20090253522 | Boot for Universal Joint - To prevent inverting of a mountain portion ( | 10-08-2009 |
20090291866 | GREASE COMPOSITIONS FOR CONSTANT VELOCITY JOINTS AND CONSTANT VELOCITY JOINTS - The invention provides a grease composition for constant velocity joints and constant velocity joints in which the grease composition is packed. The composition comprises (a) a base oil comprising a synthetic oil; (b) a thickening agent; (c) a molybdenum sulfurized dialkyl dithiocarbamate; (d) a thiophosphate; and (e) a zinc sulfurized dialkyl dithiocarbamate. The composition can reduce low temperature rotational torque and folding torque in constant velocity joints while inhibiting deterioration of a boot material comprising a silicone rubber. | 11-26-2009 |

20110212788 | FIXED CONSTANT VELOCITY UNIVERSAL JOINT, METHOD OF MANUFACTURING FIXED CONSTANT VELOCITY UNIVERSAL JOINT, AND BEARING DEVICE ADAPTED FOR USE IN DRIVING WHEEL AND USING FIXED CONSTANT VELOCITY UNIVERSAL JOINT - Provided is a fixed type constant velocity universal joint, including: an outer joint member having an inner spherical surface provided with a plurality of track grooves extending in an axial direction; an inner joint member having an outer spherical surface provided with a plurality of track grooves extending in the axial direction in pairs with the plurality of track grooves of the outer joint member; a plurality of balls interposed between the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member so as to transmit torque; and a cage interposed between the inner spherical surface of the outer joint member and the outer spherical surface of the inner joint member so as to hold the plurality of balls, at least one of the plurality of track grooves of the outer joint member and the plurality of track grooves of the inner joint member being formed by cold-forging finishing, in which components including the outer joint member, the inner joint member, the plurality of balls, and the cage are assembled to each other based on matching in which the plurality of balls and the cage each having a rank corresponding to a measured value of a PCD of the outer joint member, which has been arbitrarily selected, and to a measured value of a PCD of the inner joint member, which has been arbitrarily selected, are selected with respect to the arbitrarily selected outer joint member and the arbitrarily selected inner joint member. | 09-01-2011 |
20110269556 | OUTER JOINT MEMBER FOR FIXED CONSTANT VELOCITY UNIVERSAL JOINT - Provided is an outer joint member for a fixed type constant velocity universal joint, the outer joint member contributing to reduction of the number of man-hours through reduction of the number of post processes after a forging process, and to an increase in yield, and reduction of manufacturing cost. The outer joint member for a fixed type constant velocity universal joint includes a cup section ( | 11-03-2011 |
20140035350 | BEARING DEVICE FOR DRIVING WHEEL - A driving-wheel bearing device includes an outer race having double-row outer raceway surfaces formed on an inner periphery thereof, a hub wheel and an inner race having a wheel attachment flange at one end thereof and double-row inner raceway surfaces on an outer periphery thereof, and double-row rolling elements interposed between the outer raceway surfaces of the outer race and the inner raceway surfaces of the hub wheel and the inner race, the hub wheel having a shaft hole into which a stem section extending from an outer joint member of a constant velocity universal joint is spline-fitted by being press-fitted, in which a plate having a molybdenum coating layer or a fluorine-resin coating layer formed thereon and having a plate thickness ranging from 0.5 mm to 2 mm is interposed between opposite surfaces of a shoulder portion of the outer joint member and an crimped portion of the hub wheel. | 02-06-2014 |
