Patent application numberDescriptionPublished
20090054165Constant Velocity Universal Joint and Inner Member of the Same - Automatic installation of a circlip is facilitated even when an axial length (inner race width) of a protrusion of an inner race is reduced. An inner race (02-26-2009
20090136287Slide-Type Constant Velocity Universal Joint - The present invention provides a light and compact slide-type constant velocity universal joint that can have a maximum operating angle of 30° or more through optimization of a ball contact angle relative to ball grooves, a ball contact ratio, and a cage offset amount. The present invention is the slide-type constant velocity universal joint including an outer ring 05-28-2009
20100069164FIXED TYPE CONSTANT VELOCITY UNIVERSAL JOINT - Provided is a fixed type constant velocity universal joint capable of securing smooth rotation and reducing a load on a cage even at a large operating angle and at a time of bearing large torque. The fixed type constant velocity universal joint includes an outer joint member having opened one end and an inner spherical surface in which multiple track grooves are circumferentially formed in an axial direction; an inner joint member (03-18-2010
20100113168CONSTANT VELOCITY UNIVERSAL JOINT - Provided is a constant velocity universal joint capable of being smoothly rotated even when a high operating angle is formed and large torque is born and of reducing excessive load applied to the cage so as to strengthen the cage. The constant velocity universal joint includes an outer joint member having an inner spherical surface (05-06-2010
20100210368CONSTANT VELOCITY UNIVERSAL JOINT - In order to ensure sufficient strength of an inner joint member even when the thickness of the inner joint member is reduced for achieving reduction in weight and size and even when a high operating angle is formed and high load torque is applied, a constant velocity universal joint includes: an outer joint member (08-19-2010
20100234115Constant velocity universal joint - The present invention provides a compact constant velocity universal joint having high strength, and superior operability and durability. In the constant velocity universal joint of the present invention, an offset angle ø09-16-2010
20100234116FIXED CONSTANT VELOCITY UNIVERSAL JOINT - Provided is a fixed type constant velocity universal joint capable of obtaining, in every angular region, wear resistance against rolling of balls and a stable high fatigue strength characteristic. The fixed type constant velocity universal joint includes: an outer joint member including an inner surface (09-16-2010
20110059804FIXED-TYPE, CONSTANT-VELOCITY UNIVERSAL JOINT - Provided is a fixed type constant velocity universal joint which is capable of achieving the following even at the time of an unexpected high-angle operation, in particular, even when an angle expected during use of a constant velocity universal joint is exceeded: reduction of stress generated when balls and edge portions interfere with each other, suppression of chipping of the edge portions, and prolongation of a service life of the joint as a whole. The fixed type constant velocity universal joint includes: an outer joint member having an inner surface (03-10-2011
