Description
Technical field
The present invention relates to mechanical seal field, more particularly to a kind of seal for liquid compound spring.The present invention
Further relate to a kind of liquid compound spring for including this seal.
Background technology
In recent years, people's active development clean energy resource, wherein wind energy are a kind of new energy for cleaning and continuing forever.With to wind energy
Continually develop, wind generating technology has obtained development at full speed.With the continuous development of MW class wind turbine group, blower fan
Load it is increasing.Therefore, the damping to the key components and parts of generating set is also particularly important.
The supporting way of wind-driven generator group wheel box of the prior art mainly uses hydraulic pressure support.Hydraulic pressure support is main
It is a kind of novel damping support to grow up on traditional elastic brace foundation for four-point supporting type.Hydraulic pressure support is pacified
Mounted in the left and right sides of the gear-box of wind power generating set, per each one of side, the torsional load of gear-box is primarily subjected to, is mainly held
Load part is liquid compound spring.Wherein, the liquid compound spring of lower end and the compound bullet of liquid of right side upper end on the left of gear-box
Spring is connected by high-pressure hose, and the liquid compound spring of left side upper end and the liquid compound spring of right side lower end are soft also by high pressure
Pipe connects.The hydraulic pressure support of this structure is when bearing torsional load, because the two pieces elastomer of pressure-bearing is connected by high-pressure hose
Logical, liquid is not flowable, shows as very big torsional rigidity.And when bearing vertical load, the compound bullet of liquid of two pieces lower end
The liquid of spring intracavitary flow to the liquid compound spring intracavitary of upper end by high-pressure hose, shows as the vertical stiffness of very little and larger
Damping.
After liquid compound spring installation, its build-in cavities need to be vacuumized and topping up, after topping up, it is necessary to liquid
Bluk recombination spring is sealed.Hydraulic support system is very high to sealing requirements, therefore, to the Seal Design of liquid compound spring

So, the free end in lip portion 231 is arranged to the projection 232 that cross sectional shape is triangle.The projection 232 of the triangle is formed as
The isosceles triangle of line centered on the radial centre lines in lip portion 231, and the base of isosceles triangle is in lip portion 231
Radial outer end, and perpendicular to substrate 221.Equally, the drift angle of the isosceles triangle is in 60 degree to 150 degree of model before pressing
In enclosing, and after pressing in the range of 30 to 120 degree.Similarly, steel can be also embedded with isosceles triangle region
Circle 280, in the illustrated embodiment, the cross sectional shape of steel ring 280 is arranged to substantially isosceles trapezoid, and the upper bottom edge of the isosceles trapezoid
On the outside of on the inside of being radially oriented and bottom is radially oriented.So, after pressing, pressing plate 221 is with lip portion 231 in projection 232
Radially inner side forms the first seal point 250, and this structure can equally realize effective sealing to liquid containing chamber 113.
In addition, in the present embodiment, as shown in fig. 6, being equipped with ring in the bottom of substrate 221 and the neck 225 of pressing plate 222
Shape seam 227, the cross sectional shape of ring-type seam 227 for example set in the arc-shaped.Meanwhile the end of the projection 232 in lip portion 231
End is provided with fillet.Preferably, the radius of corner of raised 232 ends is more than the radius of corner of ring-type seam 227.So, pressing
When installing compressive resilience film 230, lip portion 231 can be pressed sufficiently in ring-type seam 227 due to compression, so as to
Ensure being brought into close contact between pressing plate 222 and substrate 221.
As shown in fig. 7, in one embodiment, the section setting of the projection 332 in lip portion 331 is in the arc-shaped.Meanwhile
The section for the steel ring 380 being arranged on inside projection 332 is arranged to the circle being adapted with the section of projection 332.The circle it is straight
Footpath size is preferably chosen as the opening size for being more than pressing plate 322 with being formed after the installation pressing of substrate 321, further to improve
The anti-pulling-and-doffing performance energy in lip portion 331.After pressing, pressing plate 321 forms first with lip portion 331 in the radially inner side of projection 332
Seal point 350, the second seal point 360 is formed in the radial outside of projection 332, so as to realize to the effective of liquid containing chamber 113
Sealing.
In a unshowned embodiment, lip portion 331 can be provided with multiple raised 332, and in each raised 332 area
Steel ring 380 is equipped with domain.On the one hand this structure adds the quantity of seal point, on the other hand also improve lip portion 331
Rigidity, be added significantly to the anti-pull-off performance of compressive resilience film 330.
As shown in figure 8, in one embodiment, the section setting of the projection 432 in lip portion 431 is rectangular.This
In the case of, the section for the steel ring 480 being arranged on inside projection 432 is arranged to the rectangle being adapted with the section of projection 432, the square
The long side of shape is placed perpendicular to lip portion 431 in the radial direction, and the long edge size of the rectangle is preferably chosen as being more than
Pressing plate 422 and the opening size formed after the installation pressing of substrate 421, further to improve the anti-pulling-and-doffing performance energy in lip portion 431.
After pressing, pressing plate 421 forms the first seal point 450 with lip portion 431 in the radially inner side of projection 432, in the footpath of projection 432
The second seal point 460 is formed laterally, so as to realize effective sealing to liquid containing chamber 113.
