Mode of execution:
Main design of the present invention is: this device is installed in unbalanced rotor shaft shoulder position.This device scribbles the end cap window 7 that absorbs the heat energy material, seal ring 3 and 6, sleeve, pneumatic piston 2, air valve 4, infrared source 9 etc. by hollow shaft part 1, bearing (ball) cover 5, surface and partly forms, pneumatic piston 2 and air valve 4 are installed in respectively in the cavity of the hollow shaft part 1 in four chambeies, end cap window 7 is installed on the bearing (ball) cover 5, bearing (ball) cover 5 is installed in hollow shaft part 1 two ends respectively, shaft part is fastened on the unbalanced rotor by sleeve, above-mentioned good air-proof condition is installed.When a certain side of determining rotor is uneven, detect amount of unbalance information such as uneven direction, quality and phase place by sensor, determine the load balance condition, automatically control air valve 4 increases the pressure of reverse cavity, and when rotor rotation time control heats source of radiation 9 these end cap windows of heating, heat is imported in this cavity, the internal gas expanded by heating, the pneumatic piston rod that promotes this cavity moves a section laterally and moves, because the movement of piston rod center of gravity, make the amount of unbalance of this side increase, reach with this and eliminate the unbalanced purpose of rotor-support-foundation system; Can also promote pneumatic piston rod (or interior survey) movement laterally of a plurality of cavitys by opening a plurality of air valves 4 and infrared source 9 simultaneously, adjust amount of unbalance, reach accurate adjustment and eliminate unbalanced purpose; In addition, a plurality of these automatic balancing arrangements can be installed on the unbalanced rotor in the time of necessary, reach the effect of better elimination rotor unbalance, make system balancing reach the optimum state.
Hollow shaft part 1 can be 1 with the cavity that bearing (ball) cover 5 forms, also can be for a plurality of, the invention provides a kind of rotor-support-foundation system automatic balancing arrangement of thermal radiation control of four cavity configurations, that is: hollow shaft part 1 is four groups with the cavity that bearing (ball) cover 5 sealings form, the pneumatic piston 2 that communicates with cavity also is four groups, axis is arranged in a crossed manner, and this spline structure is the simplest, compact, is convenient to be fixed on the unbalanced rotor.
Below in conjunction with Figure of description, by embodiment the present invention is described further:
Motion principle schematic representation 3 has illustrated the motion principle of this device, analyze unitary construction Fig. 1 and side view 2, in Fig. 1 and Fig. 2, unbalanced rotor is placed in the hollow shaft part 1, when detecting in the rotor motion process, sensor takes place when uneven, because the end of control air valve 4 is communicated with cavity automatically, air valve 4 can oppositely increase the pressure of corresponding cavity; Meanwhile, by control infrared source 9 emission heat energy, the surface scribbles the end cap window 7 that absorbs heat energy material 10 and absorbs heat energy, and heat energy imported in the cavity, acting that when gases are heated, they expand in the cavity, it is mobile laterally to promote pneumatic piston 2, and then makes the amount of unbalance of this side increase, and reaches with this and eliminates the unbalanced purpose of rotor-support-foundation system.Use small-sized sealing circle 3 to prevent that when gas promotes the piston motion in the cavity gas taking place leaks.
Among Fig. 4, scribble 4 local locations that absorb heat energy material 10 on the end cap window 7 of apparatus of the present invention, difference called after a, b, c, d represents this cavity and directly goes up different height, infrared source 9 is regulated its position that moves up and down automatically by the control of stepper motor 8, so radiant light can shine on the end cap window 7 by highly corresponding hole accordingly.Because rotor is to rotate continuously in the course of the work, therefore just can realize the needs cavity is added heat control by the height of control infrared source 9.
Shown in Figure 5 is the rotation A-A cut-away view of whole device, carries out the tightness protection by another seal ring 6 between shaft part end cap 5 and the cavity, with the airtight precision that guarantees that having of this device is very high.
Because therefore uniform four pistons of this device can also open a plurality of air valves 4 and infrared source 9 simultaneously, the pneumatic piston rod that promotes a plurality of cavitys (or interior survey) laterally is mobile, adjusts amount of unbalance, reaches accurate adjustment and eliminates unbalanced purpose.
In addition, a plurality of these automatic balancing arrangements can be installed on the unbalanced rotor in the time of necessary, reach the effect of better elimination rotor unbalance, make system balancing reach the optimum state.
