ASSEMBLING TYPE INTERNAL HELICAL GEAR

摘要

PURPOSE: An assembling type internal helical gear is provided to assemble a plurality of gear teeth in the shape of helical gear into an inside of an internal gear, thereby resolving the complicated machining of the internal helical gear and improving the precision of the internal helical gear. CONSTITUTION: An assembling type internal helical gear includes a ring-shaped body part(110), a plurality of gear teeth(120) continuously disposed on an inner peripheral surface of the body part at rear surfaces and machined as a helical gear separately from the body part, and fixing elements(130) for fixing the gear teeth to the body part by screw-coupling upper and lower parts of the inner peripheral surface of the body part with upper and lower parts of the gear teeth.
