摘要： A tool for producing crown wheels by means of a generating process comprises a disc which is rotatable about its axis, with machining elements which are provided on the periphery thereof and the cutting edges of which lie in the outer surface of a profile determining the shape of the teeth of a crown wheel to be produced with the tool, said profile extending essentially helically over the periphery of the disc. In each cross-section of the helical profile the outer contour (25) of the cross-section is at least of a part of the outer contour of the tooth profile of an imaginary gear wheel (23) with involute teeth and preferably straight lines connecting thereto, in such a way that in the case of each of the teeth (22) with a tooth tip and two tooth flanks bounded by the outer contour (25) of the cross-section the distance between each of the two tooth flanks and a line at right angles to the axis of rotation of the tool and passing through the tooth tip remains the same or increases from the tooth tip to the axis of rotation of the tool.

摘要： A tool for manufacturing crown wheels by means of a machining hobbing process, which consists of a disc which can rotate about its axis and on the circumference of which machining elements are disposed whose cutting edges lie in the surface of a profile which mainly extends over the circumference of the disc as helical ribs. In each cross-sectional plane perpendicular to the screw direction of the ribs, the profile has the shape of a number of profile teeth situated next to one another. The profile shape is based on the base geometry of a pinion which is characteristic for the crown wheel to be manufactured and has involute toothing. The profile has such a shape that a part thereof lies outside the surface of revolution which is formed by rotation of the addendum circle of the characteristic pinion about the rotational axis of the tool. As a result, the tool has machining elements or machining element parts whose cutting edges lie in the surface of the portion of the profile outside the surface of revolution formed by rotation of the addendum circle and can serve for performing a premachining operation when manufacturing a crown wheel.

摘要： Crown wheels (21) are ground on a grinding machine with the aid of a hobbing grinding disc (11) of ceramic material which is formed on the same grinding machine with the aid of a dressing crown wheel (13) with one or more teeth (14) provided with a dressing material such as diamond. The shape of said crown wheel tooth or teeth is in principle the same as the shape of the teeth of the crown wheel to be ground. The hobbing grinding disc (11) is mounted on the grinding wheel shaft (12) of the grinding machine both during its formation and during the grinding of the crown wheels, while the dressing crown wheel (13) or the crown wheel (21) to be ground is mounted on the workpiece holder (15) of the grinding machine. During the formation of the hobbing grinding disc (11) or the grinding of the crown wheels (21) the movements of the hobbing grinding disc relative to the tooth or teeth (14) of the dressing crown wheel (13) provided with a dressing material or the crown wheels (21) to be ground are in principle the same. The shape of the tooth or teeth (14) of the dressing crown wheel is consequently always transferred in the same way by means of the hobbing grinding disc to the teeth of the crown wheels to be ground. Crown wheels can be ground very accurately in this way.

摘要： A hob cutter (4) for machining face or crown gears comprises a disc-like cutter body having an axis of rotation (6) and a number of hob teeth groups (1, 2, 3, . . . ) which are uniformly distributed over the circumference and which are each bounded at the front by a cutting face (S) and at the cirumferential side by a clearance face (V). The cutting face and the clearance face of each hob teeth group intersect one another in a cutting edge (9) which determines the shape of the face gear to be machined. The clearance face of each hob teeth group is made up of a number of generatrices (L, m) which are each situated in a machining plane which is determined by a line which intersects or crosses the axis of rotation (6) perpendicularly and intersects the generatrix at the position of the cutting edge. The extensions of the generatrices (L, m) determining the clearance face run at a minium spacing over the outside of the downstream hob teeth group.

摘要： Transmission unit for driving two parallel shafts, at least one shaft being movable at right angles to its lengthwise direction, for example for a rolling mill (1). In this case each shaft (8, 11) is provided with a crown wheel (14, 15) which meshes with a cylindrical pinion (16), each pinion having a shaft (17) of which the axis intersects or crosses the axis of the shaft belonging to the crown wheel at right angles, and the rotations of the pinions being interconnected with a fixed transmission ratio. The cylindrical pinions can be fitted on one common shaft which can lie in the plane through the axes of the two shafts or at a fixed distance parallel to said plane, independent of the movement of one of the shafts or both shafts. Two pinions can be combined to form one pinion.
