The other end of X-axis reel cage 2, Y-axis reel cage 3 links to each other with separately drive unit respectively.Drive unit mainly comprises: power generating mechanism 9, harmonic vibration generating mechanism 10, harmonic vibration--swing throw-over gear 11.Its medium power generating mechanism 9 is made of motor and step-down gear 9-1 and driving toothed gear 9-2.
In the harmonic vibration generating mechanism 10, a sun-wheel 10-1 who meshes with driving toothed gear 9-2 is arranged, the side of sun-wheel 10-1 has one to be the planet axis 10-2 of sun-wheel 10-1 pitch radius apart from its axle center, the sun and planet gear 10-3 that has a pitch radius to equate on the planet axis 10-2 with sun-wheel 10-1 pitch radius, one minor axis is also arranged resonance output shaft 10-4 on the sun and planet gear 10-3 pitch circle, the outside of sun and planet gear 10-3 then is with an internal tooth pitch radius and equals sun-wheel 10-1 pitch circle diameter just, axle center with sun-wheel 10-1 is the annulus gear 10-5 at center, engagement in annulus gear 10-5 internal tooth figure and the sun and planet gear 10-3, the gear teeth on the outer shroud and a tilt adjustment gear 10-6 engagement, the outer flank of tooth of annulus gear 10-5 can be 90 ° sector, and tilt adjustment gear 10-6 is driven by a dedicated motor and step-down gear 10-7.
In harmonic vibration--in the swing throw-over gear 11, resonance output shaft 10-4 is attached thereto by a T-socket I11-1, and T-socket I11-1 is sleeved on the slide bar 11-2, and slide bar 11-2 is then with a set of bell cranks--linkage assembly links to each other.In this group mechanism, the between centers between X-axis reel cage 2 and the stationary shaft 11-3, the length of long connecting rod 11-4, the length three of slide bar 11-2 equate.The length three of top short connecting rod 11-5, bottom short connecting rod 11-6, short crank 11-8 is also equal, and equals long crank 11-7 length half.The end of this foreign minister's crank 11-7 is fixed on the X-axis reel cage 2, and its middle is connected with bottom short connecting rod 11-6, and the other end links to each other with slide bar 11-2 through T-socket II11-9, and T-socket I11-1, T-socket II11-9 can slide on slide bar 11-2.Like this, slide bar 11-2 is just all the time with this set of bell cranks--linkage assembly is formed two parallelogram planar linkage mechanisms that can change.
As shown in Figure 2, the motion principle of above-mentioned resonance generating mechanism is as follows: fasten at the abscissa of plane coordinates and get the A point, get the B point on the vertical seat bar, make line AB, if AB length is constant, and the A point can only move on abscissa, and the B point can only move on ordinate, then the track of AB line mid point C is to be the center of circle with the coordinate center O, and OC is a circle (circle in claiming) of radius.Be the center of circle with the O point again, the AB line length is that radius is made circle (title cylindrical), and then the projection of intersection point D on abscissa of the extended line of OC line and cylindrical is exactly the A point.When the C point when interior circle at the uniform velocity rotates, the D point also with identical constant angular velocity along outer circular motion, the projection A point that D is ordered is just done harmonic vibration on abscissa.In the harmonic vibration generating mechanism of reality, interior circle is replaced by sun-wheel 10-1, the C point is exactly planet axis 10-2, the AB line replaces with sun and planet gear 10-3, the A point is exactly resonance output shaft 10-4, cylindrical is replaced by the ring gear of annulus gear 10-5, and the D point is exactly the mesh point of the ring gear of sun and planet gear and annulus gear 10-5.
The cloth process of first kind of embodiment of oscillating chute type blast furnace charging in bell-less top device of the present invention is as follows: down moving at motor and step-down gear 9-1 district, driving toothed gear 9-2 rotates; Sun-wheel 10-1 at the uniform velocity rotation under the engagement of driving toothed gear 9-2 drives, planet axis 10-2 on the sun-wheel 10-1 just promotes sun and planet gear 10-3 engagement rolling in the ring gear of annulus gear 10-5, and resonance output shaft 10-4 will do the collinear harmonic vibration along a diameter among the annulus gear 10-5.
When resonance output shaft 10-4 does the straight line harmonic vibration, slide bar 11-2 realizes translational movement by T-socket I11-4, the slide bar 11-2 of translation is by the planar linkage mechanism of T-socket II11-9 and bottom short connecting rod 11-6 and long connecting rod 11-4 formation back and forth, promote long crank 11-7 swing, long crank 11-7 promotes 2 swings of X-axis reel cage again.
