Mating planet gears
Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.
Drawing-based sun gears for new designs and replacements requiring custom tooth geometry, interfaces, material, heat treatment or inspection.

| Parameter | What to Specify |
|---|---|
| Drawing identity | Revision-controlled drawing or approved 3D/2D definition. |
| Gear geometry | Tooth count, module/DP, pressure angle, helix/profile shift and modifications. |
| Interface | Bore, spline, shaft, keyway, thread, shoulders and datums. |
| Material / heat treatment | Grade, hardness, case/core requirement and any substitution restriction. |
| Quality | Tooth, dimensional and material/heat-treatment records required for approval. |
| Quantità | Prototype/sample, batch quantity and expected repeat demand. |
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.
Drawing-based sun gears for new designs and replacements requiring custom tooth geometry, interfaces, material, heat treatment or inspection.
For custom or legacy sun gears, submit the controlled drawing or a complete measured definition of tooth geometry and mechanical interface. Photos and markings can support identification but do not replace the drawing.

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