Description
Technical field
This utility model belongs to field of wind power equipment, especially a kind of drive shaft support structure of wind-driven generator.
Background technology
Wind energy, as a kind of regenerative resource of cleaning, is increasingly paid attention to by countries in the world.And it is inexhaustible,
Nexhaustible.For hydropenia, short bunker and ungetable offshore islands, Pastoral Areas, mountain area and plateau area, treatment in accordance with local conditions
Utilize wind-power electricity generation, be especially suitable for, be well worth doing.THE WIND ENERGY RESOURCES IN CHINA is enriched, through statistics, the wind energy storage that can develop
Amount about 1,000,000,000 kW, wherein, land wind energy content about 2.53 hundred million kW, the development prospect of wind-power electricity generation is boundless.
Device required for wind-power electricity generation, referred to as wind power generating set, 1.5MW wind power generating set per hour may be used when completely sending out
Convey 1500 degree of electricity to electrical network.Wind power generating set is commonly divided into wind wheel, cabin and steel tower three part.Wherein, steel tower is
The framework of supporting wind wheel, tail vane and electromotor, it typically builds higher, in order that obtaining larger and more uniform wind
Power, has enough intensity again；Wind wheel is the vitals that the kinetic energy kept watch is changed into mechanical energy, when wind is to paddle, oar
Producing aerodynamic force on leaf drives wind wheel to rotate；Cabin is the key equipment of wind-driven generator, including gear-box, electromotor, safeguards
Personnel can also enter cabin by wind generator tower.
Power transmission shaft is the vitals that the potential energy rotating blade is delivered to electromotor, and power transmission shaft also holds while rotating
By the pressure of windward side, after life-time service, the abrasion between power transmission shaft and bearing aggravates, and moment of torsion increases, and affects work efficiency.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, design science,
It is easy to assembling, the drive shaft support structure of the wind-driven generator of firm and durable.
This utility model solves its technical problem and takes technical scheme below to realize：
A kind of drive shaft support structure of wind-driven generator, one end of power transmission shaft is stretched into machinery space bulkhead inside and is co-axially mounted connection
Axial organ, this shaft coupling is used for connecting the input shaft of gear-box；The other end of power transmission shaft stretches out outside machinery space bulkhead and connects wheel hub, wheel hub
For install blade and by blade drive rotation it is characterised in that：It is set with power transmission shaft between wheel hub and machinery space bulkhead
One bearing block, this bearing block is bolted on machinery space bulkhead by the multiple of radial equipartition；Power transmission shaft in bearing block covers
Equipped with a floating bearing, the power transmission shaft between bearing block and wheel hub is formed with a support convex shoulder；In floating bearing and machinery space bulkhead
Between bearing block in be coaxially installed with spring bearing and airtight and watertight padding.
And, it is formed with an annular spacing groove in the bonding station of machinery space bulkhead and valve seat and be coaxially installed with a spacing ring.
And, support the axis hole being less than bearing block with diameter greater than power transmission shaft of convex shoulder.
Advantage of the present utility model and good effect are：
This utility model reasonable in design, firm and durable, long service life, can preferably carry and axially press windward
Power, reduces moment of torsion, can wind-power electricity generation work under the multiple weather conditions of long-time bearing, reliability and durability.
Brief description
Fig. 1 is this structural representation.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are simply retouched
The property stated, be not determinate it is impossible to limit protection domain of the present utility model with this.
A kind of drive shaft support structure of wind-driven generator, is illustrated with direction shown in accompanying drawing 1 for the ease of description, passes
Moving axis direction is axially, and one end of power transmission shaft 7 is stretched into machinery space bulkhead 5 inside and is co-axially mounted shaft coupling 8, and this shaft coupling is used for connecting
The input shaft of gear-box；The other end of power transmission shaft stretches out outside machinery space bulkhead and connects wheel hub 1, and wheel hub is used for installing blade and by oar
Leaf drives windward, thus driving power transmission shaft to be rotated；
Innovative point of the present utility model is：
One bearing block 4 is set with the power transmission shaft between wheel hub and machinery space bulkhead, this bearing block passes through the many of radial equipartition
Individual bolt 6 is fixed on machinery space bulkhead；
One floating bearing 3 is set with the power transmission shaft in bearing block, the power transmission shaft between bearing block and wheel hub is made
There is a support convex shoulder 2, support the axis hole being less than bearing block with diameter greater than power transmission shaft of convex shoulder, this support convex shoulder bears axial compressive force
When to floating bearing compression, flexible communication torque coaxially buffers axial compressive force.
In order to ensure bearings power, in the bearing block between floating bearing and machinery space bulkhead, it is coaxially installed with spring bearing
11 and airtight and watertight padding 10, it is formed with an annular spacing groove in the bonding station of machinery space bulkhead and valve seat and be coaxially installed with a spacing ring 9,
Limit filler installation site and ensure sealing.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art is permissible
