Technical field
The utility model relates to a kind of main parts size of wind power generating set, and particularly a kind of employing is in light weight, compact structure, the wind power generating set antivibration main machine base of optimized Structure Design such as load capacity is big, and stress concentration sensitivity is low.It is applicable to 1.5 megawatt dual-feed asynchronous wind power generators.
Background technique
As everyone knows, main machine base is one of core part of wind power generating set, and it is a main load bearing element, can bear from the moment of flexure of whole six directions of wind wheel and the impact of axial force, also be stressed the most complicated in the wind power generating set, processing cooperates the highest key components and parts of requirement.At present, the main machine base load capacity is big, makes processed complex, in the region of stress concentration under the limited conditions, is prone to material plastic deformation and destruction, and the fatigue ruption under random load.For addressing the above problem, existing report in some relevant patent documentations, as the patent No. is CN200920246659.X " wind power generating set mainframe ", disclose is material and the mainframe that corresponding attachment face is set with the nodular cast iron, has the good advantage of easy processing and resistance to shock, but because of it adopts main shaft bearing built-in, so there is installation and maintenance inconvenience problem.As China Patent No. is that " mainframe of horizontal axis wind-driven generator group " of 200920172803.X discloses a kind of mainframe that adopts the carbon structure steel profile to make, the bearing support of its spindle support shaft and pylon ducon axle interconnects by gap bridge, overcome the spindle support shaft that exists in the prior art stressed bad, with problem such as cast-steel chock weld strength susceptible to, but limit by structure, its resistance to shock is relatively poor, therefore haves much room for improvement.
The model utility content
The purpose of this utility model provides a kind of wind power generating set antivibration main machine base, it solved exist in the prior art in the region of stress concentration under the limited conditions, be prone to problems such as material plastic deformation and destruction, it is except that keeping the advantage that existing main machine base is processed easily and resistance to shock is good, it also has reasonable in design, stress distribution optimization, and is in light weight, bearing capacity is strong, stress concentration sensitivity is low, the antivibration good effectiveness.
The technological scheme that the utility model adopted is: this wind power generating set antivibration main machine base comprises with the nodular cast iron to be the pedestal cast of material and spindle bearing holder attachment face on the pedestal is set, gear-box base attachment face, generator base attachment face, the Yaw gearbox attachment face, cabin supporting base attachment face, driftage bearing ring gear attachment face and off-course brake attachment face, its technological points is: adopt air foil to be connected between the passenger cabin afterbody of described pedestal and the two side, between the two side of the passenger cabin inner chamber of described pedestal stiffening rib is set, and be positioned at over against the symmetrical middle position of described driftage bearing ring gear attachment face and off-course brake attachment face, described bearing support attachment face and gear-box base attachment face are in the same plane, and the elevation angle of avoiding vane tip and tower collision is set, the off-load equalizing orifice that reduces stress concentration sensitivity is set on the described pedestal wall.
Advantage and the good effect that the utlity model has are: owing to still adopt with the nodular cast iron is the pedestal that material is cast, so keep existing main machine base processing and the good advantage of resistance to shock easily.In addition, because of adopting method that theoretical algorithm combines with finite element analysis that structures such as gusset shape, position, thickness and sidewall shape, position, thickness and the position of opening of pedestal and shape are optimized design, so be connected with air foil between the passenger cabin afterbody that makes pedestal and the two side, concentrate with the resistance and the stress that reduce wind; In the passenger cabin of pedestal stiffening rib is set, and is positioned at, increase the bearing capacity of main machine base over against the symmetrical middle position of driftage bearing ring gear attachment face and off-course brake attachment face; On the also present body wall off-load equalizing orifice that reduces stress concentration sensitivity is set, above measure is reasonable in design not only, and is in light weight, bearing capacity is strong, and can realize reasonable distribution product weight and safety coefficient, antivibration is effective, and stress distribution optimization reduces stress concentration sensitivity.Its bearing support attachment face and gear-box base attachment face are in the same plane, and casting technique is simple, is convenient to machining.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is a kind of concrete structure schematic representation of the present utility model.
Fig. 2 is the worm's eye view of Fig. 1.
Sequence number explanation among the figure: 1 spindle bearing holder attachment face, 2 gear-box base attachment faces, 3 generator base attachment faces, 4 Yaw gearbox attachment faces, 5 cabin supporting base attachment faces, 6 driftage bearing ring gear attachment faces, 7 off-course brake attachment faces, 8 pedestals.
