Abstract
The utility model provides a kind of attachment structure of bearing of wind power generator and end cap, including bearing block, the bearing on bearing block, the end cap being fixedly connected with the bearing seat.Adjustment mechanism is set between bearing outer ring and end cap, it is described that there is gap between bearing and end cap.By increasing adjustment mechanism, it is not directly contacted between bearing and end cap, and retains certain gap, end cap arrangement caused by overcoming mismachining tolerance is overproof.By optimizing bearing (ball) cover structure, increase adjustment mechanism and the structure type for compressing adjustment mechanism and bearing using holding screw, it is overproof that the end cap arrangement caused by mismachining tolerance can be effectively reduced, improve assembly precision and assembling speed can be effectively improved, and then improve the service life of base bearing and the stability of whole driving-chain.
Description
Technical field
The utility model belongs to technical field of wind power generation, and in particular to a kind of connection of bearing of wind power generator and end cap
Structure.
Background technology
In wind power generating set drive mechanism, base bearing bears more heavy loads under complex working condition, wherein bearing axial direction
Load is the wind power generating set a great problem to be solved, and this axial load is by rational driving-chain structure type solution
Certainly, if solved bad, it will produce impact to base bearing and gearbox.Because wind power generating set bears the special of load
Property, its frequency is very high, and processing is bad, and base bearing and gear-box are all quickly invalidated, and transmission system failure can not only produce great peace
Full hidden danger, and change difficult, shuts down causes energy loss excessive for a long time, add the maintenance workload of owner and safeguard into
This.
The base bearing external toothing of prior art directly contacts with bearing block and bearing (ball) cover, and by bearing block and bearing (ball) cover
Bearing outer ring is fastened, it is inconsistent due to product manufacturing tolerance, it is desirable to which that every unit all according to different tolerance particular arrangements, is matched somebody with somebody
It is high to close required precision, is easy to cause to configure overproof, causes end cap to cancel.
Utility model content
The utility model provides a kind of attachment structure of bearing of wind power generator and end cap, overcomes existing base bearing external tooth
Circle directly contacts with bearing (ball) cover, easily causes the problems such as end cap is scrapped.
The attachment structure of bearing of wind power generator and end cap provided by the utility model, including bearing block, installed in bearing
Bearing on seat, the end cap being fixedly connected with the bearing seat.On the basis of existing technology, the utility model is also made changes as follows
Enter：Adjustment mechanism is set between bearing outer ring and end cap, it is described that there is gap between bearing and end cap.By increasing adjustment machine
Structure, it is not directly contacted between bearing and end cap, and retains certain gap, end cap arrangement caused by overcoming mismachining tolerance is overproof.
Further, the adjustment mechanism is a pad.
Further, top wire hole is provided with the end cap, holding screw is inside set and compresses adjustment mechanism, only need holding screw
Together with bearing, adjustment mechanism being closely connected with end cap three, assembly manipulation is simple, maintenance easy to disassemble, improves dress
With efficiency and assembly precision.
Preferably, the adjustment mechanism has 4mm gaps with end cap.
Preferably, there is 2mm gaps between the bearing and end cap.
Further, the end cap is arranged on bearing block by high-strength bolt.
Further, plain washer is provided between the nut and end cap of the high-strength bolt.
The beneficial effects of the utility model：By optimizing bearing (ball) cover structure, increase adjustment mechanism and using holding screw
The structure type that adjustment mechanism and bearing are compressed, it is overproof to effectively reduce the end cap arrangement caused by mismachining tolerance, improves
Assembly precision simultaneously can effectively improve assembling speed, and then improve the service life of base bearing and the stability of whole driving-chain.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model structure,
Fig. 2 is the scheme of installation of pad in embodiment.
1st, bearing block, 2, bearing, 3, end cap, 4, pad, 5, high-strength bolt, 6, plain washer, 7, holding screw.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model, it is impossible to be interpreted as the restriction to the specific protection domain of the utility model.
Embodiment
Reference picture 1, the attachment structure of the bearing of wind power generator and end cap, including bearing block 1, with the endoporus of bearing block 1
The bearing 2 that gap coordinates, the front end of bearing block 1 are provided with shoulder, coordinate with the outer ring front end face of bearing 2, bear axial load.
The bearing 2 is provided with end cap 3 with the rear end face of bearing block 1, and the end cap 3 is arranged on bearing block 1 by high-strength bolt 5, institute
State and plain washer 6 is provided between the nut of high-strength bolt 5 and end cap 3, and apply fluid sealant in mating surface and effectively sealed.Reference picture
2, adjustment mechanism is set between the outer ring of bearing 2 and end cap 3, and the adjustment mechanism is a pad 4.Opened on the end cap 3
There is top wire hole, inside set the compress gasket 4 of holding screw 7, the pad 4 and holding screw 7, which coordinate, ensures the outer ring of bearing 2 and end cap 3
Between there is 2mm gaps (as shown in 2mm positions in Fig. 2), meanwhile, 4mm gaps are left between pad 4 and end cap 3 (in such as Fig. 2
Shown in 4mm positions).By increasing pad 4, it is not directly contacted between bearing 2 and end cap 3, and retains certain gap, effectively Du
On business poor overproof caused end cap cancels absolutely.Holding screw 7 is only needed to assemble bearing 2, pad 4 and the axial compression of end cap 3
Precision is high, and operation is simple and reliable, maintenance easy to disassemble, improves efficiency of assembling and saves maintenance cost.
