Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
See also accompanying drawing, coupling 1 of the present invention is installed on the frame 12, be used for being connected with power source, one end of crank 2 achieves a fixed connection by axle A and coupling 1, the other end is hinged by an end of axle E and one-level connecting rod 3, and the other end of one-level connecting rod 3 is hinged by the middle part of axle F and one-level rocking bar 11; The oscillation center of one-level rocking bar 11 1 ends is hinged by axle B and frame 12, and the other end is hinged by an end of axle G and secondary connecting rod 4; The other end of secondary connecting rod 4 is hinged with the middle part of rocking bar 8 in parallel by axle H; The oscillation center of rocking bar 8 one ends in parallel is hinged by axle C and travelling nut 7, and the other end is hinged by an end of axle M and three grades of connecting rods 9; The other end of three grades of connecting rods 9 is hinged with an end of output rocking bar 10 by axle N, and the oscillation center of output rocking bar 10 the other ends is hinged with frame 12 by axle B '; The two ends of screw mandrel 6 are installed on the frame 12, and its middle revolving by the screw in the middle of screw thread and the travelling nut 7 is joined; Control gear 5 is connected an end end of screw mandrel 6.Wherein: constitute first order quadratic crank mechanism by the one-level rocking bar 11 between the one-level connecting rod 3 between the crank 2 between axle A and the axle E, axle E and the axle F, axle F and the axle B, constitute second level quadratic crank mechanism by the rocking bar in parallel 8 between the secondary connecting rod 4 between the one-level rocking bar 11 between axle B and the axle G, axle G and the axle H, axle H and the axle C, output rocking bar 10 between three grades of connecting rods 9, axle N and the axle B ' by axle C and axle between rocking bar in parallel 8, axle M and the axle N between the M constitutes third level quadratic crank mechanism, between three grade of four connecting rod for being connected in series.
Please continue to consult accompanying drawing, be quadrature between the line of axle B, B ' of the present invention and the screw mandrel 6, and axle B, B ' are positioned on the same shaft axis in the horizontal plane direction.In described first order quadratic crank mechanism, the bar major axis B on the one-level rocking bar 11 arrives the distance of axle E greater than the bar major axis A on the crank 2 to the distance of axle F; In the quadratic crank mechanism of the described second level, the bar major axis B on the one-level rocking bar 11 arrives the distance of axle H greater than the bar major axis C on the rocking bar 8 in parallel to the distance of axle G; In described third level quadratic crank mechanism, the bar major axis C on the rocking bar 8 in parallel arrives the distance of axle B ' greater than the bar major axis N on the output rocking bar 10 to the distance of axle M.Its effect is to make the pivot angle of the pivot angle of rocking bar 8 in parallel greater than one-level rocking bar 11, and the pivot angle of output rocking bar 10 is greater than the pivot angle of rocking bar 8 in parallel, makes the maximum amplification of the output pivot angle of output rocking bar 10 can reach four times of pivot angle of one-level rocking bar 11.Here need to prove: rotate when control gear 5 drives screw mandrel 6, cause travelling nut 7 to axle B, when B ' direction moves, the output pivot angle scope of output rocking bar 10 will diminish gradually, when travelling nut 7 moves to limit position (i.e. the neutral position of axle B, B ' line), the pivot angle scope of output pivot angle is the pivot angle of one-level rocking bar 11, this is a minimum value, is about 30 °.
Narrate working procedure of the present invention below in conjunction with accompanying drawing: at first, give coupling 1 by power source with transmission of power, drive crank 2 by coupling 1 and make circular movement, the circular movement of crank 2 drives one-level connecting rod 3, drive one-level rocking bar 11 by one-level connecting rod 3 again, make one-level rocking bar 11 make reciprocally swinging around oscillation center axle B, the reciprocally swinging of one-level rocking bar 11 drives the secondary connecting rod 4 in the quadratic crank mechanism of the second level again successively, rocking bar 8 in parallel, make rocking bar 8 in parallel make reciprocally swinging around oscillation center axle C, in this process, because the bar major axis B on the one-level rocking bar 11 arrives the distance of axle E greater than the bar major axis A on the crank 2 to the distance of axle F, and the bar major axis B on the one-level rocking bar 11 arrives the distance of axle H greater than the bar major axis C on the rocking bar 8 in parallel to the distance of axle G, the pivot angle that the pivot angle that makes rocking bar 8 in parallel swing around oscillation center axle C is swung around oscillation center axle B greater than one-level rocking bar 11, so second level quadratic crank mechanism is a pivot angle enlarger.In like manner, the reciprocally swinging of rocking bar 8 in parallel, drive three grades of connecting rods 9 again successively, output rocking bar 10, make output rocking bar 10 make reciprocally swinging around oscillation center axle B ', in this process, because the bar major axis C on the rocking bar 8 in parallel arrives the distance of axle B ' greater than the bar major axis N on the output rocking bar 10 to the distance of axle M, make and export the pivot angle that rocking bar 10 is swung around oscillation center axle C greater than rocking bar 8 in parallel around the pivot angle of oscillation center axle B ' swing, therefore third level quadratic crank mechanism also is a pivot angle enlarger of second level quadratic crank mechanism, and the pivot angle of output rocking bar 10 is further amplified.
In real work, when the pivot angle size of output rocking bar 10 and swaying movement regularity require variation according to reality, can realize by control gear 5, control gear 5 both can adopt manually, also can adopt automatic control, when adopting manually-operable, control gear 5 is generally selected handwheel for use, handwheel is installed in an end end of screw mandrel 6, when operator's rotation hand wheel, can drive screw mandrel 6 rotates together, rotatablely moving and driving travelling nut 7 of screw mandrel 6 moved on screw mandrel 6, and the position of the oscillation center axle C of rocking bar 8 in parallel is changed, thereby changed second simultaneously, the frame length and the position of third level quadratic crank mechanism change the pivot angle size of output rocking bar 10; When adopting operation automatically, control gear 5 is generally selected the automatic controller that is made of stepper motor and programmable controller PLC for use, driving screw mandrel 6 by stepper motor rotates, programmable controller PLC can weave control program in advance according to job requirement, can automatically realize online real-time speed change.When screw mandrel 6 rotation drive travelling nuts 7 move, the oscillation center axle C of rocking bar 8 in parallel is close towards axle B, B ' direction, make second and the angle enlarging function of third level linkage mechanism weaken, as oscillation center axle C (being travelling nut 7) when entering between a B, the B ', second, third grade fourbar linkage does not play the pivot angle amplification, and the pivot angle size of promptly exporting rocking bar 10 is identical with one-level rocking bar 11.Therefore, displacement amount and the pivot angle magnification factor of oscillation center axle C have corresponding relation, and the displacement of oscillation center axle C is at the instantaneous state that can not change output rocking bar 10.
The present invention both can be made into the speed changer of independent similar traditional gearbox in actual production, also can be used as a transmission module in the machinery.
