兆瓦级封闭行星差动风电增速箱
技术领域  本发明涉及风电增速箱技术领域，一种兆瓦级封闭行星差动风电增速箱。 
背景技术  背景技术“兆瓦级行星差动风电增速箱”(200910152360.2)的有益效果是拆、装方便、可在高空大修；比国内外先进机型轻40-55％。但也存在下述严重问题： 
(A)理论计算(下表星轮数1∶2)发现：①两内齿圈圆周力Ft不相等，因而会使输入轴圆筒扭曲变形，因此准内齿圈加宽b2＝180、245、263及276；②当齿宽＝b1+b2＝288、380、408及431，显然，如果再加上内撑盘D宽度的话，输入轴圆筒内花键很长而增大机加工难度，精度亦难保证，同时齿过宽会降低齿向、齿间负荷的均匀，因此说内撑盘D是不合理构思； 
Figure BSA00000388409300011
(B)当输入轴圆筒很长时，还会出现一个问题：拉出差动与准行星封闭组件后，输入轴圆筒因自重而“低头”，封闭组件便很难装回去了，因此说内撑盘D是不合理构思； 
(C)由于准行星轮(np＝8～12)尺寸小只能用滑动轴承、因而必须采用润滑泵经分配器对滑动轴承强制润滑，其可靠性大大优于自润滑，过滤润滑油是轴承长寿命重要因素； 
(D)从上表可看出，星轮数比为1∶2.3～2.5时，二内齿圈圆周力Ft及齿宽b相近。 
发明内容  本发明目的在于提供一种“兆瓦级行星差动风电增速箱”(200910152360.2)改进后的新构思“兆瓦级封闭行星差动风电增速箱”。 
技术方案改进技术方案： 
(1)输入轴圆盘联接薄壁短圆筒，圆筒内花键与装在圆筒内的内齿圈外花键滑动配合； 
(2)准行星轮用滑动轴承支承在准星轮轴上，准星轮轴为盲空轴，轴上有5-10个小油孔，大端盖内有润滑油分配器F，分配器小油管装在准星轮轴进口处，强制润滑可靠性优于自润滑； 
(3)机座端面处有一圆孔K，短圆筒上有一螺孔，用来吊住输入轴圆筒，不使圆筒“低头”； 
(4)差动行星轮与准行星轮数量1∶2.3～2.5，使两组轮齿的圆周力相近。 
有益效果比照背景技术其创造性在于： 
(一)输入轴圆盘联接的薄壁短圆筒内花键机加工艺好、成本低； 
(二)封闭组件拆、装方便； 
(三)二内齿圈圆周力相近使输入轴圆筒不扭曲变形。
