Abstract
A constant velocity joint comprises an outer joint member 1 having eight curved guide grooves 1b axially formed in the spherical inner surface 1a thereof, an inner joint member 2 having eight curved guide grooves 2b axially formed in the spherical outer surface 2a thereof and serrations (or splines) 2c formed on the inner surface for connection to a shaft portion 5, eight torque transmitting balls 3 disposed in ball tracks defined between the guide grooves 1b and 2b of the outer and inner joint members 1 and 2, and a cage 4 for retaining the torque transmitting balls 3.
Claims32
A constant velocity joint comprising:
- an outer joint member having a plurality of axially extending curved guide grooves formed in the spherical inner surface thereof;
- an inner joint member having a plurality of axially extending curved guide grooves formed in the spherical outer surface thereof;
- a plurality of ball tracks defined between said guide grooves of said outer joint member and said guide grooves of said inner joint member corresponding thereto, all of said ball tracks being enlarged in wedge form in one sense of the axial direction;
- a torque transmitting ball disposed in each of said plurality of ball tracks;
- a cage having a plurality of pockets for storing said torque transmitting balls, wherein the number of said ball tracks and the number of said torque transmitting balls disposed are eight respectively.
A constant velocity joint comprising:
- an outer joint member having a plurality of axially extending guide grooves formed in the spherical inner surface thereof, said guide grooves of said outer joint member each having a curved portion and a straight portion;
- an inner joint member having a plurality of axially extending guide grooves formed in the spherical outer surface thereof, said guide grooves of said inner joint member each having a curved portion and a straight portion;
- a plurality of ball tracks defined between said guide grooves of said outer joint member and said guide grooves of said inner joint member corresponding thereto, all of said ball tracks being enlarged in wedge form in one sense of the axial direction;
- a torque transmitting ball disposed in each of said plurality of ball tracks;
- a cage having a plurality of pockets for storing said torque transmitting balls, wherein the number of said ball tracks and the number of said torque transmitting balls are eight respectively.
