Latest Patents

Yokota's latest patents include a method of manufacturing a wheel bearing apparatus and a wheel rolling bearing device. The method of manufacturing involves creating a wheel bearing apparatus that consists of an outer ring, a rolling element, a hub spindle, and an inner ring member. The hub spindle is positioned inward of the outer ring in a radial direction via the rolling element. The inner ring member is fitted onto the hub spindle and secured by a clinched portion, which is formed by clinching the spindle end portion of the hub spindle outward in the radial direction. The process includes plating a predetermined area, removing the plating from the spindle end portion, and clinching the spindle end portion to create the clinched portion. The wheel rolling bearing device features an inner ring member with multiple flange portions formed by cold forging. A tapered surface is created on the inner ring member, gradually increasing in diameter from the inner side to the outer side. A seal member is attached to the outer periphery of the outer end portion of the outer ring member, with a seal lip in sliding contact with the tapered surface.
