Design the gear train the catalog does not have.
Custom gears, complete gear trains, and entire gearboxes. Designed, prototyped and carried into production by engineers who have set up the hobbing machines, run the presses, and measured the results.
- Best fit for
- A mechanism whose ratio, envelope, noise or backlash cannot all be met by a catalog gearhead, an obsolete gear or gearbox with no successor, or a train that exists only as a requirement.
- What to send
- The envelope, the input and output conditions, and whatever exists today: a drawing, STEP geometry, the failing part, or two sentences and a sketch.
- What you receive
- A written feasibility read first: catalog, configured, or custom. Then a proposed train, with ratio architecture, gear geometry, materials, and the tolerances with the metrology to prove them.
- Response time
- Written feasibility read within two business days. Proposal and prototype timing are scoped in writing before any work is quoted.
Three sizes of custom
The work scales to the problem. A single replacement gear, the complete reduction, or the whole assembly with its housing.
The deliverable is a specification another engineer can check
A custom gear train is not a black box with a ratio on it. Every proposal states its geometry, its tolerances, and how each one will be measured.
- Tooth geometry
- Module or diametral pitch, tooth counts, pressure angle, helix, face width, and the profile shift at each mesh. Stated, not implied by a CAD export.
- Quality class
- Accuracy to AGMA 2015 or ISO 1328, chosen mesh by mesh for what the function needs rather than one blanket class the price then carries.
- Backlash budget
- Center distance tolerance, tooth thinning and runout allocated across the train, so the assembly meets the number without selective fitting.
- Materials and heat treatment
- Alloy, hardness, and case depth where called for, with the distortion allowance the finishing plan has to absorb.
- Metrology plan
- How each control is verified: measurement over pins or across a span, double-flank roll testing, and what accept and reject mean at the bench.
- The production route
- Which operation produces each feature, hobbed, shaved, molded or powdered metal, because a drawing is only honest if the process can hold it.
If a catalog train closes the requirement, that is the answer.
Custom tooling costs real money and real calendar. Every review starts by testing the requirement against the published catalog and its configurable options, and custom work is proposed only where the requirement, the volume and the timeline actually support it.
From requirement to qualified train
Four stages. The first is free, and each of the rest is scoped and quoted in writing before it starts.
-
Requirements review
The envelope, ratio, loads, duty, noise and backlash targets, volumes and timing. It ends with a written feasibility read: catalog, configured, or custom. If catalog closes it, that is the recommendation.
-
Geometry and train proposal
Ratio architecture and stage layout, the full gear specification, and the cost drivers named one by one: which tolerance, which material, which operation.
-
Prototype path
Machined or short-run tooled parts that prove the mesh, the noise and the assembly before production tooling is committed.
-
Qualification
Backlash, noise, efficiency and life measured against the stated targets, documented so your quality system can accept the result.
