It is to be noted; Described in this paper all is that diagrammatic sketch with A-A direction among Fig. 1 is the benchmark definition clockwise, counterclockwise; Just in order to express easily, should be appreciated that clockwise, the counterclockwise explanation that this paper adopts should not limit the scope that the application asks for protection.
In a kind of specific embodiment, the vibrating wheels amplitude modulation mechanism that the utility model provided comprises initiatively eccentric stiffener; Initiatively eccentric stiffener comprises the outer vibrating shaft 11 with inner chamber; Be fixed with eccentric mass on the outer vibrating shaft 11 and be superimposed upon unidirectional first fixed eccentric block 121 and second fixed eccentric block 122, can first fixed eccentric block 121, second fixed eccentric block 122 be connected with outer vibrating shaft 11 through welding or modes such as key connection.
Between first fixed eccentric block 121 and second fixed eccentric block 122, also be provided with movable eccentric block 13; Movable eccentric block 13 is sleeved on the outer vibrating shaft 11; Can be around outer vibrating shaft 11 rotations; First fixed eccentric block 121 or second fixed eccentric block 122 is provided with limit shaft 15 so that the anglec of rotation of restraint eccentric block 13 makes movable eccentric block 13 Rotate 180 degree counterclockwise.
The two ends of vibrating shaft 11 are respectively arranged with first end-cover axle 141 and second end-cover axle 142 outside, can first end-cover axle 141, second end-cover axle 142 be connected with outer vibrating shaft 11 through bolt, and this kind mode is not only easy but also reliable.
First end-cover axle 141, second end-cover axle 142 are connected with clutch shaft bearing seat 61, second bearing support 62 through first vibration bearing 63, second vibration bearing 64 respectively, and the clutch shaft bearing seat 61 and second bearing support 62 are installed on the relevant position of vibrating wheels 7.
One end of second end-cover axle 142 is through yielding coupling 5 and CD-ROM drive motor 4 assemblings, and under the driving of CD-ROM drive motor 4, initiatively eccentric stiffener can rotate counterclockwise or clockwise rotate.
Vibrating wheels amplitude modulation mechanism also comprises driven eccentric stiffener, and driven eccentric stiffener comprises internal vibration axle 21 and driven eccentric block 22; Driven eccentric block 22 can connect with internal vibration axle 21 fixing through welding or key.It is pointed out that also and can internal vibration axle 21 directly be set to eccentric shaft.
Here need to prove that the eccentric mass of the eccentric mass of driven eccentric block 22 and first fixed eccentric block 121 and second fixed eccentric block 122 is superimposed upon same direction when being provided with, and can certainly be superimposed upon rightabout or other directions.
When the active eccentric stiffener rotated under the drive of CD-ROM drive motor 4, because the setting of vibration bearing 65, internal vibration axle 21 transfixions can not rotated with first end-cover axle 141 and second end-cover axle 142.
For internal vibration axle 21 is selectively rotated with the active eccentric stiffener, also be provided with the slidable adjustment device with the end that first end-cover axle 141 is connected at internal vibration axle 21.
The slidable adjustment device comprises handwheel 31, adjustment screw mandrel 32 and two-sided spline housing 33; Two-sided spline housing 33 is positioned at the inner chamber of first end-cover axle 141, and the engagement of the internal spline of its external splines and first end-cover axle 141; The through hole that adjustment screw mandrel 32 passes clutch shaft bearing seat 61, first end-cover axle 141 is connected with two-sided spline housing 33, can will adjust screw mandrel 32 through deep groove ball bearing 34 and be connected with two-sided spline housing 33; The end that adjustment screw mandrel 32 is positioned at clutch shaft bearing seat 61 outsides is fixedly connected with handwheel 31, can connect through bolt, and is not only easy but also reliable.
Through push-and-pull handwheel 31 adjustment screw mandrel 32 is moved at its axis direction, and it is mobile to drive the two-sided spline housing 33 that connects with adjustment screw mandrel 32.In the moving process of adjustment screw mandrel 32, come off in order to prevent deep groove ball bearing 34, jump ring 35 and jam plate 36 can be set to limit the position of deep groove ball bearing 34 between adjustment screw mandrel 32 and two-sided spline housing 33 in the both sides of deep groove ball bearing 34.
When adjusting screw mandrel 32, can promote two-sided spline housing 33 and be connected, even the engagement of the external splines of the internal spline of two-sided spline housing 33 and internal vibration axle 21 with internal vibration axle 21 to first end-cover axle, 141 medial movement.At this moment; When initiatively eccentric stiffener rotates under the driving of CD-ROM drive motor 4; Because two-sided spline housing 33 and 141 engagements of first end-cover axle; So two-sided spline housing 33 also along with rotating together, rotates thereby drive with the internal vibration axle 21 of two-sided spline housing 33 engagements and the driven eccentric block 22 that is fixedly connected with internal vibration axle 21.
When making adjusting screw mandrel 32 drive two-sided spline housing 33, moves laterally by pulling handwheel 31; When thereby the external splines that makes internal spline and the internal vibration axle 21 of two-sided spline housing 33 is thrown off; Under the effect of CD-ROM drive motor 4; The active eccentric stiffener only drives two-sided spline housing 33 and rotates together, and internal vibration axle 21 and the driven eccentric block 22 that is fixedly connected with it keep static.
Here need to prove, the above-mentioned outside and inboard be with near or be that benchmark defines away from the inner chamber of outer vibrating shaft 11, the description in this orientation should not limit the scope that the application asks for protection.
Because driving at CD-ROM drive motor 4 with adjustment screw mandrel 32, the setting of deep groove ball bearing 34, handwheel 31 all keep inactive state when initiatively eccentric stiffener rotates.
So through slide adjuster driven eccentric stiffener is selectively rotated with the active eccentric stiffener, thereby the output amplitude that can make vibrating wheels becomes four kinds by original two kinds, concrete state is described below.
First kind of amplitude: regulate slide adjuster 3; Make internal vibration axle 21 and two-sided spline housing 33 be in not engagement (being shown among Fig. 4); CD-ROM drive motor 4 drives initiatively, and eccentric stiffener clockwise rotates (being shown among Fig. 2); This moment outer vibrating shaft 11 first fixed eccentric block 121, second fixed eccentric block 122 and movable eccentric block 13 in same sideway swivel, eccentric mass superposes; Driven eccentric stiffener does not rotate, and this moment, output amplitude was C;
