20130252747 | CROSS GROOVE TYPE CONSTANT VELOCITY JOINT - A constant velocity joint for a drive system includes: an outer joint member and an inner joint member, each having a plurality of ball grooves, the ball grooves consisting of a first group of grooves of 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 the outer and inner joint members, and a second group of grooves of 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 the outer and inner joint members, the second skew angle less than the first skew angle. In addition to the differentiated skew angles, the contact angles of the balls in the first and second group of grooves may also be differentiated. | 09-26-2013 |
20130288810 | Universal Joint for a Downhole Drilling Motor - A universal joint carried by an elongate body having an axis. The universal joint has an inner race that pivots omni-directionally within an outer race and a series of first and second opposed cavities formed in the inner race and the outer race. There are a plurality of torque transfer elements, each torque transfer element having a first portion that engages a first cavity and a second portion that engages a corresponding second cavity. The first cavity is a socket that permits rotation of the first portion within the first cavity as the inner race pivots omni-directionally within the outer race and the second cavity is a track oriented in the direction of the axis of the elongate body. The second portion moves along the track as the inner race pivots omni-directionally within the outer race of the second portion along the track. The second portion has at least one drive surface that engages an inner surface of the track at more than one point along the direction of the track. | 10-31-2013 |
20140038732 | CONSTANT VELOCITY UNIVERSAL JOINT - A constant-velocity universal joint includes an outer joint member; an inner joint member arranged in an inside of the outer joint member; and torque transmitting members.
