Abstract: A treatment system for the surface treatment of workpieces, particularly vehicle bodies, includes a plurality of transport devices, on which at least one workpiece to be treated can be attached in a releasable manner. A conveying device moves the transport devices through the treatment system. At least one treatment bath is disposed in a first conveying plane of the treatment system and the transport devices with the workpieces arranged thereon are introduced into the treatment bath. At least one cleaning device, which is suitable and designed for cleaning the transport devices after the surface treatment of the workpieces, is disposed in a second conveying plane of the treatment system. The second conveying plane is offset in the vertical direction relative to the first conveying plane.

Abstract: A grinding worm for the continuous generation grinding of a work piece is provided with mutually overlapping rough grinding and finish grinding zones arranged along the worm's axis, the finished grinding zone being provided with a three-dimensionally modified flank geometry having a width related design.

Abstract: In a process for the profiling of a grinding worm (1) with at least two grinding width zones (4, 6) with differently modified thread profile for the grinding of spur and helical gears with three-dimensionally modified flank profile, the grinding width zones (4, 6) are arranged overlapping in order to gain optimum exploitation of the grinding worm width (3). In one variant, profiling of the grinding worm (1) is performed with an abrasive coated profiling gear (25) with a tooth flank geometry and facewidth differing from that of the workpiece to be ground. By suitable selection of the diagonal ratio and the allocation of the width zones (28, 29) of the profiling gear (25) to the grinding width zones (4, 6) of the grinding worm (1), it is possible to adapt the modifications of the grinding worm flanks to the requirements of the workpiece without having to alter the flank geometry of the profiling gear (25).

Abstract: Method and an apparatus for the profiling of single-gear or multiple-gear grinding worms for grinding tooth profiles in accordance with the principle of continuous diagonal generating grinding. A grinding worm is divided into at least two axial zones wherein one zone remains unmodified and a second zone receives, by means of special profiling methods, modifications of the thread flanks for the generation of tooth flank modifications The main attribute of these profiling methods is additional movements, which are superimposed on the disk-shaped profiling tool and/or the grinding worm in relation to a given profiling shift position, and which result in the modifications of the grinding worm flanks that are mapped onto the flanks of the toothed wheel work during subsequent diagonal generating grinding across a grinding worm zone profiled in this manner.

Abstract: Method and an apparatus for the profiling of single-gear or multiple-gear grinding worms for grinding tooth profiles in accordance with the principle of continuous diagonal hob grinding. A grinding worm is divided into at least two axial segments wherein one segment remains unmodified and a second segment receives, by means of special profiling methods, modifications of the spiral faces for the generation of tooth face modifications. The main attribute of these profiling methods is additional movements, which are superimposed on the disk-shaped profiling tool and/or the grinding worm in relation to a given profiling lift position, and which result in the modifications of the grinding worm faces that are mapped onto the faces of the toothed wheel work during subsequent diagonal hob grinding across a grinding worm segment profiled in this manner.

Abstract: The invention relates to a method for the profiling of single-start or multistart grinding worms for profile grinding of gear-teeth according to the principle of continuous generating grinding. The goal of the proposed profiling principle is to position the profiling tool and/or the grinding worm in relation to each other in such a way that different areas of an axial section of the grinding worm thread (referred to as shape elements) can be profiled with different geometric elements of the active area of a profiling tool (referred to as tool elements). According to the invention, for this purpose, with the aid of a coordination matrix a tool element is coordinated with each shape element of an axial section of the grinding worm thread. The coordination criteria applied in this regard are, in particular, short profiling time and flexible changing of the shape elements.
