Practical answers for buyers specifying a powder metallurgy gear, including material choices, custom drawings, tolerance formats, treatments, applications and quotation details.
A powder metallurgy gear is specified through its material, tooth geometry, dimensions, tolerance, treatment and intended application. A CAD drawing, 3D model, PDF drawing or sample gives the supplier a starting point for reviewing a custom part.
What materials are available for a powder metallurgy gear?
Material choices include iron powder, iron alloy powder, steel, stainless steel, copper, nickel and brass. Iron, copper and brass can also be selected for customized designs. The requested material should be identified with the gear dimensions and application.
Can a non-standard gear be made from a customer drawing or sample?
Yes. Custom non-standard gears can be developed from CAD, 3D or PDF drawings. A sample can also be used as the basis for preparing a drawing. Depending on the design, customization can cover dimensions, tooth profile, number of teeth, module, material and surface treatment.
What tolerance can a powder metallurgy gear have?
Tolerance depends on the gear design and its drawing requirements. A powder metallurgy gear can be specified with a tolerance of ±0.002 mm. Other designs use ISO 2768-m, H14, h14 or ±IT14/2. Mark the required tolerance on the drawing so it is tied to the specific part.
Which surface and heat treatments are available?
Surface treatment choices include blackening, Dacromet plating, polishing, sand blasting and electroplating. Heat treatment choices include ordinary quenching, carburizing, nitriding and high-frequency quenching. Other configurations include oil impregnation, black oxide and full hardening. Select the treatment alongside the material, application and operating conditions.
What applications use powder metallurgy gears?
Powder metallurgy gears are used in transmission parts, vehicles, home appliances, sports equipment, industrial equipment, power tools, motors, bicycles and electric bicycles. Available forms include spur, helical, bevel, worm, ring, internal ring, planetary and transmission gears. For example, a buyer specifying a vehicle transmission part should send the mating gear details and operating conditions with the tooth geometry, while a power-tool buyer should identify the application and required treatment.
What should a buyer send when requesting a quotation?
Send a CAD, 3D or PDF drawing, or provide a sample when no drawing is available. Include the material, dimensions, tooth profile, number of teeth, module, tolerance, density or hardness requirement where applicable, surface treatment, heat treatment, quantity and application. Mating gear details and operating conditions also help with design review. Before requesting a quotation, assemble the drawing or sample, the required quantity and the mating gear information.
