ASSEMBLING METHOD OF INNER AND BALL CAGE ASSEMBLY TO OUTER AND DEVICE THEREOF FOR CONSTANT VELOCITY BALL JOINT

摘要

PURPOSE:To surely assemble an assembling body of an inner and a ball cage into an outer by utilizing linear projections in an outer as guides for balls, and smoothly engaging balls with track grooves adjacent to the linear projections. CONSTITUTION:In an outer A, linear projections A2 on both sides in a prescribed diametral direction among the linear projections A2 between track grooves of it are held in inclined phase by 30 deg. against the outer transport direction. An assembling body W constituted out of an inner and a ball cage is inserted into the outer A in the condition in which respective ball windows C1 are oppositely faced to the linear projections A2 and held with a holding member 23. Consequently, balls D held with the ball windows C1 are guided with the sides of the linear projections A2. After inserting, a projection 24d engaging with an obliquely upward ball window adjacent to the ball window C1 receiving the ball D is formed on an engaging member 24b capable of advancing and retreating provided on the holding member 23, and by the advancing and retreating the assembling body is rotated. Next, the assembling body W is inclined downward and the outer A and the assembling body W are assembled together.
