Abstract
The utility model discloses a supporting device for a spindle of a wind driven generator, which belongs to the technical field of wind driven generators and comprises a bearing pedestal fixed on an underbed and a bearing arranged in the bearing pedestal. The spindle penetrates through the bearing which comprises a double-row cylindrical bearing arranged at the front end in the bearing pedestal and a double-row conical bearing arranged at the rear end in the bearing pedestal. The utility model has the beneficial effects of reducing the damage caused by the impacting of a driving chain system of a wind driven generating set to a speed-up box under cyclic loading of a wind wheel, prolonging the service life of the speed-up box, and improving the stability and reliability of a unit.
Description
Technical field
The utility model belongs to technical field of wind power generator, particularly a kind of wind driven generator principal shaft support device.
Background technique
At present, present common MW class blower fan develops rapidly at home, and the Transmitted chains form is different, and the Transmitted chains structural type of common in the market blower fan mainly is divided into direct-driving type, half direct-driving type and double-fed, wherein the double-fed type has accounted for more than 80% of market total quantity, is the leading type in market.In the double-fed type of existing market, the main shaft support form of most blower fans is that single shaft holds support, and this structure directly passes to the alternate load that the blower fan wind wheel produces on the speedup box, and is very big to the impact of speedup box, very easily damage the preceding step bearing of speedup box, very big to the influence in working life of speedup box.The part blower fan adopts the duplex bearing form, but all adopts two separate bearings stand structure forms, and it is big that difficulty is adjusted in installation, because bearing is selected selfaligning roller bearing for use, can not block the impact of wind wheel alternate load to speedup box fully.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of wind driven generator principal shaft support device, it has reduced wind power plant Transmitted chains system and under the wind wheel alternate load speedup box has been impacted the infringement that causes, prolong the working life of speedup box, improve the stability and the reliability of unit.
The utility model is realized by following measure:
Wind driven generator principal shaft support device of the present utility model, comprise the bearing support that is fixed on the underframe and be arranged on the interior bearing of bearing support, main shaft passes bearing, and described bearing comprises the biserial cylindrical bearing that is arranged on the bearing support Inner Front End and is arranged on the biserial conical bearing of rear end in the bearing support.
Above-mentioned biserial cylindrical bearing is fixed by bearing (ball) cover, and the biserial conical bearing is fixed by the axle head gland.
In order to reduce wearing and tearing, be provided with spacer between bearing support inwall and the main shaft.
The beneficial effects of the utility model are: biserial cylindrical bearing 3 can allow axially motion among a small circle at axial slip, mainly bears the radial load of wind wheel to main shaft; Biserial conical bearing 5 both can bear the radial load of wind wheel to main shaft by the pretension location simultaneously, also can bear the thrust load of wind wheel to main shaft.Therefore reduce wind power plant Transmitted chains system and under the wind wheel alternate load, speedup box has been impacted the infringement that causes, prolonged the working life of speedup box, improved the stability and the reliability of unit.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Among the figure: 1, main shaft, 2, bearing support, 3, the biserial cylindrical bearing, 4, spacer, 5, the biserial conical bearing, 6, the axle head gland, 7, locking nut.
Embodiment
As shown in Figure 1, wind driven generator principal shaft support device of the present utility model comprises bearing support 2, biserial cylindrical bearing 3, biserial conical bearing 5, spacer 4, bearing (ball) cover and axle head gland 6.Bearing support 2 is fixed on the underframe of equipment, and biserial cylindrical bearing 3 is arranged on bearing support 2 Inner Front Ends, and fixes with bearing (ball) cover, and biserial conical bearing 5 is arranged on rear end in the bearing support 2, and fixing with axle head gland 6.Main shaft 1 passes biserial cylindrical bearing 3 and biserial conical bearing 5, is with spacer 4 between bearing support 2 inwalls and the main shaft 1, can play the effect that reduces to wear and tear.
The bearing that assembles is connected with speedup box with bearing support 2 constituent elementss, forms the Transmitted chains structure of blower fan.The biserial cylindrical bearing 3 of Transmitted chains structure front end can allow axially motion among a small circle at axial slip, mainly bears the radial load of wind wheel to main shaft 1; The biserial conical bearing 5 of Transmitted chains structure rear end both can bear the radial load of wind wheel to main shaft 1 by the pretension location, also can bear the thrust load of wind wheel to main shaft 1.Therefore the impulsive load of front end input is cut off fully, be input to by bearing support 2 in the underframe of equipment, rather than back kick is delivered in the speedup box, plays the effect of protection speedup box.Biserial cylindrical bearing 3 and biserial conical bearing 5 are encapsulated in the same stiff shaft bearing 2, can well block the alternating shock load of wind wheel, well protect the speedup box of rear end to avoid damage, the working life of the speedup box of raising.
Its assembly process is: in the bearing support 2 of earlier spacer 4 being packed into, bearing support 2 front ends of again biserial cylindrical bearing 3 being packed into are fixed with bearing (ball) cover; Bearing support 2 rear ends of then biserial conical bearing 5 being packed into, fixing with axle head gland 6, after main shaft 1 is packed in the member, carry out fastening with locking nut 7 at last.Bearing support 2 is connected with the underframe of equipment by high-strength bolt.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
