Cone Drive Gearbox Repair in Fontana

Cone Drive built its reputation on worm gearing — including the double-enveloping designs that carry heavy loads in compact housings for slew, lift and process drives. That geometry is unforgiving of approximate repair. Our Fontana shop rebuilds Cone Drive gearboxes in-house with the mesh treated as the precision system it is: worm and wheel measured together, contact and backlash assessed honestly, and replacement wheels cut to the correct enveloping profile in our own gear shop.

Single and double-enveloping worm drives, measured as a set

A worm drive's wheel and worm wear as a matched pair, and the bench reads them that way: throat and tooth condition on the wheel, thread profile and shaft condition on the worm, bearing fits and housing alignment behind both. A wheel cut to a generic profile will run hot, wear fast and never carry rated load quietly — so where renewal is needed, the new wheel is manufactured to the geometry the original pair was built with, then set up with correct center distance, backlash and contact pattern on assembly.

Frequently asked questions

Can you cut a new wheel for a Cone Drive double-enveloping gearbox?

Yes — manufacturing worm wheels to the correct enveloping geometry is exactly the kind of gear work our shop exists for. The worn pair is measured first so the new wheel matches the drive's original geometry.

Why does my worm gearbox run hot after a previous repair?

Heat usually means the mesh geometry is wrong — an incorrectly profiled wheel, wrong center distance or bad contact pattern. We assess the pair at teardown and correct the geometry, not just the worn part.
