Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
| Parameter | What to Specify |
|---|---|
| Component scope | Sun gear, planet gear, internal ring gear and related matched components as required. |
| Tooth relationship | Provide all tooth counts, pitch system and pressure angle. |
| Number of planets | Needed to check spacing and assembly conditions. |
| Carrier / interface | Pin diameter, face width, thrust/axial arrangement and bearing relationships where relevant. |
| Material / heat treatment | Per drawing and duty for each component. |
| Inspection | Define component and system-level checks required by the project. |
These are the questions to close before production.
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
Define the datum relationship among gear teeth, bore/spline/shaft and bearing seats.
Rated and peak torque, speed, reversals, shock and life influence material/process decisions.
Agree the report content before production when tooth or interface verification is critical.
Related planet gears, ring gears and component sets for projects that require system-level matching around the sun gear.
For matched planetary components, provide the complete sun/planet/ring tooth relationship and carrier information so the set can be reviewed as one stage. Individual part photos are useful only as supporting context.

Send the drawing, tooth data, mating-component information, duty and quantity. We will review the interface before quotation.
