POM gear selection should start with service conditions and mating geometry, then narrow to a resin grade and process.

POM grades vary in viscosity, additives and reinforcement. The base polymer name alone does not fix wear behavior or dimensional performance.

When comparing POM grades, ask whether the application needs unfilled dimensional stability, lower friction additives, reinforcement or a particular regulatory characteristic. Each change can affect shrinkage and tooth surface behavior. If the mating gear is metal, a rough or damaged flank can overwhelm small differences between POM formulations. Inspect the mate before attributing wear solely to the plastic grade.

Inndata som skal fryses før tilbud

List the gear geometry, mating material, load, speed, temperature, chemical exposure, lubrication and production quantity.

Legg disse inndataene på den kontrollerte tegningen, spesifikasjonen eller vedlegget til tilbudsspørsmålet der det er mulig. Å holde dem unna uformelle meldingstråder gjør det enklere å håndtere leverandørsammenligninger og senere revisjoner.

Hva kan ugyldiggjøre antagelsen

Selecting a grade only because it worked in another gear can miss a different load, temperature or wear pair.

Verifiseringsstrategi

Test the chosen grade in the intended mesh if noise, life or backlash is critical.

For POM Gear Selection Guide, record the exact material grade and conditioning/environment used during validation. Material names alone are too broad for a repeat-production acceptance record.

POM Gear Selection Guide application or inspection context

Sjekkliste for innkjøp

Before requesting a price for pom gear selection guide, identify the current drawing revision, production quantity, material constraint and the feature that most strongly affects function. Ask the supplier to flag any deviation from those inputs in the quotation so technical alternatives stay visible.

Praktisk designgjennomgang for denne avgjørelsen

Material selection should connect the polymer to the function and manufacturing route. Review temperature, moisture, chemicals, stiffness, wear pair, dimensional stability and exact grade requirements. A material that performs well in isolation can still be a poor choice when the mating surface or inspection condition is different.

Registrer forutsetningene på tegningen eller i tilbudsforespørselen slik at leverandøren kan bekrefte dem før tilbudet gis. Når en verdi er ukjent, identifiser den som en åpen konstruksjonsvare i stedet for å kopiere et generisk katalognummer som kanskje ikke samsvarer med monteringen.

Verifiseringsark

  • Service temperature
  • Moisture / chemical exposure
  • Load and stiffness need
  • Wear pair / lubrication
  • Dimensional-stability priority
  • Exact grade or approved substitution limits

Bruk den første prøven til å lukke disse punktene med både dimensjonsdokumentasjon og relevant funksjonskontroll. Eventuelle aksepterte avvik bør fanges opp i den kontrollerte revisjonen før gjentatt produksjon.
