Background technique
Wheel hub is the vitals that connects blade and main shaft, and it has born wind-force and has acted on thrust, moment of torsion and moment of flexure on the blade.The effect of wheel hub is to transmit the power of wind wheel and moment in the mechanical structure of back, and the load on the blade can be delivered on cabin or the pylon thus.
At present, wheel hub steel plate commonly used is welded.The wheel hub of welding needs to proofread and correct after welding, work such as levelling, and weld seam must pass through ultrasonic examination, the production process complexity.The weld fatigue that the alternating stress that produces during the wheel hub rotation can cause.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of feather technology that is applicable to is provided, and damping property is good, and stress concentration sensitivity is low, and is rational in infrastructure, has the wheel hub of advantages of good abrasion and corrosion resistance characteristic.Can satisfy pitch variable bearings on it, become the oar driving, control system, lift the installation requirements of parts such as blade static pulley certainly.
A kind of wind-powered electricity generation unit wheel hub, this wheel hub is a Three way type spheroidal wheel hub, comprises the spheroidal hollow shell, and this shell is provided with the main shaft attachment face, the side of this shell is evenly distributed with three pitch variable bearings attachment faces along circumferential, and each pitch variable bearings attachment face correspondence is provided with a floor.
There is a non-vanishing angle between the running shaft of described pitch variable bearings attachment face and wheel hub.
The side of this shell also is evenly distributed with three static pulley fitting seats along circumferential.
Described each floor is provided with and becomes oar drive installation seat, position limit switch fitting seat, position transducer fitting seat, blade locking device fitting seat and spacing collision block one of them or its combination.
Circle distribution one circle blade installation hole along each floor.

Embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model wheel hub, and as shown in Figure 1, wind-powered electricity generation unit wheel hub of the present utility model is a Three way type spheroidal wheel hub, adopts ductile cast iron material to make, and good casting property, technology is easy and cost is low.This wheel hub comprises hollow spheroidal shell, is arranged with two manholes on the spheroidal shell.It is the running shaft of wheel hub that one of them manhole is provided with the line that is used for 1, two manhole of main shaft attachment face of being connected with main shaft.
Direction with this main shaft attachment face 1 is the below, then is evenly distributed with three circular holes in the side of spheroidal shell along circumferential, is equipped with pitch variable bearings attachment face 2 on three circular hole circumference.Pitch variable bearings attachment face 2 is not parallel with the wheel hub running shaft, but has a non-vanishing angle, can be blade cone angle is provided.Wheel hub provides the blade cone angle, not only can reduce tower shadow effect, and reduces the bending blade stress that centrifugal force causes under normal operating condition, and can prevent the chance of blade tip and tower collision.
Correspondingly with each pitch variable bearings attachment face 2 be provided with a floor 3, floor 3 is provided with and becomes oar drive installation seat 4, position limit switch fitting seat 5 and position transducer fitting seat 6, becomes oar driving, position limit switch and position transducer in order to install respectively.Also be provided with blade locking device fitting seat 7 on the floor 3, be used to install blade locking device, the limit blade rotation improved the Security that wheel hub lifts when blade locking device lifted in wheel hub; Spacing collision block 8 is used to guarantee that the blade feather position is accurate.Circle distribution one circle blade installation hole 9 along floor 3 is used to make things convenient for blade installation.
Be evenly distributed with three static pulley fitting seats 10 in the side of spheroidal shell along circumferential, be used for fixing, can reduce blade maintenance, replacement cost from lifting the static pulley that blade is used.Wheel hub inside is provided with control cabinet fitting seat 11, lubrication system fitting seat 12, wheel hub heat-exchanger rig fitting seat 13 and cable clip fitting seat 14, is respectively applied for installation and control cabinet, lubrication system, wheel hub heat-exchanger rig and cable clip.
Wind-powered electricity generation unit wheel hub of the present utility model is applicable to the feather technology, and damping property is good, and stress concentration sensitivity is low, and is rational in infrastructure, has advantages of good abrasion and corrosion resistance characteristic.Can satisfy pitch variable bearings on it, become the oar driving, control system, lift the installation requirements of parts such as blade static pulley certainly.And install, use simply, line service is few.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
