Abstract
The invention is an online automatic balanced head for dynamic balance under the condition that a rotary machine does not stop. The invention is composed of 1, a hub; 2, a slide bar; 3, a lead screw; 4, a slide block; 5, a gear set; 6, a motor; 7, a radio signal receiving device; 8, an inner hub; and 9, an installation joint. When a rotor produces unbalance dynamic due to high-speed rotation, a balancing apparatus measures the amount of unbalance and the corresponding phase position; according to measured amount of unbalance and the corresponding phase position, the radio signal receiving device 7 controls the motor 6 to rotate so as to rotate the lead screw 3 by the gear set; the slide block 4 of the inner screw thread rotates radially along the double slide bar 2 driven by the rotating lead screw 3 so as to accomplish reallocation of mass of the rotor, which accomplishes the online balancing of the rotor.
Description
The A technical field:
The invention belongs to on-line dynamic balancing equipment, be used for rotating machinery and under non-stop-machine situation, carry out transient equilibrium.After this device is installed, make rotor under non-stop-machine situation, adjusting mass distribution, thereby realizing transient equilibrium.
The B background technology:
Rotating machinery is used very extensive in actual production.In the fault of rotating machinery, have more than 60% all because rotor unbalance causes that therefore, the balance of assurance rotor is just very necessary.The balance method that adopts is mainly and uses equilibrator and spot dynamic balance at present.
The equilibrium strategy that is adopted mostly is: method of model balancing and influence coefficient method.But the process that no matter be to use equilibrator or spot dynamic balance, all needs to shut down, add test mass, start, shuts down, changes test mass again, starts shooting again.For the machinery of want balance, also be a kind of loss.Especially for being corrosive or the working medium of viscosity, the variation of randomness can appear in the mass distribution of rotor in rotary course.As the centrifugal blower in the dust pelletizing system, because the laying dust that is bonded on the impeller comes off, can cause the imbalance of blower fan system, thereby Oscillation Amplitude strengthens, for the safety of system, just have to shut down and carry out deashing.Behind deashing, variation has taken place in the mass distribution of vane rotor, must carry out transient equilibrium again.Have a strong impact on the continuous operations of enterprise.
So, realize that online moving transient equilibrium is optimal situation.Under this hope, many kinds of balance devices are suggested.Representative has: laser goes heavy formula; Electromagnetic type; Liquid-spraying type; Mechanical type.
These online balanced measures are because limitation separately can only be used for carrying out under the lower rotating speed transient equilibrium.So far there is not a kind of more perfect online dynamic equilibrium head to come into operation yet.Particularly mechanical type owing to complex structure, at high centrifugal force after the match, has the mobile difficulty more that becomes of the moving part of counterbalance weight, and it is bigger to wear and tear.The motor of employed driving and balance slide block locking mechanism performance are difficult to guarantee.The present invention designs at these problems.
The C summary of the invention:
The present invention is a kind of on-line dynamic balancing head.It is made up of 8 main parts.It is set for butt joint is installed that seam 9 is installed.
Balancing head is divided into two symmetric parts up and down.Have 6 groups of slide block mechanisms of symmetry in twos.The slide block quality is bigger, and wheel hub and interior wheel are all done relatively lightlyer.Total system is thin as far as possible, makes to try one's best rotor when installing.
For preventing that dust from entering, every group of slide block mechanism all has cover plate, and lubricating structure is also arranged.
The balancing head diameter needn't be done greatly as root diameter.
The power supply of system depends on the circumstances, can be by fair battery or magnetic strength motor provide repeatedly.
Between motor and the screw mandrel by the gear set transmission.Use bi-motor,, also increased safety coefficient for balance.Slide bar is the location for slide block, and screw mandrel plays transmission and locking action.
Use communicating wireless signals between the system and the external world.
The D description of drawings:
The structure of this balancing head is seen accompanying drawing 1: by 1 wheel hub; 2 slide bars; 2 screw mandrels; 4 slide blocks; 5 gear sets; 6 motors; 7 wireless signal receiving traps; 8 inner wheel hubs; 9 install seam forms.
The E embodiment:
According to formula m
1e
1ω=m
2e
2ω estimates the required balancing head of using.Balancing head is made series, provides convenience for selecting for use, installing.
The installation method of balancing head mainly contains two kinds:
(1) is directly installed on the armature spindle;
(2) being close to rotor by modes such as welding, bonding, bolts installs.
Suitable equilibristat is installed on rotor.
In system's operational process, equilibristat carries out on-line monitoring to rotor, notes the motion state of rotor.When imbalance took place rotor-support-foundation system, equilibristat was noted corresponding amplitude, phase place and frequency.Through corresponding analysis, give motor 6 running orders continuously by the wireless signal receiving trap.In this process, if find poor effect, all right repetitive operation does not have damage to former rotor.
This balancing head can be tackled the unbalance dynamic that occurs at random.To flexible rotor, can use a plurality of balancing heads to be used at a plurality of balanced surfaces.
The sharpest edges of this balancing head are exactly not shut down the continuous transient equilibrium that realizes rotor-support-foundation system.The total system reliable in structure, easy for installation, security system is high, easy to operate.Particularly for large rotor, counterbalance effect is better.
Claims (3)
1. an on-line automatic balancing head is used for carrying out transient equilibrium under not shutdown of the rotating machinery situation.The present invention is by 1 wheel hub; 2 slide bars; 3 screw mandrels; 4 slide blocks; 5 gear sets; 6 motors; 7 wireless signal receiving traps; 8 inner wheel hubs; 9 install seam forms.
2. this balancing head is to rotate by wireless signal receiving trap 7 control motors 6.Thereby rotate by gear set drive screw mandrel 3.The rotation of screw mandrel 3 drives female slide block 4 along two slide bar 2 radial motions, thereby realizes the rotor quality redistribution.
3. this device needs the configuration dynamic balance instrument, measures amount of unbalance and respective phase angle.Use motor respectively every group of slide block to be carried out continuous drive.
