Abstract: The invention relates to a device for green machining bevel gears, comprising an CNC machining station for gear cutting a wheel blank (K2). The machining station comprises a tool spindle which is used to receive a gear cutting tool and a work piece spindle which is used to receive the gear blank (K2). Said machining station also relates to a machining station which operates in a vertical manner. Said device also comprises a vertical processing station having a tool holder and a work piece spindle which is used to receive a work piece blank (K1). The machining station mechanically forms a functional unit together with the pre-machining station, wherein the work piece blank (K1) undergoes green machining in the pre-machining station, and is transferred as a gear blank (K2) to the first machining station after the first green machining where it is cut into a gear. Said machining station and the pre-machining station are linked together in terms of data and control.

The transition between each ridge (210) and an adjacent trough (220) in the same row (200) is formed by a transition portion (230) which is inclined relative to the central plane (P1) of the plate (1). The heat transfer plate is used in a plate pack for a plate heat exchanger.

Abstract: In a method and apparatus for machining spiral bevel gears a rotationally symmetric tool is driven about its axis of rotation as it is moved, along with a workpiece, into a respective initial starting position. The workpiece is rotated about one tooth index, and a complete tooth space is processed via a generating method to a preset generating depth. The tool and workpiece each reach first end roll positions and are then moved into respective second starting positions near the previously reached end roll position. The workpiece is once again rotated about a tooth index and another complete tooth space is generated using a roll direction reversed relative to the initial tooth generating process. The tool and workpiece reach a second end roll position near the first start position and these steps are repeated until all the tooth spaces of the workpiece have been processed.

Abstract: A gas-jet driven rotary device is provided which, when being operated, creates a field which may be utilized to treat a variety of electrical, chemical, and mechanical systems, device and/or components for increased performance gains. The device includes a wheel-like rotor mounted between parallel walls defining part of a housing capable of being hermetically sealed such that a vacuum may be formed within the housing. One feature of the rotor is the structure forming the arcuate segment of the passageway around the shaft, which includes a flexible inner tube centered concentrically within a rigid outer tube or conduit of larger diameter. The annular space between the inner and outer tubes is in communication with the atmosphere. To power the rotary device, compressed gas is fed to it through the inlet opening into the passageway. The gas flows through the passageway and out the exit port in the form of a jet which imparts thrust to the rotor and causes it to spin.

Abstract: This invention refers to a supporting structure (10) for sheet material as sheet metal material (100) cut out by a laser device (200) located above the sheet material and focused on the same, with means of movement between the laser device and the sheet material and/or supporting structure. The supporting structure substantially comprises vertically mounted parallel rows of identical narrow sheet strips (12), each having raised integrated support areas (22) for the sheet material (100) between recessed grooves (20). To increase the life time of the sheet strips and therefore the life of the supporting structure, and at the same time to prevent damage to the underside of the sheet material as sheet metal, needles (24) are set onto the integrated support areas (22) of the sheet strips (12), the free ends of which form points of support (26) for the sheet material (100) laid upon them.
