Ball-type synchronizing pivot joint has pair of first outer running grooves and first inner ones, and also second inner running grooves and second outer ones for ball

摘要

The pivot joint has a pair of first outer running grooves (6) and first inner running grooves (18) and also a pair of second inner running grooves (23) and second outer running grooves for the ball. The movement of the balls is limited by securing rings (27, 28), and so is the maximum bend angle between the outer part (1) and the inner part.
