Description
Technical field
The present invention relates to wind-driven generator, be specially a kind of transmission system of wind-driven generator.
Background technique
Wind-driven generator is the dynamic power machine that wind energy is converted to mechanical energy, existing wind-driven generator comprises directly driving type blower fan and common blower fan, its transmission system comprises the bearing support that is installed on the engine room foundation, be fixed with the bearing that is used for supports main shaft on the bearing support, one end of main shaft is fixed with the wheel hub that has brake disc, blade is housed on the wheel hub, the other end of the main shaft of directly driving type blower fan be connected with engine room foundation fixing directly drive generator, the other end of the main shaft of common blower fan is connected with main speed increaser and main speed increaser is installed on the engine room foundation the common generator that the output terminal of main speed increaser is connected with and engine room foundation is fixing by torque arm is unsteady.The working principle of the transmission system of wind-driven generator is to utilize wind-force to drive the blade rotation, thereby drive wheel hub and main shaft are rotated, and the common generator that directly drives generator or connect indirectly that the main shaft the other end connects carries out work under main shaft drives; Most parts all connect with engine room foundation in the transmission system of wind-driven generator, and main shaft not only bears flexural load but also bears torque load, this structural design causes that transmission system exists that maintenance difficulty is big, Heavy Weight, distortion is big and flimsy problem, in order to overcome this type of problem, people carry out various improvement to the transmission system of wind-driven generator, but still can not fundamentally address the above problem.
Summary of the invention
The present invention for the transmission system that solves existing wind-driven generator because unreasonable structure causes that maintenance difficulty is big, Heavy Weight, distortion is big and flimsy problem, and a kind of transmission system of wind-driven generator of stable performance is provided.
The present invention adopts following technological scheme to realize: the transmission system of wind-driven generator, comprise the drive sleeve that is fixed on the engine room foundation, be with at least one cover wheel hub bearing on the one side outer wall of drive sleeve, be with the wheel hub of band brake on the hub bearing external cylindrical surface, blade is housed on the wheel hub, the opposite side of drive sleeve is fixed with in driving mechanism and the drive sleeve and is provided with floating axle, and the two ends of floating axle are connected with driving mechanism with wheel hub respectively.Driving mechanism of the present invention is an existing structure, has the various deformation structure, realizes for those skilled in the art are easy.During work, wind-force drives the blade rotation, thereby driving wheel hub and floating axle is rotated, the driving mechanism that is connected with floating axle is worked under the drive of floating axle, in this process, owing to do not bear flexural load on the floating axle, only be used for bearing torque load, and drive sleeve only is used for bearing the flexural load of wheel hub, driving mechanism, does not bear torque load, thereby has avoided the transmission system maintenance difficulty of existing wind-driven generator big, Heavy Weight, distortion is big and flimsy problem.
Driving mechanism is for directly driving generator, directly drive the stator and the drive sleeve of generator and pass through bearing fixing, the rotor that directly drives generator by bearings on drive sleeve, the rotor that directly drives generator is connected with floating axle one end, the straight like this rotor of generator that drives is because the effect realization rotation of floating axle, thereby finish power generation operation, and reliable in structure, be not easy to damage.
Driving mechanism is made up of with the common generator that main speed increaser output terminal is connected with its input end the main speed increaser that its input end is connected with floating axle one end, the stator of common generator is fixed on the engine room foundation, the body of main speed increaser is fixed on the drive sleeve, when rotating, floating axle rotating speed is enlarged by main speed increaser, and then realize the generating requirement of common generator, and main speed increaser and drive sleeve rigid joint, solved the unsteady big problem of distortion of installing of main speed increaser.
The present invention improves by the transmission system to original wind-driven generator, make drive sleeve and floating axle bear flexural load and torque load respectively, and main speed increaser and drive sleeve rigid joint, not only has advantage easy to maintenance, in light weight, that intensity is high and rate of fault is low, and has an advantage easy for installation, that cost is low, transmission performance has also obtained good improvement simultaneously, satisfies the usage requirement of the blower fan of existing different capacity grade.
