Abstract

The invention discloses a profiling cutter and a method used for inner-tooth-line gear processing. The profiling cutter comprises a cutter bar, a cutter disc and cutter teeth, wherein the cutter bar is used for clamping a milling cutter; the cutter disc is fixedly arranged on the bottom of the cutter bar; the cutter teeth are internally concave or externally convex; the cutter teeth with internalconcave shapes are used for processing the inner-tooth-line gear of a tooth profile external convex form; the cutter teeth of external convex shapes are used for processing the inner-tooth-line gear of a tooth profile internal concave form; and the cutter teeth are fixedly arranged at left and right ends of the cutter disc. The cutting edge profile shape of the profiling cutter is conjugated witha gear surface generatrix of a linear gear, and a mathematical relationship of movement track of a milling cutter in a milling process is given. The profiling cutter has relatively good adaption to the linear gear with the gear surface inside a gear body, and improves processing efficiency and processing quality of a milled gear.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a form milling cutter and a method for processing internal tooth curve gears. Background technique [0002] Wire gear is a new type of point contact meshing gear designed based on space conjugate curve meshing theory. Through the design, the wire gear can realize the transmission of any angle in the plane and any angle in space. And the number of teeth can be designed to be 1 without undercutting phenomenon, which is easy to realize miniaturization and light weight, and has broad application prospects. [0003] However, because the tooth surface characteristics of milled gears are relatively special, if the milling cutters existing in the market are used to process milled gears, on the one hand, the processing efficiency is low, and on the other hand, the surface processing quality is also poor. [0004] Today's market urgently needs to design special milling cutters fo...
