摘要： A tensioning system including a base and an arm pivotally coupled to the base, the arm having an engagement surface and being configured to pivot relative to the base about a pivot axis. The system further includes a biasing mechanism operatively coupled to the arm to bias the arm relative to the base, and a seal assembly sealingly positioned between the arm and the base. The seal assembly is coaxial with the pivot axis and configured to accommodate relative axial movement between the base and the arm and relative radial movement between the base and the arm while still maintaining a seal therebetween.

摘要： Low-noise pulleys and methods of constructing low-noise pulleys are disclosed. In a first aspect, first and second pluralities of arms extending radially outward from the outer hub to the outer rim are angularly offset from each other about the axis of rotation to eliminate symmetry across the lateral midline of the pulley. In a second aspect, the radially outermost ends of a plurality of arms are arcuately spaced apart according to a pitch sequence describing a pseudo-random pattern of relative spacings so as to reduce or eliminate rotational symmetry of the pulley. In a third aspect, features of the first and second aspects are combined, and in one embodiment, first and second pluralities of arms are, respectively, approximately oppositely canted so as to vary the arcuate spacings of the laterally outermost ends of the arms.
摘要翻译：公开了低噪声滑轮和构造低噪声滑轮的方法。在第一方面，从外轮毂径向向外延伸到外轮缘的第一和第二多个臂围绕旋转轴线彼此成角度地偏移，以消除皮带轮横向中线上的对称性。在第二方面，多个臂的径向最外端根据描述相对间隔的伪随机图案的俯仰序列而弧形间隔开，以便减小或消除滑轮的旋转对称性。在第三方面中，组合了第一和第二方面的特征，并且在一个实施例中，第一和第二多个臂分别大致相反地倾斜，以便改变臂的横向最外端的弓形间距。
