Abstract
The utility model discloses an inner half-tooth gear shaping cutter, which at least comprises a cutter handle, a disassembling portion, a cutter body and cutter teeth. The cutter teeth are evenly distributed on the cutter body, the cutter handle is a taper shank, the disassembling portion is located between the cutter handle and the cutter body, the cutter teeth are involute half teeth which are parts of involute full teeth, tooth height of the involute half teeth ranges is1/2-3/4 of the tooth height of the involute full teeth, and cutter profiles of the cutter teeth are involutes. The inner half-tooth gear shaping cutter shortens traditional process, processed gears are precise in dimension, good consistency of the gears can be guaranteed, and the gear shaping cutter is adaptable to mass production.
Description
Technical field
The utility model belongs to the cutter that machining is used, and is specifically related to a kind of interior half tooth pinion cutter.
Background technology
It is customized that the processing of interior involute half profile of tooth needs the actual parameter of the concrete part of basis to carry out, and generally adopts the line cutting, and process is long, and the size of processing is not too accurate, and uniformity is bad, is not suitable for the large-scale production of enterprise.
Summary of the invention
For solving the above-mentioned problems in the prior art, the utility model provides a kind of interior half tooth pinion cutter, can shorten traditional process, and the gear size of processing is accurate, and guarantees to be fit to the large-scale production of enterprise by the high conformity of gear.
The technical scheme that its technical problem that solves the utility model adopts is as follows: this interior half tooth pinion cutter comprises handle of a knife at least, disassembling part, cutter hub and the cutter tooth that is uniformly distributed on the cutter hub, handle of a knife be shaped as taper shank, disassembling part is positioned at the centre of handle of a knife and cutter hub, cutter tooth is involute half tooth, the flank profil of cutter tooth is an involute, the modulus of cutter tooth is 1～3.5, the number of teeth of cutter tooth is 13～25, the cutter tooth anterior angle is 5～6 degree, the cutter tooth relief angle is 6 degree, and cutter tooth thickness is 10～15mm, and the outside diameter circle of flank profil is 25.875～48.56mm, the root diameter of flank profil is 22.5～36.75mm, and the reference diameter of flank profil is 25～45.5mm.
Described involute half tooth is the part of involute full-depth tooth, and the tooth depth of involute half tooth is 1/2～3/4 of an involute full-depth tooth tooth depth.
Adopt the utility model to add work gear, can reduce the workload of line cutting, the size of workpiece is standard more, and guarantees its high conformity, is suitable for the large-scale production of enterprise.
