Description

一种固定端球笼式等速万向节
技术领域
本发明涉及等速万向节的领域，具体涉及一种固定端球笼式等速万向节。
背景技术
现有固定端球笼式等速万向节，其主要具备以下构建：钟形壳1，其在内球面形成有沿轴向延伸的多个球道，且具有在轴向上分开的开口侧6和里侧5；星形套2，其在外球面形成有与钟形壳1的球道成对的多个球道；多个钢球4，它们夹设于钟形壳1的球道与星形套2的球道之间并传递转矩；保持架3，其对钢球4进行保持，且具有与钟形壳1的内球面和星形套2的外球面配合的外球面和内球面。钟形壳1的内球面、星形套2的外球面、保持架3的外球面和内球面的中心都重合于万向节球笼中心O点。钟形壳1的球道中心O2和星形套2的球道中心O1相对万向节中心反向偏置，偏置距大小相等。在工作角为0°的状态下，由于偏置距的存在，在钟形壳1与星形套2对置的球道之间形成楔角，且均朝向钟形壳1开口侧开放，大小为α。
现有技术钟形壳1的球道和星形套2的球道作用于钢球4的轴向力，推动保持架3外球面和钟形壳1内球面、星形套2外球面和保持架3内球面接触。这样导致运转过程中这些部位的球面之间摩擦磨损严重，不利于固定端球笼式万向节的低发热和高效率。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种固定端球笼式等速万向节。
本发明的目的是通过如下技术方案来完成的：这种固定端球笼式等速万向节，主要包括钟形壳、星形套、保持架、钢球、里侧、开口侧、A球道、B球道，钟形壳内球面形成有沿轴向延伸的多个球道，且具有在轴向上分开的开口侧和里侧，星形套外球面形成有与钟形壳的球道成对的多个球道，钟形壳的球道与星形套的球道之间夹设多个钢球并传递转矩，钢球通过保持架进行保持，保持架具有与钟形壳的内球面和星形套的外球面配合的外球面和内球面，钟形壳、星形套的球道分为A球道和B球道两种。
所述A球道为非交叉型，在A球道处钟形壳和星形套的球道为一段单一圆弧，球道中心与万向节中心O重合，钟形壳的球道和星形套的球道中心同心，形成的楔角为0°。
所述B球道为交叉型，在B球道处钟形壳球道的球道中心线的平面相对于万向节的轴线N-N倾斜，并且在周向上两个相邻倾斜球道的倾斜方向为相反方向，星形套的球道和钟形壳的球道成对的相对B-B平面成镜像对称，倾斜角度为θ。
所述钢球数量优选为8。
本发明的有益效果为：本发明在钟形壳和星形套上周向配置成对的反向交叉球道，通过交叉球道相反方向倾斜，对钢球产生的轴向力方向也相反，可以抵消作用于保持架的轴向力，从而减小保持架与钟形壳和星形套球面的摩擦磨损，减小了发热量，提高了传递效率；同时非交叉球道与交叉球道相邻，避免了球道倾斜导致相邻球道之间距离一端大一端小的问题，增大了相邻球道间的小端距离，提高了强度。

实施例2：在实施例1的基础上，沿交叉球道中心线的纵向剖面上钟形壳1的球道为两条圆弧连接或者不限于两条。第二球道圆弧R2具有与第一球道圆弧R1不同的形状，第一球道圆弧R1和第二球道圆弧R2在比万向节中心O靠开口侧6连接，以包含工作角0°的状态下的万向节中心O的平面B作为基准，星形套2的球道与钟形壳1的成对的球道形成为镜像对称。
