Abstract
The utility model provides a kind of new composite structure wind power yawing gear ring, with the technical barrier in solving to install and repairing.To realize object above, the utility model uses following technical scheme：(1) (2) novel gear ring combined by split gear ring with integral brake disc；(2) split gear ring is six sections of Split type structures；Split gear ring (2) with brake disc (1) between with concavo-convex locating surface, positioned by concavo-convex locating surface, (3) fixation tightened by attachment bolt.The utility model has the following advantages：Gear ring local damage only need to change split part without integral replacing part；Gear ring uses Split type structure, can be combined using the ring of different cross section size according to the features of shape of product, raw material are integrally substantial saving in, while greatly reducing manufacturing cost；Brake disc is equivalent to sliding bearing, and moment of friction is stable, and rigidity is good；Small is impacted to yaw system, it is low with respect to accident rate；Reliability is high.
Description
Technical field
The utility model belongs to wind power equipment yaw system parts, and in particular to a kind of new composite structure wind power yawing
Gear ring.
Background technology
Yawing gear ring is the key components and parts in wind power equipment yaw system, and it functions as large-scale bearing.It
Positioned at cabin seat bottom, lower end is connected and fixed by bolt with tower, and top supports whole cabin mechanism by sliding surface, surrounding
External diameter tooth is meshed with four yawing reducer output gears, by the driving for motor of going off course, and drives cabin mechanism integrally to delay
Slow rotation, to reach the purpose of adjustment wind turbine wheel hub Windward angle.Because its installation site is special, repair in use tired
Difficult, replacement cost is high, so the accuracy of manufacture and quality to the part suffer from higher requirement.
Engine rooms of wind power generators subjects huge axial force, radial load and tilting moment at work, in yaw maneuver
Middle load is big, and resistance is big, and inertia is big, and impact is big；The problem of regular generation is go off course dumb, card oar, gear tooth breakage.
Wind driven generator yaw bearing is generally using ball-type race bearing or overall gear ring (sliding bearing) structure, Gear Root
Portion's load is big, once occurring crackle causes broken teeth, raceway or component are damaged, can not all repaired, it is necessary to change whole gear ring
Part or a whole set of bearing maintenance；Maintenance difficulty is big, high equivalent to installation, expense again；Meanwhile, the gear ring of some polymorphic structures
Part is irregular, and assembling height is high, in process, causes the huge waste of raw material.
The content of the invention
The utility model provides a kind of new composite structure wind power yawing gear ring, to solve above-mentioned technical barrier.To realize
Object above, the utility model uses following technical scheme：
(1) (2) novel gear ring combined by split gear ring with integral brake disc；(2) split gear ring is six sections of Split type structures；
Split gear ring (2) with brake disc (1) between with concavo-convex locating surface, positioned by concavo-convex locating surface, (3) fixation tightened by attachment bolt.
The utility model has the following advantages：
Gear ring local damage only need to change split part without integral replacing part；
1. gear ring uses Split type structure, can be combined according to the features of shape of product using the ring of different cross section size, whole
Body substantial saving in raw material, while greatly reducing manufacturing cost；
2. brake disc is equivalent to sliding bearing, and moment of friction is stable, and rigidity is good；
3. small is impacted to yaw system, it is low with respect to accident rate；
4. reliability is high；
Brief description of the drawings
Fig. 1 is new composite structure wind power yawing gear ring axial cross section sectional view,
Icon explanation：Brake disc 1, split gear ring 2, attachment bolt 3.
Embodiment
Below in conjunction with the accompanying drawings 1 and specific embodiment the utility model is described in further detail.
New composite structure wind power yawing gear ring uses gear ring and brake disc combining structure,
Gear ring material is 42CrMo4, and brake disk material is S355J2；Gear ring is Split type structure, and brake disc is overall structure.
Split gear ring 2 is worked into finished product, is then cut into six sections uniformly, then pass through brake disc 1 and the faying face of split gear ring 2
Between concavo-convex locating surface positioning be assemblied together, the fit clearance between concavo-convex locating surface is minimum, no more than 0.06mm, it is ensured that weight
New clothes do not influence the precision index and performance of product with the deformation of rear gear ring, adjust and are used again after public law linear dimension between each section of tooth
Attachment bolt 3 is tightened, and can be just installed in wind power yawing system and be used after a whole set of anti-corrosion.
Claims (2)
1. new composite structure wind power yawing gear ring, it is characterised in that：(2) (1) combined with integral brake disc by split gear ring；
Split gear ring (2) with brake disc (1) between with concavo-convex locating surface, positioned by concavo-convex locating surface, (3) fixation tightened by attachment bolt.
2. new composite structure wind power yawing gear ring according to claim 1, it is characterised in that：(2) the split gear ring is six
Section Split type structure.
