The specific embodiment
The structure principle chart that now contrasts the preferred typical structure embodiment of a kind of vibrator of vibrating roller that can continuous setup eccentricity provided by the invention is illustrated, a kind of eccentric block in can the vibrator of vibrating roller of continuous setup eccentricity provided by the invention is combined eccentricity piece, by movable eccentric block 1 and fixed eccentric block 2, by vibrating shaft 3, fit together and be arranged on vibrating shaft bearing 10 by vibration bearing 9 and vibrate in spoke version, in the endoporus of movable eccentric block 1 and vibrating shaft 3, pass motion thread axle 7, one end of motion thread axle 7 is connected with vibrating motor mechanism 8, the other end is by push-and-pull bearing 6, push-pull shaft bearing 5 is connected with push-pull mechanism 4.
Movable eccentric block 1 is the eccentric block with internal thread segment L, for being loaded into one-piece parts after easily manufactured employing parts processing, between the split of movable eccentric block 1, there is intermediate annular groove, fixed eccentric block 2 is the eccentric blocks with internal spline, with its axis of rotation, be processed with erection loop, movable eccentric block adapter ring groove width S
1should be greater than fixed eccentric block erection loop wall thickness S
2, the intermediate annular groove of the erection loop insertion activity eccentric block 1 of fixed eccentric block 2, between movable eccentric block 1 and fixed eccentric block 2, folding freely, vibrating shaft 3 band external splines, pore area internal thread segment K in it, after movable eccentric block 1 and fixed eccentric block 2 combinations, be assemblied on vibrating shaft 3, vibrating shaft 3 is assemblied on 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 determine according to the installation dimension of vibration bearing 9, certainly, stripper loop 11 also can be made Same Part with movable eccentric block 1, motion thread axle 7 is with two sections of external screw threads, 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 motion thread axle 7, and push-and-pull bearing 6 is arranged in push-pull shaft bearing 5, and push-pull shaft bearing 5 is connected with push-pull mechanism 4.
The preferred typical structure embodiment of a kind of vibrator of vibrating roller that can continuous setup eccentricity provided by the invention the course of work as follows: one, the eccentricity adjustment process of vibrator is: under the ultimate limit state shown in Fig. 6, Fig. 7, when push-pull mechanism 4 is 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 rotates clockwise, fixed eccentric block 2 is for counterclockwise rotation (as shown in Figure 8, Figure 9, now for standing in one end facing movament eccentric block 1 and the fixed eccentric block 2 of vibrating motor mechanism 8, 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 deviates from the 8 directions passing of vibrating motor mechanism by push-pull shaft bearing 5, push-and-pull bearing 6 by motion thread axle 7, movable eccentric block 1 is for counterclockwise rotation, fixed eccentric block 2 rotates clockwise, 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 to make 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 the transmission fixed eccentric block 2 of its external splines and fixed eccentric block 2 again, the centrifugal force producing during combined eccentricity piece High Rotation Speed is by vibration bearing 9, vibrating shaft bearing 10(vibrates 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 larger (exciting force that is also steel wheel is larger) of its generation, effect due to push-and-pull bearing 6, push-pull mechanism 4 and push-pull shaft bearing 5 do not rotate.
In the preferred typical structure embodiment of a kind of vibrator of vibrating roller that can continuous setup eccentricity provided by the invention, it should be noted that:
One, the eccentricity of movable eccentric block 1 and fixed eccentric block 2 approach to equate, during the variable quantity of corresponding same eccentric block deciliter angle β, two eccentric blocks to close eccentricity variable quantity larger.
When two, the rotation direction of movable eccentric block internal thread segment L and vibrating shaft internal thread segment K contrary (i.e. one section of left-handed another section of dextrorotation) and helical pitch are identical, corresponding motion thread axle 7 moves axially distance one regularly, the variable quantity of eccentric block deciliter angle β more two eccentric blocks to close eccentricity variable quantity larger; Meanwhile, 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 on 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, corresponding motion thread axle 7 moves axially distance one regularly, the variable quantity of eccentric block deciliter angle β more two eccentric blocks to close 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, 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) circumferentially realizing differential, change eccentric block deciliter angle β, but motion thread axle 7 moves axially distance one regularly, the variable quantity of the eccentric block deciliter angle β i.e. eccentricity variable quantity that closes of two eccentric blocks that diminishes 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 on motion thread axle 7, make push-pull mechanism 4 bear extra load.
Five, can change the arbitrary thread segment in movable eccentric block internal thread segment L or vibrating shaft internal thread segment K into straight-tooth is spline, another section is still thread segment, also can realize motion thread axle 7 and move axially the object that changes eccentric block deciliter angle β, but the axial force that movable eccentric block internal thread segment L or vibrating shaft internal thread segment K produce when corresponding eccentric block rotation can pass to push-pull mechanism 4, make it to bear extra load.
Six, when movable eccentric block 1 split is 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 invention, the embodiment providing by accompanying drawing manufacturing technology routinely.
