Publication number: 20110291506Abstract: Centrifugally decoupling mechanical bearing systems provide thin tensioned metallic ribbons contained in a support structure. This assembly rotates around a stationary shaft being centered at low speeds by the action of the metal ribbons. Tension springs are connected on one end to the ribbons and on the other end to the support structure. The ribbons pass through slots in the inner ring of the support structure. The spring preloading thus insures contact (or near-contact) between the ribbons and the shaft at rotation speeds below the transition speed. Above this speed, however, the centrifugal force on the ribbons produces a tensile force on them that exceeds the spring tensile force so that the ribbons curve outward, effectively decoupling them from mechanical contact with the shaft. They still remain, however, in position to act as a touchdown bearing in case of abnormally high transverse accelerations.Type: ApplicationFiled: May 31, 2011Publication date: December 1, 2011Inventor: Richard F.

Patent number: 7895748Abstract: Disclosed is a method of molding a resin coated bearing. When a molten resin is injected toward a substantially central portion of a disk space of forming dies from a sprue formed on an upper die, the molten resin is filled into a cavity through a film gate after the molten resin is led to the disk space from a pin gate, so that any weld is absent on a resin member, which covers an outer race, thus enabling uniformizing a coating member in resin strength and suppressing generation of crack on the coating member even at the time of high loading. Also, since the film gate formed on a whole peripheral edge of the disk space is formed from a lower die and an upper die, there is an advantage that after working suffices to take out a resin coated bearing from the both dies and to cut a runner in the disk space.Type: GrantFiled: October 13, 2006Date of Patent: March 1, 2011Assignees: Daido Metal Company Ltd., Sunhill Inc.Inventors: Takumi Nomura, Hiroshi Naito, Yoshichika Ito, Hiroshi Ishihara, Shuichi Matsumoto, Terumitsu Tanio

Patent number: 7886441Abstract: A method of manufacturing a rolling bearing device for a road-wheel that includes an outer ring, an inner ring member, rolling elements arranged between the outer ring and the inner ring member, and a shaft body having the inner ring member mounted to an outer periphery includes a caulking step of radially outwardly bending and deforming a cylindrical portion formed at one end side of the shaft body by using a predetermined caulking pressure acting from the one end side toward other end side of the shaft body, thereby forming a caulked portion caulked to an axial end face of the inner ring member. Identification information indicating an existence of the caulked portion so formed is die-stamped on a visually observable surface at the other end side of the shaft body by using the caulking pressure during the caulking step.Type: GrantFiled: November 22, 2005Date of Patent: February 15, 2011Assignee: JTEKT CorporationInventors: Tomomasa Kubo, Tatsuya Yokota

Publication number: 20110026164Abstract: A head slider for supporting a head over a magnetic disk in a hard disk drive, and a method of making the head slider are disclosed. The air bearing surface (ABS) of the head slider includes a relatively deep recess in front of a trailing pad and an island pad. A recess is formed between the trailing pad and the island pad of the ABS. In operation, the recess may reduce the peak pressure of the ABS, resulting in a reduced mid disk (MD) hump without a reduction in other performance parameters. The reduction in peak pressure may also reduce lubrication pick-up from the magnetic disk.Type: ApplicationFiled: July 31, 2009Publication date: February 3, 2011Inventors: Sanford A. Bolasna, Weidong Huang
