Gearbox Shaft Manufacture

Gearbox Shaft Manufacture

Up to 800 mm long, straight or helical — the broken original is pattern enough

Our gearbox shafts are machined from a single piece of high-strength steel, heat treated and cut on our own machines — up to 800 mm long, straight or helical. The old part is pattern enough, even broken.

Length
up to 800 mm
Teeth
straight or helical
Construction
one piece, heat treated
Ground tolerance
down to 0.0025 mm

Sizes and limits

Teeth are cut up to 500 mm diameter and module 8, straight or helical; shaft lengths up to 800 mm. Turning is done on the Seiler SLZ 570 CNC lathe up to 500 mm turning diameter and 500 kg between centres, and conventionally up to 600 mm diameter and 1800 mm long. Ground teeth are produced down to a tolerance band of 0.0025 mm, with a measurement report accompanying the part on request.

Material

What matters is not the material designation but the construction: our shafts are machined from one piece — not welded, not joined — and then properly heat treated. Material and treatment are chosen to suit the function, and for uprated engines they are calculated for the real load rather than the production reserve. If your drawing specifies the material, we work to it.

How it works

  1. Send in the shaft or the drawing. A broken shaft is usable as a pattern as long as the teeth can be measured. For shipping, see send in your gearbox.
  2. Measuring. Lengths, bearing seats, tooth data and material requirements.
  3. Drawing. A CAD drawing in DWG or DXF format — the drawing stays with you.
  4. Manufacture. Turning, gear cutting, heat treatment, grinding and a measurement report on request. For gearboxes sent in to us we fit the shaft and carry out the related setting work.

Where the 0.0025 mm comes from is easiest to show on the best-known part in our programme: the 8:35 final drive for the Porsche 915 gearbox is ground in both directions instead of hobbed and lapped, every set is numbered, and every set has a measurement report. A shaft made to drawing is produced on the same machines.

Price and lead time come with the quotation. Both depend on length, tooth form, material and whether the part is ground — a figure without those details would be a shot in the dark.

Typical problems this solves

  • The shaft has broken at the teeth and is no longer available
  • More power exceeds the reserve built into the production shaft
  • Design office, machine shop, heat treatment and grinding would otherwise each have to be commissioned separately

Inquiry

What is on your bench?

Gearbox type and a few lines about your request — that is all we need for a first assessment. A photo helps but is not required. The answer comes from the machinist, not from sales.
