Abstract
The utility model relates to a transmission chain device of a wind driven generator, which comprises a main shaft and a generator, wherein a gearbox is connected between the main shaft and the generator. The transmission chain device of the wind driven generator is characterized in that the front portion and the rear portion of the main shaft are respectively provided with a floating bearing and a thrust bearing, and the floating bearing and the thrust bearing are fixedly connected onto an engine room seat of a wind generating set through a bearing seat of the floating bearing and a bearing seat of the thrust bearing. The floating bearing bears overturning moment and radial force which are generated by rotation of a wind wheel, and the thrust bearing bears axial force and radial force which are caused by inclination of the wind wheel. The transmission chain device of the wind driven generator greatly improves stress condition of the gearbox and basically eliminates influence on the gearbox from external loads. The reliability of the gear box is greatly improved, parts are convenient to mount, and the operational space is large. During large maintenance work of the gearbox, no tailor-made tooling is needed to stabilize the wind energy, thereby being convenient to maintain.
Description
Technical field
The utility model relates to the Transmitted chains device of a kind of transmission device of wind-driven generator, particularly a kind of wind-driven generator.
Background technique
In the existing technology, in order to guarantee the safe operation of wind power generating set, the scientific design of wind-driven generator drive mechanism is seemed very necessary and urgent.Wind-driven generator Transmitted chains of the prior art adopts following design usually: main shaft, gear-box (speedup box) and generator.Blower fan is when real work, and main spindle's bears most of complicated wind load, thereby causes the thermal distortion and the resiliently deformable of main shaft, and these distortion can be directly delivered in the gear-box, causes the gear engagement dislocation in the gear-box; Use single shaft to hold support; The inner input shaft of gear-box bears outside the torque; Also need bear the radial and axial power of self bringing, the elastic support installation requirement of tooth case is high, causes extra tilting moment easily; The pretension that is difficult to realize elastic support guarantees the normal operation of Transmitted chains system to reduce rocking of tooth case.
Summary of the invention
The utility model technical problem to be solved is the deficiency to existing technology, provide a kind of rational in infrastructure, transmission ratio is high, guarantee the wind-driven generator Transmitted chains device of the smooth running of blower fan.
The utility model technical problem to be solved is to realize through following technological scheme.The utility model is a kind of Transmitted chains device of wind-driven generator, and it comprises main shaft and generator, is connected with gear-box between main shaft and the generator; Be characterized in: on the front and rear of main shaft, be respectively equipped with floating bearing and thrust-bearing; Described floating bearing and thrust-bearing are fixedly connected on the mainframe of wind-driven generator through its bearing support respectively.
In the Transmitted chains device of above-described the utility model wind-driven generator: preferably be connected between described generator and the gear-box through the diaphragm type coupling; Preferably be connected between described gear-box and the main shaft through lock sleeve.Also can adopt conventional Placement of the prior art.
In the Transmitted chains device of above-described the utility model wind-driven generator: the hot charging mode that all preferably adopts the induction heating bearing when described floating bearing and thrust-bearing and spindle mounted.
In the Transmitted chains device of above-described the utility model wind-driven generator: described floating bearing and thrust-bearing type all preferably adopt the center-adjusting sphere roller bearing.
The Transmitted chains device of the utility model wind-driven generator is employed in the mode that two cover bearing uniies are installed on the main shaft, does not have axial positioning design owing to be located at the anterior floating bearing of main shaft, when blower fan rotates, is small quick condition; Be provided with the axially locating design and be located at the main shaft rear portion near the thrust-bearing of gear-box, when blower fan rotated, axial position can not be subjected to displacement.Floating bearing can digest tilting moment and the radial force that rotate to produce from wind wheel, and the thrust-bearing of rear axial limiting bears the axial force and the radial force due to the wind wheel inclination angle of coming.
Compared with prior art, the utility model device has improved the force-bearing situation of gear-box greatly, has eliminated the influence of extraneous load to gear-box basically; Gear-box does not bear wind wheel weight and thrust, and transmitting torque has only reduced the complexity of tooth case load; The gear-box reliability improves greatly, and parts are easy for installation, and the operating space is big; When gear-box is carried out big upkeep operation, need not special frock wind energy is stablized, easy to maintenance.In addition, the center-adjusting sphere roller bearing that is adopted is widely used, and it is higher to domesticize, and with respect to biserial circular cone pipe bearing, not only can reduce cost, and the blower fan energy transfer is steady, and is convenient to safeguard and replacement; Guarantee the smooth running and the generating efficiency of blower fan better, significantly improve the total quality of blower fan.
