Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
SUN GEAR PRODUCTS
Engranajes solares estriados
Sun gears with spline interfaces for planetary drives requiring positive torque transfer and controlled concentricity.

Technical specification / ordering data
| Parameter | What to Specify |
|---|---|
| Gear teeth | Sun-gear module/DP, pressure angle, tooth count and helix/profile data. |
| Spline | Internal or external spline per controlled drawing/standard. |
| Spline fit | Fit class, effective length and inspection/gauge requirement. |
| Datums | Runout and concentricity relationship between gear teeth, spline and faces. |
| Material / heat treatment | Per drawing and duty. |
| Inspección | Gear and spline inspection scope agreed before production. |
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 spline interfaces for planetary drives requiring positive torque transfer and controlled concentricity.
For a replacement splined sun gear, verify both the planetary mesh and the spline standard, fit and datum relationship. Photos help identify the assembly, but spline and tooth measurements control the part.
Two tooth systems must be controlled together
The external gear teeth and center spline are separate precision interfaces. Spline fit, effective length and concentricity to the gear teeth all influence assembly and load distribution.
For splined sun gears, the external gear and spline must be reviewed as two linked tooth systems. The spline fit and effective length should be confirmed together with the external gear datum before process planning.
Preserve the specified gear and spline standards when available. If the original spline is worn, use the mating shaft or hub to separate service wear from the intended fit before the part is released.
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.
