Abstract

PURPOSE:To apply up-and-down load to a Gothic arch bearing by bringing a truck rail into contact with a rectilinear plane of an orbit mounted on a slide unit and a ball only at a contact point symmetrical about the center line of the ball with a fixed angle. CONSTITUTION:When downward load D is applied to the upper point 10 of contact of a slide unit 2 so that load f1 acts upon a ball 3, load F1 controlling loading capacity of a bearing is determined by an angle B of a normal direction. Load F2 influenced by an angle C of an normal direction acts in the same manner upon upward load f2 at the lower point 11 of contact. If the angle B is below 45 deg., and the angle C is above 45 deg., F1 can be smaller than F2, even if f1 is larger than f2. Accordingly, the downward load capacity of the bearing can be larger than the upward load capacity, and the bearing is reduced to compact size so as to receive every radial load and moment load.
