摘要： A manufacturing method is used for an outer joint member of a constant velocity universal joint. The outer joint member includes a cup section having track grooves formed in its inner periphery, which are engageable with torque transmitting elements, and a shaft section formed at a bottom portion of the cup section. The manufacturing method includes welding the cup and shaft members by irradiating a beam to joining end portions of the cup and shaft members, causing an outer surface including the welded portion to be formed into a flat smooth surface by removal processing, irradiating ultrasonic waves to the flat smooth surface with one probe at an incident angle which prevents total reflection in a circumferential angle beam flaw detection method, and setting a focal point of the ultrasonic waves to positions from a surface to an inside of the welded portion, to thereby perform inspection.

摘要： In a fixed type constant velocity universal joint, track grooves of an outer joint member include first track groove portions positioned on an interior side and second track groove portions positioned on an opening side. The first track groove portions each have an arc-shaped ball raceway center line having a curvature center that is prevented from being offset in an axial direction of the outer joint member with respect to a joint center. Planes each including at least the ball raceway center line and the joint center are inclined with respect to a joint axial line with their inclination directions alternately opposite to each other in the first track groove portions that are adjacent to each other in a peripheral direction of the outer joint member.

摘要： Track grooves of an outer joint member include first and second track groove portions positioned on interior and opening sides, respectively. Each first track groove portion has an arc shape with a curvature center at a position offset to the opening side with respect to a joint center. The first track groove portions are inclined in a peripheral direction of the outer joint member with respect to a joint axial line and adjacent to each other in the peripheral direction with their inclination directions opposite to each other. Each second track groove portion has a shape that is different than each of the first track groove portions so as to increase an effective track length at a maximum operating angle. The second track groove portions are connected to the first track groove portions at a position on the opening side with respect to the joint center.

摘要： A constant velocity twin ball joint, having an outer joint part with outer ball tracks, an inner joint part with inner ball tracks. Circumferentially adjoining pairs of tracks comprise center lines of the outer and inner ball tracks which, when the longitudinal axes are aligned, are positioned in planes which extend parallel relative to one another and are symmetric relative to the longitudinal axes. A ball cage is positioned between the outer joint part and the inner joint part and comprises circumferentially distributed cage windows which each accommodate pairs of balls of adjoining pairs of tracks positioned in parallel planes. The circumferential length of second cage windows for second pairs of balls is smaller than the circumferential length of first cage windows for first pairs of balls.
