For special applications, an alternative gear geometry can be produced using the free-form milling process. The pitch accuracy is absolutely sufficient for most applications. A big advantage is certainly the surface quality and the geometry of the tooth flank, which can be freely designed.
Free-form production is used for
herringbone gears (including double helical gears) and for other more complex
tooth geometries. We would be happy to advise you on the best possible design.
axial force component of the double helical gearing can be virtually eliminated
by the symmetrical arrangement of the mirrored helical gearing. Due to the use
of herringbone gearing, which is complex to manufacture, a left-hand and a
right-hand part are combined on one gear.
