BALL SPLINE

摘要

<P>PROBLEM TO BE SOLVED: To provide a ball spline can prevent dints at each ball spline raceway even if an excessive torque is given. Ž<P>SOLUTION: The ball spline is configured so that the ball spline raceways 2b and 21 on a shaft 2 and a ball spline outer cylinder 4 make a four-point contact with a ball 20. A V-spring 22 is arranged at each ball spline raceway 2b of the shaft 2 in such a way as able to pinch the ball 20. An involute spline 23 is installed between adjoining the ball spline raceways 2b.
