Prototype vs. Production Sun Gears: What Changes in the RFQ<\/h1>\n

Prototype and series sun gears should share one approved geometry, but tooling, inspection strategy and process economics can change as volume grows.<\/p>\n

Why this topic changes the sun gear decision<\/h2>\n<\/div>\n
\n

Procurement is easier when prototype versus series supply is defined in a controlled record rather than scattered through emails. Geometry, interface, process, duty, acceptance and quantity should be distinguishable.<\/p>\n

Prototype and repeat production can use different tooling or sampling strategies while keeping the same approved geometry.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Practical design and replacement implications<\/h2>\n<\/div>\n
\n
\n

State which documents are required with shipment and whether a first-article or pilot approval is needed. Add destination and Incoterm so the commercial scope is clear.<\/p>\n

For replacement sourcing, machine references support identification, but measured gear and interface data remain the production control.<\/p>\n<\/div>\n

Foire aux questions<\/h2>\n<\/div>\n
\n
\nCan one loose sun gear answer every design question?<\/summary>\n

Usually not. Mating gear data and the center interface provide important cross-checks.<\/p>\n<\/details>\n

\nShould material or tolerance be copied from a similar part?<\/summary>\n

Only when the controlled design allows it. Similar appearance is not proof of the same duty or specification.<\/p>\n<\/details>\n

\nWhat is the fastest way to get a useful quote?<\/summary>\n

Send the latest drawing or measured tooth\/interface data, mating component information, duty, acceptance needs and quantity.<\/p>\n<\/details>\n<\/div>\n<\/div>\n<\/section>\n
