Specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention specifically provides two embodiments: one kind is applied to the rotation of yaw 5-i outer ring and one kind during driftage The wind power generating set of yaw 5-ii inner ring rotation.
Referring to the drawings 1, during a kind of driftage, it is applied to the wind power generating set of yaw 5-i outer ring rotation, its driftage is driven Dynamic system includes: cabin 3, tower 9, yaw motor 4, Yaw gearbox 1, yaw 5-i and brake disc 6-i.Described braking Disk 6-i is located between tower 9 upper surface and yaw 5-i lower surface, is connected with yaw 5-i inner ring.Preferably, described Yaw 5 is using 4 points of angular contact ball bearings of biserial of negative clearance pretension.Described Yaw gearbox 1 with inclined positioned at its top Avionics machine 4 is fixing, and is provided with output pinion 7 in bottom.It is provided with yaw gear 10, tooth of going off course inside described brake disc 6-i Wheel 10 is meshed together with the output pinion 7 of multiple Yaw gearbox 1 bottoms.Preferably, described Yaw gearbox 1 passes through spiral shell Bolt 8 is fixed in cabin 3.By driving force or brake force are applied to brake disc 6-i, it is possible to achieve the rotation of cabin 3 and braking. Described yaw 5-i outer ring is fixed on cabin 3 bottom, drives positioned at its bottom when yaw motor 4 passes through Yaw gearbox 1 During output pinion 7 rotation, yaw 5-i inner ring maintains static, and outer ring is rotated with cabin 3, realizes wind power generating set inclined Boat.
With reference to Fig. 2, the wind power generating set of bearing 5-ii inner ring rotation when being applied to driftage during a kind of driftage, its driftage is driven Dynamic system includes cabin 3, tower 9, yaw motor 4, Yaw gearbox 1, yaw 5-ii and brake disc 6-ii.Described braking Disk 6-ii is fixed between tower 9 upper surface and yaw 5-ii lower surface, is connected with yaw 5-ii outer ring.Described inclined Boat gear-box 1 is fixing with the yaw motor 4 positioned at its top, and is provided with output pinion 7 in bottom.In described brake disc 6-ii Side is provided with yaw gear 10, and yaw gear 10 is meshed together with the output pinion 7 of multiple Yaw gearbox 1 bottoms.Institute State yaw 5-ii inner ring and be fixed on cabin 3 bottom, drive positioned at its bottom when yaw motor 4 passes through Yaw gearbox 1 During output pinion 7 rotation, yaw 5 outer ring maintains static, and inner ring is rotated with cabin 3, realizes wind generating set yaw.
Preferably, have groove on brake disc 6 surface, described groove is half moon groove, be up time including concave direction The groove 15- of the groove 15-i of pin setting or counterclockwise setting.No matter wind power generating set is inclined clockwise or counterclockwise Boat, all can wipe the ash bits of single-top liquid braking device 11 and pincers lock formula liquid braking device 12 Friction Disk Surface off, and can collect one Ash bits and hydraulic oil that quantitative brake disc 6 surface is accumulated.
Yaw device also includes brake.As described in Figure 3, including single-top liquid braking device 11 and pincers lock formula hydraulic braking Device 12.Described single-top liquid braking device 11 and pincers lock formula liquid braking device 12 are fixedly mounted in cabin 3, by being applied to system Pressure on Moving plate 6 realizes braking.
Single-top liquid braking device 11 and pincers lock formula liquid braking device 12 brake pressure are provided by hydraulic system, every kind of braking Device can be according to needing to provide low pressure and two kinds of different braking pressure of high pressure.In During yaw, single-top liquid can be selected Pressure 11 dozens of low pressure of brake, pincers 12 dozens of low pressure of lock formula liquid braking device or two kinds of brakes beat low pressure together, can be according to control System needs to select different kinetic force of frictions to maintain the stability of yaw system, effectively optimizes yaw brake process;In system During dynamic, high pressure all beaten by pincers lock formula liquid braking device 12 and single-top liquid braking device 11, can produce sufficiently large quiet rub Wiping power keeps the static required brake force of cabin it is ensured that wind power generating set head will not rock back and forth when generating electricity to meet.Separately Outward, because single-top liquid braking device 11 and pincers lock formula liquid braking device 12 brake pressure are provided by hydraulic system, it is to avoid dish Spring occurs the problems such as elasticity loss, deformation after being run multiple times, and persistently can carry in wind power generating set long-play For stable brake force.
It is provided with pad 2 between the contact surface of described Yaw gearbox 1 and cabin 3 fixation.Long-time in wind power generating set After operation, brake disc 6 surface occurs uneven wear, leads to situations such as driftage abnormal sound, local unbalance loading and brake force deficiency, shadow Ring yawing brake system reliability service.Now it is only necessary to be polished to brake disc 6 surface using polisher or other equipment, Then pass through adjust pad 2 thickness it is ensured that center alignment can complete to repair when output pinion 7 is engaged with brake disc 6 gear. Whole machine need not be fallen down when repairing by brake disc 6, safeguards simple, expense is less, is conducive to keeping brake disc 6 surface essence for a long time Degree is so that wind power generating set being capable of reliability service.
The embodiment of the present invention, by brake disc 6, driving force is indirectly transferred to yaw 5 so that yaw 5 stress Evenly, it is to avoid local unbalance loading, overload impact lead to yaw 5 lasso stand under load and deformation excessive, yaw 5 and partially can be made Boat gear 10 runs more steady.Simultaneously as no gear ring on yaw 5 inner ring or outer ring, improve bearing ring firm Degree, bearing deformation is less, and bearing capacity is more excellent, also will not be in turn because bearing deformation leads to yaw gear to become in engagement process Shape, unbalance loading.Using the present invention can the too small defect of yaw bearing safety coefficient in effectively solving yaw system, significantly improve The wind generating set yaw device life-span.
Present invention additionally comprises a kind of wind power generating set, it includes yaw device, and described yaw device is described above Yaw device.
It is one embodiment of the present invention above, a preferred demonstration example.The scope that the present patent application is claimed It is not only limited in described embodiment.All technical schemes equivalent with the present embodiment belong to protection scope of the present invention.
