Description
Technical field
The invention belongs to rotating machinery automatic balancing technology fields, are especially adapted for use in the autobalance of propeller, in real time
Carry out on-line vibration inhibition.
Background technique
Propeller rotates in air or water by blade and generates power, leads in current General Aviation and sea transport
Domain, propeller power device obtain relatively broad application, such as propeller with its good economy and higher propulsive efficiency
Aircraft, propeller of steamer etc..Propeller can be such that propeller is filling as high-speed rotary part, due to manufacturing, assembling equal error
It is inevitably generated mass center deviation after machine, or mass center caused by blade mass change in-flight deviates etc., can make spiral
Paddle generates unbalance vibration in high-speed rotation process.In actual use, the propeller vibration generated by mass unbalance is asked
Topic is more prominent, causes associated components to generate structural fatigue and destroys, and blade even occurs when serious and fractures accident, so must be right
Propeller carries out trim to reduce its vibration values level, and traditional Calculate Ways are to apply counterweight by shutting down, and can not achieve
Vibration suppression in propeller operational process.Therefore, how more convenient, effective realization propeller dynamic balancing is always engineering
Scientific and technological circle's problem urgently to be resolved.
Carry out research in terms of propeller autobalance both at home and abroad, it is specific as follows.
A kind of automatic balancing arrangement for aircraft live spindle has been invented by Hofmann company, Germany within 2012.Using tool
There are the solid or fluent material of thixotropic nature, using centrifugal force automatic adjusting position, is filled in one and revolves around it main shaft
In cavity.Reach autobalance by changing the position of thixotropic materials.The balance mode is a kind of passive type autobalance,
Implement there are strict requirements to thixotropic materials, to the rotation speed of aircraft main shaft during balancing.It is different from the present invention it
Being in: balance method used in the present invention is to drive the clump weight position in automatic balancing arrangement by interior excitation to reach dynamic flat
Weighing apparatus, belongs to active balancing device.
Lord company, the U.S. most disclosed earlier than 2008 and 2009 patent WO2008127362A3 and
US20090306829A1 proposes a kind of aero-engine propeller automatic-balancing system.The autobalance actuator is by wearing
Axis mode is arranged close to the inner side of blade.It is different from the present invention, the stationary ring of the automatic balancing arrangement is outside rotating ring
Side, i.e., outside along radial direction excitation mechanism, clump weight is in inside.When same weight mass, balanced capacity the present invention can provide
Bigger balanced capacity.The said firm proposed patent US20110197703A1 and WO2012051475A1 in 2012 again, original
Slip ring structure is increased on the basis of automatic balancing arrangement, is transmitted for data.EP2647567A2 and 2015 year 2013
US8961140B2 discloses a kind of interior excitation automatic balancing arrangement with slip ring structure.However, drawing due to slip ring structure
Enter, causing balancing device, structure is complicated, generates certain influence to the service life of complete machine.The present invention the difference is that: do not use
Slip ring carries out data transmission, and avoids slip ring abrasion bring hidden danger.
2014, domestic patent CN206654184U disclosed a kind of dynamically balanced paddle seat of adjustable folding formula propeller,
Function is adjusted in the center of gravity that can be realized propeller, but the patent belongs to offline dynamic balancing technique field, can not achieve online
Dynamic balancing.
2016, domestic patent CN205931235U disclosed a kind of amphibious aircraft with autobalance empennage,
Flight adjustment is carried out by the way that a tailplane is arranged in propeller, plays the role of smooth flight.With it is proposed by the invention
For mass unbalance vibration carry out autobalance, belong to different research objects and balance field.
2018, domestic patent CN106312821B proposed a kind of side exciting electromagnet sliding ring type automatic balancing arrangement, passed through
Change the real-time inhibition that unbalance vibration is realized in weight mass position.Its design feature is the placement of magnet exciting coil axial sides, but
The structure is not suitable for being applied to major diameter propeller dynamic balance field, and quality, volume are larger.
In short, automatic balancing arrangement involved in correlative study both at home and abroad is different from the present invention.
Summary of the invention
In order to overcome the problems, such as that existing outer excitation autobalance size is big, weight is big, balanced capacity is limited, the present invention is logical
It crosses built in electromagnetic drive copper coil, the external mode of clump weight, designs the mountable interior excitation in propeller paddle shaft of one kind certainly
