Further, the sector gear 6 is double-layer gear, and upper strata gear empty set is equipped with cage chair axle between two layers
Brute spring, makes two-wheel stagger, to eliminate running clearance during gear drive.
Operation principle of the present utility model is as follows：
1) cutting part：By cutterhead 1 and motor 15, on bottom plate 2, motor is driven by driving belt 17
Cutterhead makees uninterrupted rotation cutting；In order to improve cutting effect：Knife cutting sword is divided into cutting to left and right sword, and cutting edge presses respective sword
Bicker degree is ground, and the total cutting edge number of cutterhead must be even number, and left and right sword mutually staggers；
2) cage chair part：Cage chair is exactly the mechanism for controlling cutter around production shape wheel central shaft rotation；
It is made up of servomotor 9, cage chair bearing block 8, sector gear 6, motor gear 10 and mounting plate 5, above-mentioned component is all
It is motionless in cutting process medium-height trestle on fixed support.The rotation of servomotor drives sector by motor gear 10
Gear 6 is rotated around bearing block, and sector gear lower gear is fixed on mounting plate, and is driven with lower component and cutterhead around cage chair axle turn
It is dynamic.
Wherein sector gear 6 is double-layer gear, and upper strata gear empty set is equipped with brute spring on cage chair axle between two layers,
Two-wheel is set to stagger, to eliminate running clearance during gear drive.
Cage chair rotating speed nShakeWith workpiece gear rotating speed nToothThan for：
nShake=nTooth× cos δ δ are gear pitch cone angle；
3) technique adjustment part：
Following three part (being set before start) is mainly adjusted according to gear parameter：
First is：The inclination angle of whole mechanism is adjusted according to pitch cone angle, unclamp on fixed mount 7 with the bolt on hole, rotate
Fixed mount, makes cage chair shaft centre line perpendicular to gear pitch cone.And adjust feed support and make cage chair shaft centre line and the gear vertex of a cone
Overlap.
Second is, adjustment cutterhead cutter tooth is tangent at tooth root midpoint, and method is：1) according to the outer cone distance of gear adjust cutterhead around
Cage chair radius of turn, the part is made up of middle supporting plate 4, line slideway, sliding block pair 14, bottom plate 2 and regulation screw mandrel 13, by turning
Start wheel 13, bottom plate 2 is moved forward or is retreated, to adjust cutter head center line with cage chair shaft centre line apart from A；2) feed is adjusted
Frame (or middle carriage) is moved down apart from B.
Computational methods are as follows：
Rfz=R/COS (ε)-b/ (2cos (ε))
B=R cos (θ)+Rfz sin(θ)-R cos(θf)-Rfz sin(θF)
In formula：
Rfz, tooth root mean cone distance mm：
R, pitch cone mean cone distance mm；
B, facewidth mm
ε, dedendum angle；θ, pitch cone angle；θfRoot angle；
A, the distance of bottom plate movement；
B, feed support (or distance of middle supporting plate movement)
3rd is, because bevel gear tooth form is intersected on the vertex of a cone, but facing cutter has certain thickness, if in cutterhead
The heart is directed at gear centre cutting, and nearly tooth trace of the tooth both sides in facewidth direction does not meet at the vertex of a cone necessarily.It must make for this in cutterhead
The heart deviates cage chair axle center, cuts left side tooth (the teeth groove left side), and cutter head center cuts right tooth toward right avertence, and cutter head center should be toward left avertence.Partially
The heart amount t=a/2, a are thickness of the cutterhead cutting edge at pitch circle.
Very accurate due to offset very little, but again, its adjustment is again auto-changing in work, is that this specially sets
Micromatic setting is counted, the micromatic setting is made up of spacing regulating block 3, electric pushrod 11, line slideway, sliding block pair 12, the component
Between mounting plate 5 and middle supporting plate 4, the gradient bottom surface of mounting plate 5 is 100：1 symmetrical notch, the spacing upper end of regulating block 3
Insertion groove is intraoral, and mobile spacing regulating block can change the gap of spacing regulating block both sides in notch in the position of middle supporting plate 4,
What is moved right is more, and gap is bigger.Electric pushrod 11, which controls to cut left and right tooth at work, to be used, and electric pushrod is released or pulled in
Measure because of the limitation of spacing regulating block 3 in groove, the gap of spacing regulating block both sides can only be eliminated, so as to reach cutterhead bias change
The purpose changed, also available step motor is replaced this device.
In the design, when bevel-gear sett is engaged, if a gear is gear blank, another gear only one of which tooth, and
The tooth is set to rotary cutter (facing cutter), makes two gears around respective central shaft with numerical control of machine tools linkage forced, and by respective
When pitch circle cone line does pure rolling, processed gear blank will be cut out a teeth groove by tool gear, and this flank profil must gradually be opened
Line, this " gear " with cutter is commonly called as producing shape wheel, and this processing method is also referred to as generating, then through indexing continues to cut next
Tooth, until cutting only.
A kind of bevel gear generating milling head described in the utility model, it is devised with the formation basic theory of the form of gear tooth
This set generating milling head, can be arranged in tooth bad production equipment, link to form bevel gear gear blank, tooth with the equipment work-piece main shaft
Shape processing integrated machine, it is to avoid little gear clamping problem and secondary clamping error, simplifies cutter, reduces cutter and use into
This, while improving operating efficiency.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent claim.
