Description
Technical field
The present invention relates to a kind of dynamic balancing head that is used for the rotating machinery on-line dynamic balancing.
Background technique
Dynamic balancing technique occupies critical role in rotating machinery.Owing to reasons such as design, processing, transportation, installation, material behaviors, rotating machinery is easy to produce initial unbalance; Rotatable parts breakage in the running, peel off also and can cause bigger imbalance.Rotor unbalance will produce tangible power frequency vibration, influence the normal operation of rotating machinery.In case vibration exceeding the standard just need carry out dynamic balancing to rotor.At present, the dynamic balancing technique that comprises the high speed rotor of flexible rotor has developed very ripely.But the adjustment process repeatedly that the dynamic balancing process that is adopted is a test mass, increase the weight of requires start-stop car continually, spends more manpower, financial resources and time.On-line dynamic balancing is a good method of head it off.
General on-line dynamic balancing system mainly comprises two-part: a part is mounted in the dynamic balancing head that is balanced on the machine rotors, and another part is a controller.Controller comprises sensor and interlock circuit, driver, control software etc.With regard to state-of-the art, controller part is very ripe, and a large amount of work mainly concentrates on how to design simple in structure, a reliable and dynamic balancing head cheaply.
Mainly contain the dynamic balancing head of three kinds of main flows at present: motor-driven machinery dynamic balancing head, liquid-spraying type dynamic balancing head and electromagnetic type dynamic balancing head.In first kind of motor-driven machinery dynamic balancing head, two motors are arranged.Every motor connects counterweight by screw mandrel or gear separately.The driving power and the control signal of motor are transmitted by slip ring.Come mobile counterweight just can produce suitable correction mass by the control motor.In second, in the liquid-spraying type balancing head, four fan-shaped cavitys are arranged.Other has four nozzles, fan-shaped cavity of each nozzle alignment.Arrive suitable cavity by the liquid that sprays suitable quality, just can produce the correction mass of expection.In the third electromagnetic type balancing head, two or three sliding plates are arranged, counterweight is arranged on every sliding plate and can be under the effect of external force circumferentially rotate.External force is the electromagnetic force that electromagnetic coil energising back produces.Thereby the control electromagnetic force just can move on to sliding plate appointed positions and produce the correction mass of wishing.The use occasion of these three kinds of balancing heads is all restricted, generally all is used on the machine with stiffness rotor, and also restricted to the ambient temperature of using.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, reliable, Purely mechanical on-line dynamic balancing head that cost is low.
Purely mechanical on-line dynamic balancing head of the present invention, it is characterized in that comprising rotatable parts and static part two-part, rotatable parts are by two cover plates, four guide plates and three are clipped in the cylindrical body that two plate washers between guide plate repeatedly are set to one respectively, its cover plate has the identical center hole of diameter respectively with each plate washer, edge, plane at every plate washer circumferentially is evenly equipped with four holes, the center of every guide plate has eccentric circle, eccentric diameter of a circle is greater than the aperture of cover plate and plate washer center hole, edge, plane at every guide plate circumferentially is evenly equipped with four holes, eccentric circle is connected with one of them hole by guide slide, the last relatively successively guide plate of every guide plate in the rotatable parts cylindrical body clockwise rotates 90 degree, four holes of guide plate are communicated with four holes of plate washer respectively, form inner separate and circumferential four the uniform cavity volumes in edge of cylindrical body, static part is the inner core of being fitted and being nested with by coaxial line, middle tube and urceolus are formed, on middle tube, have four parallel helical slideways, on urceolus, have eight circular holes of two rows, wherein four circular holes of the row of going up are communicated with the upper end-hole of four parallel helical slideways respectively, arranging four circular holes down is connected with the lower end mouth of four parallel helical slideways respectively, one end of static part is fixed on the support, the other end stretches in the cylindrical center hole of rotatable parts and also and between center hole leaves the gap, insert four circular holes on the urceolus in the center hole respectively with repeatedly to put the eccentric guiding groove that forms by guide plate and baffle plate or cover plate corresponding, the cylindrical end face of rotatable parts is fixed with coupling disc, and coupling disc and rotating shaft are fastening.
In order to the storage steel ball, static part is fixed on the support along four circumferentially uniform cavity volumes that are mutually independent in on-line dynamic balancing head rotatable parts inside, is used for throwing steel ball to the different cavity volume of rotary component.In the running, driven by motor rotating shaft and the balancing head rotatable parts that are installed in the rotating shaft rotate, the circular hole of arranging on the static part urceolus adds steel ball, steel ball is in spiral slideway enters the different cavity volume of rotary component, by mass distribution from rotary component to the steel ball of different cavity volume filling varying numbers that can regulate, thereby realize on-line dynamic balancing.
On-line dynamic balancing head based on Design of Mechanical Structure of the present invention does not need to the rotating part power supply, and stability is quite high.This on-line dynamic balancing header structure is simple and the life-span is longer, and the steel ball size is optional, and each quality that increases the weight of is easily transferred, and makes dynamic balance accuracy control easily.This balancing head can be used for the high temperature occasion.
