Title: Adjusting method for a cross-rolling mill, and mill using this method
Inventor: JOUR JEAN-MARC
IPC: B21B1/20
Filed: 1985-03-26
Granted: 1989-08-03
Abstract: The invention relates to a process for controlling a rolling mill having oblique rolls which is used for rolling metal rods or tubes, and to the rolling mill for carrying out the process. The rolling mill according to the invention comprises at least three rolls distributed round the rolling axis, each of the rolls having a profile generated by revolution of decreasing cross-section, the roll axes not intersecting the rolling axis, and each of the rolls exerting on the product a pressure which permits helicoidal rolling to be carried out. The process involves controlling the forward feed while keeping the angle of inclination of each of the axes of revolution of the rolls constant relative to a secant straight line, the so-called control axis, which is a straight line perpendicular to the rolling axis and intersecting said rolling axis and which traverses the zone of contact between the roll and the product to be rolled. The process also relates to a particular method of rolling in which combined variation of the feed angle and the gap between the rolls is effected during rolling.

Title: Face gear transmission
Inventor: KUIKEN HENDRIK
IPC: F16H1/12
Filed: 1986-12-01
Granted: 1989-05-24
Abstract: Face-gear transmissions in which the teeth-tip-height T can be increased considerably in the region where the face-gear teeth have increased pressure angles a, resulting in considerably increased loading capacity and meshing quotient, all based on meshing cooperation with standard cylindrical gears with either straight (spur) or helical teeth. The angle between the transmission shafts 3, may be 90°, less or over, the shafts may intersect or cross. In case involute toothing is chosen for the cylindrical gear wheel, all well-known advantages remain valid, thus alignment of the transmission is considerably less critical than with bevelled transmissions, axial- pinion loads are less or absent, loading capacity is comparable or better and transmission ratios surpassing approximately 1:5 become the more attractive. In many cases less transmission steps will be possible, reducing size and cost. Simple replacement becomes possible, without any alignment problems. Face gear transmission now may be used for primary, high load, long-life industrial applications.
