A Cross Groove Constant Velocity Joint

The present invention relates to a cross groove constant velocity joint, and more particularly may be to prevent the locking operation between the jeolgak operation when the outer ring and the inner ring prevent damage to the cage, and to implement a reliable power transmission, further flat equivalents of plunging force which may be the distribution relates to a cross groove constant velocity joint. The present invention for achieving this purpose is that the outer race with a plurality of lateral grooves on the inner surface formed; An inner ring accommodated in the inside of the outer ring is formed with a plurality of the inner grooves and the outer surface; It is accommodated in the outer groove and the inner groove plurality of balls that is responsible for the force transmission between the outer ring and the inner ring and; Disposed between the outer ring and the inner ring, and comprising a cage provided with a window that defines the moving area of ​​the ball, the outer groove and its inner side a groove which matdaeeung is opposed to be mutually cross, wherein the outer grooves and the inner grooves are each outer ring and with respect to the side of the inner ring to each other comprises two sets of lateral grooves and the inner grooves having a different lateral angle of inclination, the outer grooves and the inner grooves of one kind is tilted in a predetermined direction with respect to the axial direction, which are mutually symmetrical with respect to the center axis It provides a cross groove constant velocity joint, characterized in that the bottom is formed to have the inclination angle.
