Count first<\/h2>\n<\/div>\n

Record the sun, planet and ring tooth counts and the number of planet gears.<\/p>\n<\/div>\n<\/section>\n

\n
\n
\n

Measure the interface<\/h2>\n<\/div>\n

Capture bore\/spline, shaft journals, shoulders, keyways, threads and retention features.<\/p>\n<\/div>\n<\/section>\n

\n
\n
\n

Do not infer tooth geometry from OD alone<\/h2>\n<\/div>\n

Outside diameter is useful, but module\/DP, pressure angle and profile shift need independent confirmation.<\/p>\n<\/div>\n<\/section>\n

\n
\n
\n

Photos help, measurements control<\/h2>\n<\/div>\n

Send photos for identification context together with measured dimensions and the mating components.<\/p>\n<\/div>\n<\/section>\n

\n
\n
\n

Use the drawing as the controlled record<\/h2>\n<\/div>\n
\n
\n

A technical guide can explain which variables matter, but the final sun gear must be approved from the actual drawing and operating requirement.<\/p>\n

If a value is missing, identify it for confirmation instead of copying a dimension or material from a different supplier or gear family.<\/p>\n<\/div>\n

RFQ checklist<\/h2>\n<\/div>\n

Send the sun gear drawing or measured tooth data, mating planet\/ring information, interface dimensions, material\/process requirements, duty, quantity and destination.<\/p>\n<\/div>\n<\/section>\n

\n

Deeper buyer guidance<\/h2>\n<\/div>\n
\n
\n

Replacement measurement should separate original geometry from wear, damage and service-created deformation.<\/p>\n

For new designs, use the complete planetary geometry and functional datums before deciding the process route. For replacement work, use photos and equipment references for context but let measured tooth and interface data control the new part.<\/p>\n<\/div>\n

Frequently asked questions<\/h2>\n<\/div>\n
\n
\nCan a visual match confirm interchangeability?<\/summary>\n

No. Similar outside dimensions can hide different pitch systems, pressure angles, profile shift or interface fits.<\/p>\n<\/details>\n

\nShould mating gear data be included?<\/summary>\n

Yes whenever available, because planetary geometry is easier to verify as a system.<\/p>\n<\/details>\n

\nWhat if a value is unknown?<\/summary>\n

Mark it as open and provide the available sample, mating component or application data rather than guessing.<\/p>\n<\/details>\n<\/div>\n<\/div>\n<\/section>\n
