Description
Technical field
The present invention relates to wind power generation field, more particularly to a kind of blade installation structure of low-resistance wind-driven generator.
Background technology
Wind-driven generator is often located in unmeasured vastness depopulated zone, so maintenance very trouble, and wind motor
At every moment in running order, in the case where the sun is exposed to the sun, lubricating oil, which is very easy to go bad, causes blade rotary resistance to become big.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of can keep the wind-force of lower resistance to send out for a long time in the presence of a harsh environment
The blade installation structure of motor.
The present invention solve its technical problem solution be：
A kind of blade installation structure of low-resistance wind-driven generator, including the axle sleeve with inner chamber, axle sleeve are provided with rotating shaft, turn
One end of axle is provided with air blade, and the other end of rotating shaft is provided with finder, and the inner chamber is provided with deep groove ball bearing, multiple lubrication groups
Part, the lubrication assembly include the graphite block abutted with rotating shaft, compression spring are provided between graphite block and the internal chamber wall of axle sleeve, turn
Axle is connected with deep groove ball bearing, and lubrication assembly is located at the side of deep groove ball bearing.
As the further improvement of such scheme, the finder is conical thin wall component, the top of finder and rotating shaft
End face connection.
As the further improvement of such scheme, one end of compression spring is fixedly connected with the cavity wall of inner chamber, compression spring
Free state length be less than the distance of rotating shaft outer wall and inner chamber cavity wall.
The beneficial effects of the invention are as follows：A kind of blade installation structure of low-resistance wind-driven generator, including the axle with inner chamber
Set, axle sleeve are provided with rotating shaft, and one end of rotating shaft is provided with air blade, and the other end of rotating shaft is provided with finder, and the inner chamber is provided with
Deep groove ball bearing, multiple lubrication assemblies, the lubrication assembly include the inner chamber of the graphite block abutted with rotating shaft, graphite block and axle sleeve
Compression spring is provided between wall, rotating shaft is connected with deep groove ball bearing, and lubrication assembly is located at the side of deep groove ball bearing.Turn in rotating shaft
In dynamic process, graphite block can rub with rotating shaft, and so as to produce graphite powder, and these graphite powders can enter deep-groove ball axle
Hold, so as to play a part of lubrication to deep groove ball bearing, and the setting of finder, air blade face wind direction can be allowed, improve hair
Electrical efficiency.The present invention is used for wind motor.
Brief description of the drawings
