A
constant velocity joint for a drive
system comprises: an outer joint member having a plurality of inwardly facing outer ball grooves, the outer ball grooves consisting of a first group of grooves, each groove of which having a skewed groove shape with a first
skew angle other than zero and alternately arranged in opposite directions relative to an axis of rotation of outer joint member, and a second group of grooves, each groove of which having a skewed groove shape with a second
skew angle other than zero and alternately arranged in opposite directions relative to an axis of rotation of outer joint member, the second
skew angle less than the first
skew angle; and an inner joint member disposed inside the outer joint member and having a plurality of outwardly facing inner ball grooves consisting of a first group of grooves, each groove of which having a skewed groove shape with a first
skew angle other than zero and alternately arranged in opposite directions relative to an axis of rotation of inner joint member, and a second group of grooves, each groove of which having a skewed groove shape with a second
skew angle other than zero and alternately arranged in opposite directions relative to an axis of rotation of inner joint member, the second skew angle less than the first skew angle, each inner ball groove of the inner joint member being coupled with a corresponding outer ball groove of the outer joint member generally in crossed pair. In addition to the differentiated skew angles, the contact angles of the balls in the first and second group of grooves and other configurations may also be differentiated.
