in bearings and developed a low torque tapered roller bearing. The torque in this bearing is reduced due to low agitation resistance, while the quantity of oil around the sliding contact surfaces (i.e. the flange of the inner ring) is sufficient.
