Selection points<\/h2>\n<\/div>\n

These are the questions to close before production.<\/p>\n

\n
<\/span><\/p>\n

Mating planet gears<\/h3>\n

Confirm the mating tooth count, pitch system and pressure angle rather than identifying the sun gear in isolation.<\/p>\n<\/article>\n

<\/span><\/p>\n

Concentricity & runout<\/h3>\n

Define the datum relationship among gear teeth, bore\/spline\/shaft and bearing seats.<\/p>\n<\/article>\n

<\/span><\/p>\n

Duty<\/h3>\n

Rated and peak torque, speed, reversals, shock and life influence material\/process decisions.<\/p>\n<\/article>\n

<\/span><\/p>\n

Inspection<\/h3>\n

Agree the report content before production when tooth or interface verification is critical.<\/p>\n<\/article>\n<\/div>\n<\/div>\n<\/section>\n

Replacement and custom projects<\/h2>\n<\/div>\n
\n
\n

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

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.<\/p>\n<\/div>\n
