Abstract
The present invention relates to wind-driven generator which belongs to electricity generator field. Characteristic is: turning supporting bearing is mounted on front side wall hole of chassis; hub connects with front side wall of chassis by turning supporting bearing; hub connects with one end of soft connection coupling through turning supporting bearing; other end of soft connection coupling connects with gear box. Hub of the present invention is fixed on chassis of wind power generator by turning supporting bearing, and connects with gear box by soft connection. By soft connection, direct influence gear box is avoided by impulse force of direct wind, and normal work of gear box is assured, at the same time axial direction dimension of wind power generator can be decreased.
Description
One, technical field
The present invention relates to a kind of wind-driven generator, belong to electrical generator fields.
Two, background technique
In wind-driven generator is used, the damage of gear-box mainly is because the quick variation of wind speed and direction, blade pass is crossed wheel hub and torque and power are directly passed to main shaft is passed to gear-box again, and all mechanisms connect firmly without any buffering, frequent changes and the torque and the power that have impact are acted directly on the gear-box, and therefore the life-span of gear-box reduces.
Three, summary of the invention
The object of the present invention is to provide a kind of impact torque and the power that can alleviate gear-box greatly and born, the wind-driven generator that has prolonged the working life of gear-box.
Technical solution: slewing bearing is installed on the front side cinclides on chassis, wheel hub is connected with the front panel on chassis by slewing bearing, wheel hub passes slewing bearing and is connected with coupling one end that is flexible coupling, and the other end of the coupling that is flexible coupling is connected with gear-box.
The rotary inner ring of wheel hub and slewing bearing is by bolton, and the fixedly outer ring of slewing bearing and the front side plate on chassis pass through bolton.
The rotation outer ring of wheel hub and slewing bearing is by bolton, and the fixedly inner ring that revolution is supported and the front side plate on chassis are by bolton, and vice versa.
Being shaped as of base plate " ".
The present invention is owing to wheel hub directly is connected with the wind-driven generator chassis by slewing bearing, wheel hub can be rotated freely in chassis side, main shaft is connected with gear-box by the coupling that is flexible coupling, so avoid of the influence of the direct Thrust of wind by being flexible coupling to gear-box, guarantee the proper functioning of gear-box, can reduce simultaneously the axial dimension of wind-driven generator, the present invention has prolonged the life-span of wind-driven generator wheel-box greatly owing to alleviated impact torque and axial and the radial force of the quick variation of wind speed and direction to gear-box.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention;
Five, embodiment
The selection of coupling 4 can be selected different soft binding coupling according to different blower fans.
The selection of coupling 4 can be selected different soft binding coupling according to different blower fans.
