摘要： A rotary pump has a housing 1 with a driven rotor 7 installed in the housing 1. Vanes 12 are connected around the periphery of the rotor 7. Helical springs 14 are supported against rotor 7, which, acting on an inner surface of vanes 12, press the free end of the vanes 12 against the bore 6 of the housing 1. Each spring 14 has two coaxial sections of turns which spiral in opposite directions so that the springs 14 press the vanes 12 against the bore 6 of the housing 1 without tilting. These sections of turns are each designed with an adjacent support end 21 on the outer or inner section and a bail section, which is arranged between the inner and outer end of the sections of turns, connecting the inner and outer ends of these sections of turns rigidly together, and which projects radially beyond the sections of turns. The two support ends 21 or the bail section of the helical spring 14 are on a support surface 24 of the rotor 7, and the bail section or the support ends 21 pointing toward the free end of the vane 12 are arranged elastically to press against the inner surface of the vane 12.
摘要翻译：旋转泵具有壳体1，其具有安装在壳体1中的从动转子7.叶片12围绕转子7的周边连接。螺旋弹簧14被支撑在转子7上，转子7作用在叶片12的内表面上，将叶片12的自由端压靠在壳体1的孔6上。每个弹簧14具有两个相反方向螺旋的同轴旋转部分，使得弹簧14将叶片12压靠在壳体1的孔6上而不会倾斜。这些匝部分设计成具有在外部或内部部分上的相邻的支撑端21和设置在匝部的内端和外端之间的吊环部分，连接这些匝部的内端和外端刚性在一起，并且其径向突出超过匝部。螺旋弹簧14的两个支撑端21或吊环部分在转子7的支撑表面24上，并且引导部分或指向叶片12的自由端的支撑端21被弹性地布置以压靠叶片12的内表面。

摘要： In a shaft end bearing, the shaft end has a convex curved friction or sliding surface of revolution, and cooperates with a correspondingly curved concave friction or sliding surface. At least one of these surfaces has grooves inclined to the circumferential direction for effecting the dynamic build-up of fluid lubricant. The grooves are separated into two different annular zones spaced apart by a zone having no grooves and serving as a throttle.
摘要翻译：在轴端轴承中，轴端具有凸曲面的摩擦或旋转的滑动表面，并与相应弯曲的凹形摩擦或滑动表面配合。这些表面中的至少一个具有朝向圆周方向倾斜的槽，以实现流体润滑剂的动态积聚。凹槽被分隔成两个不同的环形区域，该环形区域被没有凹槽的区域间隔开并用作节流阀。
