Description
Technical field
The utility model relates to a kind of change oar break of wind power pitch motor.
Background technique
In variable propeller pitch control, becoming oar break is a kind of very important safety component.It operates mainly in power failure state, when pitch motor change oar terminates or wind power generating set shuts down power-off, becomes oar break and protects into pitch-controlled system provides safe and reliable dead electricity to brake; Meanwhile, when needs regulate blade, the braking state of pitch motor can after brake guaranties, be removed.The change oar break of current use, if its brake coil breaks down, by locking, because now blade is in non-full feathering state, therefore, will may there is blade and be scraped very large risk such as disconnected grade by typhoon in motor shaft.Especially for 6MW superhigh power wind power generating set, this unit requires to realize mutiredundant design in variable blade control system, controls the reliable feathering of pitch motor, once become oar brake malfunctions, brings very large loss can to this unit.Take two breaks superposed for this reason, it exists, and size is large, complex structure, cost increase, inconvenient defect is installed.
Model utility content
The technical problems to be solved in the utility model is to overcome the complex structure that prior art exists, the defect that cost is high, size is large, installation is inconvenient, providing a kind of change oar break of wind power pitch motor.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of change oar break of wind power pitch motor, it comprises the flange that an electromagnet system and is fixed on described electromagnet system, described electromagnet system and described flange are all sheathed on a motor shaft, a rotor-support-foundation system is provided with between described electromagnet system and described flange, its feature is, described electromagnet system comprises an electromagnet, an armature, an elastic member, described electromagnet is wound with one first coil and one second coil, described electromagnet is provided with a blind hole, and the two ends of described elastic member are connected to the bottom of described blind hole and described armature respectively; Described rotor-support-foundation system comprises an axle sleeve and a brake disc, described axle sleeve is sheathed on described motor shaft by a fixed component, described brake disc is sheathed on described axle sleeve and between described armature and described flange, is provided with and carries out the gap of movement for the axis of motor shaft described in described drag friction rim between described armature and described flange.
Preferably, described elastic member is spring.Spring has good elasticity, can provide effective elastic force for braking.
Preferably, described fixed component comprises a connecting key and a back-up ring, and described connecting key is located between described motor shaft and described axle sleeve, and described shield ring sleeve is located at described motor shaft and is arranged between described motor shaft and described axle sleeve.Being fixedly connected with between axle sleeve with motor shaft is effectively realized by connecting key and back-up ring.
Preferably, described flange by a screw and described electromagnet affixed.Like this, easy to connect, link cost is low.
Positive progressive effect of the present utility model is: use this break, even if there is a coil to break down, break still can be made to open to another coil electricity, and then control the reliable feathering of pitch motor, therefore, this break has the advantage of double safe, double insurance.In addition, this break also has that braking torque is large, the simple advantage of structure.Meanwhile, this break can reduce the working life of the temperature rise of coil, energy saving, prolongation break effectively.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figure 1, a kind of change oar break of wind power pitch motor, it flange 7 comprising electromagnet system and be fixed on electromagnet system, electromagnet system and flange 7 are all sheathed on motor shaft 8, are provided with rotor-support-foundation system between electromagnet system and flange 7.Electromagnet system comprises electromagnet 1, armature 3, spring 10, and electromagnet 1 is wound with the first coil 2 and the second coil 11, and electromagnet 1 is provided with blind hole, and the two ends of spring 10 are connected to bottom and the armature 3 of blind hole respectively; Rotor-support-foundation system comprises axle sleeve 5 and brake disc 4, axle sleeve 5 is sheathed on motor shaft 8 by fixed component, brake disc 4 is sheathed on axle sleeve 5 and between armature 3 and flange 7, is provided with the gap of carrying out movement for brake disc 4 along the axis of motor shaft 8 between armature 3 and flange 7.Fixed component between axle sleeve 5 and motor shaft 8 comprises connecting key 6 and back-up ring 9, and connecting key 6 is located between motor shaft 8 and axle sleeve 5, and back-up ring 9 is sheathed on motor shaft 8 and is arranged between motor shaft 8 and axle sleeve 5.Flange 7 is affixed by screw 12 and electromagnet 1.
The braking force of this break is from spring 10, and the electromagnetic force that electromagnet 1 produces is used for brake off.When motor shaft 8 is in running order, electromagnet 1 produces electromagnetic force, holds armature 3, and spring 10 is in compressive state, and armature 3 is separated with brake disc 4.When wind power pitch motor regulates blade to specified position, first coil 2 and the second coil 11 power-off, electromagnet 1 no longer produces electromagnetic force, spring 10 relies on the elastic force of self that armature 3 and brake disc 4 are pressed to flange 7, make to produce frictional damping moment of torsion between the brake disc 4 of rotation and flange 7, thus motor shaft 8 is stopped operating, now break is in braking state.
When wind power pitch motor starts to regulate blade, first coil 2 and the second coil 11 are energized or single energising simultaneously, electromagnet 1 all can produce a powerful electromagnetic field, armature 3 Compress Spring 10 attracted on electromagnet 1 under the effect of electromagnetic force, armature 3 is separated with brake disc 4, motor shaft 8 can with brake disc 4 normal rotation, and now break is in releasing state.
Use this break, even if there is a coil to break down, break still can be made to open to another coil electricity, and then control the reliable feathering of pitch motor, therefore, this break has the advantage of double safe, double insurance.Meanwhile, this break can reduce the working life of the temperature rise of coil, energy saving, prolongation break effectively.This break also has that braking torque is large, the simple advantage of structure.
This break optimizes the Redundant Control scheme of variable propeller pitch control greatly, system architecture can be made relatively simply to ensure again cheap, can be widely used in wind-power generating system.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
