Abstract
The invention provides a double-blade wind energy transmission mechanism which is characterized in that a main bevel gear is arranged on an output shaft and is in right-angled meshing with a small bevel gear and a large bevel gear, the inner bore of the small bevel gear is connected with the outer ring of a one-way bearing by virtue of an outer shaft pin, the inner ring of the one-way bearing is connected with a first input shaft by virtue of an inner shaft pin, one end of the first input shaft is connected with an inverted blade, the large bevel gear is connected with a second input shaft, a forward blade is arranged at one end of the second input shaft, similarly the one-way bearing can also be arranged on the second input shaft, and the outer ring of the one-way bearing is connected with the large bevel gear.
Description
Technical field
The present invention relates to a kind of wind energy driving mechanism, particularly a kind of double-fan-blade wind energy driving mechanism.
Background technique
Utilizing wind energy as mechanical kinetic energy, is the inexhaustible a kind of green power source of nature, but utilizes the collect folk songs mechanism fan blade of wind energy transformation for mechanical kinetic energy at present both at home and abroad; All adopt single group fan blade to collect folk songs to be converted into mechanical kinetic energy to wind energy and drive generator work; The blade type structure wind energy driving mechanism that this single group is collected folk songs, fan blade and the installation of generator right angle, directly driving generator by fan blade, to make wind energy transformation be kinetic energy; It is electric energy that normally this fan blade installation form of large-scale wind energy generator is accomplished wind energy transformation; But thisly directly be connected wind energy generating plant with generator, when generator power reaches MW class, when being installed in up to a hundred meters height to tens tons generator and the fan blade of weighing by fan blade; Installation difficulty and technical requirements are well imagined; MW class wind energy power exploitation and technology are controlled by some external major companies, made domestic wind-powered electricity generation enterprise be in technical passive position, and single group fan blade is collected folk songs, and to convert the utilization ratio of mechanical kinetic energy wind to not high for wind energy.
Summary of the invention
Technical problem to be solved by this invention for this reason is, overcomes existing technology and exists defective to provide a kind of simple in structure, and light a kind of double-fan-blade wind energy driving mechanism is installed, and makes wind energy reach higher utilization ratio.
Make the higher purpose of Wind Power Utilization in order to reach two fan blade transmissions, the technological scheme that the present invention adopts is: a kind of double-fan-blade wind energy driving mechanism comprises output shaft, master bevel gear; Reverse fan blade, bevel pinion, unilateral bearing; Clockwise fan blade, large bevel gear, its invention has following characteristic; Master bevel gear is housed above the output shaft, master bevel gear and the engagement of bevel pinion large bevel gear right angle, the endoporus of small bevel gear is connected with the unilateral bearing outer ring through outer pivot pin; The inner ring of unilateral bearing is connected with first input shaft through interior pivot pin, and an end of first input shaft is connected with the reverse fan blade, and large bevel gear is connected with second input shaft; One end of second input shaft is equipped with clockwise fan blade, and same unilateral bearing also can be installed in above second input shaft, and the outer ring of unilateral bearing connects with large bevel gear.
Working principle of the present invention is such: when low naturally wind speed blowed to clockwise fan blade, the moment that clockwise fan blade produced was directly passed through the transmission of the coaxial connection large bevel gear of second input shaft, meshed through large bevel gear and main shaft umbrella gear and drove output shaft; Because the other end of output shaft can be connected with generator or other load equipment, because of the load existence and the wind speed of generator or other load equipment are too low, and large bevel gear equates with the identical number of teeth of master bevel gear size; The moment that clockwise fan blade is transferred to above the output shaft is too little; At this moment clockwise fan blade is difficult to starting and rotates, but the present invention has installed the reverse fan blade at the homoaxial the other end of clockwise fan blade, is that the low wind speed of nature blows to when reversing fan blade equally; Unilateral bearing has been installed because of reversing the fan blade input shaft above coaxial; Bevel pinion is equipped with in the outer ring of unilateral bearing, and the diameter of bevel pinion is littler than main shaft umbrella gear diameter, and the bevel pinion gear ratio master bevel gear number of teeth is few; The same right angle engagement of bevel pinion and master bevel gear; Therefore bevel pinion produces speed ratio with master bevel gear and has alleviated reverse fan blade moment of rotation, make reverse fan blade can be under the effect of the wind-force of low wind speed quick rotation, drive the large bevel gear that meshes at the master bevel gear right angle and rotate simultaneously; Make clockwise fan blade drive generator or other load rotation work jointly, make wind energy reach again big utilization with reversing fan blade.
