Custom Sun Gear RFQ Inputs That Matter
A complete custom sun gear RFQ joins the gear mesh, shaft interface, duty, quality and commercial requirements in one controlled package.
Gear geometry
Tooth count, module/DP, pressure angle, helix/profile shift, tooth modifications and inspection definition.
Mechanical interface
Bore, spline, shaft, bearing seats, shoulders, threads, keyways and retention.
Duty and quality
Torque, speed, shock, life target, material/heat treatment, finish and required records.
Commercial information
Quantity, prototype need, annual demand, destination and trade term. For custom sun gears, keep the product terminology tied to the controlled drawing so tooth geometry, interface and process requirements stay unambiguous before ordering.
Use the drawing as the controlled record
A technical guide can explain which variables matter, but the final sun gear must be approved from the actual drawing and operating requirement.
If a value is missing, identify it for confirmation instead of copying a dimension or material from a different supplier or gear family.
RFQ checklist
Send the sun gear drawing or measured tooth data, mating planet/ring information, interface dimensions, material/process requirements, duty, quantity and destination.
Deeper buyer guidance
A useful RFQ separates geometry, interface, process, duty, inspection and commercial information so open items can be clarified explicitly.
For new designs, use the complete planetary geometry and functional datums before deciding the process route. For replacement work, use photos and equipment references for context but let measured tooth and interface data control the new part.
What to control on the RFQ or drawing
| Barang | What to define |
|---|---|
| Planetary mesh | Sun, planet and ring tooth data plus planet count when known. |
| Center interface | Bore, key, spline or shaft features with functional datums. |
| Operating duty | Rated/peak torque, speed, reversals/shock, life and environment. |
| Material/process | Controlled material, heat treatment, finish and coating requirements. |
| Acceptance | Gear/runout/dimensional checks and required documentation. |
Frequently asked questions
Can a visual match confirm interchangeability?
No. Similar outside dimensions can hide different pitch systems, pressure angles, profile shift or interface fits.
Should mating gear data be included?
Yes whenever available, because planetary geometry is easier to verify as a system.
What if a value is unknown?
Mark it as open and provide the available sample, mating component or application data rather than guessing.
