(annotate: present patent application entrusts examination department of Patent Office retrieval service place to retrieve on July 28th, 1987, does not find the file relevant with novelty; Or with the closely-related file of special topic.(examination department of attached middle school state Patent Office search report copy))
According to available data, maximum in the world at present gear grinder is the HSS-460B gear grinder of Switzerland MAAG company, and its maximum processing gear diameter is 4734mm; Maximum modulus is 36mm; The maximum gear grinder that China had is a MAAG HSS-360 gear grinder of the Sichuan factory import sixties, and it adds the work gear maximum gauge is 3600mm, and maximum modulus is 20mm.Industrial equipment develops to the maximization direction day by day at present, and large transmission gear generally adopts the hard flank of tooth in order to improve bearing capacity and to increase the service life, and is badly in need of the finish machining equipment of large-scale hardened face gear.Existing gear grinder (comprising disclosed existing patent) all adopts generating processing, and the required transmission chain length of lathe will guarantee machining accuracy, and is very high to the driving member required precision, so cost is very expensive.On the other hand, the basic design philosophy of existing gear grinder is to try hard to process the standard involute flank, but industrial practice proves, stress deformation when considering the actual gear transmission and thermal deformation and gear manufacturing and installation equal error, must tackle profile modification mutually in order to reduce dynamic loading, impact, interference and reduction rotational noise, the crushing of existing gear grinder and lathe adjustment are all very complicated and consume more man-hour.In addition, the base circle diameter (BCD) of the existing measurable maximum gear of producing of accuracy of gear measuring instrument is 1900mm(such as MAAG SP-200).
The objective of the invention is for the large gear processing that solves above-mentioned existence and the difficulty that detects and problem with machining tool and precision testing device molten be indivisible complete system of one formation, and can satisfy the requirement of various different profile modifications more easily; A kind of new technique scheme that adopts envelope method to form the large-scale gear grinding machines of flank profil is proposed for this reason.
Technical scheme of the present invention is: form the novel gear grinding machine of the flank of tooth with the planar envelope method, it is by workbench (6), lathe bed (9) radially, fan-shaped guide rail (8), cage chair (7), column (1), crossbeam (2) and be with the bistrique (4) of emery wheel (5); And indexing system and accuracy detection system form.It is characterized in that when roll flute, the workpiece gear that is installed on the workbench (6) is fixed, cage chair (7) by having bistrique (4) around one relevant with the workpiece tooth curve, the envelope movement of emery wheel (5) transverse plane is finished in the position through the swing that preferably is fixed on the pivot (27) on the fan-shaped guide rail (8); The mathematical relationship that in the envelope process, must keep simultaneously P=R ± △ R, wherein P is the length of perpendicular to emery wheel (5) transverse plane from the axis of pivot (27), and R is a constant, and △ R is a small variable.According to given tooth curve and requirement on machining accuracy thereof, calculate by discretization, can try to achieve a series of and any angle of oscillation θ
iCorresponding △ R
iLike this, in flank profil envelope process, at emery wheel (5) end face around pivot (27) with when deciding radius R and do simple gyration, additional the additional of a △ R moves radially.Replenishing motion △ R realizes by digital control system.Be contained in cage chair (7) and go up and the coaxial grating encoder of pivot (27), press cage chair angle of oscillation θ
iSize send signal, by importing the data △ R of microcomputer in advance
i, send certain umber of pulse control stepper motor (3) and rotate, thus the additional mobile △ R of control emery wheel (5)
i(referring to accompanying drawing 6).
Another characteristics of grinding method of the present invention are to make the plane of emery wheel (5) and flank profil that one section controllable contact line length be arranged, like this, from an end of tooth begin along the tooth length direction piecemeal envelope go out full-depth tooth long (actual add man-hour adjacent segment all have certain overlapping).Crossbeam during roll flute (2) is clamped on the column (1), after emery wheel (5) is through one section flank of tooth of reciprocally swinging formation several times, crossbeam unclamps from the column guide rail, make it vertically move a segment distance (less than contact line length) along the column guide rail, clamp again then, emery wheel (5) can remake the roll flute motion, has ground whole facewidth successively piecemeal.If, can realize along the axial modification of tooth length direction in the micro-gradually value that changes radius R of tooth length direction.
Adopt computer-aided design optimization method, can select pivot (27) axis with respect to the coordinate position of workpiece gear with decide the radius R value, optimal conditions is that the flank profil that envelope is gone out reaches optimum condition by required precision.The optimizer block diagram is seen accompanying drawing 2.
Through calculating, in the ordinary course of things, △ R＜1mm; Just under extreme case, promptly very big the and number of teeth of modulus seldom the time △ R just big slightly.As modulus is 40mm, and the number of teeth is 20 o'clock, △ R
MaxApproximate 2.5mm.Less △ R makes lathe numerical control device obtain simplifying, and machining accuracy also improves than being easier to.
The flank of tooth formation method of large-scale gear grinding machines mainly is to adopt generating in the world at present, generating motion is rotated by workpiece and rectilinear motion is formed, emery wheel only rotates and straight reciprocating motion, the generating motion of workpiece is to make workpiece as rolling on fixing instrument tooth bar, processes the flank of tooth by the ablation of imaginary instrument tooth bar.This quasi-mill tooth machine often brings an insurmountable problem, and workpiece is done the constant speed rotation in the generating motion, presses the involute generating principle, tooth root portion flank profil generate speed is slower, tooth top portion flank profil generate is very fast, has so just caused gear top tooth-face roughness big, and surface quality is poor.Slow and very fast at the tooth top place in tooth root place generate speed by the generating motion that constant speed is finished than driving-chain, this contradiction can't overcome.As everybody knows, in Involutes Gears Transmission, tooth top and tooth root are when being meshing with each other transmission, exist relative slip, and maximum slip velocity is when just in time occurring in the engagement of tooth top and tooth root, thereby coarse tooth top surface can cause very big friction loss along the flank profil direction, frictional work converts heat to rises frictional surface temperature, can reduce lubricating oil viscosity and cause lubrication to lose efficacy, under high temperature (moment flash temperature), high pressure, often make the flank of tooth produce scratch or scuffing failure.This can reduce transmission efficiency greatly and shorten the working gear life-span.In order to address the above problem, the invention is characterized in and adopt the Grinding Contact district, arrowband of a length controlled system to move back and forth along the flank profil direction, form continuous flank profil curved surface, can guarantee that again group velocity relatively evenly or by actual needs regulates and control flank profil any point group velocity.Contemplated lathe adopts two emery wheels two sides of grinding tooth respectively, uses this monodentate face teeth grinding method to treat with a certain discrimination the gear teeth two flank of tooth crudies and required precision.Because most travelling gears are unidirectional transmissions.That serves as main drive task only is a side of the gear teeth, therefore should propose different crudy and required precision to two lateral tooth flanks of tooth.But because in the existing gear working method, gear tool (as bipyramid facet wheel, worm abrasion wheel) all is to adopt no backlash mode to process two lateral tooth flanks of the gear teeth simultaneously, can't be treated with a certain discrimination two flanks at all.What is more, when with generating grinding simultaneously wheel tooth two flanks, because the contacting points position of emery wheel working face and the gear teeth two lateral tooth flanks grinding simultaneously often is asymmetric, thereby the size and Orientation of both sides grinding force also is different, and this unbalanced variation has greatly influenced precision of grinding teeth.Particularly for large gear, the processing gross area is very big, and as two flanks are not made any distinction between, then in fact having half finished surface long-pending is to surpass the actual needs quality requirement, and this has just run counter to economic principle.Technical scheme of the present invention has been considered this factor fully, adopts flank of tooth both sides difference method for processing, can satisfy actual requirement, has reduced labor content again, thereby can bring very large economy benefit.
In sum, compare with existing gear grinding machines, gear grinding machines of the present invention have following obvious technological merit:
1. the process principle that machine adopted is new makes lathe avoid the generating motion mechanical drive train that adopts traditional tediously long required precision very high, thereby has greatly simplified machine tool structure, is easy to make, and is convenient to the manufacturing and the assembly precision that reach higher.
2. adopted structure to be simple and easy in the advanced static pressure technology of making, main motion parts is moved under the perfect lubrication condition, and has very high kinematic accuracy, very high bearing capacity (as workbench, cage chair etc.) is also arranged, again because movement parts does not almost have friction and wear, thereby not only mechanical efficiency height but also long working life, very high precision stability is arranged, also removed frequent maintenance load from.
3. machine tool structure is not subjected to the restriction that diameter of work increases, lathe size, weight yet can not increase and increase proportionally with diameter of work, lathe real work portion size is only relevant with the module size, thereby can significantly reduce the gross weight of lathe, easy for removal and installation again, can allow lathe transport the gear erecting yard to the processing of super-huge gear and process on the spot.
4. this lathe has been realized workpiece detection on the throne, need not unload workpiece and just can detect the workpiece machining accuracy at any time, and testing result provides reliable guidance data for the accurate adjustment of lathe again, thereby has created condition for improving the Gear Processing precision.Therefore whole lathe has constituted processing and has detected supporting complete process system.
5. gear teeth face is formed as the section envelope by the emery wheel end face, contacting of emery wheel and flank profil is the Grinding Contact district, arrowband that a length can be controlled, it moves back and forth along the flank profil direction and can form continuous flank profil curved surface, the rib degree that has produced on the flank of tooth when having avoided traditional roll flute.Because group velocity can be adjusted arbitrarily, the tooth root generate speed in traditional generate processing method of having solved is slow and tooth top generate speed is fast and the contradiction that can't overcome again.
6. can control and regulate by microcomputer at an easy rate the group velocity of flank profil, so just can be under the situation that does not influence productivity ratio, reduce the roughness of flank profil tooth top surface, can avoid grinding burn and consequent grinding crack again, reduce surperficial residual tension, thereby guaranteed the surface integrity of the flank of tooth, helped improving the working life and the reliability of gear.
7. can satisfy the correction of the flank shape requirement of the gear teeth with comparalive ease, this can import corresponding correction of the flank shape parameter by microcomputer and realize, need not make model specially or pattern removes to repair the emery wheel working face, therefore grinding correction of the flank shape flank profil is had good flexibility.
8. new gear grinding machines can be processed respectively gear teeth two sides, can improve the precision of groundwork face, also can suitably reduce the precision of the underwork flank of tooth simultaneously, thus can treat with a certain discrimination, thus can improve roll flute productivity ratio, obtain favorable economic benefit.

1. workbench (6), it be the supporting and the positioning element of workpiece gear be again the rotary table of accuracy detection.
Workbench of the present invention is characterised in that in the roll flute process it is fixed (being clamped by clamp mechanism).This particularly divides the tooth precision most important for the machining accuracy that improves gear.Behind the intact tooth of every mill, do the calibration gyration.The revolution of workbench is to drive by DC servo motor by planet pinion.For rotating accuracy that improves workbench and the rotary resistance that reduces it, particularly when low speed or fine motion, guarantee not occur creeping phenomenon, to improve its positioning accuracy, the main shaft of workbench adopts hydrostatic bearing, and end surface supporting spare adopts the static pressure round guide.
2. bistrique (4) is installed on the crossbeam (2), and bistrique is left and right respectively one, respectively two flank of tooth of the grinding gear teeth.Emery wheel (5) is fixedly mounted on the grinding spindle, and main shaft supporting is on two hydrostatic bearings.Stepper motor (3) makes main shaft make minute movement △ R(vertically referring to accompanying drawing 6 by precision ball screw pair of nut (10) and cotter mechanism (11)), minimum mobile step pitch is 0.5 μ m.
During roll flute, at first bistrique is moved horizontally on crossbeam, makes the oscillation center of emery wheel end face and cage chair (7) equal the monolateral allowance of flank profil for R+S(S apart from (with the distance of pivot (27))), then bistrique is clamped on the crossbeam, can carry out roll flute.
Accompanying drawing 6 is the grinding wheel head structure profile.
(1), transmission of power: drive main shaft and emery wheel (5) rotation generation cutting movement by belt transmission by motor.
(2), axially replenish motion: make emery wheel (5) make axially micro-mobile △ R by stepper motor (3) → ball-screw (10) → cotter mechanism (11) → thrust bearing (13) → main shaft (12).
The emery wheel (5) of the present invention's conception adopts fabricated structure (referring to accompanying drawing 8,9).
At present general gear grinding machines emery wheel all adopts cantilever arrangement, mainly be for the loading and unloading that make emery wheel and easy to adjust, but the poor rigidity of emery wheel at this moment is unfavorable to improving precision of grinding teeth, grinding spindle adopts double supporting structure in lathe of the present invention, and this has just improved main axis stiffness greatly.Emery wheel (5) is combined by metallic matrix (18) and abrading block (17), is convenient to change abrading block.Also can slot on the abrading block working face, carry out interrupted grinding, make grinding fluid be easy to enter grinding area, to reduce the grinding area temperature.This emery wheel adopts cubic boron nitride abrasive materials, and the characteristics of this emery wheel are the hardness of the abrasive grain height, and not easy to wear, grinding force is little, and grinding temperature is low, and the surface of the work integrality is good after the grinding.
3. crossbeam (2) is the holding components of bistrique (4), and bistrique (4) can move horizontally (fast moving, motor-driven or manual fine-tuning) thereon and show by precise grating footage word to regulate size R().Crossbeam itself is installed on the column (1), and can be for vertical movement along the column guide rail.
4. column (1) is the supporter of crossbeam (2), and it is fixed on the cage chair (7), and the cage chair band it can go up swing at the fan-shaped guide rail (8) of cage chair.
5. cage chair (7) connects firmly together with column (1), and it is the supporting member of column (1), is again the mechanism's main part that forms envelope movement.Cage chair (7) can be around centrally-pivoted axle (27) swing of following fan-shaped guide rail (8).The bearing of cage chair at the pivot place also adopts hydrostatic bearing to improve rotating accuracy.Cage chair (7) can realize that with hydraulic oil cylinder driving the even variation (make the tooth top place slower, the tooth root place is very fast) of emery wheel feed motion, motion steadily also can realize infinitely variable speeds.When swinging to end positions, cage chair have buffer gear and adjustable limiting device (as block) to limit the angle of oscillation of cage chair.
Hydrostatic support is also adopted in the swing of cage chair (7) on fan-shaped guide rail, and the oil pocket distribution situation of cage chair bottom surface as shown in Figure 10.The identical oil pocket of letter matches among the figure, as A-A, and a-a ... Deng, each charge oil pressure to oil pocket connects with an adjustable guiding valve flow controller.Capitalization English letter oil pocket such as A-A ... Deng, the deflection that is used to adjust cage chair and produces around Y-axis because of the size variation of the variation of the working portion position of centre of gravity of forming by column, crossbeam, bistrique etc. and grinding force.Small letter English alphabet oil pocket such as a-a ... Deng then be used to adjust whole work partly when the roll flute around the deflection of X-axis.Its purpose is to make cage chair to remain on very when work and approaches to swing in the desirable level face.
Accompanying drawing 5 expression lathe top plan views, at this moment cage chair is in the position (during the mill pinion) near the workbench center.Cage chair can be swung about 45 altogether.
6. fan-shaped guide rail (8) is the supporting member of cage chair (7) and superstructure thereof, has arc corresponding with the oil pocket of circular (coaxial with oscillation pivot (27)) flat guide and cage chair bottom surface above it.There is guide pass to be bearing in radially on the lathe bed (9) below it.
7. radially lathe bed (9) is the supporting member of fan-shaped guide rail (8).Fan-shaped guide rail (8) the radially guide rail of lathe bed moves as radial level, with the axle center of adjusting oscillation pivot (27) distance with respect to the workpiece gear axle center, with size that adapts to workpiece gear and the optimum position of obtaining cage chair (7) swing.In order to grind less gear, radially lathe bed (9) extend to workbench below.
8. indexing system (referring to accompanying drawing 11,12) mainly is made up of error auto compensatng steel ball dish (patent No. CN85101981) calibration instrument (19) (having photoelectric collimator or photoelectricity alignment device) and the plane mirror (20) that is fixed on the workpiece gear.The calibration instrument be contained in bridge type beam (21) below.Bridge type beam can be made the Height Adjustment of horizontal level along two cylinders (22), to adapt to the workpiece of different size.Must be pointed out that the small eccentric error of the axis of calibration instrument and workpiece gear can not influence indexing accuracy and gear teeth circular pitch error and accumulative pitch error at all.
9. accuracy detection system (referring to accompanying drawing 13): owing to still there is not gear detector greater than the 2000mm diameter at present, the height of large gear is disembarked simultaneously, and to detect be worthless.This be because: (1) large gear cost height, do not allow to scrap, detect to guarantee machining accuracy so must be implemented in the position.(2) gear leaves lathe and carries out accuracy detection if find need to reprocess when defective, and at this moment workpiece reinstalls on the lathe, and its positioning accuracy is difficult to guarantee.So this machine adopted workpiece detection mode on the throne has realized the unification of machine instrument.The A district is the processing district in the accompanying drawing 13, and the B district is a detection zone.Detection system mainly is made up of circular pitch somascope (23), profile of tooth somascope (24) and teeth directional somascope (25).Platen is exactly the workbench of detection system.Three detectors are supported with the support (26) that can do to move radially and are fixed to adapt to the gear measurement of different-diameter.
When detecting circular pitch error, workpiece is done slowly to rotate continuously, is with flexibly mounted pair of contact gauge head reciprocating, is in adjacent two flanks on the same radial location by the tooth measurement.Measurement data can print the error amount by tooth automatically after MICROCOMPUTER PROCESSING, simultaneously printablely after MICROCOMPUTER PROCESSING go out circular pitch worst error value and accumulative pitch error value.The profile of tooth somascope is characterised in that and adopts the present invention to process the same operation principle of flank profil, detects data and can print automatically or show with figure equally by microprocessor.Because workpiece is a straight-tooth gear, so the teeth directional detector more easily reaches higher certainty of measurement.
Also can settle double-flank gear rolling tester or single-flank gear rolling tester and flank of tooth contact (area) pattern somascope at detection zone as required.
Operation principle according to the present invention replaces emery wheel can become large gear mill teeth machine the plane milling cutterhead, adds that with the slotting tool of rectilinear edge suitable relieving mechanism also can become shaping machine.
During operation principle of the present invention can be applicable to too, the machining tool of fine module gear.
