The present disclosure relates to a process for machining a gear workpiece () comprising a plurality of tooth spaces (), each of which is defined by two tooth flanks (); in said process, a gear tooth-forming tool () is used in order to provide at least one subset of all the tooth flanks () with a non-periodically distributed modification of the flank geometry.

Process for machining a gear workpiece, and corresponding pair of gears

An apparatus including a first spindle group for chucking a first gear, whereby the first gear is mountable on the first spindle group so that it is rotatable, and a second spindle group for chucking a second gear, whereby the second gear is mountable on the second spindle group so that it is rotatable. The apparatus further defining a first linear axis oriented to perform a first linear displacement of the first spindle group relative to the second spindle group; a second linear axis oriented to perform a second linear displacement of the first spindle group relative to the second spindle group; and at least one of a swivel axis oriented to perform pivoting of the first spindle group thereabout, and a swivel axis oriented to perform pivoting of the second spindle group thereabout.

Apparatus for the lapping or testing of gears

A method for grinding bevel gears (), wherein a first grinding tool () is used during a first method section and a second grinding tool is used during a second method section. A measurement system () is used to carry out a measuring procedure, in which sampling values can be ascertained for at least a part of first flanks of the bevel gear workpiece (), which enable a statement about the concentricity error of this bevel gear workpiece () in the present chucking. Concentricity correction dimensions are ascertained by computer on the basis of the sampling values, and an adaptation of machining movements of the second method section is performed on the basis of the concentricity correction dimensions.

Method for grinding machining of bevel gears in the single-indexing method

The invention relates to a method for hard fine machining of a pre-manufactured flank () of a gear wheel by a machine having at least five axes controlled in coordination and one additional tool axis (WA). According to the invention, a rotation-symmetrical tool () is driven on the machine side such that it is set into a rotation (RA) about the tool axis (WA). In addition, the axes controlled in coordination are actuated such that a straight-lined section of the surface line of the tool () is guided tangentially along the flank () in a generating movement while the tool () removes material on the pre-manufactured flank () by means of the rotation (R) about the tool axis (WA). The generating movement follows pre-specified movement vectors (E).

Method for hard fine machining of the tooth flanks of a gear wheel

A face milling cutter method for manufacturing various hypocycloidal bevel gears that is characterized in that the following steps are performed to manufacture a first bevel gear: equipping a universal face milling cutter in a first configuration with a first number of cutter groups that corresponds to a first number of passes. A first bevel gear is then produced in the continuous partial method using the universal face milling cutter in the first configuration. The following steps are performed to manufacture a second bevel gear: equipping the same universal face milling cutter in a second configuration with a second number of cutter groups that corresponds to a second number of passes. The second bevel gear is then produced in the continuous partial method using the universal face milling cutter in the second configuration.

Method for producing bevel gears having hypocycloidai teeth in the continuous indexing method using a corresponding face cutter head

The invention relates to a device for green machining bevel gears, including a CNC machining station for gear cutting a wheel blank (K). The machining station includes 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 (K). The machining station also relates to a machining station which operates in a vertical manner. The 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 (K). The machining station mechanically forms a functional unit together with the pre-machining station, wherein the work piece blank (K) undergoes green machining in the pre-machining station, and is transferred as a gear blank (K) to the first machining station after the first green machining where it is cut into a gear. The machining station and the pre-machining station are linked together in terms of data and control.

Device and method for green machining bevel gears

A device () for measuring the running behavior of a gear pair having a rolling device () which comprises one spindle () per gear () and has at least one drive () for driving one of the gears (). Furthermore, a structure-borne noise sensor (), a sequence controller (), and a speed sensor system () are provided. The sequence controller () is designed in such way that a combined test of the gear pair may be performed, in which, in a first search run, a specific installation position is ascertained using structure-borne noise testing and subsequently a single-flank working test is performed at the specific installation position.

Device and method for combined testing of gears

Method for the optimization of the surface geometry or of a variable, dependent on this, or variables, dependent on this, of bevel or hypoid gears for their production on a free-form machine which can be mapped to a free-form basic machine with at most six axes uniquely in a reversible way, even to symmetries, which has a gearwheel to be machined and a tool which are in each case rotatable about an axis, and the tool and the gearwheel to be machined are moveable, preferably displaceable or rotatable, with respect to one another along or about a plurality of axes, the optimization of the surface geometry or of the variable or variables, dependent on this, of the bevel or hypoid gearwheel taking place in that one or more control parameters, which has or have influence on the surface geometry or the variable or variables, dependent on this, of the bevel or hypoid gearwheel, is or are varied by means of a simulation of the gearwheel production process and/or a roll and/or a load-contact analysis on the free-form basic machine, until the surface geometry or the variable or variables, dependent on this, of the bevel or hypoid gearwheel thereby corresponds at least to a predetermined target value.
