Background technique
The rotor of rotating machinery is because being subject to the impact such as quality of materials and processing technique, and epitrochanterian quality can not axisymmetric and there is bias utterly, forms periodically centrifugal force interference, make machine produce vibration, i.e. rotor unbalance when rotor rotates.Even if do strict dynamic balancing to each rotor part, and centering is installed well, but still stronger vibration may occurs during the system cloud gray model of composition.The solution adopted at present be both at home and abroad complete machine full speed dynamic balance to eliminate the imbalance of this rotor axial system, but the method needs repeatedly starting and stopping unit, not only schedule delays, also causes huge economic loss.
Summary of the invention
Uneven in order to overcome rotary machine rotor system, and make up the deficiency of current balancing technique, the invention provides a kind of automatic balancing arrangement, this device can eliminate the imbalance of rotary machine rotor system, and due to controlled thermal radiation, make this device Adjustment precision higher and easy to adjust, make balancing rotor system reach the optimum state.
The present invention is achieved through the following technical solutions:
A kind of rotor-support-foundation system automatic balancing arrangement adopting thermal radiation to control, it is characterized in that: this device is arranged on unbalanced rotor shaft shoulder position, the bearing (ball) cover that hollow shaft section and two ends are arranged seals the cavity forming middle part, hollow shaft section is provided with pneumatic piston and air valve, and pneumatic piston and air valve communicate with cavity; Bearing (ball) cover is provided with sleeve, for being connected with unbalanced rotor; Bearing (ball) cover is also provided with end cap window, end cap window local location scribbles and absorbs heat energy material; The position relative with end cap window is provided with infrared source, and the device be connected with infrared source is a stepper motor.
It is multiple for being arranged on and end cap window scribbles the local location absorbing heat energy material, arranges respectively with different heights.
It is four groups that hollow shaft section and bearing (ball) cover seal the cavity formed, and the pneumatic piston communicated with cavity is also four groups, and Axis Cross is arranged.
Advantage and effect: the invention has the beneficial effects as follows, this Equilibrator has automaticity, controllability, precision high, eliminates uneven Be very effective, and apparatus structure is simple, cost is low, greatly reduces the cost of balancing technique before this.

mode of execution:
Central scope of the present invention is: this device is arranged on unbalanced rotor shaft shoulder position.This device is scribbled the part such as end cap window 7, seal ring 3 and 6, sleeve, pneumatic piston 2, air valve 4, infrared source 9 absorbing heat energy material formed by hollow shaft section 1, bearing (ball) cover 5, surface, pneumatic piston 2 and air valve 4 are arranged in the cavity of four chamber hollow shaft section 1 respectively, end cap window 7 is arranged on bearing (ball) cover 5, bearing (ball) cover 5 is arranged on hollow shaft section 1 two ends respectively, shaft part is fixed in unbalanced rotor by sleeve connection, is above-mentionedly provided with good air-proof condition.When determining that certain side of rotor is uneven, the amount of unbalance information such as uneven direction, quality and phase place are detected by sensor, determine load balance condition, automatic control air-valve 4 increases the pressure of reverse cavity, and control infrared source 9 when the rotor rotates and heat this end cap window, heat is made to import in this cavity, internal gas expanded by heating, the pneumatic piston rod promoting this cavity moves a section laterally and moves, due to the movement of piston rod center of gravity, the amount of unbalance of this side is increased, reaches with this and eliminate the unbalanced object of rotor-support-foundation system; Can also by opening multiple air valve 4 and infrared source 9 simultaneously, promote (or the interior survey) movement laterally of the pneumatic piston rod of multiple cavity, adjustment amount of unbalance, reaches accurate adjustment and eliminates unbalanced object; In addition, can this automatic balancing arrangement multiple be arranged in unbalanced rotor time necessary, reach the effect better eliminating rotor unbalance, make system balancing reach the optimum state.
The cavity that hollow shaft section 1 and bearing (ball) cover 5 are formed can be 1, also can be multiple, the rotor-support-foundation system automatic balancing arrangement that the thermal radiation that the invention provides a kind of four cavity configurations controls, that is: hollow shaft section 1 and bearing (ball) cover 5 seal the cavity formed is four groups, the pneumatic piston 2 communicated with cavity is also four groups, Axis Cross is arranged, and this spline structure is the simplest, compact, is convenient to be fixed in unbalanced rotor.
Below in conjunction with Figure of description, by embodiment, the present invention is described further:
Motion principle schematic diagram 3 describes the motion principle of this device, analyze unitary construction Fig. 1 and side view 2, in fig. 1 and 2, unbalanced rotor is placed in hollow shaft section 1, when sensor detects that in rotor motion process, generation is uneven, due to end and the cavity connects of automatic control air-valve 4, air valve 4 oppositely can increase the pressure of corresponding cavity; Meanwhile, heat energy is launched by controlling infrared source 9, surface scribbles the end cap window 7 absorbing 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 to move laterally, and then the amount of unbalance of this side is increased, reach with this and eliminate the unbalanced object of rotor-support-foundation system.Small-sized sealing circle 3 is used to prevent from, during gas push piston movement in cavity, Leakage Gas occurs.
In Fig. 4, the end cap window 7 of apparatus of the present invention scribbles 4 local locations absorbing heat energy material 10, called after a respectively, b, c, d, represent height different on this cavity footpath, infrared source 9 regulates its position that moves up and down automatically by the control of stepper motor 8, and therefore radiant light can be irradiated on end cap window 7 by the hole corresponding to corresponding height.Because rotor is rotate continuously in the course of the work, the height therefore by controlling infrared source 9 just can realize carrying out computer heating control to needs cavity.
Shown in Fig. 5 is the rotation A-A cut-away view of whole device, carries out tightness protection between shaft part end cap 5 and cavity by another seal ring 6, has very high airtight precision with what ensure this device.
Due to uniform four pistons of this device, therefore can also open multiple air valve 4 and infrared source 9 simultaneously, promote the pneumatic piston rod of multiple cavity laterally (or interior survey) mobile, adjustment amount of unbalance, reaches accurate adjustment and eliminates unbalanced object.
In addition, can this automatic balancing arrangement multiple be arranged in unbalanced rotor time necessary, reach the effect better eliminating rotor unbalance, make system balancing reach the optimum state.
