Preserve the evidence
Keep both mating members, broken fragments, spacers, shims, bearings and assembly photographs. Mark orientation and avoid altering surfaces before inspection.
Document the assembly
Record shaft angle, mounting distances, bearing arrangement, rotation, backlash, lubricant and machine function.
Measure and reconstruct
Capture datums, bore and mounting features, tooth counts, spiral hand, face width, cone geometry, runout, hardness and visible wear. Measurements from worn flanks must be interpreted rather than copied blindly.
Validate the first set
Inspect dimensions, material, hardness, pair identification, backlash and contact at the approved mounting condition. For uncertain or critical projects, use controlled first-off field validation before repeat production.
Frequently asked questions
Can reverse engineering bevel gears be developed from an existing sample?
A sample can support dimensional study, but the most reliable route also includes the mating member, shaft angle, mounting information, speed, torque, material or hardness information and failure history.
What information is required for quotation?
Provide a dimensioned drawing or sample, quantity, module or diametral pitch, tooth counts, pressure angle, spiral hand where applicable, ratio, material, heat treatment, accuracy requirement and expected duty.
Can one member be replaced without the mating gear or pinion?
It may be possible after inspection, but a matched-pair approach is normally preferred because tooth contact, backlash and mounting are interdependent.
How is delivery time determined?
Delivery depends on geometry, quantity, material availability, tooling, heat treatment, finishing, inspection scope and technical approval.
