摘要： A method for deburring an internally toothed workpiece includes providing a workpiece and a deburring tool. The workpiece has an inner toothing produced by hob peeling, with first and second tooth flanks. The deburring tool has a first cutting plate and a second cutting plate, diametrically opposed to the first cutting plate. The method includes rotating the workpiece in a first rotating direction and deburring the first tooth flanks with the first cutting plate while the deburring tool is not rotating. The method also includes shifting the deburring tool relative to the workpiece such that the first cutting plate and the second cutting plate do not contact the workpiece, rotating the workpiece in a second rotating direction, opposite the first rotating direction, further shifting the deburring tool relative to the workpiece, and deburring the second tooth flanks with the second cutting plate while the deburring tool is not rotating.

摘要： A gear machining apparatus includes: a hob cutter; at least one processor; and at least one memory having instructions. The instructions, when executed by the at least one processor, cause the gear machining apparatus to perform operations including: performing first chamfering on a first axial end of a gear profile by relatively moving the hob cutter with respect to a workpiece in radial and axial directions of the workpiece; performing, subsequent to the first chamfering, gear profile machining by relatively moving the hob cutter with respect to the workpiece in the axial direction; and performing, subsequent to the gear profile machining, second chamfering on a second axial end of the gear profile by relatively moving the hob cutter with respect to the workpiece in the radial and axial directions.

摘要： The invention relates to a method for producing a removal of material on a tooth end edge of a workpiece toothing with a rotationally driven chamfering tool in a machining operation brought about by controlled axial machine movements between the chamfering tool and the likewise rotationally driven workpiece toothing, wherein material is removed with a geometrically undefined cutting edge and the removal takes place in a coordinated action between a profiling, in particular, an alterable profiling, of the chamfering tool and a machine control used for the machining operation, performed in dependence on predetermined parameters that are characteristic of the removal of material to be produced.

摘要： A method wherein a cutting or grinding chamfering tool (25) is guided along the face width of a gear (12, 23, 52) through one tooth slot (8) (e.g. from heel to toe) while it contacts the topland corners (10, 1 1) of the respective concave and convex tooth flanks of adjacent teeth (2, 4). The tool moves to an index position, the gear is indexed to the next tooth slot position and the tool moves through the tooth slot (e.g. from the toe to the heel). The cycle is repeated until all topland corners are chamfered.

摘要： A method and apparatus for processing a metallic workpiece with defined edges (e.g., a gear) comprises media blasting of the workpiece by directing a first media against exposed surfaces on the workpiece to increase the root strength of the gear, the blasting causing the defined edges to be radiused or mushroomed, ceasing the media blasting, loading the workpiece into a finishing apparatus, and subjecting the workpiece to a finishing process with a second media, the exposed surfaces on the workpiece being subjected to the finishing process to reduce the radiused edges on the workpiece created from the media blasting. The process of moving the workpiece to the spindle-finishing apparatus from the media blasting may be performed automatically by a machine. Once the workpiece has been subjected to the finishing process with the second media, it may be removed from the spindle-finishing machine, washed, and rinsed with rust inhibitor whereby wear properties of the workpiece are enhanced.

摘要： A method for producing gears, wherein in a first step a set of teeth is formed by means of a skiving wheel rotationally driven by a tool spindle in a workpiece gear rotationally driven synchronously thereto by a workpiece spindle, wherein the workpiece spindle and the tool spindle are at an axis intersection angle to each other and the advancement occurs in the tooth-flank extension direction, and wherein in a second step at least some teeth of the set of teeth are machined by means of a tooth-machining tool. A combined tool is used, in the case of which the toothmachining tool and the skiving wheel are fixedly connected to each other. Between the two steps, the combined tool remains connected to the tool spindle and the workpiece gear remains connected to the workpiece spindle. Between the two steps, merely the relative position of the tool spindle in relation to the workpiece spindle and the rotational speed ratio of the two spindles are changed.

摘要： A motion which creates an end relief and which is integrated into the plunging cycle of non-generated bevel gears. The tool, after feeding to the correct tooth forming position in case of non-generated gears, is swung sideways out of cutting or grinding contact with the slot instead of along a withdraw path which is identical to the plunge path but opposite in direction.

摘要： A method and apparatus for driving a wire conveyor belt with a buildup shedding sprocket. When driving a belt in any application in which material is added to articles on the belt, excess material accumulates on the support shelves between the sprocket teeth. A relief cut is made between the sprocket teeth providing a channel through which the excess material can be pushed away.
