Lightweight Gearbox Technology, Phase I

To date, the majority of the gearboxes used on the rovers have been based on very conventional materials, process and designs. This has primarily been a result of the fast paced schedules associated with rover development. With little time for recovery, these programs are extremely risk adverse and the idea of developing new technology on the program is absolutely impractical. As there is no rover planned for the 2007 there is a longer than normal dwell between rover programs. The hope is to capitalize on this time to advance the technology used on the common gearboxes employed on the rover. This will allow new technology to be introduced into the gearbox designs. The plan for reducing the gearbox mass relies on a three pronged approach. First, design innovations above and beyond AGMA standards will be evaluated for incorporation into the basic planetary gearbox design. Second, advanced materials and processes will be evaluated for use in gears and planet bearings. And lastly, the cost implications of the advanced technology will be compiled to insure the correct balance is maintained between weight reduction and cost expense.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
