Palloid toothings emerged from a development during the twenties in which straight toothing experienced a technical advancement in the form of helical toothing. The toothing is formed by means of a conical gear hobbing mill in a continuous process. Extremely high pitch accuracies are achieved by the combination of continuous sub-processes and a single-speed tool. This guarantees high contact ratios, extensive insensitivity to displacement, and assurance of the best possible running smoothness. The parallel tooth root has very large fillet radii which has a positive effect on the fracture strength (longevity) of the gear wheel set.

Whether you want special machinery with a 280 mm diameter or a large 7mm component for a medical device - the potential applications of spiral bevel gears are as varied as the demands put on them. Spiral bevel gears are a particularly good solution when the maximum torque has to be re-routed in a different direction with minimum losses in a confined space.

lexible shafts are extremely rugged, high-longevity components that permit continuous work operations even in high speed ranges (up to 50 000 rpm). For substitution of unprotected or complex drive units (angle gearboxes, chain hoists universal joints, etc). angle gearboxes chain hoists universal joints

The Cyclo-Palloid hobbing method fulfills the high requirements on the running smoothness and on the gearset motion transmission uniformity (active noise reduction). This manufacturing process provides all prerequisites for high manufacturing quality, and is also equally suitable for small, medium and large series production. As is the case with the palloid toothing, the Cyclo- Palloid toothing is produced in a continuous hobbing process. Individual cutting heads permit free selection of the module Mn and afford very high flexibility in design and calculation of the bevel gear train. Hypoid toothings are also possible.

The new “HPGS hard cut” technology was developed on the basis of the proven Cyclo-Palloid hobbing process (regular hobbing method). In a further operation the distortion resulting from heat treatment is eliminated by means of boron-nitride-coated cutters. With this fine machining following the heat treatment, very high surface finishes are achieved to more than fulfill the higher requirements of today’s power gear trains. HPGS helical tooth bevel gearwheels exhibit substantially higher flank loading capacity, substantially better running smoothness and a predefined contact pattern. The tooth flank surface values achieved are equivalent to those of grinding quality, and the toothing finishes can achieve between 4 and 6 according to DIN 3965.
