Abstract
The utility model relates to a wind generator, belonging to the generator field. The wind generator is characterized in that a slewing bearing is mounted on a front lateral wall hole of a chassis, a hub is connected with the front lateral wall of the chassis through the slewing bearing, the hub penetrates through the slewing bearing to be connected with one end of a flexible coupling, and the other end of the flexible coupling is connected with a gear box. The hub of the wind generator is fixed on the chassis of the generator through the slewing bearing, and is connected with the gear box via flexible connection. The direct wind thrust can be avoided to directly affect the gear box through the flexible connection, thereby guaranteeing the normal operation of the gear box, and simultaneously reducing the axial size of the wind generator.
Description
One, technical field
The utility model relates to a kind of wind-driven generator, belongs 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 purpose of this utility model 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 utility model 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 utility model 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 the utility model structural representation;
Five, embodiment
The utility model chassis 5 is shaped as
Chassis 5 front panels have the hole, slewing bearing 2 is housed on the hole, wheel hub 1 passes through bolton with the rotary inner ring of slewing bearing 2, the fixedly outer ring of slewing bearing 2 and the front side plate on chassis 5 pass through bolton, the slewing bearing 2 that wheel hub 1 passes on 5 front panels of chassis is connected with coupling 4 one ends that are flexible coupling, and the other end of the coupling 4 that is flexible coupling is connected with gear-box 3.
The selection of coupling 4 can be selected different soft binding coupling according to different blower fans.
The utility model chassis 5 is shaped as
Chassis 5 front panels have the hole, slewing bearing 2 is housed on the hole, wheel hub 1 passes through bolton with the rotation outer ring of slewing bearing 2, the fixedly inner ring of revolution support 2 and the front side plate on chassis 5 pass through bolton, the slewing bearing 2 that wheel hub 1 passes on 5 front panels of chassis is connected with coupling 4 one ends that are flexible coupling, and the other end of the coupling 4 that is flexible coupling is connected with gear-box 3.
The selection of coupling 4 can be selected different soft binding coupling according to different blower fans.
