Internal gear tooth

Internal gear tooth

A gearwheel with internal toothing ensures maximum use of space with increased strength

Our gearwheels with internal toothing enable high torques to be transferred even under precise, almost clearance-free assembly conditions. Internal gear tooth systems are often used in planetary gearboxes, variable speed gearboxes or oil pumps.

  Module Diameter
Internal gear tooth 0,5 -10 approx. 25/30 to 900 mm (depending on the number of teeth and the module)

Smaller diameters can be produced with profiled broaches. Can also be produced in quality 6 (up to 450 mm).

Our high-precision internal gear tooth systems and ring gears are made possible through the use of various different procedures.

One of the basic procedures is gear hobbing. It involves the slotting tool rolling continuously on its own axis, like a planetary wheel in a ring gear. In addition to the rolling motion the slotting tool also executes a lifting motion, which means that material is only removed when struck. And in a third type of motion, the slotting tool moves radially into the work piece material in order to attain the required tooth thickness on the work piece. This creates the desired toothing.

We not only produce running gears according to DIN 3962/67 but also involute splines according to DIN 5480, DIN 5481 and DIN 5482. To produce this large range we keep a multitude of tools and collets in readiness for your components.
