Movable eccentric block 1 is the eccentric block with internal thread segment L, for being loaded into one-piece parts behind the easily manufactured employing parts processing, between the split of movable eccentric block 1 intermediate annular groove is arranged, fixed eccentric block 2 is the eccentric blocks with internal spline, be processed with erection loop with its axis of rotation, movable eccentric block adapter ring groove width S
1Should be greater than fixed eccentric block erection loop wall thickness S
2The intermediate annular groove of the erection loop insertion activity eccentric block 1 of fixed eccentric block 2, folding freely between movable eccentric block 1 and the fixed eccentric block 2, vibrating shaft 3 band external splines, pore area internal thread segment K in it, be assemblied on the vibrating shaft 3 after movable eccentric block 1 and fixed eccentric block 2 combinations, vibrating shaft 3 is assemblied on the vibration bearing 9, between movable eccentric block 1 and vibration bearing 9, eseparation ring 11 is housed, the external diameter of eseparation ring 11 and thickness require to decide according to the installation dimension of vibration bearing 9, and certainly, stripper loop 11 also can be made Same Part with movable eccentric block 1, motion thread axle 7 is with two sections external screw threads, and motion thread axle the first thread segment M and vibrating shaft internal thread segment K match; Motion thread axle the second thread segment N and movable eccentric block internal thread segment L match, and push-and-pull bearing 6 is housed on the motion thread axle 7, and push-and-pull bearing 6 is installed in the push-pull shaft bearing 5, and push-pull shaft bearing 5 is connected connection with push-pull mechanism.
But the preferred typical structure embodiment of the vibrator of vibrating roller of a kind of continuous setup eccentricity that the utility model provides the course of work as follows: one, the eccentricity adjustment process of vibrator is: under Fig. 6, ultimate limit state shown in Figure 7, when push-pull mechanism 4 was passed motion thread axle 7 by push-pull shaft bearing 5, push-and-pull bearing 6 to vibrating motor mechanism 8 directions, movable eccentric block 1 was made clockwise direction and is rotated; Fixed eccentric block 2 is for counterclockwise rotation (such as Fig. 8, shown in Figure 9, this moment is for to stand in an end face of vibrating motor mechanism 8 to movable eccentric block 1 and fixed eccentric block 2, motion thread axle the first thread segment M is that left-handed, motion thread axle the second thread segment N is dextrorotation), eccentric block deciliter angle β becomes large, and the eccentricity that closes of movable eccentric block 1 and fixed eccentric block 2 diminishes; When push-pull mechanism 4 deviated from motion thread axle 7 vibrating motor mechanism 8 directions and passes by push-pull shaft bearing 5, push-and-pull bearing 6, movable eccentric block 1 was for counterclockwise rotation; Fixed eccentric block 2 is made clockwise direction and is rotated, an eccentric block deciliter angle β diminishes, the eccentricity that closes of movable eccentric block 1 and fixed eccentric block 2 becomes large, two, the exciting process of vibrator is: vibrating motor mechanism 8 drives motion thread axle 7 and makes High Rotation Speed, and motion thread axle 7 meshes by motion thread axle the second thread segment N and movable eccentric block internal thread segment L and transmission activity eccentric block 1 is made High Rotation Speed; Motion thread axle 7 meshes by motion thread axle the first thread segment M and vibrating shaft internal thread segment K and transmission vibration axle 3 is made High Rotation Speed, vibrating shaft 3 is made High Rotation Speed by internal spline engagement and the transmission fixed eccentric block 2 of its external splines and fixed eccentric block 2 again, the centrifugal force that produces during combined eccentricity piece High Rotation Speed is by vibration bearing 9, vibrating shaft bearing 10(namely vibrates the spoke version) pass to steel wheel, make steel wheel produce vibration, actuating speed one timing when vibrating motor mechanism 8, movable eccentric block 1 and fixed eccentric block 2 to close eccentricity larger, the centrifugal force of its generation larger (exciting force that also is steel wheel is larger), because the effect of push-and-pull bearing 6, push-pull mechanism 4 and push-pull shaft bearing 5 do not rotate.
But in the preferred typical structure embodiment of the vibrator of vibrating roller of a kind of continuous setup eccentricity that the utility model provides, need to prove:
One, the eccentricity of movable eccentric block 1 and fixed eccentric block 2 approach to equate, then during the variable quantity of corresponding same eccentric block deciliter angle β, two eccentric blocks to close the eccentricity variable quantity larger.
When two, the rotation direction of movable eccentric block internal thread segment L and vibrating shaft internal thread segment K opposite (i.e. one section left-handed another section dextrorotation) and helical pitch are identical, then corresponding motion thread axle 7 moves axially distance one regularly, the variable quantity of eccentric block deciliter angle β more namely two eccentric blocks to close the eccentricity variable quantity larger; Simultaneously, the axial force that movable eccentric block internal thread segment L and vibrating shaft internal thread segment K produce when eccentric block rotates is offset at motion thread axle 7, makes push-pull mechanism 4 not bear extra load.
Three, the lead of movable eccentric block internal thread segment L and vibrating shaft internal thread segment K is less, then corresponding motion thread axle 7 moves axially distance one regularly, the variable quantity of eccentric block deciliter angle β more namely two eccentric blocks to close the eccentricity variable quantity larger, but the working resistance of push-pull mechanism 4 is larger.
Four, when the thread rotary orientation of movable eccentric block internal thread segment L and vibrating shaft internal thread segment K is identical, then both leads must be unequal, when motion thread axle 7 moves axially, movable eccentric block 1 and vibrating shaft 3(are fixed eccentric block 2) the change eccentric block deciliter angle β circumferentially realizing differential, but motion thread axle 7 moves axially distance one regularly, the variable quantity of eccentric block deciliter angle β diminishes namely, and the eccentricity variable quantity that closes of two eccentric blocks diminishes, and the axial force that movable eccentric block internal thread segment L and vibrating shaft internal thread segment K produce when eccentric block rotates can superpose at motion thread axle 7, makes push-pull mechanism 4 bear extra load.
Five, can change the arbitrary thread segment among movable eccentric block internal thread segment L or the vibrating shaft internal thread segment K into straight-tooth is spline, another section still is thread segment, can realize that also motion thread axle 7 moves axially the purpose that changes eccentric block deciliter angle β, make it to bear extra load but the axial force that movable eccentric block internal thread segment L or vibrating shaft internal thread segment K produce can pass to push-pull mechanism 4 when the eccentric block rotation of correspondence.
Six, when movable eccentric block 1 split was fabricated to dismantled and assembled structure, fixed eccentric block 2 can be fixedly connected with or make Same Part with vibrating shaft 3.
Realization of the present utility model, the embodiment manufacturing technology routinely that provides by accompanying drawing gets final product.
