Mode of execution:
Main design of the present utility model is: this device is arranged on 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 arranged on respectively in the cavity of the four hollow shaft parts 1 in chamber, end cap window 7 is arranged on bearing (ball) cover 5, bearing (ball) cover 5 is arranged on respectively hollow shaft part 1 two ends, shaft part is fastened on unbalanced rotor by sleeve, above-mentioned good air-proof condition is installed.When a certain side of determining rotor is uneven, detect the amount of unbalance information such as uneven direction, quality and phase place by sensor, determine the load balance condition, automatic control air-valve 4 increases the pressure of reverse cavity, and when the rotor 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 laterally a section and moves, movement due to the 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 be by opening simultaneously a plurality of air valves 4 and infrared source 9, the pneumatic piston rod of a plurality of cavitys of promotion (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 arranged on 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 rotor-support-foundation system automatic balancing arrangement that the utility model provides a kind of thermal radiation of four cavity configurations to control, 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 is also four groups, Axis Cross arranges, and this spline structure is the simplest, compact, is convenient to be fixed on unbalanced rotor.
Below in conjunction with Figure of description, by embodiment, the utility model is described further:
Motion principle schematic diagram 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 hollow shaft part 1, when detecting in the rotor motion process, sensor occurs when uneven, because the end of automatic control air-valve 4 is communicated with cavity, air valve 4 can oppositely increase the pressure of corresponding cavitys; Meanwhile, by controlling 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 is imported in cavity, acting that in cavity, when gases are heated, they expand, promote pneumatic piston 2 and move laterally, and then make the amount of unbalance of this side increase, reach with this and eliminate the unbalanced purpose of rotor-support-foundation system.Leakage Gas occurs when using small-sized sealing circle 3 to prevent the interior gas push piston movement of cavity.
In Fig. 4, scribble 4 local locations that absorb heat energy material 10 on the end cap window 7 of the utility model device, difference called after a, b, c, d represents different height on this cavity footpath, 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 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 controlling 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 cavity, with the airtight precision that guarantees that having of this device is very high.
Due to uniform four pistons of this device, therefore can also open simultaneously a plurality of air valves 4 and infrared source 9, 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 arranged on unbalanced rotor in the time of necessary, reach the effect of better elimination rotor unbalance, make system balancing reach the optimum state.
