Abstract

The invention discloses a kind of wind-power electricity generation split wheel hub, including wheel hub split, three wheel hub splits are spliced into a wheel hub entirety, each wheel hub split both ends are respectively equipped with semicircular cylinder end, the angle at two semicircular cylinder ends in each wheel hub split is 120 °, and the semicircular cylinder end matching of two neighboring wheel hub split is connected into a cylinder.The advantage of the invention is that:By the way of split, the technology difficulty of single-piece is reduced, so as to reduce the percent defective of wheel hub, while convenient transportation;Stretching semicircular cylinder end matching is connected into cylinder and replaces wind power generation blade blade root section at wheel hub split, reduces the quality risk of blade root implantation;It is furnished with reinforcement between the semicircular cylinder end of wheel hub split, there is more preferable structural strength.

Description

A kind of wind-power electricity generation split wheel hub
Technical field
The present invention relates to a kind of wind power generation hub, more particularly to a kind of wind-power electricity generation split wheel hub.
Background technology
Wind power hub is a very important part in wind power generating set, in blower fan structure, wheel hub connection main shaft With blade, effect is that wind-force is passed into main shaft and gear-box to the used load of blade.With the maximization of Wind turbines Development trend, the volume of wheel hub is also increasing with quality, reaches more than 10t.Therefore, large-scale wheel hub is wanted to casting technique More and more higher is sought, it is also more next big to the radius of machining of machining apparatus.In order to solve problem above, design customization is generally required Equipment produce large-scale wheel hub, virtually add manufacturing cost.In addition, with the increase of rotor diameter, wind-force hair The length of electric blade is also increasingly longer, and corresponding blade root thickness is also increasingly thicker, because the making material of wind blade is mostly Glass fiber material, and too thick glass fibre infusion process difficulty is very big, easily fills impermeable, produces quality problems, therefore leaf Root position is replaced with steel can be better.
The content of the invention
It is an object of the invention to solve problems of the prior art, there is provided a kind of wind-power electricity generation split wheel hub, have Effect reduces single-piece volume, reduces technology difficulty and reduces machining apparatus processing diameter simultaneously, so as to reduce manufacturing cost.
Technique according to the invention scheme, the wind-power electricity generation split wheel hub, including wheel hub split, three wheel hubs point Body is spliced into a wheel hub entirety, and each wheel hub split both ends are respectively equipped with semicircular cylinder end, and two and half in each wheel hub split The angle of cylinder end is 120 °, and the semicircular cylinder end matching of two neighboring wheel hub split is connected into a cylinder.
Further, it is provided with reinforcement between two semicircular cylinder ends of the wheel hub split.
The present invention has advantages below compared with prior art:
Due to by the way of split, reducing the technology difficulty of single-piece, so as to reduce the percent defective of wheel hub;
Due to by the way of split, convenient transportation;
Wind power generation blade blade root section is replaced 3. stretching out semicircular cylinder end matching at wheel hub split and being connected into cylinder, reduces blade root filling Defeated quality risk;
4. being furnished with reinforcement between the semicircular cylinder end of wheel hub split, there is more preferable structural strength.
Brief description of the drawings

Fig. 2 is the single wheel hub Split type structure schematic diagram of the present invention.
Fig. 3 is the present invention and main shaft connection structure schematic diagram.
Description of reference numerals:1st, wheel hub split;11st, semicircular cylinder end;12nd, reinforcement;2nd, pitch variable bearings;3rd, wind electricity blade; 4th, main shaft;ɑ:The angle at two semicircular cylinder ends.
Embodiment
With reference to specific embodiments and the drawings, the invention will be further described.
As Figure 1-3:A kind of wind-power electricity generation split wheel hub, including wheel hub split 1, three wheel hub splits 1 pass through positioning Pin etc. is spliced into a wheel hub entirety, and each both ends of wheel hub split 1 are respectively equipped with semicircular cylinder end 11, in each wheel hub split 1 The angle ɑ at two semicircular cylinder ends 11 is 120 °, and the semicircular cylinder end 11 of two neighboring wheel hub split 1 is spliced into a cylinder.Every Reinforcement 12 is additionally provided between two semicircular cylinder ends 11 of individual wheel hub split 1, improves structural strength.
Operation principle:The semicircular cylinder end 11 of two neighboring wheel hub split 1 is spliced into a cylinder, passes through with pitch variable bearings 2 Bolt connection, pitch variable bearings 2 form overall flange face and master with wind electricity blade 3 also by bolt connection, 3 wheel hub splits 1 Axle 4 is bolted, and forms total.When wind load is acted on wind electricity blade 3, wind electricity blade 3 bears wind load while produced Lively power, and split wheel hub of the present invention is imparted power to, split wheel hub imparts power to main shaft 4 again.
The present invention is used as pitch variable bearings and the force transferring part of main shaft, bears complicated alternate load, by the way of split, The technology difficulty of single-piece is reduced, so as to reduce the percent defective of wheel hub, while is transported more convenient;Half is stretched out at wheel hub split Cylinder end is spliced into cylinder and replaces wind power generation blade blade root section, reduces the quality risk of blade root implantation;Wheel hub split Semicircular cylinder end between be furnished with reinforcement, there is more preferable structural strength.
