Abstract
The invention relates to a novel limiting structure of a bearing in a wind power gear box. The structure comprises a bearing and a bearing pedestal. A keyway corresponding to a key is arranged between an outer ring of the bearing and the bearing pedestal, and the outer ring of the bearing and the bearing pedestal are locked and located through the key. In the novel limiting structure provided by the invention, as the keyway corresponding to the key is arranged between the outer ring of the bearing and the bearing pedestal, and the outer ring of the bearing and the bearing pedestal are locked and located through the key, the failure risk caused by relative slippage is effectively avoided.
Description
Technical field
The present invention relates to the spacing new knot of a kind of gear-box middle (center) bearing position limiting structure, especially wind turbine gearbox middle (center) bearing
Structure, belongs to mechanical field.
Background technology
Bearing has a very wide range of applications in the industry, and indispensable effect is played in power transmittance process.
During bearing application, its outer ring is typically arranged in bearing block by interference mode, and frictionally is prevented
Relative motion between bearing and bearing block.Due to by bearing block rigidity or bearing rigidity affected and the course of processing in work
, often there is bearing outer ring in skill deviation and bearing block occurs the relative case slided, and this situation occurs for a long time can cause axle
The abrasion of bearing outer-ring and bearing block faying face, causes junction to be failed, because the impurity that abrasion is produced also results in bearing in rolling
Rapid failure during dynamic.
Wind resource is green regenerative energy sources, inexhaustible.At present many countries are for environmental conservation
Consider, be devoted to develop wind resource.The wind power equipment market of Europe and other developed countries is especially hot.The Chinese government is near
Also the exploitation of wind-driven generator is attached great importance to over year, domestic localization of wind power equipment manufacturing also develops constantly.At present, with
Based on 1.5MW～6MW serial fans, and mass production is had been achieved with, 3MW～6MW series is the trend of blower fan future development.
Wind power generation gear case is part very crucial in whole machine, plays a part of to transmit power, its matter in whole machine
Amount quality directly affects the security performance and economic performance of blower fan.Due to the particularity of wind-powered electricity generation, gear-box once breaks down, very
Hardly possible disassemble in high-altitude, therefore, as long as breaking down, typically cannot in high-altitude maintenance, can only integral replacing, cause wind-force send out
The use cost of motor remains high.And bearing is used as the critical component in wind turbine gearbox, in recent years it is commonly found that outside bearing
There is relative slip in circle and bearing block.
The content of the invention
Present invention aim at：For wind turbine gearbox axis bearing outer-ring and bearing block by interference fit to machining accuracy
A series of problems, such as having high demands, and relative slip easily occur in use, there is provided a kind of new wind turbine gearbox middle (center) bearing it is spacing
New construction.
A kind of spacing new construction of wind turbine gearbox middle (center) bearing that the object of the invention is realized in, including bearing and bearing
Seat, its feature：Hold and be provided between the outer ring of axle and bearing block a keyway corresponding with key, bearing outer ring and bearing block pass through key
Stop is positioned.
In the present invention：Described key is fixedly installed on bearing block, and the outer ring of bearing is provided with keyway corresponding with key.
In the present invention：Described key is fixedly installed on the outer ring of bearing, and bearing block is provided with keyway corresponding with key.
In the present invention：Described key is placed in and holds between the outer ring of axle and bearing block after corresponding keyway, by with bearing
The pressing plate or pressure ring of seat connection is spacing.
In the present invention：Described pressure ring is end cap or transparent cover.
It is an advantage of the current invention that：Be provided between the outer ring of axle and bearing block a keyway corresponding with key, axle due to holding
Bearing outer-ring and bearing block are positioned by key stop, have effectively prevented the failure risk that relative slip band comes.The present invention is provided key
Various limit methods, or be solidified as a whole with bearing outer ring, or be solidified as a whole with bearing block, or it is by pressing plate or pressure ring spacing.

Specific embodiment
Accompanying drawing restrictively discloses the concrete structure of the embodiment of the present invention, and the present invention is done further below in conjunction with the accompanying drawings
Ground description.
Can be seen that the present invention with reference to Fig. 1, Fig. 2 includes bearing 3 and bearing block 1, holds between the outer ring of axle 3 and bearing block 1
It is provided with one to position by the stop of key 2 with the corresponding keyway of key 2, the outer ring of bearing 3 and bearing block 1（As shown in Figure 2）.Described key
2 are placed between the outer ring and bearing block 1 for holding axle 3 after corresponding keyway, by the pressing plate 4 being connected with bearing block 1（As shown in Figure 1）
Or pressure ring is spacing.In the present embodiment, what described pressing plate 4 was selected is transparent cover, it is also possible to select end cap.
When being embodied as, described key 2 can also be fixedly installed on bearing block 1, and the outer ring of bearing 3 is provided with and 2 pairs, key
The keyway answered.Or key 2 is fixedly installed on bearing block 1, the outer ring of bearing 3 is provided with corresponding keyway.
