Specific operation process of the present invention is as follows:
(1) the installation adjustment of dynamic poise device
First the present invention is arranged on main shaft according to the direction of bellmouth 4, set nut 6 is installed afterwards, realize the loading of axial pretightening pressure by the threaded engagement between set nut 6 and main shaft, realize the interference fit between the present invention and main shaft, the present invention is fixed on main shaft firmly, in main shaft operational process, also can keeps relative static with main shaft.
Under main shaft stationary state, because the acting force of spring 15 makes anti-fluid ball 14 cavity bottom in hemispherical dome structure 17 all the time, equilibrium liquid flow channel is blocked, prevented that equilibrium liquid from entering and flowing out.
(2) on-line dynamic balancing adjustment
Rotating spindle, when main shaft opens car stable operation under working speed, anti-fluid ball 14 in this process in liquid retainer 3 constantly increases with the required centripetal force of improving constantly of the speed of mainshaft under the action of the centrifugal, the centripetal force of anti-fluid ball 14 stable operations is provided by anti-fluid spring 15, therefore in the time that the needed centripetal force of anti-fluid ball 14 is greater than the elastic force of anti-fluid spring 15 original compression volume productions lifes, anti-fluid spring 15 will be constantly compressed, length is also shorter and shorter, and then provide anti-fluid ball 14 ever-increasing centripetal force, anti-fluid ball 14 also departs from described hemispherical dome structure 17 gradually, thereby make liquid retainer 3 form one and can make the mobile passage of equilibrium liquid.
In the time that the speed of mainshaft is nr/min, the needed centrifugal force of anti-fluid ball 14 is F=m ω
2r
0, wherein, m is anti-fluid ball 14 quality, r
0for its initial position place radius, ω=2 π n/60 is main shaft operation angular velocity, represents spring 15 spring ratios, l with k
0represent spring 15 initial compression length, as F=m ω
2r
0> kl
0time, the reduction length of spring 15 changes, and anti-fluid ball 14 can be separated from hemispherical dome structure 17:
Thereby equilibrium rate n that must anti-fluid ball 14
wfor:
Should first determine that the speed of mainshaft is higher than n main shaft being carried out to transient equilibrium adjustment
wr/min, in the process of adjusting in enforcement transient equilibrium, first balancing liquid is injected in the intake chute 5 on transient equilibrium terminal inner ring 1, because centrifugation will make balancing liquid flow to the bottommost of intake chute 5, and in single intake chute 5, only have a hole path that can make liquid communication, i.e. the liquid retainer 3 of release.
Equilibrium liquid will enter third through-hole 16 and fourth hole 18 successively, from the space of anti-fluid ball 14 and liquid retainer 3 internal layers, flow through, finally enter into equilibrium liquid container cavity 10 by the second through hole 20, because centrifugation makes balancing liquid all the time on the outer wall in equilibrium liquid container cavity 10, thereby change the mass distribution of dynamic poise device, and then adjust the equilibrium state of main shaft.
Can, by changing the balancing liquid in different equilibrium liquid container cavities 10, continue to optimize transient equilibrium effect according to above process, this process implementation chief axis on-line dynamic poise adjustment.
(3) liquid after shutdown keeps
When main shaft is sent after cutoff command, the speed of mainshaft constantly declines, and the required centripetal force of anti-fluid ball 14 also constantly reduces, and anti-fluid spring 15 extends gradually, when the speed of mainshaft is reduced to the equilibrium rate n of anti-fluid ball 14
wafter r/min, spring 15 is pressed in anti-fluid ball 14 in the hemispherical dome structure 17 of liquid retainer 3, liquid flow path in liquid retainer 3 is blocked, be liquid retainer 3 lockings, liquid in equilibrium liquid container cavity 10 cannot be flowed out, even if main shaft rear liquid out of service also can well remain in equilibrium liquid container cavity 10, thereby the liquid of having realized on-line dynamic balancing end device keeps function, when main shaft runs under original working speed again, main shaft is still subject to the impact of balanced termination device inner equilibrium liquid and has good equilibrium state, without carrying out transient equilibrium again, for production and processing, can there is higher work efficiency, has actual application value.
