Abstract
Band fillet dovetail escape gear shaver, cutter tooth (1) is uniformly distributed in cutterhead (4) outer rim, cutter tooth (1) is fixed on tooth root (2) outer end, between adjacent two cutters tooth (1), bottom accompanies fillet dovetail escape (3), straight wall gap, fillet dovetail escape (3) both sides is up-narrow and down-wide, angle is between 5 ° to 40 °, and the straight wall in fillet dovetail escape (3) both sides and both sides, intersection, bottom surface radius of corner must be more than or equal to R0.3.The straight wall of fillet dovetail escape side, guarantees that gear shaver all possesses enough effective involute starting points in whole life cycle, the fillet of both sides, is responsible for intensity and the solution heat treatment stress concentration problem of guaranteeing cutter tooth.It is good especially that this structure is applied to effect on low module gear shaver.Need to possess enough flexible Digit Control Machine Tool to process.By the gear shaver minimum modules limit of comb groove structure, 0.8mm can be advanced to; Significantly improve cutter tooth intensity; Improve the space of escape optimal design.
Description
Technical field
The utility model relates to the construction de-sign in the cutter of Gear Processing, is especially with fillet dovetail escape gear shaver.
Background technology
Gear shaver escape has 4 kinds of structures.Domestic and Japan commonly uses hole structure; American-European conventional oat tail groove structure; Gear hobbing generate structure is commonly used in Taiwan; The intensity of hole structure is the poorest, and design optimization space is narrow.Oat tail groove structure design optimization space is large, but in the corner of dovetail without fillet, heat treatment stress easily occurs and concentrates, so cutter tooth intensity is restricted.Gear hobbing generate structure needs the nonstandard hobboing cutter of extra making, and the cycle is long and cost is high, and practical value is also little.
Utility model content
The purpose of this utility model is to provide a kind of band fillet dovetail escape gear shaver, by the gear shaver minimum modules limit of comb groove structure, can be advanced to 0.8mm; Significantly improve cutter tooth intensity; Improve the space of escape optimal design.
The purpose of this utility model will be realized by following technical measures: comprise cutter tooth, tooth root, fillet dovetail escape and cutterhead; Cutter tooth is uniformly distributed in cutterhead outer rim, cutter tooth is fixed on tooth root outer end, between adjacent two cutters tooth, bottom accompanies fillet dovetail escape, straight wall gap, fillet dovetail escape both sides is up-narrow and down-wide, angle is between 5 ° to 40 °, and the straight wall in fillet dovetail escape both sides and both sides, intersection, bottom surface radius of corner must be more than or equal to R0.3.
Especially, cutter tooth cross section assumes diamond in shape, and there is square platform on cutter tooth top.
Especially, tooth root cross section is isosceles triangle, and tooth root outer end is along being parallel to cutterhead axis, and one group of cutter tooth is evenly distributed on tooth root outer end along upper.
Advantage of the present utility model and effect: cutter tooth intensity is high, design is flexible large, and structure is unique, not easily collapses tooth, and chip space is large, and optimal design space is large.The straight wall of fillet dovetail escape side, is responsible for guaranteeing that gear shaver all possesses enough effective involute starting points in whole life cycle.The fillet of fillet dovetail escape both sides, is responsible for intensity and the solution heat treatment stress concentration problem of guaranteeing cutter tooth.It is good especially that this structure is applied to effect on low module gear shaver.Need to possess enough flexible Digit Control Machine Tool to process.Overcoming the drawback of traditional oat tail groove structure, inherit again the advantage that design optimization space is large, is relief groove structure the most advanced at present.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is cross-sectional structure schematic diagram in the utility model embodiment 1.
Reference numeral comprises: cutter tooth 1, tooth root 2, fillet dovetail escape 3, cutterhead 4.
Detailed description of the invention
The utility model principle is, the straight wall of fillet dovetail escape side, is responsible for guaranteeing that gear shaver all possesses enough effective involute starting points in whole life cycle.The fillet of fillet dovetail escape both sides, is responsible for intensity and the solution heat treatment stress concentration problem of guaranteeing cutter tooth.
The utility model comprises: cutter tooth 1, tooth root 2, fillet dovetail escape 3 and cutterhead 4.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, cutter tooth 1 is uniformly distributed in cutterhead 4 outer rim, cutter tooth 1 is fixed on tooth root 2 outer end, between adjacent two cutters tooth 1, bottom accompanies fillet dovetail escape 3, straight wall gap, fillet dovetail escape 3 both sides is up-narrow and down-wide, angle is between 5 ° to 40 °, and the straight wall in fillet dovetail escape 3 both sides and both sides, intersection, bottom surface radius of corner must be more than or equal to R0.3.
In aforementioned, cutter tooth 1 cross section assumes diamond in shape, and there is square platform on cutter tooth 1 top.
In aforementioned, tooth root 2 cross section is isosceles triangle, and tooth root 2 outer end is along being parallel to cutterhead 4 axis, and one group of cutter tooth 1 is evenly distributed on tooth root 2 outer end along upper.
In aforementioned, fillet dovetail escape 3 realizes processing with the Digit Control Machine Tool possessing enough processing flexibilities.
In aforementioned, the little gear shaver to 1.1 of cutter tooth 1 pair of modulus can be implemented to comb groove, the fillet dovetail escape 3 of optimal design, compare with milling dovetail groove with traditional punching, flexibility is higher, and cutter tooth intensity is higher, and that significantly can reduce more close-toothed gear shaver collapses tooth probability.
In the present embodiment, the modulus of comb groove radial gear shaving cutter can accomplish 0.8mm, and external existing level is 1mm, domestic existing level is 1.25mm, tooling cost is controlled, and roll flute pitch time controls in 4 hours, and comb groove pitch time controls in 8 hours; Processed gear teeth face roughness reaches Ra0.8, and Shaving Process efficiency is high, raises the efficiency more than 3 times, pitch time controlled within 30 seconds than conventional axial shaving technique.
In the utility model, the design of comb groove is based on shaving surface simulating, fillet dovetail escape 3 adopts Rouno Cormer Pregrinding Wheel dovetail groove, obtain cutter tooth intensity to greatest extent, than tradition punching and common dovetail groove cutter tooth stronger, resist and collapse tooth performance and be enhanced about more than once, take into full account to roll and shave collocation, effectively prevent that shaving step is two nibbles the problems such as interference, even can design most suitable hobboing cutter and razor is arranged in pairs or groups in direction.
During utility model works, can be used for the low module band fillet dovetail escape-comb groove structure radial gear shaving cutter of automobile gearbox gear.
