Gear hobbing

Hob cutters generate spur and helical gears for gearboxes, pumps, machinery and vehicles.

What was needed
Involute Hob Cutter, Preground Hob Cutter, Non Standard Hob Cutter
Requirements
  • Accurate tooth form
  • Economical in batch and volume
  • Standard and special profiles
Result
Accurate gears at production rates, from one hob per module.

Problem

Gears for transmissions, gearboxes and drives must have an accurate tooth form for smooth, quiet running and long life, and must be produced economically in batch and volume.

Solution

Hobbing generates the tooth form continuously as the hob and the gear blank rotate together. One hob cuts all tooth counts of the same module and pressure angle.

  • Involute hobs for standard spur and helical gears; non-standard hobs for special profiles.
  • Pre-grind (pre-shaving) hobs leave a controlled stock for finishing by grinding.
  • Malkar uses the same hobs in its own gear production.

Benefits

Why it works

Productive

Continuous cutting suits batch and volume production.

Accurate tooth form

Precision-ground hob profiles.

Flexible

One hob covers many tooth counts of the same module.
