The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further: with reference to accompanying drawing; The drilling machine advancing mechanism that the swing movable gear internal gear tooth profile of designing connects; Form by CD-ROM drive motor 1, sprocket wheel 2, clamp nut 3, dust seal 4, bearing A5, jackshaft 6, bearing B7, base 8, nut 9, chain 10, carriage 11, chain bolster and driven sprocket 12, sprocket wheel adjusting device 13 and forward beam 14; It is characterized in that: the cross section of sprocket wheel 2 endoporus, jackshaft 6 cylindricals is the equidistant curve of swing movable gear internal gear tooth curve or swing movable gear internal gear tooth curve; Be swing movable gear internal gear tooth curve be by the Swing Movable Teeth Drive principle by its equivalent mechanism be crank and rocker mechanism and degenerate after double-crank mechanism, the swing movable gear internal gear tooth curve that the conjugation transmission obtains; Sprocket wheel 2 endoporus, jackshaft 6 cylindricals cooperate formation swing movable gear internal gear tooth profile keyless, and CD-ROM drive motor 1 is through being bolted on the base 8, and base 8 is through being bolted on the forward beam 14; The output shaft of CD-ROM drive motor 1 connects with jackshaft 6 through key or spline, and jackshaft 6 is bearing on the base 8 through bearing A5 and bearing B7, and bearing A5 left end is equipped with dust seal 4; With 9 pairs of bearing B7 location of jackshaft 6 nut engaged, clamp nut 3 axial restraint sprocket wheels 2, chain 10 1 ends and sprocket wheel 2 engagements; Driven sprocket engagement on the other end and the chain bolster; The chain bolster connects with sprocket wheel adjusting device 13 through rotary pair, is connected with coupling block through rotary pair in the middle of the chain 10, is consolidated with pin on the coupling block; The other end of pin is enclosed within on the carriage 11, and sprocket wheel adjusting device 13 is fixed on the forward beam 14.The hole of swing movable gear internal gear tooth profile and shaft section vertically are columns, or taper; The sprocket bearing axle is that swing movable gear internal gear tooth profile connects or the one manufacturing with the form that connects of driven sprocket 12; Hammer drill and turning power head are fixed on the carriage 11.Hammer drill and turning power head are fixed on carriage 11; The revolution of sprocket wheel 2 drives the rectilinear motion of chain 10, moves down at forward beam 14 through the coupling block on the chain condition 10 and from coupling block pin drive carriage 11.
In order better to understand swing movable gear internal gear tooth curve, further specify as follows:
If z
kBe centre wheel (oscillating tooth internal gear) number of teeth, z
gBe the oscillating tooth number, a is eccentric eccentric throw, and b is equivalent double-crank mechanism length of connecting rod, and centre wheel is fixedly the time, gearratio
(it is eccentric wheel that h corresponds to tie-rod), φ is a parameter with oscillating tooth wheel carrier corner, then obtains the parametric equation of internal gear tooth by the theory of engagement:
What obtain by above-mentioned equation is the oscillating tooth of profile of tooth symmetry, if be crank and rocker mechanism then what obtain is asymmetric oscillating tooth internal gear tooth curve by equivalent mechanism.Symmetry oscillating tooth tooth both sides transmission performance is consistent, generally adopts symmetrical tooth curve.And asymmetric oscillating tooth one side transmission performance is good, and opposite side transmission performance difference is a little, makes forming surface connection rotating drive characteristic different characteristic just in time capable of using and reaches specific requirement.When adopting the two-phase shock wave device, can obtain tooth curve by the theory of engagement equally.When the number of teeth zk of internal gear is odd number, the better effects if of swing movable gear internal gear tooth profile.The present invention is the drilling machine advancing mechanism that swing movable gear internal gear tooth profile connects and uses this profile to connect.The hole that swing movable gear internal gear tooth profile connects is the equidistant curve of swing movable gear internal gear tooth curve and swing movable gear internal gear tooth curve with the cross-sectional boundaries curve of axle.Swing movable gear internal gear tooth curve is the swing movable gear internal gear tooth curve that obtains by Swing Movable Teeth Drive principle (its equivalent mechanism is the double-crank mechanism after crank and rocker mechanism and the degeneration thereof) conjugation transmission.Sprocket wheel endoporus shown in Figure 2 is a=1.2, b=20, z
k=3, z
gThe profile that=4 internal gear tooths obtain.
