METHOD AND APPARATUS FOR MACHINING CONCAVE-CONVEX GEAR

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for machining concave teeth of various concave-convex gears.

SOLUTION: The method for machining includes a track extraction process (S2) for extracting a relative operation track of a convex tooth pin 12b of a mating gear 12 to the concave-convex gear 15 in transmitting power between a mating gear (a stationary shaft) 12 and a concave-convex gear (an oscillating gear) 15; and a machining process (S4) for moving at least one of a disc-shaped work and a machining tool so that a relative operation trace of the machining tool to the disc-shaped work meet the relative operation trace of a convex tooth pin 12b to the concave-convex gear 15 extracted in a trace extraction process, in machining the concave-convex tooth 15b on a concave tooth forming surface of the disc-shaped work before machining of the concave tooth 15b.
