Description
Technical field
The invention mainly relates to Helicopter Transmission System rear axle dynamic balancing technique more particularly to a kind of Helicopter Transmission Systems
Rear axle dynamic balance method.
Background technique
Advanced medium-sized multimission helicopter is a kind of civil helicopter in China and French co-production, the mark of the helicopter
Quasi- design take-off weight is 6 tons.Helicopter code name in the helicopter sequence of Ou Zhi company is EC175, in Chinese Helicopter
Code name is Z15 in sequence.
The axis is in good condition when product is delivered, and dynamic balancing is completed by PANKL company, is not produced at home, product former material
Material, product manufacturing and manufacturing technology rely on import.Equipped detection torque sensor is required in actual tests and work of taking a flight test, i.e.,
Installation torque sensor is needed at home, equipped with after torque sensor, new imbalance is caused, if rear axle has new injustice
Weighing apparatus will cause vibration and noise, reduce helicopter use reliability, cause rear axle and other component to wear aggravation, use the longevity
Life reduces, and even results in rear axle failure or generates serious consequence.So must dynamic balancing again at home, with satisfaction " tail transmission
Axis dynamic balancing program (TN M651E501E01) " final requirement for dynamic balance.It is this for Helicopter Transmission System rear axle dynamic balancing
It is required that existing equipment and process are difficult to realize for three plane removal surpluses.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of simple to operate, test
True dynamically balanced Helicopter Transmission System rear axle dynamic balance method precisely, under achievable multi-state multimode,
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of Helicopter Transmission System rear axle dynamic balance method, comprising the following steps:
S1: it determines balance weight position: clamping to form integral rotor using tooling and rear axle both ends, the integral rotor of formation is placed
On dynamic balancing machine, determine that two are gone to surplus section on integral rotor, starting dynamic balancing machine drives rotor rotation respectively 0
It is tested in degree, 120 degree and 240 degree of three phases, when rotor reaches setting revolving speed, shows screen display in test macro
The size and location of amount of unbalance is the size and location of rear axle residual unbalance,；
S2: it determines balance weight bonding region: the balance weight position that preamble determines being corresponded and is drawn on lead foil gummed paper, scissors is used
Lead foil gummed paper at balance weight is sheared off, remaining lead foil gummed paper is sticked on rear axle, what is formed after lead foil gummed paper bonding engraves
Empty region is balance weight bonding region；
S3: it is glued: balance weight is glued to the bonding region that preamble determines；
S4: it solidification: is carried out using fixture and clamps and solidify under normal temperature；
S5: bonding quality is examined: using ultrasonic inspection is carried out on ultrasonic inspection machine, gap is glued in detection, and degumming rate is not permitted
It perhaps is more than the 10% of glue surfaces, and balance weight surrounding is not allow for degumming phenomenon；
S6: fill spray priming paint and finishing coat for the first time: spraying one layer of bottom to other priming paint breakages on balance weight and part outer surface
Paint sprays a level paint to other finishing coat breakages on balance weight and part outer surface；
S7: final dynamic balancing: rear axle is mounted on dynamic balancing machine, is opened dynamic balancing machine and is carried out accurate dynamic balancing, if any a little
Uneven then be removed surplus, to guarantee that permissible residual unbalance is no more than 50g.mm, in the middle part of axis peak-peak displacement
Less than 1.00mm；
S8: fill spray priming paint and finishing coat for the second time: spraying one layer of bottom to other priming paint breakages on balance weight and part outer surface
Paint sprays a level paint to other finishing coat breakages on balance weight and part outer surface.
As a further improvement of the above technical scheme:
In step s 2, it needs to clean simultaneously the surface that is stuck of lead foil gummed paper before remaining lead foil gummed paper is sticked on rear axle
It is dried up with compressed air.
In step s 2, sanding need to be carried out to balance weight bonding region until exposing metal body, to sanding region
Clean and dried up with compressed air.
In step s3, it should ensure that 18 C < T <, 29 C, 40% < RH < 65%, T are temperature, and RH is relative humidity.
In step S6 and step S8, it should be dried at normal temperature after the finishing coat that fills spray, drying time is not small in small 5
When.
Compared with the prior art, the advantages of the present invention are as follows:
Helicopter Transmission System rear axle dynamic balance method of the invention, it is Promethean that three sections balance is reduced to two-section face balance
