Abstract

本发明公开了一种风电用组合式行星架。它是将具有连接板的行星内架与具有孔板的行星外架套接,行星内架的每个连接板只能在中间位置安装传递扭矩的连接件、并具有轴向尺寸能与连接件尺寸紧密配合的环形接合面,内、外行星架用连接件连接、用紧固件紧固,装配后行星外架与行星内架只在环形结合面接触,其它部位悬空。由于扭矩作用在行星架连接板的中间位置,所以不论行星架孔板和连接板是否变形或变形大小,都不会使行星轴线与中心轮轴线产生偏斜,都将始终保持平行。保证了行星轮与内齿轮在齿长方向上的偏载最低,可以有效地降低太阳轮与行星轮偏载,保证两盘行星轴承的受力大小、方向基本相同,大大提高了行星轴承的使用寿命,确保了行星齿轮传动的可靠性。本发明特别适合变扭矩输入的场合使用。

Description

风电用组合式行星架
技术领域
本发明涉及一种发电增速用的行星齿轮箱行星架的创新,具体地是一种组合式行星架,特别适合于风力发电机浆叶与发电机之间的行星齿轮增速使用。
背景技术
在一般行星齿轮箱中行星齿轮的轴心线与中心轮的轴心线产生的偏斜角度的大小与齿轮箱的传动功率或扭矩成正比,在变功率或变扭矩传递动力时,造成齿轮偏载和两盘行星轴承偏载,严重影响计算的轴承寿命的可靠性。尤其是兆瓦级风电行星齿轮箱属典型低速重载变扭矩动力传动,在工程应用中一般采用齿轮修形来解决此类问题,但由于齿轮修形是按某一恒定扭矩(工作点)设计的,在不同的风电场中,这个恒定的扭矩是不同的,这就造成了齿轮偏载和两盘行星轴承的偏载,从而导致行星轴承的提前失效。
发明内容
本发明的目的就是为了克服现有技术中的上述缺陷,设计出一种结构合理、能有效克服上述弊端的风电用组合式行星架。
本发明的目的是这样实现:即具有连接板的行星内架与具有孔板的行星外架套接,行星内架的每个连接板只能在中间位置上装有传递扭矩的连接件、并具有轴向尺寸能与连接件尺寸紧密配合的环形接合面,内、外行星架用连接件联接、用螺栓紧固,装配后行星外架与行星内架只在环形结合面接触,其它部位悬空。
所述行星架上至少装有三个行星轮,行星架上的连接板和连接件与行星轮数量相同,在行星轴上装有两盘或多盘轴承,在轴承的外圈上装有行星齿轮。
所述行星外架上的孔板对称布置。
所述行星内架上的扭矩输入端可具有加强边。
本发明具有如下优点:这种组合式行星架结构,由于扭矩作用在行星架连接板的中间部位,所以不论行星架侧板和连接板是否变形或变形大小,都不会使行星轴线与中心轮(亦称太阳轮或内齿轮)轴线产生偏斜,都将始终保持平行。保证了行星轮与内齿轮在齿长方向上的偏载最低,再对太阳轮进行扭转齿向修形,可以有效地降低太阳轮与行星轮偏载,保证两盘行星轴承受力的大小、方向基本相同,大大提高了行星轴承的使用寿命,确保了行星齿轮传动的可靠性,从而达到本实用新型的目的。

具体实施方式
参照图1、图2,本发明主要由四个组件组成,即具有连接板的行星内架(5)与具有孔板的行星外架(3)套接,在行星内架(5)上的连接板[(5)-①]的中间位置安装传递扭矩的连接件(7)[如圆柱销或其它形状的连接件]、并具有轴向尺寸尽量小的、能与连接件(7)尺寸紧密配合的环形接合面[3-②],内、外行星架(5、3)用连接件(7)连接、用紧固件(6)固定[如用紧固螺栓或其它紧固件],装配后行星外架(3)与行星内架(5)只在环形结合面[3-②]接触,其它部位悬空。在行星外架(3)的孔板[3-①]设有固定行星轴(4)的孔,行星架上至少装有三个行星轮,行星架上的连接板[5-①]和连接件(7)与行星轮(1)数量相同,在其行星轴(4)上装有两盘或多盘轴承(2),在轴承的外圈上装有行星齿轮。行星外架(3)上的孔板[3-①]对称布置。图示仅是组合行星架的一种形式,行星轮和组合式行星架上的连接板的数量、根据传递扭矩的大小,可以为四个、五个、六个并对称布置。行星内架上的扭矩输入端可具有加强边。
在风电行星增速箱上,扭矩从行星内架(5)左端输入,通过连接件(7)将扭矩传给行星外架(3),再通过行星外架(3)上对称布置的孔板将扭矩传给行星轴(4),行星轴(4)上装有两盘或多盘轴承(2),在轴承(2)的外圈上装有行星齿轮。这种组合式结构,不论输入的扭矩大小,行星内架(5)连接板产生多大的扭转变形,装在行星外架(3)上行星轴的轴心线,都将始终与中心轮轴线保持平行。从而大大减小了齿轮副的偏载,和行星轮中轴承载荷的分配不均,提高了轴承和齿轮的可靠性。故本结构特别适合用于变扭矩输入的场合,如风力发电,水力发电等。
