Description
Technical field
The present invention relates to transient equilibrium checkout equipment technical field, relate in particular to a kind of high-speed horizontal dynamic balancing machine that has damping and revise thin and long units amount of deflection function.
Background technology
Horizontal dynamic balancing machine in usefulness is hard support dynamic balancing machine at present, and its support is the elastic body that is designed to small bore, and support is fixed on the fuselage, and fuselage is fixed on the built-in fitting of ground, and total system does not have shock attenuation device.Therefore, very low to the restriction of system rotating speed, the part that general balance is about 900 kilograms is hard to support horizontal dynamic balancing machine, and rated speed is at 1500 rev/mins.For the good part of rigidity, transient equilibrium under the working speed can be lower than.Be not good thin and long units for rigidity, the transient equilibrium under the low speed can not be satisfied the request for utilization under the working speed far away., run up down and do not have the elastic support of the fuselage of shock attenuation device and small bore can face the danger of judder.For example in recent years, the fast development of horizontal screw centrifuge required big rotary drum of length-diameter ratio and screw feeder to work down at 3000-4000 rev/min, and the rated speed that supports horizontal dynamic balancing machine firmly can not satisfy the horizontal screw centrifuge request for utilization far away.
Summary of the invention
The present invention provides a kind of a kind of high-speed horizontal dynamic balancing machine that has damping and revise thin and long units amount of deflection function in order to solve the problems of the technologies described above.
In order to overcome the defective of above-mentioned prior art, the invention discloses a kind of high-speed horizontal dynamic balancing machine, a kind of high-speed horizontal dynamic balancing machine comprises that the plane is down two groups of rigid supports, fuselage, transmission shaft and motors of T-shape; Each rigid support is provided with bearing, and two groups of rigid supports lay respectively at the both sides of fuselage, and balanced part is installed between two groups of rigid supports.
One side of said rigid support is provided with vibration transducer, and the other end is provided with motor, and the output terminal of motor is provided with phase disk, and the top of phase disk is provided with photoelectric sensor, and balanced part is dragged by motor through transmission shaft.
Said vibration transducer, photoelectric sensor are connected with the transient equilibrium computing machine through operation circuit.
Described fuselage base is provided with four rubber absorbers, and rubber shock absorber is connected with ground through built-in fitting.
In rotation, because part is laid particular stress on the vibration that causes, record and the passive equilibrium computer recording through vibration transducer, the phase place that maximum vibration took place and the rotating speed of part record and the passive equilibrium computer recording through phase disk and photoelectric sensor; The transient equilibrium computing machine adopts the calculation procedure of test mass method, calculates the phase angle of laying particular stress on and the quality that cause vibration; Through increasing the weight of or go heavily to realize the dynamic balance check of part.
The present invention has designed the support of heavy in section perfect rigidity, can not be damaged because of the vibration at a high speed; High speed rotating between fuselage and terrace, designed rubber absorbers, even if also can not cause fierce vibration and the damage parts; For avoiding vibroshock to give the influence of dynamically balanced precision, adopted the transient equilibrium program of test mass method; Simultaneously, also adopt the 3rd the high-speed balancing correction axis amount of deflection of thin and long units.The high speed of thin and long units, high-precision transient equilibrium like this, have just been realized.Especially condition has been created in the even running that is the high speed horizontal screw centrifuge of big L/D ratio.
