The utility model provides an aerogenerator stopper of yawing, including the stopper body, be equipped with a piston hole on the stopper body, be equipped with the piston in the piston hole, the bottom of piston hole is equipped with the inlet port, be equipped with annular seal groove on the lateral wall of piston hole, be equipped with the sealing washer in the seal groove, characterized by: still be equipped with a guide way on the lateral wall of piston hole, the guide way setting at piston hole drill way department, the embedded bush that is equipped with of guide way. The utility model discloses a be equipped with a guide way on the lateral wall of piston hole drill way department, the embedded bush that is equipped with of guide way, bush opening shape can contain certain deformation, strengthens the anti unbalance loading ability of piston like this, and the protection sealing washer is not transversely extrudeed by the piston repeatedly, improves the greasy property of piston side, reduces the coefficient of friction between the inner wall of piston and piston hole, has prolonged the utility model discloses a life.
Description
Technical field
The utility model belongs to technical field of wind power, especially relates to a kind of Yawing brake of aerogenerator.
Background technique
Yawing brake of aerogenerator is the important component part of wind driven generator yaw system, and its Main Function is: when ensureing that wind-driven generator stops going off course, and can not depart from wind direction because blade is passive by wind load.Existing Yawing brake of aerogenerator, many employings are without piston guide bush structure, causing Yawing brake of aerogenerator piston, to bear unbalance loading ability weak, seal ring is repeatedly extruded by piston transverse force and is out of shape, the easily scratch mutually of the sidewall of brake plunger and piston hole, reduce piston seal performance, this lets out causing in the oil pressure of break, piston is occurred problems such as pressurize is unable, the dwell time is short, brake slip, replacing Sealing are frequent.Yawing brake of aerogenerator also can because sealability is unreliable reduction of service life, affect the safe operation of whole wind-driven generator.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of and bears the strong Yawing brake of aerogenerator of braking unbalance loading ability, and it also has good sealing effect, dwell pressure is high, the dwell time is long advantage.
The technical solution adopted in the utility model is: comprise break body, and break body is provided with a piston hole, is provided with piston in piston hole, and the bottom of piston hole is provided with oil inlet hole; The sidewall of piston hole is provided with seal groove and a guiding groove of annular, is provided with seal ring in seal groove; Described guiding groove is arranged on piston hole aperture place, is embedded with lining in guiding groove.
In above-mentioned Yawing brake of aerogenerator, the sidewall of piston hole is provided with three annular seal grooves, is provided with dust ring, is provided with seal ring in all the other two seal grooves in the seal groove of lining.
Compared with prior art, the beneficial effects of the utility model are:
1. the sidewall at piston hole aperture of the present utility model place is provided with a guiding groove; lining is embedded with in guiding groove; lining is that composite multi-layer material contains adjustment layer, sliding layer, Steel Support and protective layer; opening shape can contain certain distortion; such enhancing piston offset load resistance, protection seal ring is not laterally extruded repeatedly by piston, improves the greasy property of piston side; reduce the friction factor between piston and the inwall of piston hole, extend working life of the present utility model.
2. the sidewall of the utility model piston hole is provided with three annular seal grooves, is provided with dust ring, can prevents dust from entering in piston hole, make the utility model anti-outside contamination ability strong in the seal groove of lining; Be provided with seal ring, two seals circle in all the other two seal grooves, improve dwell pressure of the present utility model and sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view in Fig. 1.
Fig. 3 is B-B sectional view in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Figure 1-3, the utility model comprises break body 1, and break body 1 is provided with a piston hole 7, is provided with piston 2 in piston hole 7, and the bottom of piston hole 7 is provided with oilhole 8 and oilhole 9.The sidewall of piston hole 7 is provided with three annular seal groove 4,5,6 and guiding grooves; described guiding groove is arranged on piston hole aperture place; lining 3 is embedded with in guiding groove; lining 3 contains adjustment layer, sliding layer, Steel Support and protective layer for composite multi-layer material; opening shape can contain certain distortion; strengthen piston 2 offset load resistance; protection seal ring is not laterally extruded repeatedly by piston 2; improve piston 2 side greasy property; reduce the friction factor between piston 2 and the inwall of piston hole 7, extend working life of the present utility model.In three seal grooves, in the seal groove 4 of lining 3, be provided with dust ring, in all the other two seal grooves 5,6, be provided with seal ring.Dust ring in seal groove 4, can prevent dust from entering in piston hole 7, makes the utility model anti-outside contamination ability strong; Seal ring in seal groove 5,6, two seals circle improves dwell pressure of the present utility model and sealing effect.
Working principle of the present utility model is as follows:
When wind-driven generator needs driftage braking, high pressure liquid force feed is by oilhole 8(of the present utility model or oilhole 9) enter the bottom of piston hole 7, high pressure liquid force feed promotes piston 2, piston 2 is pressed onto friction plate on the brake disc of wind-driven generator again, piston 2 and brake disc produce frictional force, brake wind-driven generator.Piston 2 is when braking, be subject to the friction offset loading force of brake disc, piston 2 has movement tendency, owing to being embedded with lining 3 in guiding groove, make piston 2 not directly and the sidewall contact of piston hole 7, prevent seal ring on piston hole 7 sidewall in seal groove (5,6) by the extrusion-deformation of piston 2 transverse force.Lining 3 has lower friction factor, and and piston 2 between there is oil film, piston 2 can be protected not by the inwall scratch of piston hole 7, and then improve the sealing reliability between piston 2 and piston hole 7, extend working life of the present utility model.
