Abstract
The utility model discloses a wind -powered electricity generation main shaft, including axis body and boss, the axis body comprises the three -section, near being equipped with two rings shape steps on that section axis body of boss, is close to the one end of that section axis body of boss and passes through convex changeover portion and axle head flange joint, and the other end is equipped with chamfer, chamfer surface coating one deck wearing layer. The utility model discloses the practicality is strong, and the location is more swift during the installation, and setting up of wearing layer makes wind -powered electricity generation main shaft still keep fine intensity after the experience is rotatory many times, improves wind -powered electricity generation main shaft's life.
Description
Technical field
The utility model relates to technical field of wind power generation, particularly relates to a kind of wind power principal axis.
Background technique
In recent years, due to the continuous scarcity of natural resources, people comes for new energy, especially the exploitation of clean energy resource are also more and more positive, and wherein, wind-power electricity generation is because of its clean environment firendly, the advantage renewable, pollution-free, energy is large, prospect is wide, becomes the strategic choice of countries in the world.
Wind power technology equipment is the important component part of Wind Power Generation Industry, also be basis and the guarantee of Wind Power Generation Industry development, and wind power principal axis is as the core mechanical components of wind-driven generator, directly be connected with fan blade, formation diameter is about 80-90 rice and obtains huge wind wheel, and huge wind wheel carries natural wind and its energy is passed to generator by mechanical gear device and is converted into electric energy.But the restriction due to physical environment make the blade of huge wind wheel and wind power principal axis degrading, easily damage, add long rotation, wind power principal axis had higher requirement.
Model utility content
The technical problem that the utility model mainly solves is, provides that a kind of wear resistance is high, the wind power principal axis of longer service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of wind power principal axis, comprise axis body and boss, axis body is 3 stops multidiameter shaft, first ladder section of 3 stops multidiameter shaft is provided with two bulge loops, first ladder section is connected with the changeover portion of flange end by circular arc, the other end of the first ladder section is provided with chamfering, and chamfer surface applies one deck wearing layer.The chamfering place directly contacted with axis body in wind power principal axis rotary course is coated with coating rubbing-layer, adds the wear resistance of wind power principal axis, and the high flux cored wire of wear resistance can be selected to weld one deck wearing layer at chamfering place.
As further improvement of the utility model, boss is cylinder barrel shaped; Antirust oil reservoir is scribbled outside described axis body.Strengthen wind power principal axis antirust ability, extend its working life further.
The utility model still keeps good intensity after experience multiple rotary, and wear resistance is high, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of wind power principal axis of the utility model.
In figure: 1, axis body 2, boss 3, ring step 4, changeover portion 5, wearing layer.
Embodiment
Clearly understanding to have technical characteristics of the present utility model, object and effect, now contrasting accompanying drawing and describing embodiment of the present utility model in detail.
As shown in Figure 1, a kind of wind power principal axis, comprise axis body 1 and boss 2, axis body 1 is formed by three sections, that section of axis body 1 near boss 2 is provided with two ring steps 3, be connected with boss 2 by the changeover portion 4 of circular arc near one end of that section of axis body 1 of boss 2, the other end is provided with chamfering, and chamfer surface applies one deck wearing layer 5.Boss 2 is cylinder barrel shaped; Antirust oil reservoir is scribbled outside described axis body 1.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
Claims (2)
