Materials for precision gears

Define a material solution for the transmission through tooth accuracy, loading and friction, together with lubrication, temperature, noise and service-life requirements.

Application parts: Precision transmission gears, gear sets, shaft bores and mating interfaces
Material system: Confirm matrix, reinforcement and functional formulation for the part requirements

APPLICATION / REQUIREMENTS

Define the material through the part requirements.

Transmission & loading
Define module, tooth profile, torque, speed and shock loads; distinguish continuous and intermittent duty.
Friction & lubrication
Confirm the mating material, lubrication, contact chemicals and wear criteria.
Dimensions & fit
Verify tooth geometry, shaft-bore fit and noise targets against shrinkage, conditioning and temperature changes.

PART / PROCESS / VALIDATION

Confirm performance with the actual part.

Confirm the grade, part drawing and equipment before drying, molding and part trials; use formal documentation and trial results for processing parameters.

Geometry: inspect tooth profile, concentricity, shaft bore and mating tolerances against the drawing.
Operation: assess wear, temperature rise and noise under the actual load, speed and lubrication.
Lifetime: record cycles, failure modes and environmental condition against transmission-life requirements.
