            • The bevel gears of Nidec Graessner

            • Advantages of Spiral, Hypoid and Zerol® Bevel Gears

              • High level of coverage due to the fact that several teeth are meshed simultaneously
              • Resistant to elastic deformation of gears, shafts and bearings
              • Circular arc gear teeth are more resistant to bending than straight and oblique gear teeth
              • Very gentle transmission even at high-speed operation and under heavy load
              • Noise and oscillation damped even at high peripheral speeds
              • Gear sets can be assembled in your preferred direction of rotation
              • > 97% efficiency depending upon layout and lubrication
              • Due to convex tooth-loading the load is not concentrated on the tooth-ends
              • All gear sets can be lapped in pairs upon request

              Spiral bevel gears
              • With circular arc teeth.

              Hypoid bevel gears
              • Similar to spiral bevel gears, but with the drive pinion axially offset either above or below. This means a greater pinion diameter, longer life and more gentle tooth meshing.

                              • TorusGear

                              • The planar spiral gearbox
                                TorusGear Planar spiral gearboxHighest possible quality and precision, limited weight, simple construction and minimal space requirement makes the TorusGear highly efficient.

                                With the TorusGear a new and unique gearbox was developed and patented. This new and unique gearbox has excellent characteristics compared to existing gearboxes.

                                One gear step is the Torus wheel with spiral shaped tooth and the curve wheel with the curved tooth shape. The contact surface and the load on the material can be substantially reduced with the novel gearing module.

                                The TorusGear is the first „Planar-Spiral Gear“ which is technically mature to be used for industrial applications.

                                Characteristics
                                The technical superiority of the TorusGear compared to conventional gearboxes can be described as follows:

                                Efficiency
                                The efficiency remains, irrespective of the gear ratio, almost constant. This means that the TorusGear reaches at high gear ratios, above 100:1, a substantial higher efficiency, compared to the worm gear, where the efficiency factor reduces with increasing gear ratios.

                                High Gear Ratios
                                With worm gearboxes, high ratios can only be realised with multiple gear stages or motors with low speeds (750 rpm or 1000 rpm), or a combination of the two options. Additional gearbox stages have a negative influence on the level of efficiency, and require more components, the immediate results of which are lower efficiency and higher costs. The same applies to the option of motors with lower speeds. Electric motors with speeds of 750 rpm or 1000 rpm are respectively approx. 250% and 160% heavier, and cost almost 99% and 33%, respectively, more than an electric motor with a speed of 1500 rpm. At an input speed of 750 rpm and a ratio of 200:1, a worm gearbox achieves the same output speed as a TorusGear with an input of 1500 rpm and a ratio of 400:1.

                                Accuracy
                                The unique design of the TorusGear simplifies the adjustment or elimination of backlash. A built in spring preload eliminates backlash for life time.

                                High Operational Reliability
                                The low number of moving parts increases the operational reliability. Safety related functions can be maintained after a tooth break, as several teeth are meshing at the same time on the TorusGear.

                                    When our products are used in the machine-tool field, everything revolves around the highest switch-on times with the highest rotational speeds. And for these special requirements we have very special solutions.

                                    Precise, high-torque and fast – the feed drives in the machine tools are designed, among other things, with our straight bevel gear pairs – also as a master-slave combination that includes a toothed rack. This guarantees high levels of stiffness and dynamics.

                                    The auxiliary drives of the machine tools are as varied as they are demanding: during processes such as sawing, drilling, milling, planing, pressing, grinding, machining and finishing – to mention just a few – clamping, rotating and centring must be efficient. Our experienced engineers find an optimum solution here. This is also confirmed by a large number of references from well-known customers. Incidentally: our engineers are also happy to work together with customers or according to a requirements specification sheet to develop special solutions for machine-tool construction. Because we love a challenge
