The specific embodiment:
Embodiment: the present invention comprises a pair of vibrating shaft (1), (2) and combined eccentricity piece (18) thereof, (19), differential driving gear box (3), excitation power source (7), cylinder (20), motor (9) shown in Fig. 1,2,3,4.Differential driving gear box (3) comprises power shaft (10), right and left central gears (11), (12), idle wheel (13), (14), power transmission shaft (15), (16), casing (17).Two vibrating shafts (1), (2) are symmetrically distributed in the both sides of vibrating wheels (22) center line O-O, respectively be provided with one group of eccentric block (18), (19) on vibrating shaft (1), (2), vibrating shaft (1), (2) by bearings on cylinder (20), cylinder (20) and frame (21) join together, the two ends of cylinder (20) by bearings on vibrating wheels (22).Excitation power source (7) links by shaft coupling (6) and exciting power transmission shaft (5), exciting power transmission shaft (5) links with vibrating shaft (1) by exciting travelling gear (41), (42), be excited at the same time power shaft (10), differential driving gear box (3), output gear (24), the exciting travelling gear (43) of power transmission shaft (5) by shaft coupling (23), differential driving gear box (3) and link with vibrating shaft (2) again, thereby drive two combined eccentricity pieces (18), (19) are done with the rotating speed opposite spin.
In the casing (17) of differential driving gear box (3) two power transmission shafts (15), (16) are arranged, be supported on respectively on the bearing of casing (17) relevant position.Power transmission shaft (15), (16) respectively connect firmly an idle wheel on, LC gear (11) connects firmly on power shaft (10), the part of idle wheel (13) facewidth on the power transmission shaft (15) and LC gear (11) engagement, the part engagement of idle wheel (14) facewidth on another part of the facewidth and the power transmission shaft (16), another part of idle wheel (14) facewidth and right central gear (12) engagement, make idle wheel (14) and axially dislocation layout of LC gear (11), both can not interfere, each gear number of teeth is set and should be satisfied gear (42) and gear rotating speeds such as (43), right central gear (12) and output gear (24) connect firmly and are integral, and by bearings on power shaft (10) and casing (17).The left end of power shaft (10) is by casing (17) left end of bearings in differential driving gear box (3), power shaft (10) right-hand member by bearings on garden tube (20), differential driving gear box (3) left end directly is supported on the central bearing of cylinder (20) left end, or is supported on by power shaft (10) on the central bearing of cylinder (20) left end.Differential driving gear box (3) is connected with motor (9) on being fixed on frame (21) by adjusting axle (8).
Operating principle: supposed that the revolution axial line O1-O1 of two vibrating shafts (1), (2), the plane of O2-O2 were called the P-P plane, and crossed vibrating wheels (22) center line O-O and be called Q-Q perpendicular to the plane on P-P plane.Exciting force vector when combined eccentricity piece (18) generation
Exciting force vector with combined eccentricity piece (19) generation
(wherein
) when the Q-Q plane symmetry distributed relatively, the resultant direction of two groups of eccentric block generation exciting forces was all the time perpendicular to plane P-P (shown in Fig. 2,4), the exciting resultant direction is perpendicular to being compacted ground, and promptly vibrating wheels (22) is done the vertical orientation vibration; When the starting phase angle of the eccentric throw vector of combined eccentricity piece (18) constant, and the starting phase angle of the eccentric throw vector of combined eccentricity piece (19) is when changing the β angle, then the resultant direction of two groups of eccentric block generation exciting forces becomes β/2 angles with the Q-Q plane, vibrating wheels (22) is done hybrid vibration, and the size of vertical vibration component and horizontal vibration component depends on β/2 jiao.In the time of β/2=90 °, vibrating wheels (22) is done the oscillatory type vibration, and its vertical vibration component is zero.
Its transmission process is that excitation power source (7) drives exciting power transmission shaft (5) rotation by shaft coupling (6), the exciting travelling gear (42) that exciting travelling gear (41) on the exciting power transmission shaft (5) drives on the vibrating shaft (1) rotates, thereby the combined eccentricity piece (18) that drives on the vibrating shaft (1) rotates, be excited at the same time power transmission shaft (5) and drive power shaft (10) rotation by shaft coupling (23), the LC gear (11) that then is fixed on the power shaft (10) drives idle wheel (13) successively, idle wheel (14), right central gear (12) rotates, right central gear (12) drives co-axially fixed output gear (24) and rotates, output gear (24) drives the exciting travelling gear (43) that is fixed on the vibrating shaft (2) and rotates, thereby the combined eccentricity piece (19) that drives on the vibrating shaft (2) rotates.Because the transition of differential gearing, thus two combined eccentricity pieces (18), (19) rotation direction each other oppositely and etc. rotating speed.
When adjusting vibration mode, rely on motor (9) or oscillating motor to drive differential driving gear box (3) unitary rotation by adjusting axle (8), because of the LC gear (11) of differential driving gear box (3) connects firmly mutually with power shaft (10), suppose power shaft (10), shaft coupling (23) and exciting power transmission shaft (5) relative fixed are motionless, then make idle wheel (13) (being planetary gear) do planetary rotation around LC gear (11), drive idle wheel (14) successively, right central gear (12), output gear (24), exciting travelling gear (43), vibrating shaft (2), combined eccentricity piece (19) rotates, thereby makes the combined eccentricity piece (19) on the vibrating shaft (2) obtain additional rotation.According to cyclic train gearratio principle, if the casing (17) of differential driving gear box (3) (annotate: be equivalent to tie-rod) turns over β/2 jiao, then the additional rotation angle of combined eccentricity piece (19) is the β angle, even the starting phase angle of the eccentric throw vector of combined eccentricity piece (19) changes β angle (as shown in Figure 4), suppose that eccentric block this moment (18) is motionless, cause two eccentric blocks to produce making a concerted effort of exciting force
Direction changes β/2 jiao.Therefore, can rely on motor (9) or oscillating motor to drive combined eccentricity piece (19) and make additional rotation by adjustment axle (8), a differential driving gear box (3), output gear (24), exciting travelling gear (43), vibrating shaft (2), starting phase angle until the eccentric throw vector that makes combined eccentricity piece (19) turns over predetermined angle, obtain predetermined vibration mode, and carry out exciting with this vibration mode.The corner of (that is: under exciting state or the non-exciting state) stepless adjustment differential driving gear box (3) in the course of the work in any case, make the starting phase angle of the eccentric throw vector of combined eccentricity piece (19) turn over predetermined angle, thereby reach the adjustment of vibration mode.The adjustment excursion 0～A of the vertical vibration component of each vibration mode and oscillating component (annotate: A is the maximum perpendicular amplitude), concrete size depends on the angle on exciting resultant direction and Q-Q plane.
