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
| Parameter | What to Specify |
|---|---|
| Geometría del diente | Module/DP, pressure angle, tooth count and any profile shift. |
| Bore | Diameter, fit, keyway/spline if present and axial length. |
| Wall / hub geometry | Section thickness, shoulders and retention features. |
| Mating components | Planet gear and ring gear data. |
| Material / heat treatment | Per application and drawing. |
| Inspección | Bore-to-tooth concentricity and required tooth measurements. |
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.
Duty
Rated and peak torque, speed, reversals, shock and life influence material/process decisions.
Inspección
Agree the report content before production when tooth or interface verification is critical.
Replacement and custom projects
Sun gears with through-bores or hollow interfaces for compact coaxial planetary arrangements.
For replacement hollow sun gears, verify bore fit, bore-to-tooth concentricity and the mating planet/ring geometry together. Photos can show the arrangement, but the controlled measurements determine interchangeability.
Bore size changes the section and the process plan
A large through bore or internal spline reduces the remaining section between the center feature and tooth root, so duty, wall thickness and distortion should be reviewed together.
For hollow sun gears, freeze the external tooth system and the bore or internal spline as one section before selecting the process route. The remaining wall thickness and gear-to-bore concentricity are central to the part definition.
If material and heat treatment are already specified, preserve them. If the bore size or internal feature is being changed, include torque and duty information so the effect on section strength and distortion can be reviewed.
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.
