Abstract
The utility model relates to a transmission shaft structure, in particular to a big torque flexible transmission shaft for wind generating set, belonging to the machinery field. The transmission shaft is composed of three shaft connected by a flexible connecting piece, each shaft is composed of two shaft heads, a hollow shaft and a welding flange; wherein the shaft head is respectively fixedly connected with the welding flange by the hollow shaft, and upper and lower shafts are respectively connected with an intermediate shaft by the flexible connecting piece. The hollow shaft and the shaft head are welded into a whole. The utility model has the characteristics of big transmission torque, light weight, high strength, convenient processing, transportation and wild installation.
Description
Technical field
The utility model relates to a kind of transmission shaft structure, particularly with a kind of high pulling torque flexible drive axle that is used for wind power generating set, belongs to mechanical field.
Background technique
China is energy consumption big country.Since the reform and opening-up, the Chinese national economy fast development, increasing to the demand of the energy, the contradiction between energy consumption and the energy resource supply becomes increasingly conspicuous, even has arrived the degree of restriction Chinese national economy development.In order to tackle this contradiction, China has passed through " People's Republic of China's renewable energy sources method " in 2005, list non-fossil energies such as wind energy, solar energy, water energy, biomass energy, geothermal power, ocean energy in renewable energy sources in the lump, become the pioneer field of energy development.Country advocates and encourages economic entity under all types of ownership to participate in the development and use of renewable energy sources, protects the renewable energy sources opening according to law and utilizes this legitimate interests.Utilizing of wind energy is more prevalent, and as the critical piece of wind-driven generator, transmission shaft plays important function.Shortcomings such as the transmission axle body is long, can poor reliability occur, rigidity is poor, and is in use impaired easily.
Summary of the invention
The utility model provides a kind of high pulling torque flexible drive axle that is used for the vertical wind driven generator group for solving the problems referred to above of prior art, and the utility model transmitting torque is big, and is in light weight, and the intensity height is convenient to characteristics such as processing, transportation and open-air installation.
For realizing above-mentioned technique effect, the utility model adopts following technological scheme:
A kind of high pulling torque flexible drive axle that is used for the vertical wind driven generator group, described transmission shaft is connected and composed by flexible connecting member by three axles, it is characterized in that: every axle is made of two spindle noses, hollow shaft and welded flanges, described spindle nose is fixedlyed connected with welded flange by hollow shaft respectively, and upper and lower axle is connected with jack shaft by flexible connecting member respectively.
Flexibly connect is to constitute by adding elastic element between two intermeshing rigidity axle heads.Rigid engagement guarantees to transmit enough moments of torsion, and elastic element can reduce the impact that positive drive produces again, thereby makes moment of torsion be able to smooth transfer, has prolonged the whole life-span.
This transmission shaft links together three axles by flexible unit.Wherein the root axle is divided into two sections by the centre again, and welding flange links together with bolt, is convenient to processing, transportation and installation.On the basis of conventional design,, guaranteeing that under the preceding topic that moment of torsion transmits, intermediate section adopts hollow structure, with the diameter and the thick minimum that drops to of arm of axle by computer optimization design and modeling analysis in kind.Thereby reduced the weight of axle self.Spindle nose adopts solid construction, is convenient to processing step and cooperates with bearing and be used for installing and locating.Intermediate hollow section and spindle nose are welded as integral body.
This transmitting torque is big, and is in light weight, and the intensity height is convenient to processing, transportation and open-air the installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic representation that concerns between flexible connecting member and elastic element.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.The utility model is a kind of high pulling torque flexible drive axle that is used for wind power generating set, described transmission shaft is connected and composed by flexible connecting member 1 by three axles, every axle is made of two spindle noses 2, hollow shaft 3 and welded flange 4, described spindle nose 2 is fixedlyed connected with welded flange 4 by hollow shaft 3 respectively, and the axle at two ends is connected with jack shaft by flexible connecting member 1 respectively.
Flexible connecting member 1 is to constitute by adding elastic element 5 between two intermeshing rigidity axle heads.Rigid engagement guarantees to transmit enough moments of torsion, and elastic element 5 can reduce the impact that positive drive produces again, thereby makes moment of torsion be able to smooth transfer, has prolonged the whole life-span.Be welded as integral body between hollow shaft 3 and the spindle nose 2.
Wherein elastic element 5 is rubber-like plastics or other elastic polymeric materials.
This transmission shaft links together three axles by flexible unit.Wherein every axle is divided into two sections by the centre again, and welding flange links together with bolt, is convenient to processing, transportation and installation.On the basis of conventional design,, guaranteeing that under the preceding topic that moment of torsion transmits, intermediate section adopts hollow structure, with the diameter and the thick minimum that drops to of arm of axle by computer optimization design and modeling analysis in kind.Thereby reduced the weight of axle self.Spindle nose 2 adopts solid constructions, is convenient to processing step and cooperates with bearing and be used for installing and locating.Be welded as integral body between intermediate hollow axle 3 and the spindle nose 2.This transmitting torque is big, and is in light weight, and the intensity height is convenient to processing, transportation and open-air the installation.
