Description
Technical field
The utility model relates to the technical fields of main shaft bearing oil leak, refer in particular to a kind of wind driven generation set main shaft
Bearing (ball) cover centering tooling.
Background technique
Known in the industry, the double-feedback aerogenerator group of big megawatt of dual-support structure, there are two main on transmission chain main shaft
Axle bearing, bearing sealing structure for main shaft belongs to static rotatory sealing, with bearing block, end cap, oil sealing cover board when workshop is assembled
On main shaft, structure is made of sealing ring, end cap, oil sealing cover board, bearing block, main shaft.Wherein sealing ring is mounted on end cap
Interior (being positioned by end cap), seal lip radial direction banding main shaft outer round surface；Oil sealing plate shaft is to compression sealing ring and is fixed on end
It covers；End cap is finally fixed on bearing block.Sealing ring is circular to be mainly also textile rubber oil seals using clamping cloth sealing ring, by main lip
It is formed with auxiliary lip, main lip main seal grease, the main dust-proof antiultraviolet auxiliary seal of auxiliary lip.End cap and bearing block are casting,
It is bolted and fixes.
Inclination angle, vibration, bearing clearance, sealing ring mass defect (magnitude of interference is small), components deviation during fan operation
Etc. factors, cause the generally existing main shaft bearing oil leak problem of the double-feedback aerogenerator group of current dual-support structure, leak
Oil will cause bearing because oil starvation overtemperature, bearing wear, it is serious lead to bearing failure, fan operation and maintenance bring inconvenience even
Heavy economic losses.
Currently, there is the main reason for main shaft bearing oil leak in the double-feedback aerogenerator group of dual-support structure
By are as follows: 1, sealing ring design defect；2, it is shaken in unit running process；3, end cap parts design tolerance is unreasonable, components
The factors such as mismachining tolerance is big, components installation deviation accumulated error is big, causing sealing gap occur leads to main shaft bearing sealing leakage
Oil.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art and disadvantage, propose it is a kind of it is structurally reasonable it is reliable,
Wind driven generation set main shaft bearing (ball) cover centering tooling easy to use can effectively solve current dual-support structure double-fed type wind
The main shaft bearing oil leak problem of power generator group, to improve unit operation stability.
To achieve the above object, a kind of technical solution provided by the utility model are as follows: wind driven generation set main shaft bearing
End cap centering tooling, wherein the centering tooling is irregular frustum cone structure, and the side of the frustum cone structure is one parallel
In the side grain of rotary table axis, and the side grain be vertically cut from an end face of rotary table toward other end direction, and
The other side of the frustum cone structure remains as the arc surface with taper.
The threaded hole for having one Yu the same axis of rotary table, and the threaded hole are run through in the intermediate position of the frustum cone structure vertically
It is configured with a screw rod as rotary table handle.
The large end face of the frustum cone structure offers a technique identifying hole, carries out using which certain face as large end face
Processing.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
1, this centering tooling is small, is convenient for carrying, and reusable, and fabricates at low cost.
2, using consumptive material is not necessarily to during the adjustment of this centering tooling, cost of adjusting economy is extremely low, and Adjustment precision is high, Neng Goubao
End cap centering installation deviation≤0.2mm is demonstrate,proved, economically is suitable for promoting with application effect.
In short, main shaft bearing oil leak can be effectively solved the problems, such as using this centering tooling, so that it is steady to improve unit operation
It is qualitative, there is actual promotional value.
Detailed description of the invention
Fig. 1 is the main view of the utility model tooling.
Fig. 2 is the top view of the utility model tooling.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Referring to figure 1 and figure 2, wind driven generation set main shaft bearing (ball) cover centering tooling provided by the present embodiment, tool
Body is irregular frustum cone structure, wherein the side of the frustum cone structure is the side grain 11 for being parallel to rotary table axis, and
The side grain 11 is vertically to cut from an end face of rotary table toward other end direction, and the other side of the frustum cone structure
Remain as the arc surface 12 with taper；The screw thread for having one Yu the same axis of rotary table is run through at the intermediate position of the frustum cone structure vertically
Hole 13, and the threaded hole 12 is configured with a screw rod (not shown) as rotary table handle；The frustum cone structure it is big
End face offers a technique identifying hole 14, is processed using which certain face as large end face.
The following are the end cap methods of adjustment of the above-mentioned wind driven generation set main shaft bearing (ball) cover centering tooling of the present embodiment, use
When, first unscrew bolt of cover, 120 ° using on end cap equally distributed three fabrication holes, will as centering tooling placement location benchmark
Three centering toolings are inserted into the sealing ring installation cavity of end cap simultaneously, and the corresponding fabrication hole of a centering tooling, and are required
The small end face of centering tooling deviates from main shaft bearing towards main shaft bearing, large end face, and side grain 11 is contacted with main shaft outer circle, and with cone
The arc surface 12 of degree is then contacted with sealing ring installation cavity wall, and the length ruler of end cap portion is then exposed by measurement centering tooling
It is very little, end cap alignment deviation is conversed according to trigonometric function, adjusts end cap position further according to deviation, it will be able to make end cap and main shaft
With one heart, Concentricity tolerance≤0.2mm of rear end cap and main shaft is adjusted, circle to be sealed in this way is mounted in end cap, end cap and main shaft
After centering, sealing ring also can be realized with main shaft centering, and would not be deposited between the lip after sealing ring centering and main shaft outer circle
In gap, to effectively solve the problems, such as oil leak.
Main shaft bearing oil leak handles drive end bearing bracket centering maximum deviation 0.7mm, and with after this centering tooling again centering
Maximum deviation 0.2mm.It was verified after processing by 5 months, the slight permeability of sealing ring reaches treatment effect.Therefore, the utility model
Provided centering tooling and its method of adjustment can effectively solve the problems, such as main shaft bearing oil leak, and the figure of centering tooling
It is small, it is convenient for carrying, and reusable, processing and manufacturing is at low cost, is not necessarily to consumptive material, cost of adjusting economy pole during the adjustment
It is low, it can guarantee end cap centering installation deviation≤0.2mm according to the utility model method Adjustment precision height, economically and answer
All there is practical popularization with effect, be worthy to be popularized.
Embodiment described above is only the preferred embodiment of the utility model, not limits the utility model with this
Practical range, therefore all shapes according to the utility model, change made by principle, it should all cover in the protection scope of the utility model
It is interior.
