Description
Technical field
The utility model relates to a kind of support device of gear-box, is specifically related to a kind of megawatt-level wind gear-box support device.
Background technique
Wind energy is the most representative a kind of in the renewable energy sources, and it is to the protection environment and keep the ecological balance, and reduces conventional energy resource is relied on and to improve energy resource structure significant.The wind-powered electricity generation working principle of said set is that blade is converted to kinetic energy with wind energy, is delivered to generator by transmission system, and generator produces electric energy and is input to electrical network.Wherein the reliability of transmission system just seems particularly important.In the wind-powered electricity generation compressor emergency shutdown case, the fault of Transmitted chains accounts for significant proportion.So the more reliable work of transmission system is the important measures that prolong the wind-powered electricity generation unit generation time.
At present, the support pattern of wind-powered electricity generation unit transmission system is that a bearing is respectively arranged in the main shaft front end and back end, and the elastic support that the gear-box both sides are made by rubber material is bonded on the mainframe.
Because three strong points are arranged on axial drive path, thereby and bigger than normal formation of rigidity that move up and down of elastic support cross constraint.Reasons such as the radially alignment error of transmission system, wind wheel stand under load can cause main shaft with respect to gear-box primary planet carrier decentraction, make the input shaft of gear-box produce harmful moment of flexure, and then making bearing in the gear-box and gear produce unbalance loading, to cause the gear-box working state abominable, reduced the reliability of gear-box.
The model utility content
In order to overcome the harmful radially deficiency of moment of flexure of gear-box primary planet carrier that existing gear-box elastic support is brought, the purpose of this utility model is: a kind of megawatt-level wind gear-box support device is provided, this support device can significantly reduce harmful moment of flexure of input shaft, strengthen the reliability of gear-box, improve working life.And simple in structure, be easy to safeguard.
The technological scheme that its technical problem that solves the utility model adopts is as follows:
A kind of megawatt-level wind gear-box support device, it comprises a toggle, a transverse link, two transverse link arms, a longitudinal rod, two longitudinal rod arms and two bases; Described toggle is fixed on the gear-box, respectively is provided with one on toggle front end both sides and connects projection, and each respectively has a through hole in the middle of connecting projection, and these two lead to the hole site are concentric, and transverse link is located in the through hole of these two connection projections; Respectively be provided with a transverse link arm at the two ends of transverse link, these two equal lateral arrangement of transverse link arm also respectively have two holes thereon, in the hole of back, wear the end of transverse link, hole in front is a through hole, these two lead to the hole site are concentric, and longitudinal rod is located in the through hole of these two transverse link arms; Respectively be provided with a longitudinal rod arm at the two ends of longitudinal rod, these two longitudinal rod arms are all vertically arranged and are respectively had two holes thereon, wear the end of longitudinal rod in the hole on top, and following hole is connected with base by joint pin.
Before and after the bottom of two bases a damping elastic support is housed respectively, joint pin is inserted in the through hole of base and damping elastic support, and base is fixedlyed connected with the mainframe of wind-powered electricity generation unit by this damping elastic support.
Because in the utility model gear-box support device, adopt the slip between transverse link and the toggle to be rotationally connected, make the contact surface of transverse link and toggle through hole carry out slide relative, realize that transverse link can relatively rotate around the through-bore axis of toggle.Also be rotationally connected between same longitudinal rod and the transverse link arm, make the contact surface of longitudinal rod and transverse link arm through hole carry out slide relative, realize that longitudinal rod can relatively rotate around the through-bore axis of transverse link arm for sliding.The longitudinal rod arm is fixedlyed connected with the mainframe of wind-powered electricity generation unit by base.When the wind-powered electricity generation unit operation, power passes to gear-box to moment of torsion by input shaft, and the external torque of its generation acts on the mainframe by push and pull system, and the toggle of gear-box need bear the external torque of gear-box.Owing to reasons such as the radially alignment error of transmission system, wind wheel stand under load can cause main shaft with respect to gear-box primary planet carrier decentraction, thereby main shaft has the moment of flexure effect with respect to the gear-box primary planet carrier, the moment that this effect produces makes the connecting rod in the utility model gear-box support device be rotated by hinge, decontroled the up and down degrees of freedom of gear-box, to adapt to the decentraction effect between main shaft and the gear-box primary planet carrier.Eliminate the constraint of crossing of Transmitted chains, harmful moment of flexure that the gear-box primary planet carrier is born significantly reduces.
Therefore compared with prior art, the beneficial effects of the utility model are:
1, can significantly reduce harmful moment of flexure of input shaft, optimize the stress of gear-box, improve the reliability of gear-box, prolong the working life of gear-box.
2, the utility model gear-box support device structure is simple, is easy to make, installs and maintenance.
