Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.

Technical specification / ordering data
| Parametro | Cosa specificare |
|---|---|
| Product form | External sun gear; spur or helical as defined by the planetary design. |
| sistema di lancio | Module or DP per drawing. |
| Angolo di pressione | Per mating planet gear / drawing. |
| Tooth count | Defined by the planetary ratio and center-distance geometry. |
| Bore / interface | Plain bore, keyway, spline or other controlled interface. |
| Material / heat treatment | Per drawing and duty requirement. |
| Finitura dentellata | Hobbed/shaped/ground as required by the drawing. |
| Ispezione | Tooth thickness/span/over-pin, runout/profile/lead or other agreed characteristics. |
Selection points
These are the questions to close before production.
Concentricity & runout
Define the datum relationship among gear teeth, bore/spline/shaft and bearing seats.
Dovere
Rated and peak torque, speed, reversals, shock and life influence material/process decisions.
Ispezione
Agree the report content before production when tooth or interface verification is critical.
Replacement and custom projects
External sun gears for planetary transmissions, quoted from the tooth system, mating gear geometry and bore/interface drawing.
For replacement standard sun gears, confirm the tooth system and mating planet/ring geometry before using outside diameter as a selection reference. Photos help identify the layout, but measured tooth data control the part.
Standard sun gear selection beyond the basic dimensions
Use the complete planetary mesh to validate the part. Outside diameter, tooth count and face width are useful checks but do not replace pitch system, pressure angle, profile shift and mating-gear data.
For standard discrete sun gears, freeze the mesh geometry and the locating bore or spline before selecting the tooth-cutting and heat-treatment route. Replacement work should compare the existing planets and ring so worn mating geometry is not treated as a new design target.
Where the source drawing already controls material, heat treatment or tooth accuracy, keep those requirements unchanged. If the drawing is incomplete, add duty data only to close the missing manufacturing decisions.
Before approving production
Mesh confirmation
Verify tooth system and mating planetary geometry.
Interface confirmation
Verify bore/spline/shaft fits, datums and retention.
Process confirmation
Verify material, heat treatment, finishing and coating requirements.
Acceptance confirmation
Verify tooth, runout, dimensional and documentation requirements.
