Description
Technical field
The utility model relates to a kind of wind power plant, relates in particular to a kind of wind power generating set---high speed shaft protective gear of double-fed unit or half direct-driving type unit that is mainly used in the band gear box structure.
Background technique
Wind-power electricity generation is that wind energy transformation is mechanical energy, mechanical energy is converted into the mechanical device of electric energy again.The development of wind generating technology was experienced from the technology maturation stage up till now initial starting stage, the main design concept that adopts " horizontal axis, three blades, upwind " can be divided into double-fed wind, direct-driving type, half direct-driving type (or hybrid type) on this basis again.
The wind power generating set brake is mainly used in safety system, high speed shaft brake motion speed height, brake load is big, poor stability, brake can cause brake disc and brake bush sharply to wear and tear under the state of emergency, under the extreme condition even the situation of brake disc or brake bush fracture occurs, coupling is applied to double-fed and partly directly drives unit, in order to transmit from wind wheel through speed increaser rotating speed that amplifies and the torque that reduces, impulsive load during braking state and the oscillating load of speed increaser, when satisfying system vibration axially, radially, angle changes, i.e. shock resistance and tired requirement.In the running of wind power generating set, high speed shaft and coupling rated speed are up to 1800rpm, and for preventing splashing of brake disc and brake wear material, the instrument of preventing falls and personnel's touching, and protection unit and personal security need externally be provided with safety cover.
Traditional high speed shaft safety cover is usually designed to overall structure, has complex structure, installing/dismounting poor operability, is unfavorable for observing the shortcoming of the state of brake disc, break and coupling.
The model utility content
The purpose of this utility model is to provide a kind of wind-driven generator high speed shaft protective gear, and it has the advantages that to be convenient to during simple in structure, safe and reliable, easy accessibility and the unit operation the examination and maintenance of coupling, brake disc and high speed shaft break.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of wind-driven generator high speed shaft protective gear; it comprises brake disc safety cover and coupling safety cover that independent split is provided with; described brake disc safety cover is arranged at the top of high speed shaft brake disc, and described coupling safety cover is arranged at the coupling top between gear-box and generator.
Especially; described brake disc safety cover is welded by two blocks of sheet metals, and the cover body part is bent into arcuate structure by sheet metal, and its two ends all are extended with a junction; offer mounting hole on the described joint, be fixed on by support, fixing bolt on the brake of gear housing body.
Especially; described coupling safety cover becomes U type structure by the sheet metal Bending Processing; covered the rotating part of coupling; offer several through holes on it; and carry out flange in its Zhi Bi lower edge and form assembly department; offer fixed hole on the described assembly department, the coupling safety cover is fixed on the framework platform by fixed hole.
The beneficial effects of the utility model are:
1, simple in structure, easily manufactured;
2, adopt split-type structural to be convenient to dismounting, make things convenient for the maintenance of associated components;
3, be convenient to observe the running state of protected mechanism;
4, safe and reliable, effectively high-speed component and external isolation are opened, and in light weight, reduce the harm that vibrations bring.
