This invention belongs to mechanical range gear transmission class.

At present, its axle can not be swung during transmission such as cylindrical gears and cone gear, but but the technology of spherical gear series gearing device and transmission device axle plane rocking when having realized gear transmission, it of many uses, wherein suitable to the vehicle front driver part, the universal drive festival that its performance comparison is used at present, the angle of oscillation limit can be bigger, and rubbing when the high rotating speed of wide-angle does not increase; Patent application document CN1066717.A once disclosed above-mentioned gearing device and transmission device, narrated spherical gear and auxiliary spare part characteristics with and gearing device and transmission structures, but exist defective be disclose insufficient, word is lack of standardization, and structural behaviour is not good, for example, its gear hub design is wide, causes its maximum pendulum angle not reach alleged angle; Two its end thrust designs are too poor; The 3rd, the bearing support design is unreasonable, causes performance bad, also has other shortcomings, and the spherical gear design and production method is not enough in addition sets up.

The objective of the invention is to improve above-mentioned spherical gear and serial gearing device and transmission device, make it at axle pivot angle degree, stress performance, intensity life-span or the like aspect is better, and it is superior complete that manufacture method reaches, and make document presentation more abundant.

The following content that the present invention narrated can achieve the above object, the solution of its structure is to be made of the main part spherical gear that has improved and auxiliary spare part and part commonly used assembling, the spherical gear that has improved also divides ball, ball, olive body three kinds, the auxiliary spare part that has improved has various hemi-spherical ended shape insert hubs, pull bar, nibbles the face isogonism gear ring section such as (or arc length), goes up press table or the like, be exclusively used in the unique components of certain gearing device or transmission device in addition, as the key shaft extension contract bearing, draw frame or the like; Every kind of gearing device or transmission device all reasonably increase and decrease some component, concrete solution at first is that following main parts size is made improvements, instruct solution with the theory of engagement, the otherwise address scheme also comprises the spherical gear design and production method, divides three classes to be described in detail below:

1, the improvement of main parts size.

The structure of ball gear is based on ball, the two poles of the earth have axis hole to run through, it is axial standard pitch circle and parallel to i.e. standard pitch circle radially that sphere is used as through alignment, the middle part is that the parallel zero degree is a great circle, profile of tooth is the axial bars tooth, tooth profile parameter is identical with straight toothed spur gear basically, but modulus by great circle to the both sides roundlet by subtracting, be the COSa latitude by subtracting coefficient.Improved measure is that its axis hole is made splined hole (perhaps axis hole enlarges and uses flat key), and the axis hole two ends are expanded into cylindrical or the frustoconic shape cavity, are used for placing thrust ball bearing, about 50 ° engagements of latitude less than the little round bur one vertical pin-and-hole that connects axis hole.

The ball gear once claimed all spherical gears, the basis be one the circle solid circle, its encircle inner hypothesis can in be cut into one the circle ball; Can have can acyclic internal diameter, axis hole runs through from the ring center, toroidal surface is calibration in length and breadth, profile of tooth is the axial bars tooth, tooth profile parameter is identical with straight toothed spur gear basically, but modulus by great circle radially to the both sides roundlet by subtracting, wherein encircle internal diameter null its be COS (a ÷ 2) by subtracting coefficient, its a is ring cross section central angle.Improved measure is that axis hole is made splined hole (perhaps axis hole enlarges and the use flat key), wherein encircles the null ball gear of internal diameter, and the axis hole two ends are expanded into cylindrical or the frustoconic shape cavity, vertically run through the cylinder pin hole of axis hole at the inter-tooth slots mid point one of great circle.

Olive body gear once claimed the olive generating gear, the basis is the olive body, be made generally in the gear shaft form, tailor-made radial dimension standard pitch circle of olive face and axial calibration arc, axial graduated arc radius is exactly an olive body scope greater than great circle reference radius radially in the definition, and profile of tooth is the axial bars tooth, and tooth profile parameter is identical with straight toothed spur gear basically, but modulus pursues to both sides roundlet olive point from middle great circle and subtracts, and the number of teeth is constant.Improved measure is to set up the axle collar to take on axle, is used for takeing on apical axis and holds, and the ring shoulder is decided apart from the principle of not colliding according to the bearing support of active driven tooth hub with the olive point.

The gear hub structure is between three kinds of spherical gears, and initiatively and between driven, between pendulum type and the mutual pendulum type, its shape is all variant.Wherein the gear hub from pendulum type gearing device is cabinet type, common feature is: four layers of one piece casting that steel plate three sheaf spaces three are faced the wall and meditated, middle space with dress spherical gear and isogonism or etc. arc length gear ring section, the upper and lower layers space is respectively with adorning two pull bars, second and third layer steel plate is curved perpendicular to the edge of nibbling face, follow institute to join the spherical gear graduated arc and equate, but radius is smaller, first, fourth layer of steel plate outside is the plane; Nibble the rear wall of face relatively, if the driven tooth hub is curved or trapezoidal, but the arc radius should be greater than the gear teeth tips circle radius to stay the gap, if the driving tooth hub, its rear wall can be the plane, and there is the unthreaded hole ear on the upper and lower limit of sidewall; Pin-and-hole is driveed about the centre of sphere of institute's selective gear (or center of circle) vertical line.No matter improved measure is any gear hub, the two side is all established vertical embedded removable shoulder block formula integral body and is held axle bed, during assembling with the stud mother be fastened on the ad hoc circle of sidewall scarce in; Outer field in addition pin-and-hole next door also has an aperture.

The isogonism constant speed is the gear hub of pendulum type gearing device special use mutually, improve and adopt box two layers of steel plate one sheaf space, this space is the dress spherical gear, be the plane up and down, but respectively be connected with an arbor in the centre of sphere (or cutting the ring center of circle) vertical line top and bottom with respect to the dress spherical gear, curved with respect to the rear wall of nibbling face, its arc radius can stay the gap greater than the Outside radius of spherical gear, the vertical embedded removable shoulder block formula solid housing in two side, during assembling with the stud nut be fixed on the ad hoc side of sidewall scarce in.

One of the special one-tenth of above-mentioned stud has pin-and-hole.

There is the mechanism of adjustable degree of tightness at the pull bar middle part, and degree of tightness is regulated with nut and pad between two gears, can use stud instead when length is very few, the former macropore that is inserted in axis of rolling dynamic bearing in two ends, and the minimizing aperture is used instead and is inserted in sliding bearing.

Last press table, be two block plates up and down, grow up in wide, be used for compressing active, driven tooth hub, a side that is pressed in the driving tooth hub is provided with fixed bolt hole, and opposite side then connects by the continuous part in end, is pressed in driven tooth hub position and widens formation swing berth, improved measure is to be drilled with the oil transportation hole at last press table perpendicular to the middle part of gear, and welds low one spill containment boom with iron sheet at the edge.

Isogonism or etc. the face of the nibbling gear ring section of arc length, in pairs supporting and place up and down, be fixed on gear hub central space first three-ply plate with sunk screw nut or rivet, its gear ring graduated arc radius equals the spherical gear limb radius of being joined below the vertical line and vertical the coincidence.In view of the above, a pair of arc gear ring graduated arc radius of isogonism aspect is all identical with modulus, and etc. a pair of arc gear ring of arc length, its graduated arc radius difference, but modulus is identical.Improved measure is to set up the convex annular shoulder block, and keeping off that nearly flank of tooth steel plate makes it can not stress and be shifted, and on the center line, a side is decided to be the tooth center, and opposite side is decided to be the between cog center, is beneficial to measurement like this.

The key shaft extension bearing that contracts, structure is by with the key axle of two shoulder keys and two group of eight group totally ten six balls, loading onto the both sides semicircle that has improved holds and watt closes, its semicircle holds watt has three separate spaces and every platform, the shoulder key holds and watt adds sleeve in the separate space on platform both sides has, and fixes with the bolt and nut sunk screw, hold watt and sleeve between have tenon to close structure, the ring in the hole of bolt that middle part, sleeve outside is useful is protruding; The stroke of key axle is 1.2 times to 1.5 times of ball stroke.

2, the theory of engagement

The inventor manufactures experimently out the model of several models in order to quote as proof, and precision reaches 1MM, and it is happy to rotate swing, proves to meet the nature physics law, and measures a pivot angle and can reach 45 ° to 50 °.

According to solid geometry and gear predicate and Figure 15, be described below:

A, spherical gear structural principle

According to the solid geometry feature of ball, the centre of sphere equates everywhere that with spherical distance so strain the centre of sphere of two balls, its sphere (being equivalent to standard pitch circle) is tangent so everywhere, and therefore, the standard pitch circle of spherical gear is also tangent when swing, in view of the above feature.

Subtract because the modulus of spherical gear pursues by coefficient to the both sides roundlet from the middle part great circle, the number of teeth is constant.Meet the d=mz rule, its modulus is as follows by subtracting coefficient:

If modulus is the first letter of Yr＜reduce by subtracting coefficient〉to establish a be any latitude (the great circle place is zero), according to characteristics: common The ball gear Yr=cosa ring internal diameter ball gear Yr=cos (a ÷ 2) that equals zero has ring internal diameter ball gear, and is then as follows:

In the following formula, the latitude negative sign in the parallel to an axis line in the two ring centers of circle, cross section, a is the cross section central angle, and the axis both sides comprise two balls that the two poles of the earth are parallel, and a also is equivalent to its latitude.

Multiply by a latitude by subtracting coefficient Yr with the modulus of middle part great circle, just obtain a latitude by the modulus that has subtracted:

M is little=and m is big * Yr

(b) contradictory factor of pivot angle.

Can collide with the driving tooth hub when driven tooth hub is put to the extreme, according to measurement, the pivot angle size is inversely proportional with width, the diameter of axle and the bearing outside diameter three of gear hub, in order to make the pivot angle maximum, the diameter of axle can not be too big, and bearing should be selected middle thin for use, but consider rotating speed and mechanical strength, said two devices becomes can not be too little, therefore, reasonable approach be with spherical gear engagement less than roundlet clip, and set up axis hole end cavity to place bearing, the width of gear hub is subtracted, favourable increase pivot angle greatly.With ball gear and ball gear is example, clipping axis hole end portion roundlet establishes on the cavity basis, gear great circle d is 50,100,120,160200mm, relatively an axle d be 10,17,20,25,30mm, use bearing to be respectively 200,203,204,205,206 code names relatively, according to surveying and determination, the gearing device that is assembled into can both obtain ± about 45 ° maximum pendulum angle.Another kind of way rationally is that a side adopts narrow gear hub opposite side to adopt wideer hub also can obtain big pivot angle, reason is to handle so not positive the colliding of bearing support that makes them, and for example olive body gear hub and aftermentioned are equipped with the contract ball gear that internal diameter in the ring is arranged of bearing of key shaft extension.

(c) gearing device structural principle.

From pendulum, the meaning that to be active force make it to swing in driven tooth hub and driven shaft.

The effect of gear hub is supporting axle and spherical gear, cooperates pull bar and bearing pin indirectly two spherical gears tensions simultaneously, and its pin shaft hole is at the centre of sphere (or olive arc center of circle of olive body gear) vertical line upper-lower position, reaches to make sphere (standard pitch circle) tangent all the time.

Pull bar connects initiatively, the bearing pin of driven tooth hub, and it connects distance is active, driven gear bulb (or olive arc) radius sum.

The effect of isogonism (or etc. arc length) gear ring section be make initiatively, the tooth point of the identical modulus of driven gear accurately is meshed.

The effect of last press table provides to plane stress of gear hub and keeps this plane, and gives driven tooth hub sliding pendulum the moving berth (gap, the 1-2mm left and right sides is arranged) that provides between the two.

The contract effect of bearing of key shaft extension is that friction reduced when shaft extension was contracted.

Extend from the gear hub both sides though plot transmission shaft in the accompanying drawing, actual product should cut out a side shaft of gear hub and stay opposite side, and driving shaft can not coexist with driven shaft and cut on one side, as shown in Figure 15, so just can reach maximum pendulum angle.

Transmission shaft is directly joined wheel work does not have how likely, needs external work rotating shaft and supporting point or the like to constitute transmission device, could work better, so transmission shaft is in most cases made splined shaft in its extension.

Have accumulated angle to form from the pendulum type, mesh at 22.5 ° of latitudes as active, driven ball gear, driven shaft has just been put 45 so; But the pendulum type does not but have accumulated angle to form mutually, meshes at 45 ° of latitudes as two ball gears, and axle is just put 45.

Wherein by the isogonism constant speed isosceles triangle transmission device that constitutes of pendulum type gearing device mutually, gearing device slides along slide bar during work, and diaxon forms isosceles triangle relatively, can form the isogonism engagement automatically relatively, need not isogonism gear ring section.

When transmission was swung, its shaggy tooth can form the isogonism engagement to concavo-convex ball gear isogonism constant speed automatically, need not isogonism gear ring section from the pendulum type.

Isogonism or etc. the design of arc length gear ring section the time only design with modulus and graduated circle radius, the number of teeth is not limit, and therefore can adopt any modulus, but in fact adopts less slightly being advisable of modulus (great circle) of the spherical gear that compares the gearing device of being joined.

Spherical gear is clipped the more remaining intermediate portion of roundlet in both sides and be can be used as usefulness fixing and the spherical gear transmission, for example goalpost, annulated column, olive post.

The transmission that driving wheel also can fix with cylindrical gears.

3, the design and production method of spherical gear.

The method purpose is to improve yield rate man-hour adding, the concrete following process of division:

A. designing and mapping

Ball gear and ball gear can both directly design on drawing, determine great circle standard pitch diameter, the number of teeth, great circle modulus earlier, in the process, the base profile of tooth can axially obtained by subtracting modulus by 1 to 5 latitude on the standard pitch circle, little according to Ha=m again, that Hf=1.25m is little formula fixed point, a point be linked to be line just paint profile of tooth.

Olive body gear is generally done supporting design, need by cardboard bar or iron sheet or aluminium skin with joined spherical gear standard pitch circle arc length branch do two " olive arcs ", in pairing latitude acnode punching, in addition, subtract modulus with pursuing of above-mentioned corresponding acnode and multiply by olive body great circle standard pitch diameter, draw the some roundlet calibration of olive body diameter, measure respectively by bamboo bar or batten and to make " the diameter bar " that point has shoulder, inject in the hole of " olive arc " relatively with " diameter bar ", just obtain one asked the olive body, measure the length and the olive body arc radius of olive body, just can draw the pattern of olive body gear on drawing, above-mentioned making can enlarge size and improve validity.

Wooden shot or rosin ball that concavo-convex ball gear need equate or enlarge by means of a standard pitch circle, with by the circle tangent " three-way " that reduces by half, promptly tangent two radially pitch line and tangent front axle draw 1/2nd tooth pitches of this truncated rectangular pyramids tooth to pitch line, measure data, drawing paper again.

B. steps of manufacturing blanks

With above-mentioned drawing data molding jig, small gear can be made to the top circle degree, d is that the above gearwheel of 50mm can be made to the profile of tooth degree, because needing machine tooling therefore need amplify, adopt precision die forging method or microcast process to make blank, and on mould, set up great circle convex line sign and axis salient point sign, establish the salient point sign at the between cog center of great circle line process, the blank that makes, above-mentioned protruding sign becomes recessed sign certainly.

C. measure boring

Whether blank, it is accurate to measure above-mentioned recessed sign if being polished slightly, if accurately, with its between cog concave point shallow bore hole, but its aperture must not be greater than at the bottom of the inter-tooth slots with drilling machine.

D. add anti-its displacement transposition of pawl in man-hour

Even use precision machine tool, if come clamping work pieces, the displacement transposition is arranged unavoidably, but put in fastening and location in the blank hole with the pawl of special machine tool fixture with friction, bore, boring axis hole and mill shaving shape, can not produce workpiece shift and transposition like this and cause waste product.Can stretch one to three pawl in 180 degree around.

E. groove

After the processing of profile of tooth grinding machine, delineate great circle line and axial standard pitch circle line again, above-mentioned between cog shallow bore hole makes the great circle line more obvious if any the harmless transmission performance of trace on the contrary.

Advantage of the present invention and effect are as follows:

Because gear hub and axle can produce very big end thrust when swinging jointly, thus adopt thrust ball bearing to resist this thrust, and thrust ball bearing is placed the cavity of ad hoc ball-type gear and can not increase the gear hub width.

Transmission shaft adopts splined shaft section assembling spherical gear, because does not move at thrust ball bearing effect lower gear on the square with the axis plane that is of key end and gear cavity bottom surface, adds the fastening back of straight pin again with soldering offset aperture, helps reducing axial dimension.

Ball gear and ring internal diameter adopt the structure of cutting roundlet and setting up cavity arrangement bearing less than encircling section ball gear in footpath, reduce the width of gear hub effectively, reach maximum pendulum angle.

Employing can be rolled over embedded shoulder block formula solid housing, more compact structure, and it is steady to keep out thrust, is difficult for displacement, is difficult for displacement, even the nut loosening of double-screw bolt still has than hard intensity.The side's of employing ejector pin axle or the special one-tenth of dome bearing pin have the pawl structure, make it can not rotation, protect gear hub because of wearing and tearing make the skew of centre of sphere vertical line like this, in addition change bearing pin and sliding bearing is more economical than changing gear hub.

Wherein pendulum type gearing device adopts and to meet formula gear hub and limit fraction to draw frame mutually, makes simple in structurely, and intensity improves, and mounting or dismounting and are beneficial to the raising pivot angle easily.

Though bearing is a little bit smaller with monotubular formula diameter if the key shaft extension contracts, but separate space is greatly difficult in the machine tooling tube, a cover semicircle holds a watt formula in the tube but improve to adopt, and advantage is easy to manufacture, promptly the car of the separate space that holds watt of semicircle, mill, dig, grind to process to open wide and carry out.

The advantage that face isogonism gear ring section is nibbled in employing be simple in structure, torsion is big, size is little, is preferred forms (down with).

The A2 type:

This kind of is that the face of the nibbling isogonism gear ring section 13 of Figure 16 Figure 17 is exempted, and uses bar shown in Figure 10 instead and puts gear isogonism mechanism, and or three layers of driven cabinet type ball gear hub 9 back side arc walls are windowed allow pull bar extend through.

The structure that bar is put gear isogonism mechanism is: driven tooth hub arc wall is joined the outer tooth plate of arc, last press table termination case assembling arc inner tooth plate, and the two is meshing two cylindrical gearss that connected by pull bar, as shown in figure 10, following same aftermentioned.

It is as follows that bar is put gear isogonism organization data design method.

Record known t1: t2=x1: x2=r3: r4=r2: r5=1: 3, according to rule, so:

R2=r1+x1 (surveying r1=t1)

r3＝(3x1－x1)÷(1＋3)×?1

r4＝(3x1－x1)÷(1＋3)×3

R5=(3r1+3x1 (r1 is the reference radius of ball)

If r1 is 50mm, x1 is 30mm, and substitution is above various, gets r2=80mm, r3=15mm, r4=45mm, r5=240mm.

The center of circle of r2 and r5 is respectively bearing pin.
