Description
Technical field
The present invention relates to a kind of gear working methods, and in particular to a kind of processing with bowl-shape disc milling cutter milling face gear
Method.
Background technology
Face gear drive is a kind of new gear transmission, with compact-sized, single staged transmission ratio is high, registration is big, torque
The advantage of many uniquenesses such as shunting precision height is suitable for the occasions such as space any angle commutation transmission, particularly with high-speed overload
Situation is highly suitable for aerospace field, therefore has boundless market and development prospect.
However, the flank of tooth of face gear it is not common involute or other common flank of tooth, geometry it is very complicated.It wants
The processing of realization face gear, it is necessary to have suitable processing method.The processing method of recent domestic scholar opposite gear is done
Many researchs, but at present the processing method of domestic opposite gear grasp it is inadequate, without efficient face gear Roughing and fine machining method,
Seriously affect the application and popularization of face gear.
In 102581387 A of patent of invention CN, discloses and a kind of realizing face gear milling and mill using plane disc cutter
The processing method of tooth, this method is on existing numerically-controlled machine tool, using single-sided process mode, after processing a complete flank of tooth,
Face gear carries out dividing movement, and to process next complete flank of tooth, left and right lateral tooth flank is in two different station processing.But
It is when this method is to single Gear shape process, not only to need the generating motion of cutter and workpiece, it is also necessary to along face gear tooth width direction
Repeatedly feeding, processing efficiency is extremely low, increases processing cost.
2015, BJ University of Aeronautics ＆ Astronautics professor Wang Yanzhong developed face gear grinder, using cubic boron nitride sand
Wheel has carried out the grinding of face gear, and the grinding wheel shape that this method uses is plane disc milling cutter, and Principle of Grinding and Cutting is the same as patent CN
Identical in 102581387 A, processing efficiency is relatively low.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of with bowl-shape disc milling cutter milling face
The processing method of gear, the processing method that roughing and the finishing of face gear are carried out using bowl-shape disc milling cutter not only can be with
For the mill teeth of face gear, the high-precision grinding for being heat-treated gear below is can be also used for, for the single flank of tooth of face gear, cutter
Generating motion is only needed between the gear of face, need not be fed along face gear tooth width direction, the more domestic existing plate cutter of efficiency
Processing method improves decades of times, and is effectively reduced production cost without design dedicated for the lathe of face Gear Processing.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of processing method with bowl-shape disc milling cutter milling face gear, which is characterized in that include the following steps：
1) face gear is installed on Machinetool workpiece axis, and bowl-shape disc milling cutter is installed on machine tool chief axis, and by bowl-shape dish type
Milling cutter is moved to suitable tool setting position, completes to knife；
2) in process, face gear is rotated with workpiece spindle, and bowl-shape disc milling cutter is with spindle motor around own axes high speed
Rotation, bowl-shape disc milling cutter follow machine tool rotary coiling revolution disk center to do swing campaign, meanwhile, disc milling cutter is with rotary disk edge
Two reference axis movement of the lathe in rotary disk plane carries out interpolation, makes disc milling cutter after swing campaign and interpolation, cutter
Cutting section is overlapped with virtual pinion gear.In addition, the pivot angle relationship that transforms between face gear and virtual pinion gear is quadratic function,
To obtain contact condition more preferably face gear.The axis of bowl-shape disc milling cutter is concordant with face gear tooth width midpoint always, is not necessarily to
Along face gear tooth width direction feeding can finished surface gear monodentate face machining.
3) flank of tooth is completed, face gear rotary index continues to process next flank of tooth, until completing adding for institute's geared surface
Work.
Further, the tool-tooth profile section of the bowl-shape disc milling cutter is involute, involute at its section with
The involute of virtual pinion gear fits like a glove, and has 30 ° of tilt between the center line and cutter body of involute blade place tooth
Angle.
Further, the bowl-shape disc milling cutter of the use transforms into face gear, must meet the geometry meshing relation between them,
In process, face gear around workpiece spindle rotation angle and bowl-shape disc milling cutter around virtual pinion gear center swing angle it
Between meet quadratic function relation, to obtain contact condition more preferably face gear.
Further, the bowl-shape disk cutter is needed when transforming into face gear to be put centered on the center of circle of virtual pinion gear
It is dynamic, to simulate the rotation of virtual pinion gear, follow machine tool rotary coiling revolution disk center to do swing fortune by bowl-shape disc milling cutter
It is dynamic, while disc milling cutter moves along two reference axis of the lathe in rotary disk plane with rotary disk and carries out interpolation realization.Dish type milling
Knife makees high speed rotary motion, invariablenes turning speed around its own axis.
Further, in process, it is truncated sides since bowl-shape disc milling cutter only has inside, once only transforms into a tooth
Face, when institute's geared surface of the same side of face-gear completes processing, the station of the bowl-shape disc milling cutter of reconvert, machined surface gear
Other side institute geared surface.
Further, right in order to derive disk cutter when transforming into face gear to be swung centered on the center of circle of virtual pinion gear
The inside involute blade surface of cutter carries out coordinate conversion, and inside involute blade surface is first shifted to dish type cutterhead from its coordinate system transfer
Centre coordinate system, reconvert to Virtual tool coordinate system.
Further, the processing method, can be achieved at the same time the mill teeth and high-precision gear grinding of face gear, in the case of two kinds, knife
The relative position relation of tool and workpiece is identical with movement relation, uses bowl-shape disc milling cutter when Gear Milling, when roll flute processing, general
Bowl-shape disc milling cutter changes bowl-shape disk wheel into.
The beneficial effects of the invention are as follows：
The processing method that roughing and the finishing of face gear are carried out using bowl-shape disc milling cutter, this method can not only be used
In the mill teeth of face gear, can be also used for the high-precision grinding of heat treatment gear below, for the single flank of tooth of face gear, cutter with
Generating motion is only needed between the gear of face, need not be fed along face gear tooth width direction, the more domestic existing plate cutter of efficiency
Processing method improves decades of times, and is effectively reduced production cost without design dedicated for the lathe of face Gear Processing.
