Description
Technical Field
The utility model relates to a locking dish for wind power generation.
Background
Wind-powered electricity generation locking dish is the no key connection device that is used for fan main shaft and gear box to be connected widely on the world at present, and wind-powered electricity generation locking dish includes outer loop, inner ring and bolt. In the assembling process, the wind power locking disc is subjected to axial force generated by pre-tightening of the bolts, so that conical surfaces between the inner ring and the outer ring interact to generate radial force, a planet carrier in the gear box tightly holds the main shaft, and finally the main shaft is connected with the gear box. After the connection is accomplished, the frictional force between planet carrier and the main shaft can produce the moment of torsion, and then realizes the transmission and connect, but after the equipment is accomplished, wind-powered electricity generation locking dish's conical surface stress is great, can finally lead to the higher region of stress on the conical surface can take place the phenomenon of conical surface fish tail after a lot of dismouting, then can't produce interference fit, consequently the locking dish is scrapped.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide a locking dish for wind power generation, can prolong its life.
In order to realize the technical effects, the utility model adopts the technical scheme that: the locking disc for wind power generation comprises an inner ring and an outer ring connected with the inner ring through a plurality of fasteners, wherein the outer ring is provided with a step-shaped inner wall, the step-shaped inner wall comprises a cylindrical surface located on the upper portion and a conical surface located on the lower portion and connected with the cylindrical surface, the inner ring comprises an end plate and a bushing, the outer surface of the end plate is attached to the cylindrical surface, the outer surface of the bushing is attached to the conical surface, the end plate and the outer ring are fixedly connected through the fasteners, the locking disc is characterized in that the end plate comprises an end plate body and a cushion ring located below the end plate body, the outer diameter of the cushion ring is the same as the outer diameter of the end plate body, the inner diameter of the cushion ring is the same as the maximum diameter of the bushing, and a cylindrical guide surface with the height being the same as the thickness of.
In a further improvement, at least one end face of the backing ring and two end faces of the end plate body are provided with reticulate patterns.
In a further refinement, the fastener is a bolt.
In a further improvement, the fasteners are evenly distributed on a circumference centered on an axial line of the bushing.
The utility model has the advantages and the beneficial effects that: through improving the inner ring, design into the disconnect-type with the end plate, divide into end plate body and backing ring promptly, use the initial stage at the locking dish, be located end plate body below with the backing ring, realize locking work, dismantle for a long time and take place wearing and tearing phenomenon after, place in end plate body top after dismantling the backing ring from end plate body below, because be the conical surface on outer loop and the bush, after dismantling the backing ring, can make the bush remove the certain distance downwards, realize the interference fit once more of bush and outer loop from this, therefore, the life of its part has been prolonged.
Drawings
FIG. 1 is an outer ring schematic;
figure 2 is a schematic diagram of the inner ring.
In the figure: 1. an outer ring; 2. an end plate body; 3. a backing ring; 4. a bushing; 5. a fastener.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2, the locking disk for wind power generation comprises an inner ring and an outer ring 1 connected with the inner ring through a plurality of fasteners, the outer ring 1 is provided with a step-shaped inner wall, the step-shaped inner wall comprises a cylindrical surface positioned at the upper part and a conical surface positioned at the lower part and jointed with the cylindrical surface, the inner ring comprises an end plate and a lining, the outer surface of the end plate is attached to the cylindrical surface, the outer surface of the bush 4 is attached to the conical surface, the end plate is fixedly connected with the outer ring through a plurality of fasteners 5, the end plate comprises an end plate body 2 and a backing ring 3 positioned below the end plate body 2, the outer diameter of the backing ring 3 is the same as that of the end plate body 2, the inner diameter of the backing ring 3 is the same as the maximum diameter of the bushing 4, and a cylindrical guide surface having the same height as the thickness of the backing ring 3 is provided above the bushing 4.
The principle of the utility model is as follows: when backing ring 3 is located end plate body 2 below, the interference fit is realized under fastener 5 effect in the complete laminating of the conical surface of its installation position external surface and outer loop 1 of bush 3, after taking place wearing and tearing when dismantling many times, produced the clearance between the part of bush 4 and the conical surface of outer loop 1, consequently, can't realize closely laminating at original installation position, when removing backing ring 3 after, fastener 5 is locked, backing ring 3 can move down the distance that is not more than backing ring thickness, be equivalent to having increased the diameter of bush 4 in the same junction of outer loop 1 from this, can make the two carry out interference fit once more for this, thereby the life of locking dish has been prolonged, just can scrap the locking dish when having removed backing ring 3 thickness and all can't realize interference fit.
The preferred embodiment in this embodiment does, at least an terminal surface of backing ring 3 and the both ends face of end plate body 2 all has the reticulation structure, through set up the reticulation structure on the terminal surface of backing ring 2 and end plate body 3, has increased certain frictional force between the two then for when locking through the fastener, both can not take place the skew phenomenon, convenient operation.
In the present embodiment, the fastening member 5 is preferably a bolt.
In the preferred embodiment, the fastening elements 5 are uniformly distributed on the circumference of the bushing 4 around the axial line.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
