Abstract

本发明涉及一种具有行星架(12)、大体中心的太阳轮(11)、外齿圈(13)和通过挠性销组件(15)安装在行星架(12)上的中间螺旋行星齿轮(14)的行星齿轮组。该行星齿轮组还包括位于螺旋行星齿轮(14)的每一个轴端处的滚圈(22)形式的反作用构件，以在行星齿轮(14)上提供相应的径向向内的反作用负载，从而反作用构件(22)一同抵抗行星齿轮(14)上的由于该齿轮上的轮齿负载而产生的扭矩。

Description

行星齿轮组
技术领域
本发明涉及一种具有行星架、大体位于中心的太阳轮、外齿圈和通过挠性销或销组件安装在行星架上的多个中间螺旋行星齿轮的行星齿轮组。
背景技术
在如上所述的布置方式下，可能需要在挠性销上使用螺旋齿轮。然而，这样的布置方式是有问题的，因为在某种意义上这会产生相应的螺旋推压载荷，该载荷将使挠性销围绕其重心扭转，从而导致载荷在齿接触面上分布不当，这可能造成断齿。
发明内容
一方面，该发明包含了一种具有行星架、可安装在轴上的大体中心的太阳轮、外齿圈和可通过挠性销组件安装在轴上的中间螺旋行星齿轮的齿轮，该发明的特征在于该齿轮还包含位于螺旋行星齿轮的每端处的滚圈形式的反作用构件，每个反作用构件在挠性销组件上提供相应的径向向内的反作用负载，以一同抵抗行星齿轮上的由于螺旋齿轮上的轮齿负载而产生的扭矩。
销优选以悬臂方式位于行星架上，反作用负载绕销的悬臂部分的重心作用在相反方向上。
螺旋齿轮可以通过合适的轴承安装在销上，每个反作用负载将通过螺旋行星轮本体产生作用来平衡螺旋推压力矩。滚圈的直径优选比螺旋齿轮的节距圆稍大，从而使其滑动速度最小。
虽然本发明已经按照所理解地进行了限定，但是其还包含之前和下边将要描述的特征的任何创造性组合。
具体实施方式
本发明可以用多种方式来执行，现在通过参考附图描述一个具体的实施例，该附图是通过行星齿轮一部分的竖直剖视图。
总体标为10的齿轮包含中心安装在轴11a上的太阳轮11、行星架12、外齿圈13、安装在行星架12上的中间螺旋齿轮14、以及挠性销组件15。挠性销组件15包含挠性销16和轴承组件19，所述挠性销16以本领域技术人员熟知的方式包括中心销17和外轴套18。
施加在驱动轴11a上的扭矩将会在螺旋齿轮14中如箭头A和B所示的方向上产生螺旋载荷。这些相反的载荷绕销组件16的悬臂部分的重心20产生扭矩，所述扭矩可以使销组件16产生偏转，从而导致在齿面宽度方向上载荷的分布不当。
申请人已经意识到可以通过在螺旋齿轮14的相反两端插入滚圈21和22来避免此种分布不当。这些滚圈21和22产生径向向内的相反的反作用载荷，如螺旋齿轮14相应端处的箭头C和D所示，将认识到这些反作用载荷将抵消由箭头A和B所产生的扭矩。因此滚圈的存在平衡了销组件16上的螺旋倾翻力矩。
