Description
Technical field
The utility model relates to the technical field of wind generating set yaw system, refers in particular to a kind of Seal cage structure of wind generating set yaw system.
Background technique
Known in the industry, what existing wind generating set yaw system adopted mostly is a kind of open architecture, the output gear that the ring gear of driftage bearing and driftage drive is directly exposed to be safeguarded in space, because this is rotary component, when safeguarding, operator have potential safety hazard, simultaneously go off course grease in bearing and the grease of the flank of tooth can directly drip on maintenance platform, causes maintenance platform to pollute.In addition, the flank of tooth exposes, and dirt impurity easily pollutes the flank of tooth, causes the accuracy of mesh to decline, and affects working life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of compact structure is reliable, housekeeping operation is convenient, reduce maintenance cost, guarantee the Seal cage structure of the wind generating set yaw system of the accuracy of mesh.
For achieving the above object, technological scheme provided by the utility model is: a kind of Seal cage structure of wind generating set yaw system, comprise driftage supporting structure and internal gear type driftage bearing, wherein, described driftage supporting structure is outer peripheral surface open type circular shell structure, its periphery is formed with the annular groove circumferentially extending along it, the shape size of its intermediate throughholes and the frame of wind power generating set are suitable, on one side, can fill off-course brake, on its another side, can fill driftage and drive, and be shaped to the support platform of hydraulic station; Described internal gear type yaw axis is honoured in the annular groove that should be loaded on described driftage supporting structure, its shape size and this annular groove are suitable, and and this annular groove between be formed with the accommodating cavity of the output gear that ring gear and driftage for accommodating internal gear type driftage bearing drive, and described accommodating cavity adopts mechanical seal, becomes an airtight cavity.
One side of described driftage supporting structure dress off-course brake disposes the shape size driftage support ring suitable with it, on this driftage support ring, is inlaid with seal ring; Described mechanical seal be the supporting structure of going off course be rotating ring, with the stationary ring that is combined as of go off course support ring and seal ring.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
1, make the whole driftage bearing flank of tooth, the driftage driver output flank of tooth in airtight cavity, can avoid dirt, the contaminating impurity driftage bearing flank of tooth and the driftage driver output flank of tooth, and then can guarantee the accuracy of mesh, improve the engagement life-span, reduce maintenance cost;
2, can avoid grease to flow on the brake disc of off-course brake, affect braking effect;
3, the support platform of hydraulic station, the support of maintenance platform can doublely be done in the side that the driftage of driftage supporting structure dress drives.
Accompanying drawing explanation
Fig. 1 is the structural representation of wind generating set yaw system.
Fig. 2 is partial sectional view of the present utility model.
Fig. 3 is the A partial enlarged drawing of Fig. 2.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Referring to shown in Fig. 1 to Fig. 3, the Seal cage structure of the wind generating set yaw system described in the present embodiment, comprise driftage supporting structure 1 and internal gear type driftage bearing 2, wherein, described driftage supporting structure 1 is outer peripheral surface open type circular shell structure, its periphery is formed with the annular groove circumferentially extending along it, the shape size of its intermediate throughholes and the frame of wind power generating set are suitable, on one side, can fill off-course brake 3, on its another side, can fill driftage and drive 4, and be shaped to the support platform of hydraulic station, the support of maintenance platform, described internal gear type driftage bearing 2 correspondences are loaded in the annular groove of described driftage supporting structure 1, its shape size and this annular groove are suitable, and and this annular groove between be formed with the accommodating cavity 5 that drives 4 output gear for the ring gear 201 of accommodating internal gear type driftage bearing 2 and driftage, and described accommodating cavity 5 adopts mechanical seal, become an airtight cavity, design makes the whole driftage bearing flank of tooth like this, the driftage driver output flank of tooth is in this airtight cavity, thereby can avoid dirt, the contaminating impurity driftage bearing flank of tooth and the driftage driver output flank of tooth, and then can guarantee the accuracy of mesh, improve the engagement life-span, reduce maintenance cost.
In addition, for realizing the mechanical seal of above-mentioned accommodating cavity 5, one side of the supporting structure of going off course described in the present embodiment 1 dress off-course brake 3 disposes the shape size driftage support ring 6 suitable with it, on this driftage support ring 6, be inlaid with seal ring 7, described driftage support ring 6 fits with the inner ring of internal gear type driftage bearing 2, simultaneously, brake disc 301 correspondences of described off-course brake 3 are located at the opposite side of these driftage support ring 6 relative inner rings, and fit with this driftage support ring 6, described in the present embodiment mechanical seal be the supporting structure 1 of going off course be rotating ring, the stationary ring that is combined as with driftage support ring 6 and seal ring 7, special like this Seal Design can avoid grease to flow on the brake disc of off-course brake 3, affect braking effect.
In sum, after adopting above scheme, by the unique design of this Seal cage structure, can effectively avoid dirt, the contaminating impurity driftage bearing flank of tooth and the driftage driver output flank of tooth, affect the accuracy of mesh and life-span, and effectively avoid grease to flow on the brake disc of off-course brake 3, affect braking effect.This compared to existing technology, the utility model has solved many drawbacks that prior art exists well, when improving engagement life-span and component working life, has reduced maintenance cost, and has facilitated operator's maintenance, safety reliability is high, is worthy to be popularized.
