Specific implementation mode
In order to deepen the understanding to the utility model, the utility model is made with reference to the accompanying drawings and examples further detailed
Thin explanation.Following embodiment is only used for clearly illustrating the technical solution of the utility model, and cannot be limited with this
The scope of protection of the utility model.
As in Figure 2-4, a kind of stepless-adjustment amplitude of the utility model, self-lubricating vibrator, including motor, shaft coupling,
Main shaft, bearing and bearing block, motor are connect by shaft coupling with main shaft, and bearing holder (housing, cover) is set on main shaft, and bearing is installed on bearing
It is also arranged with main eccentric block and secondary eccentric block on seat, on main shaft, adjustment oil cylinder is installed on main eccentric block, adjusts and is connected on oil cylinder
There are the first oil inlet pipe and the second oil inlet pipe, one end of the first oil inlet pipe and the second oil inlet pipe is all connected with fueller, the first oil inlet
The other end of pipe and the second oil inlet pipe passes through main eccentric block and secondary eccentric block to be connected with oil return pipe, and oil return pipe connects with fueller

2, fueller works, the first oil inlet pipe oil inlet, the second oil inlet pipe oil return；
3, adjustment oil cylinder stretches out, and drives secondary eccentric block to rotate clockwise, changes angle, secondary eccentric block is overlapped with main eccentric block
Volume reduces, and amplitude becomes smaller.
Two, amplitude is tuned up
1, oil return pipe is closed；
2, fueller works, the second oil inlet pipe oil inlet, the first oil inlet pipe oil return；
3, adjustment oil cylinder retraction drives secondary eccentric block to rotate counterclockwise, changes angle, and secondary eccentric block is overlapped with main eccentric block
Volume becomes larger, and amplitude becomes larger.
Three, oil return pipe is opened after amplitude adjustment, forms cycle self-lubricating.
Stepless adjust automatically can be achieved in stepless-adjustment amplitude, the self-lubricating vibrator of this practicality in adjustable extent.
As shown in figure 4, the included angle in figure at A i.e. to change after main eccentric block and eccentric block adjustment.
It is noted that embodiment described above is to the illustrative and not limiting of technical solutions of the utility model, affiliated skill
