20110268381 | ROLLING BEARING DEVICE - A rolling bearing | 11-03-2011 |
20110280510 | ROLLING BEARING - A rolling bearing includes: an inner ring; an outer ring; a plurality of rolling elements; a retainer; and a sealing member. First to third lubricant reservoir portions that store the lubricant are respectively formed on the radially inner side of the retainer, on the inner side of the sealing member, and in an inner peripheral surface of the outer ring at a position near a raceway. An inclined first guide surface that guides the lubricant from the second lubricant reservoir portion toward the raceway is formed in an inner surface of the sealing member. An inclined second guide surface contiguous with the first guide surface and guiding the lubricant toward the raceway is formed in the inner peripheral surface of the outer ring. The first lubricant reservoir portion of the retainer is in communication with pockets of the retainer, which accommodate the rolling elements. | 11-17-2011 |
20120073533 | CAMSHAFT DEVICE, ENGINE WITH SAME, AND METHOD FOR MANUFACTURING CAMSHAFT DEVICE - A camshaft device ( | 03-29-2012 |
20120141060 | OUTER RING OF TAPERED ROLLER BEARING AND TAPERED ROLLER BEARING - An outer ring has a tapered tubular portion having a tapered raceway surface, a small diameter side extension portion that extends radially outward from a small diameter side edge of the tapered tubular portion, and a large diameter side extension portion that extends from a large diameter side edge of the tapered tubular portion in a direction away from the axis of the outer ring. The small diameter side extension portion and the large diameter side extension portion are larger in thickness than the tapered tubular portion. | 06-07-2012 |
20120174882 | CAMSHAFT APPARATUS - Among a plurality of bearings that rotatably support a camshaft ( | 07-12-2012 |
20120321234 | CONICAL BEARING - In a cage, parallel portions are formed that face a raceway surface of a inner ring in a radial direction and that extend in an axial direction from a small diameter side of a tapered raceway surface toward a side of a large flange part. Grooves extending in the axial direction are formed on inner surfaces of the parallel portions. Between the tapered raceway surface of the inner ring and the inner surfaces of the parallel portions, gaps are formed that allow gear oil to be retained in the grooves through agency of surface tension of the gear oil when the cage is stationary relative to the inner ring. | 12-20-2012 |
20120321237 | CONICAL ROLLER CAGE - A conical roller cage that implements a conical roller bearing that is able to suppress torque and that is able to smoothly supply lubricant to a raceway surface includes: a small-diameter annular portion, a large-diameter annular portion having a bore diameter larger than a bore diameter of the small-diameter annular portion, pillar portions that couple the small-diameter annular portion to the large-diameter annular portion and that are located at intervals from each other in a circumferential direction, roller partition wall portions each radially extending from a radial end face of a corresponding one of the pillar portions, and canopy portions each protruding from a radial end portion of a corresponding one the roller partition wall portions, at an opposite side to a side of the pillar portion, toward both sides in the circumferential direction. | 12-20-2012 |
20130239727 | CAMSHAFT DEVICE - An intake camshaft device | 09-19-2013 |
20140145372 | METHOD OF MOLDING BOOT FOR CONSTANT VELOCITY JOINT - A method of molding a boot for a constant velocity joint includes: molding a compact by injection molding; raising split dies of an inner die so as to separate the split dies from a set ring; raising a core shaft of the inner die so as to separate the core shaft from the split dies; separating each of the split dies from the compact; introducing a lower end portion of the separated split die into the set ring along an engaging surface; and inserting a lower end portion of the core shaft through the set ring from above the set ring, and pressing upper end portions of the split dies downward by a protruding portion at an upper end portion of the core shaft so that the lower end portions of the split dies are engaged with the engaging surface and the split dies are brought into close contact. | 05-29-2014 |
20140147547 | MOLDING DIE FOR MOLDING BOOT FOR CONSTANT VELOCITY JOINT - An inner die of a molding die includes a core shaft, split dies radially arranged along an outer peripheral surface of the core shaft around an axis of the core shaft, which serves as a center, and a cylindrical set ring arranged below the split dies, the core shaft being inserted through the set ring. An annular engaging surface, which is a tapered surface whose diameter is gradually reduced downward, is formed in an inner peripheral side of an upper end portion of the set ring, and lower end portions of the respective split dies are introduced into, and engaged with the engaging surface. The molding die includes a pressing portion that presses downward upper end portions of the respective split dies introduced into the set ring, so as to move the lower end portions of the respective split dies toward the axis along the engaging surface. | 05-29-2014 |
20140248015 | ROLLING BEARING DEVICE - A lubricant supply unit that supplies lubricating oil to a raceway groove of an inner ring is fixed to an outer ring. The lubricant supply unit is provided with a first and second radially separated electrodes used to supply electric power from an external power source to the micropump. Each of the first and second radially separated electrodes is fixed to an outer face of a tank that is stationary relative to the micropump so as to be exposed on the outside of the lubricant supply unit. The first radially separated electrode is arranged so as to be apart from the second radially separated electrode. | 09-04-2014 |
