Description
Technical field
The present invention relates to a kind of blower fan gearbox and its draw bail of sun gear and gear wheel axle sleeve, particularly spline pair
Lubrication flushing mechanism.
Background technology
Blower fan gearbox is the precision gear transmission case that a kind of required precision is high, reliability requirement is high.It is wind-power electricity generation
An important mechanical part in unit, on the mainframe of fan engine room, for connecting wheel hub main shaft and generator, its
Main function is to pass to generator and it is obtained corresponding rotating speed the produced power under wind-force effect of wind wheel, is wind
Core apparatus in machine, it is necessary to safe and reliable, durable in use, service life typically requires to be 20 years.
Spline pair is frequently used in powerful transmission system as common draw bail.Spline pair has centering
High precision, axially directed property is good, can transmit larger main moment of torsion, the features such as installing/dismounting is easy.But can be deposited during spline subtask
In the big situation of fretting wear, caloric value, therefore the lubrication developing result of spline pair can to the life-span of spline pair and use
It is most important by property.
The sun gear and gear wheel axle sleeve of blower fan gearbox are typically coupled with spline pair.Load in view of planetary stage will
Ask, generally sun gear is designed to relocatable, which exasperates the fretting wear of spline pair, bring bigger caloric value.From
From the point of view of wind power plant practical operation situation, the secondary failure of spline connection accounts for significant proportion in gearbox fault, at present on the market
Blower fan gearbox also all consider lubricant passage way for sun gear and the connection of gear wheel axle sleeve spline pair, typically in sun gear and
Large Gear Shaft puts to process complicated oil-feed oil circuit and oil return circuit or increase disc and forms oil circuit, and with the two of spline pair
End face carries out axial limiting, but these scenario-frames are complicated, lubricates insufficient, and processing and manufacturing requires height, while can also influence too
The intensity of sun wheel and gear wheel axle sleeve, reduces the safety and reliability of spline pair connection.
In the Chinese invention patent of Publication No. CN103711885, there is provided a kind of blower fan gearbox sun gear and big
The lubricating and cooling method of gear bush spline pair connection.The upwind of spline pair carried out with pressing plate it is spacing, in pressing plate and sun gear
Between form one and enclose circumferential clearance oil-feed, it is spacing to wind direction under spline pair that gear wheel inner hole of shaft sleeve the inside devises boss, and big
Deep and long hole oil return is machined on gear bush.Although this design forms effective lubricant passage way, its oil-feed oil circuit because
It is to be limited by upwind bearing size, hollow core cable pipe size, thickness of compressive plate and sun gear intensity requirement, oil-feed space reality
It is very limited on border, it may not be possible to abundant oil-feed, it is that this oil-feed space is by sun gear is cylindrical and pressing plate endoporus the reason for specific
Collectively form, hollow core cable pipe be from sun gear endoporus pass through and hollow pipe outside dimension be overall design give, it is contemplated that
, so as to define the minimum dimension of sun gear external diameter, when the timing of brearing bore size one, oil-feed space is just for sun gear bearing requirements
It has been determined that increasing a baffle plate will sacrifice very big oil-feed space；Simultaneously with pressing plate and the upper leeward of the spacing spline pair of boss
Lubricant housings and lubricant effect are also limit to end face, the position lubricating oil that spline pair end face is blocked by pressing plate and boss circulates not
Smooth, as run time increases, abrasion increases, and influences also all the more obvious；With pressing plate and the upper leeward of the spacing spline pair of boss
During to end face, the length of interior external splines will be limited；On the one hand other Large Gear Shaft puts the oil return of processing deep and long hole can influence it
Intensity, particularly fatigue strength, on the other hand tiltedly the processing of deep and long hole is also very complicated.
