电机、风力发电机组及刚度调节装置Motor, wind turbine and stiffness adjustment device

技术领域technical field

本发明涉及风电技术领域,特别是涉及电机、风力发电机组及刚度调节装置。The invention relates to the technical field of wind power, in particular to a motor, a wind power generating set and a stiffness adjusting device.

背景技术Background technique

风力发电机是将风能转换为电能并输出的电力设备。如图1所示,风力发电机包括定子(图中未标示)、定轴1、转子20、转轴9。风力发电机的定轴1与外部的底座5连接,底座5可以对风力发电机提供稳定的支撑作用。风力发电机的定子包括定子支架10和铁芯绕组6。定子支架10包括:支架本体2和设置在支架本体2上的支撑件3。铁芯绕组6设置在支架本体2上。定轴1穿过支撑件3,且与支撑件3固定连接。定轴1的第一端与底座5连接,具体的,定轴1的第一端具有法兰11,底座5的一端具有法兰51,定轴1通过法兰11与底座5的法兰51连接。定轴1的第二端与转轴9通过轴承转动连接。转轴9与转子20连接。定轴1的轴线与定子中心线重合。A wind turbine is an electrical device that converts wind energy into electrical energy and outputs it. As shown in FIG. 1 , the wind generator includes a stator (not shown in the figure), a fixed shaft 1 , a rotor 20 and a rotating shaft 9 . The fixed shaft 1 of the wind generator is connected with the external base 5, and the base 5 can provide stable support for the wind generator. The stator of the wind power generator includes a stator support 10 and an iron core winding 6 . The stator bracket 10 includes: a bracket body 2 and a support member 3 arranged on the bracket body 2 . The iron core winding 6 is arranged on the bracket body 2 . The fixed shaft 1 passes through the support member 3 and is fixedly connected with the support member 3 . The first end of the fixed shaft 1 is connected to the base 5. Specifically, the first end of the fixed shaft 1 has a flange 11, and one end of the base 5 has a flange 51. The fixed shaft 1 connects to the flange 51 of the base 5 through the flange 11. connect. The second end of the fixed shaft 1 is rotationally connected with the rotating shaft 9 through a bearing. The shaft 9 is connected to the rotor 20 . The axis of the fixed shaft 1 coincides with the centerline of the stator.

其中,风力发电机在风力发电时的工作过程为:在风力的推动下,叶轮带动转子20转动,转子20相对定子转动,使发电机产生电能。发电机转子20在相对发电机定子转动时,发电机转子20会对发电机定子产生激励,激励频率会随着发电机转子20的转速变化在一范围值内变化。当风力发电系统中发电机定子受到的激励的频率变化至与其固有频率相接近时,发电机定子的振幅会显著增大,出现共振现象,强烈的共振会降低风力发电机组的运行性能,甚至会对风力发电机组的结构造成破坏。Wherein, the working process of the wind generator when wind power generation is: driven by the wind, the impeller drives the rotor 20 to rotate, and the rotor 20 rotates relative to the stator, so that the generator generates electric energy. When the generator rotor 20 rotates relative to the generator stator, the generator rotor 20 will excite the generator stator, and the excitation frequency will vary within a range of values as the rotational speed of the generator rotor 20 changes. When the excitation frequency of the generator stator in the wind power generation system changes to be close to its natural frequency, the vibration amplitude of the generator stator will increase significantly, and resonance will appear. Strong resonance will reduce the operating performance of the wind turbine, and even Damage to the structure of the wind turbine.

为了降低共振现象的发生,现有的做法是:通过控制风力发电机叶轮转速从而调节激励频率的数值,在变化的激励数值靠近发电机固有频率时,可调节叶轮转速,使激励频率快速通过固有频率。或是通过对风力发电机内部机构进行加强处理,提高其刚度,将风力发电机固有频率提高至激励频率变化范围值以上,从而避免共振现象发生。In order to reduce the occurrence of resonance phenomenon, the existing method is to adjust the value of the excitation frequency by controlling the impeller speed of the wind turbine. When the changing excitation value is close to the natural frequency of the generator, the impeller speed can be adjusted so that the excitation frequency quickly passes the natural frequency. Or by strengthening the internal mechanism of the wind turbine to increase its stiffness, the natural frequency of the wind turbine is raised above the value of the excitation frequency variation range, thereby avoiding the occurrence of resonance.

在实现本发明过程中,发明人发现现有技术中至少存在如下问题:通过调节风力发电机转速的做法会降低发电量;通过对风力发电机内部进行加强处理的做法会很大程度上增加风力发电机重量,无法满足风力发电机机头重量载荷的重量要求。In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the power generation will be reduced by adjusting the speed of the wind generator; the wind power will be greatly increased by strengthening the inside of the wind generator The weight of the generator cannot meet the weight requirements of the wind turbine head weight load.

Wherein, the details may be set according to the actual needs of the user.

在具体实施本发明实施例时,上述的刚度调节装置4的第一端和第二端所在的直线可以平行于定子中心线,以使刚度调节装置4分别对预定固定部件以及支撑件3施加可调节的力的方向平行于定子中心线,从而对电机的轴向刚度进行调节。采用平行于定子中心线的方案,可以确保可调节的力能更有效的对刚度进行调节。当然,在一个替代的实施例中,刚度调节装置4对预定固定部件以及定子的支撑件3施加力的方向也可以与定子中心线的方向不平行,只要保持大致平行即可,同样可以达到对电机的轴向刚度进行调节的目的。When implementing the embodiment of the present invention, the straight line where the first end and the second end of the above-mentioned stiffness adjusting device 4 are located may be parallel to the center line of the stator, so that the stiffness adjusting device 4 can respectively apply a certain force to the predetermined fixing part and the support member 3. The direction of the adjusted force is parallel to the center line of the stator, thereby adjusting the axial stiffness of the motor. Adopting a scheme parallel to the center line of the stator can ensure that the adjustable force can adjust the stiffness more effectively. Of course, in an alternative embodiment, the direction in which the rigidity adjusting device 4 exerts force on the predetermined fixed component and the support member 3 of the stator may not be parallel to the direction of the center line of the stator, as long as it is kept approximately parallel, the same can be achieved for The purpose of adjusting the axial stiffness of the motor.

在具体实施本发明实施例时,前述的刚度调节装置4的数量可以为多个,该多个刚度调节装置4绕定子中心线呈圆形均匀分布。在本发明实施例中,由于刚度调节装置4的数量为多个,从而使刚度调节装置4对预定固定部件以及支撑件3施加的力具有更宽的调节范围,进而使本发明电机的轴向固有频率能够在更大的范围内进行调节。又因为刚度调节装置4绕定子中心线呈圆形均匀分布,使支撑件3以及预定固定部件上的受力更加均匀,可以有效防止支撑件3以及预定固定部件局部受力过大而造成应力集中的现象。When implementing the embodiment of the present invention, the number of the aforementioned stiffness adjustment devices 4 may be multiple, and the plurality of stiffness adjustment devices 4 are uniformly distributed in a circle around the center line of the stator. In the embodiment of the present invention, since there are multiple stiffness adjustment devices 4, the force exerted by the stiffness adjustment device 4 on the predetermined fixing member and the support member 3 has a wider adjustment range, thereby making the axial direction of the motor of the present invention The natural frequency can be tuned over a wider range. And because the stiffness adjusting device 4 is evenly distributed in a circle around the center line of the stator, the force on the support member 3 and the predetermined fixed part is more uniform, which can effectively prevent the support part 3 and the predetermined fixed part from being overstressed locally and cause stress concentration The phenomenon.

当然,在一个替代的实施例中,前述的多个刚度调节装置4也可以不绕定子中心线呈圆形均匀分布,具体来说,该多个刚度调节装置4也可以不均匀布置,其具体的分布方式可以根据用户的实际需求以及电机结构自身特点来进行设置。Of course, in an alternative embodiment, the aforesaid plurality of stiffness adjustment devices 4 may not be evenly distributed in a circular shape around the centerline of the stator, specifically, the plurality of stiffness adjustment devices 4 may also be arranged unevenly, specifically The distribution method can be set according to the actual needs of users and the characteristics of the motor structure itself.

在具体实施本发明实施例时,上述的预定固定部件可以为定轴1或底座5等。该预定固定部件是当电机在工作时相对于电机上的运动部件而言的。当电机在工作时,定轴1、底座5以及定子等为预定固定部件,转子和转轴9等为运动部件。When implementing the embodiment of the present invention, the aforementioned predetermined fixing component may be the fixed shaft 1 or the base 5 and the like. The predetermined fixed part is relative to the moving part on the motor when the motor is working. When the motor is working, the fixed shaft 1, the base 5 and the stator are predetermined fixed parts, and the rotor and the rotating shaft 9 are moving parts.

On the contrary, when the first adjusting nut 412 is reversely screwed, the force received on the flange 51 of the support member 3 and the base 5 is reduced, thereby reducing the axial stiffness of the motor of the present invention, and further reducing the strength of the motor of the present invention.

如图6和图7所示,本发明实施例三的第一示例以预定固定部件为底座5为例进行具体结构的阐述。具体的,在该实施例三的第一示例中,前述的刚度调节装置4的第二端与底座5的法兰51或法兰51的延伸部连接。刚度调节装置4包括花篮螺栓部件431、第二螺柱432和第三螺柱433。第二螺柱432具有相对的第一端4321和第二端4322。第三螺柱433具有相对的第一端4331和第二端4332。花篮螺栓部件431置于底座5的法兰51与支撑件3之间。花篮螺栓部件431具有贯穿两端的通孔(图中未标示),通孔的第一端(图中未标示)设有左旋内螺纹,通孔的第二端(图中未标示)设有右旋内螺纹。第二螺柱432具有与左旋内螺纹相适配的外螺纹。第二螺柱432的第一端4321与支撑件3连接,第二螺柱432的第一端4321作为刚度调节装置4的第一端。第二螺柱432的第二端4322与通孔的第一端螺纹连接。第三螺柱433具有与右旋内螺纹相适配的外螺纹,第三螺柱433的第一端4331与底座5的法兰51连接,第三螺柱433的第一端4331作为刚度调节装置4的第二端。第三螺柱433的第二端4332与通孔的第二端螺纹连接。由于通孔两端的螺纹旋向相反,当向一个方向转动花篮螺栓部件431时,花篮螺栓部件431可以通过第二螺柱432和第三螺柱433同时拉紧支撑件3和底座5的法兰51,以增大支撑件3和底座5上所受到的力,从而使本发明电机的轴向刚度增大,进而提高了本发明电机的轴向固有频率;反之,当向相反的方向转动花篮螺栓部件431时,花篮螺栓部件431通过第二螺柱432和第三螺柱433同时放松支撑件3和底座5的法兰51,以减小支撑件3和底座5上所受到的力,从而使本发明电机的轴向刚度减小,进而降低了本发明电机的轴向固有频率。然而,当反向拧动花篮螺栓部件431到一定程度时,第二螺柱432和第三螺柱433又会对支撑件3和底座5产生推力而增加定子的轴向刚度。其中,本实施例三中的刚度调节装置4对支撑件3和底座5提供拉力或推力,应用该刚度调节装置4的电机的轴向刚度的增量随拉力或推力的增大而增大。在本实施例中,通过转动花篮螺栓部件431即可对本发明电机的轴向固有频率进行调节,调节较方便。As shown in FIG. 6 and FIG. 7 , the first example of the third embodiment of the present invention takes the base 5 as an example to illustrate the specific structure. Specifically, in the first example of the third embodiment, the second end of the aforementioned stiffness adjusting device 4 is connected to the flange 51 of the base 5 or the extension of the flange 51 .
