Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
As a example by worm wheel grinding standard involute helical gear, a kind of numerical control worm wheel grinding method of cycloid gear, comprise the steps:
As it is shown in figure 1, the parameter in figure is respectively as follows:
RZFor pinwheel radius；
K1Curtate ratio for cycloid；
ZbFor the pinwheel number of teeth；
ZaFor the cycloid gear number of teeth；
ψ is (being formed centrally method without the bag) r corner relative to R；
x0、y0For cycloid gear tooth profile equation；
X, y are cycloidal equidistance curve form equation.
By cycloid forming process, use geometrical relationship can show that the tooth profile equation of cycloid gear is as follows:
If the radius of pin gear sleeve is rZ, the common normal of the flank profil arbitrfary point of cycloid and the angle of X-axis are γ, then the equation of cycloid gear flank profil equal space line is as follows:
X=xo+rZcosγ
Y=yo-rZsinγ
In formula:
The three-dimensional profile of cycloid worm abrasion wheel, the i.e. helical tooth flank of cycloid worm abrasion wheel.Its normal tooth profile or axial tooth profile is used to analyze its meshing characteristic, therefore, it is necessary to first solve its helical tooth flank equation.Setting up the spatial conjugate relation of cycloid gear and worm abrasion wheel, Fig. 2 is the position of engagement relation of cycloid gear and worm abrasion wheel, and Fig. 3 is cycloid gear and worm abrasion wheel engaged transmission relation.According to figure, odzdIt is the rotation of worm abrasion wheel, ogz0Being the rotation of workpiece, the lead angle on worm abrasion wheel pitch cylinder is λ.Worm abrasion wheel with the gearratio of cycloid gear is:
In formula: zgThe workpiece number of teeth (i.e. the number of teeth of cycloid gear),
The head number of z worm abrasion wheel,
The angle of workpiece revolution,
Workpiece turns overAfter, the angle that worm abrasion wheel is turned over.
Pitch radius R of worm abrasion wheeldjAnd being calculated as follows of helical pitch T:
Wherein, RgjBeing workpiece pitch radius, this parameter is determined by designer.
Worm abrasion wheel axis with the minimum distance of axis of workpiece is:
K=Rgj+Rdj
The establishment of coordinate system relation of cycloid gear and worm abrasion wheel is as follows:

Od(XdYdZd) it is the moving coordinate system connected firmly with worm abrasion wheel.
Od(Xd0Yd0Zd0) it is the reference frame determining worm abrasion wheel locus, it is fixed on space, OdZdAxle and OdZd0Axle random time all overlaps.
Workpiece to be machined is cycloid gear, and its profile of tooth is the equal space line of curtate epicycloid.Owing to cycloid gear is straight-tooth, therefore pitch plane is vertical with the rotation of workpiece, i.e. participates in the point of engagement, for the point on contrate tooth profile.Now set up workpiece (cycloid gear) tooth surface equation M (X, Y, Z):
X=X (ψ)
Y=Y (ψ)
Z=h
This formula is cycloid tooth surface equation, and owing to it is spur gear, h is constant, during h=0, is the end face of cycloid gear.
According to cycloid gear and the installation site of worm abrasion wheel and gear motion relation, the contact point M (X, Y, Z) expression formula in cutter connects firmly coordinate system, i.e. Contact line equations can be drawn by coordinate transform.Concrete calculating process is as follows:
Arrange above various:
In formula:
Obtain Contact line equations, when contact line is around OdZdAxle with angular speed θ rotate, and ensure helical pitch be T for the helical movement time (as shown in Figure 4), its movement locus is the helicoid of worm abrasion wheel, and expression formula is as follows:
I.e.
Work as XdmWhen=0, obtaining the axial blade form equation of worm abrasion wheel, it is expressed as follows in tool coordinate system:
Ydz=Xdsinθ+Ydcosθ
Worm abrasion wheel is really the normal direction flank of tooth internal messing at worm abrasion wheel with cycloid gear, when ensureing strict screw, angle between normal section and shaft section is λ (as shown in Figure 5), therefore normal direction blade form equation is expressed as follows in tool coordinate system:
Xdf=Xdcos(θ-θ1)-Ydsin(θ-θ1)
Ydf=Xdsin(θ-θ1)+Ydcos(θ-θ1)
Wherein,
Owing to the form equation of above normal section is set up in tool coordinate system, XdfFor tool coordinate system.When individually setting up coordinate system in normal section, its blade profile is:
Calculate process according to above derivation, the form equation of worm abrasion wheel can be drawn, thus the worm abrasion wheel repairing out needs carries out digital control processing.
Fig. 6 is machine tool main body structural representation, entirety have expressed the primary structure distribution of lathe, wherein: 1 is grinding machine pedestal, and 2 is workpiece clamping table, 3 is work piece holder, 4 is Diamant roller (and thimble) clamping bench, and 5 is emery wheel, and 6 is main shaft rotating motor, 7 is worm abrasion wheel cutter, 8 is online gauge head, and 9 is ball wire rod mechanism, and 10 is machine tool guideway (mainly including the line slideway in tri-directions of X, Y, Z).
