Description

兆瓦级十分流风力发电增速箱
[技术领域]
本发明涉及风电增速技术领域，一种兆瓦级十分流风力发电增速箱。
[背景技术]
风能是一种取之不尽、用之不竭、无污染的可再生能源。预测至2020年，风电将成为我国第三大能源，因此风电增速箱蕴藏着几百亿的巨大市场。风电增速箱是风力发电机组三大核心技术之一，目前世界主流机型为1.5～2MW。由于风电增速箱是在环境恶劣、偏远地区六七十米高空，因此对增速箱提出苛刻的要求：使用寿命20年，轴承寿命130000小时，尽可能小尽可能轻、装拆维修方便。我国几家大型企业相继取得下述六项专利权：(一)南高齿“风力发电机增速齿轮箱(0620068477)(系0420080174的改进)；(二)重齿“行星平行轴传动风力发电齿轮箱”(02222633)；“行星传动风力发电增速箱”(03237681)；(三)东方汽轮机厂“风力发电装置的齿轮箱”(200610021443)。其中：重齿“行星传动风力发电增速箱”实质上是三级定轴增速传动(重庆大学教授、博士后曾在学报上发表过研究论文)，其余均为行星加两级平行轴结构。显然，上述发明创新的承载能力主要取决于输入级行星传动。行星传动之所以承载能力高于硬齿面的关键在于三分支分流(因为只有三个行星轮)。上述发明有一共同点，均采用将内齿圈作为联接件之一的联接箱体，目的是减轻单件重量。联接件的最大缺点是机械强度差，增加了加工误差和安装误差，此外各联接件之间温度差异，受力不同所产生的变形亦不尽相同。由于无法如国外大公司采用斜内齿+渗碳体火+磨齿工艺，使我们的产品与之有较大差距。
[发明内容]
本发明目的在于提供一种体积、重量均小于国外产品、毋须采用斜内齿磨齿工艺、拆装方便的兆瓦级十分流风电增速箱。为实现上述目的必须解决的技术问题是如何使功率获的十分流，因为分流越多承载力越大，体积越小、重量越轻。
技术方案：本发明提出了一种以定轴传动理论为基础、动轴行星结构为框架的定轴式多分流增速箱，包括机座、输入轴、内齿圈、机架、双联齿轮及中心轴齿套，其特征在于：(1)与机座联结的机架上均布五只双联齿轮，机架主体置于内齿圈内腔；(2)双联齿轮由轴齿轮联接传动齿轮而成，其中：内齿圈与轴齿轮之间有二只相同的介轮，形成二分流；而传动齿轮与中心轴齿套之间为五分流，于是从内齿圈至中心轴齿套形成十支分流，最后由第三级输出齿轮轴增速输出。
本发明有益效果：(1)重量比现有产品轻35～45％，外形缩小40～50％；(2)单件轻，装、拆维修方便；(3)国产插齿机、磨齿机可以加工5MW机型的齿轮，而大大降低制造成本。
[附说说明]

A.机架(5)为一环形薄壁短圆筒状、带加强筋的铸件，机架法兰与机座输出端联接，而机架主体置于内齿围(6)内腔；
B.双联齿轮为五只均布，其中：(α)五只轴齿轮(8)中的每一只与内齿圈之间有二只完全相同的介轮(14)，构成从内齿圈至轴齿轮的二分流，介轮由轴承支承在心轴(15)上，心轴固定在机架上；(b)五只传动齿轮(7)与中心轴齿套(12)相啮合，形成五分流，使增速系统形成功率十分流结构；
C.中心轴齿套(12)的轴颈上联接输出大齿轮(13)轴齿套的两端由轴承分别承在机架(5)与端盖(11)的中心孔中，与大齿轮啮合的输出轴齿轮(10)由轴承分别支承在支架(9)与端盖相应孔中，支架联接在端盖内端面上。
D.机座(1)为薄壁短圆筒状、带加强筋的整体铸件，装上端盖(11)后，外观为一封闭的短圆筒，从一端输入轴(2)输入，另一端非同轴的齿轮轴(10)输出；
E.输入轴(2)由轴承(3)、(4)分别支撑支承在机座(1)与机架(5)的中心孔中。
工作原理：当风叶通过胀套联接器驱动输入轴(1)后，与之联接的内齿圈(6)经二只介轮(14)同向转动轴齿轮(8)及与之联接的传动齿轮(7)，五只均布的传动齿轮带动中心轴齿套(12)，最终由大齿轮(13)，带动轴齿轮(10)高速输出驱动发电机。工作中，齿轮及轴承的润滑采用溅油与强制油循环润滑。
