Abstract
A peritrochoid curved surface generating apparatus comprises an outer cylinder rotatably supported on a frame, a first central shaft rotatably journalled in the rotating axis of the outer cylinder, an inner cylinder adjustably fixed within an eccentric opening of the outer cylinder, an inner cylinder central shaft rotatably journalled in an axis of the inner cylinder, a second central shaft rotatably journalled in an eccentric opening of the inner cylinder and supporting a work table, a gear train for transmitting the rotation of the first central shaft to the second central shaft through the inner cylinder central shaft, a cylindrical tool rotatable about its axis and a rocking device supporting the tool and rockable in synchronism with the rotation of the outer cylinder. A distance between the first and second shafts is adjustable and a rocking angle of the rocking device is also adjustable, so that the apparatus can be used for generating various peritrochoid curved surfaces different in configuration without any interference between a tool and a workpiece.
