    • In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a coupling for causing concurrent rotation and for enhancing the nutational stability of the scroll element. In the preferred embodiment, the nutation reducing means is comprised of an Oldham-type coupling engaging extension members on one of the scroll end plates and drive keys on the other respective end plate. The angular disposition thereof is optimized to cause the Oldham coupling to generate during rotation a moderating moment load in opposition to the tipping moment load of at least one of the scroll elements and thereby enhance the nutational stability of the scroll elements. The moderating moment load of the coupling imposed on the scroll elements may be altered by varying the angular and radial disposition of the center of gravity of the coupling.
    • 在具有两个交错涡旋涡卷的共同旋转涡旋装置中,该涡旋涡卷被固定到围绕平行的非同心轴旋转以产生相对轨道运动的端板,用于引起同时旋转并用于增强涡卷元件的螺旋稳定性的联轴器。 在优选实施例中,止动减速装置包括在其中一个涡旋端板上的十字形联接接合延伸构件和另一个相应端板上的驱动键。 其角度配置被优化以使得奥尔德姆联轴器在旋转期间产生与至少一个涡旋元件的倾翻力矩载荷相对应的调节力矩载荷,从而增强涡卷元件的操纵稳定性。 可以通过改变联轴器的重心的角度和径向布置来改变施加在涡旋元件上的耦合的调节力矩负载。
