Novel it is described in detail.
As it is shown in figure 1, pumping chamber 1 is the cylindrical metal part of open at both ends, pumping chamber 1 is built with piston 2 and supercharging tooth
Abaculus 4, equipped with pressurized spring 3 between piston 2 and supercharging dental inlay block 4, piston 2 is full of hydraulic oil above, drives dental inlay block 5 to pass through
Angular contact ball bearing is arranged on bottom, pumping chamber 1, and worm gear 7 is arranged on driving dental inlay block 5 lower end, is fixed by nut 9, worm screw 8
Being arranged on lower end, pumping chamber 1, engage with worm gear 7, worm screw 8 one end is connected with motor 11, and base 10 is threaded connection and is arranged on
Bottom, pumping chamber 1.
As shown in Figure 4, Figure 5, supercharging dental inlay block 4 and driving dental inlay block 5 have spiral facing, during installation, and spiral facing phase
Contact mutually, when motor 11 drives worm screw 8 to rotate, due to the engagement between worm screw 8 and worm gear 7, worm gear 7 also can rotate,
Worm gear 7 drives and drives dental inlay block 5 to rotate, and drives dental inlay block 5 to be contacted by spiral facing between supercharging dental inlay block 4, drives tooth
The rotation of abaculus 5 can make supercharging dental inlay block 4 move up and down, thus supercharging dental inlay block can realize the compression to pressurized spring 3,
When supercharging dental inlay block 4 moves up, pressurized spring 3 is compressed, and the hydraulic fluid pressure on piston 2 top increases, when supercharging dental inlay block
4 pressurized spring 3 decrements when moving down reduce, and the hydraulic fluid pressure on piston 2 top reduces.Thus achieve by outside
Regulation changes the function of frcition damper interior oil hydraulic coupling.
Illustrate as a example by a kind of frcition damper below.
As shown in Figure 6, frcition damper includes upper shell 121, operating bar 122, upper cover 123, swelling inner sleeve 124, swelling
Overcoat 125, inner core 126, rubber bodies 127 and spiral friction plate 128, inner core 126 is cylinder-like structure and vertically places, inner core

Housing upper is connected with focus by hinge.During work, focus drives upper shell vibration, is applied to the active force effect of upper shell
On operating bar, operating bar is inserted in inner core after end cap, owing to being full of fluid in inner core, when operating bar is with upper shell
Time in motion press-in inner core, oil liquid pressure increases and acts in rubber bodies by the oil through on inner core, makes rubber bodies become
Shape, the diameter of rubber bodies increases the nominal diameter increase making to be enclosed within the spiral friction plate outside rubber bodies, at this moment spiral friction
Produce extrusion friction between plate and upper enclosure inner wall, produce friction damping force to reach the effect of damping.Operating bar press-in inner core
In length the biggest, the oil liquid pressure in inner core is the biggest, and the frictional force between spiral friction plate and upper shell is the biggest, and so this rubs
Wipe antivibrator and can automatically adjust the size of friction damping force according to external load size, to produce correspondingly sized frictional force.
Friction damping force changes with the change of amplitude, and vibration source eliminates rear screw friction plate and restores to the original state, and improves spiral friction plate
Service life.Owing to being that motor drives pressurizer, so antivibrator can regulate down the fluid pressure in inner core in working order
Power, and then the damping characteristic of antivibrator can be changed down in working order.
