The specific embodiment
The special-purpose processing method of the present invention for designing specially at small mode number spiral bevel gear and hypoid gear.
Below it is described in detail:
The present invention is a kind of high efficiency processing method, is used for the production gear ratio more than or equal to 3, and the bull wheel pitch cone angle is more than or equal to 70 ° small mode number spiral bevel gear, and it is different from the half rolling cut processing method that existing big-and-middle mode number spiral bevel gear is produced in enormous quantities.
The present invention adopts large and small wheel of four-axle linked CNC small mode number spiral bevel gear mill teeth machined of the good rigidly of domestic production.
Below the present invention is described in detail:
The processing of bull wheel: bull wheel of the present invention adopts two-sided method, i.e. alternate blade cutter plunge method processing substitutes original generation.The two-sided cutting of alternate blade cutter, the fixing no any rotation of bull wheel during cutting, bull wheel substitutes involute profile by straight wide profile of tooth, and teeth groove, the tooth depth of bull wheel change, and see Fig. 2.
The homalographic cutting is adopted in the incision feeding, S1 is every cutter group amount of feeding (each cutter is one group by inside and outside each cutter), be that each cutter group area of cut equates, approach does not wait, the incision feed speed is successively decreased, thick, the fine finishining of bull wheel is finished in the once mounting cutting like this, and the Tool in Cutting load is uniform and stable, has improved the life-span of cutter.
The area of cut is calculated, i.e. relatively seeing of constant speed cut and homalographic cutting is shown in Figure 1.
The processing of steamboat: because bull wheel adopts straight wide profile of tooth, Fig. 2 is that two flank profils of the alternative involute profile of the straight wide profile of tooth of bull wheel compare schematic diagram, and the outside is straight wide profile of tooth, and the inside is an involute profile, and steamboat can't mesh with bull wheel without correction.The correction of steamboat in the time of can calculating the said gear engagement by bevel gear back cone principle cuts (as shown in Figure 3) man-hour adding.By the data that calculate, the mill teeth machine carries out the correction of profile of tooth, tooth trace, tooth depth to steamboat, just can mesh with bull wheel, reaches contact zone preferably.
The processing method of steamboat of the present invention is different from half rolling cut single face cutterhead essence of big or middle mode number spiral bevel gear and cuts.But the employing alternate blade cutter, once mounting, two-way generation processing is when cutting, with rolling than correction.
Add man-hour, steamboat is thick, fine finishining is carried out simultaneously, and thick, face of fine finishining carry out roughing to another side simultaneously, promptly carries out the thick smart rolling cut processing of a flank of tooth earlier, finishes the rough lumber processing of another side simultaneously.Above-mentioned rolling cut processing one finishes, workpiece stands fast, promptly carry out cutter spacing, roll than correction, oppositely another side is carried out the fine finishining of single face rolling cut, behind the two-way rolling cut calibration (branch tooth), carry out the processing of another teeth groove behind the calibration (branch tooth), repeat above-mentioned two-way rolling cut, standing fast machines until whole teeth groove.The two-way rolling cut of steamboat can be by the different hands of spiral, add man-hour rolling cut direction and determine to revise 1) direction (concave surface of steamboat and convex surface profile), implement by programming then.(see figure 5).
The present invention adopts two-way rolling cut, carries out the incision feeding of Z axle in process simultaneously, corrected tooth groove depth (Fig. 4), and bull wheel is processed by plunge method, bull wheel teeth groove, the tooth depth (see figure 4) that changes.The bull wheel tooth root is not on root awl line.Bull wheel adds man-hour, simultaneously steamboat teeth groove, tooth root is revised, and is realized by the Z axle.The incision of Z axle is by different rolling cut directions the steamboat tooth depth to be revised (see figure 5)
Steamboat adopts two-way generation, has promptly improved stock-removing efficiency and can realize above-mentioned correction again, has satisfied the high efficiency and the high-quality requirement of half rolling cut processing method.
Adopt half rolling cut processing method processing small mode number spiral bevel gear of the present invention and hypoid gear and tool section type hard alloy cutter to use, existing working (machining) efficiency is significantly improved, save artificial and the energy, have splendid economic benefit simultaneously.
The present invention is applied to the production in enormous quantities of little modulus hypoid gear equally.
Should be noted that at last; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although the present invention has been done to explain with reference to preferred embodiment; those skilled in the art are to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical solution of the present invention.
