hypocycloidal การใช้

The problem employs the " study of involute cycloidal, epicycloidal and hypocycloidal curves ."
The addition of geared, all-mechanical wheels for manual wheelchairs is a new development incorporating a hypocycloidal reduction gear into the wheel design.
The Thinktank museum, Birmingham, England, is the third-oldest working engine in the world, and the oldest working engine with a hypocycloidal gear.
In cycloidal gears, the addenda of the wheel teeth are convex epi-cycloidal and the dedenda of the pinion are concave hypocycloidal curves generated by the same generating circle.
