Abstract
A constant velocity ratio universal joint of the tripode type including a first joint member having a first rotational axis and three tracks circumferentially spaced about the axis and extending lengthwise thereof. A second joint member is also included having a second rotational axis and three arms extending into the respective tracks of the first joint member. Each of the arms has a respective arm axis, and a roller is carried by each arm. Each roller has a roller axis and an external circumferential surface which engages opposite sides of the respective track in the first joint member. The external circumferential surface of each roller is a surface of revolution about the roller axis of a convex generally arcuate line having a meridian radius. The roller is characterized in that the meridian radius is greater than the equatorial radius.
