The utility model can make use of natural wind for generating electricity, and has the advantages of energy saving, no pollution, reasonable structure, small volume, high efficiency, large bearing force, steady working, low electricity generation cost and good economy.
Description
One, technical field:
The utility model relates to a kind of gear-box, especially planet driving of parallel axes wind power generation gear case.
Two, background technique:
At present, the generation mode that everybody was familiar with has hydroelectric power and thermal power generation, and the cost of these two kinds of generation modes is all very high, thermal power generation not only will consume a large amount of coal resources, and thermal power generation is quite serious to environment and pollution of atmosphere, and its shortcoming is to cause shortage of resources, worsens ecotope.Though hydroelectric power is pollution-free, but the total installation of generating capacity of small-sized hydroelectric power plant is little, generated energy is little, can not satisfy the increasing electricity consumption needs of people, though large-scale hydroelectric power plant total installation of generating capacity is big, but equipment cost height, construction period is long, short in global energy and ecotope goes from bad to worse today, many countries are all developing wind-power electricity generation as the important energy policy, the Chinese government also pays much attention to the development of wind-power electricity generation, but owing to start late, makes present China also not possess the ability that designs the production Large-scale Wind Turbines voluntarily, in order to utilize the wind resource of China's abundant, government is spending the external wind power plant of a large amount of foreign exchange imports always, has so both consumed fund, is unfavorable for developing the national industry of China again.
Two, summary of the invention:
The purpose of this utility model provides a kind of planet driving of parallel axes wind power generation gear case, utilizes the wind energy converting electrical energy, and the existing generation technology energy consumption of solution is big, and environmental pollution is serious, cost of electricity-generating height, less economical problem.
Concrete scheme of the present utility model is: the A. input shaft is coaxial with the sun gear that is positioned at gear-box; B. be connected with planet carrier on the input shaft before stretching in the casing, planet carrier is provided with planet wheel, planet wheel often meshes with sun gear and gear ring simultaneously, its parallel axes is in input shaft, the no increment of sun gear connects axle, the gear on the axle and the shaftgear of gear shaft often mesh, and the gear on the gear shaft often meshes with the shaftgear of output shaft again; C. output shaft and gear shaft lay respectively at the input shaft both sides, and their axis is parallel to each other, and one of output shaft is stretched out rear box.
Adopt such scheme, can utilize the natural wind generating, both energy saving, pollution-free again, it is rational in infrastructure, advanced technology, volume is little, the efficient height, bearing capacity is big, stable working, cost of electricity-generating is low, good economy performance.
Three, description of drawings:
Fig. 1 is a transmission schematic representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Four, embodiment:
Please see Figure 1, Fig. 2, the utility model mainly is made up of input shaft 1, planet carrier 2, planet wheel 3, gear ring 4, sun gear 5, gear 6, gear shaft 7, gear 8, output shaft 9, preceding casing 10, middle casing 12, rear box 13, axle 14 etc., and its structure characteristic is: A. input shaft 1 is coaxial with the sun gear 5 that is positioned at gear-box; B. be connected with planet carrier 2 on the input shaft 1 before stretching in the casing 10, planet carrier 2 is provided with planet wheel 3, planet wheel 3 often meshes with sun gear 5 and gear ring 4 simultaneously, its parallel axes is in input shaft 1, the no increment of sun gear 5 connects axle 14, gear 6 on the axle 14 often meshes with the shaftgear of gear shaft 7, and the gear 8 on the gear shaft 7 often meshes with the shaftgear of output shaft 9 again; C. output shaft 9 and gear shaft 7 lay respectively at input shaft 1 both sides, and their axis is parallel to each other, and one of output shaft 9 is stretched out rear box 13.
As shown in Figure 2: gear-box is formed through Bolt Connection by preceding casing 10, middle casing 12 and rear box 13.
Also can learn from Fig. 2: gear ring 4 by casing 10 before being bolted to and between the casing 12.
As can be seen from Figure 2: gear 6, gear shaft 7, gear 8 and output shaft gear 9 all are helical gears.
Working principle of the present utility model is: this gear-box is installed in the wind-driven generator tower frame, wind wheel on the pylon links together through bolt and main shaft, the wind wheel main shaft is connected with the input shaft 1 of this gear-box again, wind wheel rotates under the wind-force effect, driving the wind wheel main shaft rotates, the wind wheel main shaft drives input shaft 1 again and rotates, input shaft 1 drives planet carrier 2, planet carrier 2 drives planet wheel 3 and rotates, and planet wheel 3 drives sun gear 5 again, and sun gear 5 drives axle 4 and rotates, gear 6 driven gear axles 7 on the axle 4 rotate, gear 8 on the gear shaft 7 drives output shaft 9 and rotates, and output shaft 9 is connected with generator, thereby drives the generator set generating.
