Technical specification / ordering data

Parameter	What to Specify
Product form	External sun gear; spur or helical as defined by the planetary design.
Pitch system	Module or DP per drawing.
Pressure angle	Per mating planet gear / drawing.
Tooth count	Defined by the planetary ratio and center-distance geometry.
Bore / interface	Plain bore, keyway, spline or other controlled interface.
Material / heat treatment	Per drawing and duty requirement.
Tooth finish	Hobbed/shaped/ground as required by the drawing.
Inspection	Tooth thickness/span/over-pin, runout/profile/lead or other agreed characteristics.

Selection points

These are the questions to close before production.

Mating planet gears

Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.

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

External sun gears for planetary transmissions, quoted from the tooth system, mating gear geometry and bore/interface drawing.

For replacement standard sun gears, confirm the tooth system and mating planet/ring geometry before using outside diameter as a selection reference. Photos help identify the layout, but measured tooth data control the part.
