摘要： In a pulley assembly, an annular joint member made of a high polymer material is disposed between an outer ring of a bearing and a light metal pulley. The joint member has a coefficient of thermal expansion larger than that of the pulley. The outer ring has a coefficient of thermal expansion smaller than that of the pulley. The pulley has an annular boss, an annular rim, and a plurality of spokes which have side faces each consisting of a surface parallel to an axial direction of the pulley. Front faces of the spokes are positioned on one identical imaginary surface of revolution, and rear faces of the spokes are also positioned on one identical imaginary surface of revolution.

摘要： There is provided a bearing sealing device capable of substantially completely preventing a leak of grease. A taper end portion of an axial extension of the bearing sealing device has an opposite surface and a rake face that forms a specified rake angle with the opposite surface. The opposite surface forms a narrow passage between the opposite surface and an outer peripheral surface of an inner ring. The narrow passage allows air to pass easily, but it allows grease to hardly pass therethrough. Further, the axial extension includes part of a core metal that extends axially and has its foremost end located axially inside an axial outermost end of the outer peripheral surface of the inner ring. Grease moving axially outwardly on the outer peripheral surface is moved along the rake face of the taper end portion and then guided along a cover portion of the bearing sealing device to an outer ring. The part of the core metal prevents the axial extension from being bent radially outwardly by a centrifugal force.
摘要翻译：提供了能够基本上完全防止润滑脂泄漏的轴承密封装置。轴承密封装置的轴向延伸部的锥形端部具有相对的表面和与相对表面形成指定前角的前刀面。相对的表面在相对表面和内环的外周表面之间形成窄通道。狭窄的通道允许空气容易通过，但它允许油脂几乎不通过。此外，轴向延伸部包括轴向延伸的一部分芯体，其最前端位于内圈的外周面的轴向最外端的轴向内侧。在外周面上沿轴向向外移动的润滑脂沿着锥形端部的前刀面移动，然后沿着轴承密封装置的盖部被引导到外圈。芯金属的一部分防止轴向延伸通过离心力径向向外弯曲。
