Cyclo-Palloid Hobbing

The cyclo-palloid hobbing method fulfils the highest requirements on smooth running and the uniformity of the gearset’s motion transmission

This manufacturing process assures all prerequisites for high manufacturing quality and is equally suitable for implementation in single, small or large batch production. As with palloid toothing, cyclo-palloid toothing is also created using a continuous hobbing process. Individual cutting heads permit free selection of the Mn module and provide very high flexibility in designing and calculating the bevel gear train. Hypoid toothing is also available as an option.

 

Characteristics of cyclo-palloid toothing    

  • Freely selectable Mn module
  • Constant tooth height
  • High contact ratio
  • High pitch accuracy
  • Insensitivity to displacement
  • Stepless variation of tooth longitudinal crowning
  • Selectable helical angle

HPGS Cyclo-Palloid Hard Cut

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. Implementing this fine machining operation after heat treatment achieves very high surface finishes that more than fulfil the ever increasing requirements of today’s power gear trains. HPGS helical-tooth bevel gearwheels exhibit substantially higher flank loading capacity, substantially improved running smoothness and the option of designing the contact pattern in a targeted manner. The tooth flank surface values achieved are equivalent to those of grinding quality, and the toothing finishes can achieve ratings between 4 and 6 according to DIN 3965.

Characteristics of HPGS cyclo-palloid toothing    

  • Very high toothing quality
  • Higher flank loading capacity
  • Significantly improved running smoothness
  • Targeted design of contact pattern
  • Freely selectable Mn module
  • Constant tooth height
  • High contact ratio
  • High pitch accuracy

Possible Applications

Power tools

Angled gearboxes with spiral bevel gears are at the very heart of every handheld power tool that is operated continuously, at peak load or at extreme temperatures, or frequently subjected to strokes and blows.

CNC angle heads

As components critical for quality, angled gearboxes with spiral bevel gears are at the core of many CNC angle heads that are in use today. They stand the test at the highest acceleration, during torque changes, under wet conditions as well as in continuous operation.
