Description
Technical field
The utility model belongs to wind power principal axis processing technique field, and in particular to a kind of wind power principal axis sandblasting protective tooling.
Background technique
Wind power principal axis needs to carry out anti-corrosion protective treatment, base after finishing according to the spraying position that drawing marks
Preservative treatment includes: waxing protection, paint anti-corrosion, spray zinc processing in sheet, smears the conventional means such as antirust oil.As shown in Figure 1,
Region shown in mark 1 need to carry out paint anti-corrosion in figure, and region shown in mark 2 need to carry out waxing protection.Wherein carry out paint anti-corrosion
Place, in order to increase paint adhesion, these usual positions need to carry out blasting treatment after cleaning up.But whole main shaft has
A little places need to install bearing or assemble (such as main shaft bearing shelves) with gear-box, these position dimension required precisions are very high,
Surface roughness all provides Ra≤1.6 μm substantially, these positions (region shown in mark 3) only allow to smear the anti-of easy cleaning
Rust oil carries out antirust treatment, and main shaft is transported to assembly shop and carries out in installation process, can be straight as long as cleaning up antirust oil
It connects installation bearing block or is packed into gear-box.And consider that not generating sundries in subsequent assembling process influences cooperation precision, these are heavy
Position is wanted to be inconjunction with fillet and step side and do not allow to carry out other anti-corrosion process for protecting in addition to smearing antirust oil.Cause
This, protection of the wind power principal axis critical positions in sandblasting process is crucial.
Existing protection method is using rubber skin by the cladding of region shown in mark 3, and both ends use iron straps band tightener
It is fixed.The disadvantages of this method are: the fillet position of rubber skin and wind power principal axis cannot be intact when with iron straps screw banding rubber skin
Fitting, and step side can not protect well, cause these positions that can also be sprayed onto a small amount of sand grains, cause work
Part finish is inadequate, influences product subsequent installation.
Summary of the invention
Therefore, in the prior art the technical issues of, the purpose of this utility model is to provide a kind of sprays of wind power principal axis
Sand protective tooling, the wind power principal axis sandblasting protective tooling of the utility model can effective protection include the big stepped diameters side in top,
One protection comprehensively is realized at the positions such as fillet and bearing guard, and easy for installation, and a specification wind power principal axis need to only do a set of work
Dress, is hardly damaged, production cost is low.
It should be noted that in present specification, the "up" and "down" is with for wind power principal axis, along wind-powered electricity generation master
Axis is axial, and "upper" corresponds to wind power main spindle big end direction, and "lower" corresponds to the small extreme direction of wind power principal axis.
The wind power principal axis sandblasting protective tooling of the utility model includes:
Rubber skin, for entangling the bearing guard or gear assembly position that wind power principal axis to be protected；
Guard ring, for the rubber skin upper end to be fixed on to the fillet position of wind power principal axis to protect wind power principal axis
At portion's fillet and major diameter step side, the guard ring include big step end face, arc transition section and small stair section, the circle
Arc changeover portion inner hole has circular arc excessive, and arc radius is identical as wind power principal axis radius of corner；
Iron straps screw assembly, for the rubber skin other end to be fixed on wind power principal axis, the iron sheet including hoop
Item and the screw and nut for connecting the iron straps both ends.
Preferably, hole size is greater than wind power principal axis corresponding position size among the guard ring, with just can be described
It subject to rubber skin banding, move rubber skin will not in sandblasting procedures or loose or dislocation.
Preferably, the upper step side size of the big step end face size of the guard ring and wind power principal axis corresponding position
It is identical, with this can all complete conjunction fitting be protected main shaft fillet position.
The positive effect of the utility model is:
The wind power principal axis sandblasting protective tooling of the utility model can effective protection include the big stepped diameters side in top, fillet
It integrally being protected comprehensively with positions, realizations such as bearing guards, and easy for installation, a specification wind power principal axis need to only do a set of tooling,
It is hardly damaged, production cost is low.

Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.It should be understood that following embodiment is only used for
Bright the utility model is not for restriction the scope of the utility model.
Embodiment 1
Fig. 2 show the wind power principal axis sandblasting protective tooling of the utility model preferred embodiment, including three groups, protects respectively
Three positions of wind power principal axis.Every group of tooling all includes rubber skin 51, guard ring 52 and iron straps screw assembly 53.Wherein rubber
Skin 51 entangles the bearing guard that wind power principal axis to be protected or gear assembly position；51 upper end of rubber skin is fixed on wind-powered electricity generation by guard ring 52
At top fillet of the fillet position of main shaft to protect wind power principal axis and major diameter step side；Iron straps screw assembly 53 includes
The iron straps of hoop and the screw and nut at connection iron straps both ends, 51 lower end of rubber skin is fixed on wind power principal axis.
In three groups of toolings, rubber skin 51 (as shown in Figure 3) and iron straps screw assembly 53 (as shown in Figure 4) shape and structure phase
Together, only protective position is corresponded in size to adjust.
Guard ring protects the top circle of wind power principal axis for rubber skin upper end to be fixed on to the fillet position of wind power principal axis
At angle and major diameter step side, guard ring 52 include big step end face 521, arc transition section 522 and small stair section 523, circle
522 sections of inner holes of arc transition have that circular arc is excessive, and arc radius is identical as wind power principal axis corresponding position radius of corner.Shown in Fig. 5 a-5c
The respectively from top to bottom guard ring 52 in three groups of toolings, the corresponding protective position of the guard ring 52 of three groups of toolings in planform and
Size adjusts respectively.
When actual assembled, antirust oil is coated at the position that wind power principal axis does not need paint, winds film oil sealing, bubble wrap with PE
Film is pasted around a circle with adhesive tape, and last surface is protected with rubber skin 51, loads onto guard ring in corresponding size stepped portions
52,51 upper end of rubber skin is fastened, iron straps screw assembly 53 is loaded on, fastens 51 lower end of rubber skin.
Note:
Key point 1, guard ring inner hole have that circular arc is excessive, and arc radius angle must be identical as wind power principal axis radius of corner.
Inner hole palpus strict control hole size and major axis size gap among key point 2, guard ring, just protection packet
Rubber skin banding is filled, move rubber skin will not in sandblasting procedures or loose or dislocation.
Key point 3, the big step end face size of guard ring must be identical as the upper step side size that wind power principal axis protects,
It can all complete conjunction fitting be protected main shaft fillet position.
From the foregoing, it will be observed that the wind power principal axis sandblasting protective tooling of the utility model can effective protection include the big stepped diameters in top
One protection comprehensively is realized at the positions such as side, fillet and bearing guard, and easy for installation, and a specification wind power principal axis need to only be done
A set of tooling, is hardly damaged, and production cost is low.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
