Raw overload phenomenon, causes generator life to shorten.
Summary of the invention
It is an object of the invention to provide a kind of for puna improvement High aititude wind power generating set transmission
Device, to solve the problem proposed in above-mentioned background technology, had the beneficial effect that blade uses
PE low-pressure polyethylene and multiple composite processing form and are suitable for puna so that service life of a machine increases
Adding, in transmission process, energy loss is less, improves the efficiency of wind-power electricity generation.
For achieving the above object, the present invention provides following technical scheme: a kind of for puna improvement height
Height above sea level transmission gear of wind generating set, including blade, step-up gear, electromotor, cabin, low speed
Axle and brake, described blade is arranged on vane change device, and vane change device is fixed on the left of slow-speed shaft,
Kuppe is installed outside described vane change device, described slow-speed shaft is provided with bearing, and bearing is fixed on
On bearing block, bearing block is fixing with cabin to be connected, and is provided with step-up gear, institute on the right side of described slow-speed shaft
Stating and be provided with rotating shaft on the right side of step-up gear, and rotating shaft is made up of high speed shaft and generator shaft, high speed shaft sets
Putting on the left of generator shaft, described step-up gear is fixed on the left of stand, is provided with on the right side of described stand
Being provided with adjusted device below electromotor, and stand, described adjusted device is fixed on pylon.
Preferably, it is provided with empennage on the right side of described cabin.
Preferably, described high speed shaft is rotationally connected by brake with generator shaft.
Preferably, below described high speed shaft, bearing is installed.
Preferably, it is provided with shaft coupling between described slow-speed shaft and step-up gear.
Compared with prior art, the invention has the beneficial effects as follows: this equipment wind wheel blade uses PE low pressure to gather
Ethylene and multiple composite processing form, be suitable for puna and simple in construction, quality less,
Mechanical property is higher, and what vane change device employing was ripe determines slurry structure, without complicated mobile machine device, exempts from dimension
Protecting, fault rate is extremely low, and the most applicable high and cold unmanned area, kuppe uses optimal aerodynamic to make
Windage relatively low water conservancy diversion effect is obvious, and the tail gear of simplification is outside the demand meeting extremely frigid zones wind-power electricity generation
The fault rate making this equipment reduces, and the actuating device of group of motors uses novel low temperature resistant steel, more resistance to
Low temperature, wear-resisting, add specific low temperature resistant grease in step-up gear, reduce the mill of pinion rotation
Damage, extend gear and use the time, reduce power transmission loss, at high speed shaft and the electromotor of actuating device
Brake it is provided with so that this wind-driven generator is relatively big, when blade rotational speed is too high in external wind between axle
Generator power will not be made too high.
