Abstract
PURPOSE: To secure stabilized bearing performance for a long period of time, by making an opening between the internal circumference of a cylindrical bearing support and the external circumference of a bearing and making a through hole inside the bearing support and bearing pressure unit.
CONSTITUTION: A through hole 15b is made on the internal circumference of the pressure unit 15a, and an oil return 15c, for returning oil between the internal circumference and the bearing support 6 when the support is assembled in the pressure unit, is also made in the pressure unit. Sealing pegs 16, 17 are used for filling in an oilless wick 12 so that the wick is protruded from an end of a feed oil passage 15b nor enters in the oil return 15c. Thus the oil exposed due to thermal expansion is returned to the wick 12 through the oil return 15c.
