| 20090125138 | METHOD AND APPARATUS FOR THE FREE-FORM OPTIMIZATION OF BEVEL AND HYPOID 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. | 05-14-2009 |

| 20110262238 | Method for Producing Bevel Gears Having Hypocycloidal Teeth in the Continuous Indexing Method Using a Corresponding Face Cutter Head - 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. | 10-27-2011 |

| 20090026038 | ESCALATOR OR TRAVELATOR - An escalator or travelator comprising a circulating step belt or panel belt. Each step or panel of a belt is provided on each side respectively with a supporting roller and a chain roller, which are guided on supporting roller rails and chain roller rails in forward travel and in return travel. Supporting roller return travel rails are adapted to support the supporting roller only partially. | 01-29-2009 |
