METHOD FOR INSPECTION OF BALLS Russian patent published in 1994 - IPC

FIELD: mechanical engineering; in-process and final inspection of ball bearings. SUBSTANCE: ball is installed on internal surface of cone in contact therewith along ball circumference. Rotation axis of ball is arranged vertically and ball is rotated around the second axis by means of the contact of the ball circumference with the internal surface of the second cone whose rotation axis is set at an angle of 90^°± α/2<β<175^° to vertical where β taper angle of cone on which the ball is mounted. EFFECT: higher accuracy and efficiency of inspection. 1 dwg
