Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
SUN GEAR PRODUCTS
Sun Gear Shafts
Integrated gear-and-shaft components for planetary systems where gear teeth, journals, splines and retention features share one datum structure.

Technical specification / ordering data
| Parameter | What to Specify |
|---|---|
| Gear section | Module/DP, pressure angle, tooth count and tooth finish. |
| Shaft journals | Diameters, fits, lengths and surface-finish requirements. |
| Spline / key / thread | Drive and retention features per drawing. |
| Bearing seats | Datum, shoulder and runout relationships. |
| عملیات حرارتی | Controlled with attention to gear and shaft requirements. |
| Inspection | Gear runout plus shaft/spline dimensional and geometric checks as specified. |
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.
Inspection
Agree the report content before production when tooth or interface verification is critical.
Replacement and custom projects
Integrated gear-and-shaft components for planetary systems where gear teeth, journals, splines and retention features share one datum structure.
For an existing sun gear shaft, measure the complete shaft stack-up including journals, shoulders, spline or key features and their runout to the gear teeth. Photos are useful for context, not dimensional approval.
Integrated shaft geometry expands the inspection scope
Bearing seats, shoulders, threads and splines become part of the same datum chain as the sun gear teeth, especially after heat treatment.
For integrated sun gear shafts, process planning has to protect the relationship among gear teeth, bearing seats and shaft features across the full part length. Replacement measurement should therefore include the whole datum chain, not only the damaged gear section.
Material and heat-treatment requirements should be coordinated with post-treatment straightness and finishing needs. When the source is incomplete, provide torque, speed and bearing/support information to explain which surfaces are function-critical.
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.
