    • In the embodiment of the invention described in the specification, a drive assembly for an eccentrically driven mass has a drive shaft which drives the mass by a first eccentric device and a secondary shaft, driven synchronously with the drive shaft, which drives a second eccentric device spaced from the first eccentric device so as to guide the mass in a constrained manner. The connection between the second eccentric device and the mass includes a resilient mounting. In order to avoid, or at least reduce, sinusoidally varying stresses imposed on the resilient mounting during operation as a result of deflection of the drive shaft, the eccentricity of the second eccentric device is larger than the eccentricity of the first eccentric device by at least a portion of the magnitude of the maximum deflection of the drive shaft in the region of the mass occurring during operation.
    • 在本说明书中描述的本发明的实施例中,用于偏心驱动的质量块的驱动组件具有驱动轴,该驱动轴通过与驱动轴同步地驱动的第一偏心装置和次轴驱动质量,驱动轴驱动第二偏心装置 与第一偏心装置间隔开,以便以受约束的方式引导质量。 第二偏心装置与质量块之间的连接包括弹性安装。 为了避免或至少减少由于驱动轴的偏转而在操作期间施加在弹性安装件上的应力的正弦变化的应力,第二偏心装置的偏心量至少比第一偏心装置的偏心量至少 驱动轴在操作过程中发生质量区域的最大偏转量的一部分。

    • A displacement machine for compressible media, with at least one displacement chamber arranged in a stationary housing and rendered in the manner of a groove extending with a spiral shape, and with a band-shaped or tongue-shaped displacement body associated with each displacement chamber and likewise rendered in spiral shape is described. The displacement body is held on a discoid rotor, which can be driven eccentrically relative to the housing, in such a manner that during operation, each of its outside wall points performs a circular movement bounded by the peripheral walls of the displacement chamber. The curvature of the displacement body relative to the curvature of the displacement chamber is dimensioned such that the displacement body nearly comes in contact with the radially inner and outer peripheral walls of the displacement chamber. For sealing the radial gap formed between the stationary housing and the rotor a sheet metal strip with a roughness applied in a precisely targeted fashion is held on one of the surfaces of the components to be sealed. In order to create an arrangement which can be produced as simply and easily as possible, the sheet metal strip is to be provided with outwardly projecting scale-like embossings and said sheet metal strip is to be constituted by an aluminum foil cemented on to the component.
    • 一种用于可压缩介质的排量机,具有布置在固定壳体中的至少一个位移室,并以呈螺旋状延伸的凹槽的形式,以及与每个位移室相关联的带状或舌形位移体,以及 同样呈现为螺旋状的描述。 位移体被保持在可相对于壳体偏心驱动的盘状转子上,使得在操作期间,其每个外壁点执行由位移室的周壁界定的圆形运动。 位移体相对于位移室的曲率的曲率的尺寸使得位移体几乎与位移室的径向内周壁和外周壁接触。 为了密封形成在固定壳体和转子之间的径向间隙,具有以精确目标方式施加的粗糙度的金属薄片被保持在待密封部件的一个表面上。 为了产生尽可能简单且容易地制造的布置,金属板条应设置有向外突出的鳞片状压花,并且所述金属板条由将铝箔胶合到构件上 。
