Description

一种风电齿轮箱花键润滑冷却方法
技术领域
本发明涉及一种风电齿轮箱花键润滑冷却方法,属于风电齿轮箱技术领域。
背景技术
在风电齿轮箱中,太阳轮左端为齿轮、右端为外花键,花键套内设有内花键,此两件装配到一起,使内、外花键啮合。一般地,当考虑齿轮箱润滑冷却的时候,重点研究齿轮、轴承的润滑,往往忽略了花键的润滑冷却,其实,花键在传递扭矩的时候,极易升高温度,甚至发生胶合现象。
发明内容
本发明的目的是针对上述问题,提供一种简单而有效的风电齿轮箱花键润滑冷却方法,以保证花键运行可靠。
实现本发明目的的技术方案如下:
在风电齿轮箱装配中,太阳轮和太阳轮压板之间形成一圈10mm宽的圆周间隙;在太阳轮和花键套的内、外花键啮合部位右侧的花键套上以太阳轮轴线为对称开有两个与太阳轮轴线成27°的夹角的孔,润滑油从太阳轮和太阳轮压板之间间隙流入,工作状态下,齿轮箱轴线与水平面倾斜5°安装,通过搅油或飞溅过来的润滑油经倾斜5°的圆柱斜面流入到内、外花键啮合部位,对内、外花键润滑;当花键套上的孔随着工件旋转至正下位置时,流入内、外花键部位的油液从孔中流出,实现油液的循环。
所述太阳轮压板右端为弧面过渡。
本发明的优点是:本发明的方法中机械结构简单,加工制造难度低、装配难度低,不会因加工精度差而出现问题;无需增加润滑冷却零件就能达到对花键润滑冷却的目的,以保证花键在传递扭矩的时候,温度正常。
附图说明
图1是本发明的机械原理图。
图中:1、太阳轮,2、太阳轮压板,3、花键套,4、花键套上的孔。
具体实施方式
参照附图,在风电齿轮箱中,太阳轮1上的花键为外花键,花键套上的花键为内花键,太阳轮和花键套装配到一起,使花键啮合,在太阳轮上花键左侧用太阳轮压板2轴向定位,太阳轮压板右端为弧面过渡,太阳轮压板与花键套用螺栓连接到一起。各部件固定好后,太阳轮与太阳轮压板之间形成一圈10mm宽的圆周间隙。在太阳轮和花键套的内、外花键啮合部位右侧的花键套上以太阳轮轴线为对称开有两个与太阳轮轴线成27°的夹角的孔4,润滑油从太阳轮和太阳轮压板之间间隙流入,工作状态下,齿轮箱是倾斜5°安装,通过搅油或飞溅过来的润滑油经倾斜5°的圆柱斜面流入到花键部位,以达到润滑花键的目的。当花键套上的孔随着花键套旋转至下方的过程中,油液会顺着孔流出,实现循环润滑冷却的功能。
