摘要： A pulley device for supporting a belt of chain tensioning idler or a runner roller includes a bearing having an outer ring mounted for rotation relative to a coaxial inner ring and at least one pulley part that is C-shaped in cross section. The pulley part has an inner portion with a frustoconical inner surface mounted on an outer cylindrical surface of the outer ring, an outer cylindrical portion having an outer cylindrical surface configured to support a belt or a chain, and an intermediate portion extending radially inward from the cylindrical outer portion to the inner portion. The pulley part is integral and has an open end on an axial side opposite the intermediate portion. The frustoconical surface extends inwardly towards the outer ring, and the inner surface is force fitted onto the outer cylindrical surface of the outer ring.

摘要： A pulley device provides a pulley and a bearing. The pulley has at least one C-shaped pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one material deformation forming an axial stop for the pulley.

摘要： A sprocket of the type typically used for driving a plastic conveyor belt is split through the drive shaft hole at its center, so that the sprocket can be assembled over a drive shaft without disrupting the conveyor assembly. Two sections which form the drive shaft preferably are identical, and may be machined from high molecular weight polyethylene. In a preferred embodiment the two sections are assembled together by interlocking features shaped as jigsaw puzzle pieces. The two sections are placed against the drive shaft and are moved together in the axial direction of the drive shaft, thus sliding the sections together. One or more fasteners may be provided at easily accessed locations to permit the two sections from sliding apart.

摘要： A split sprocket assembly. The sprocket assembly does not require additional separate fasteners and extends substantially parallel to the axis of the drive shaft. Further, the sprocket assembly includes first and second sprocket sections having integrally formed connecting device to connect the sprocket members about the shaft. The connecting device preferably includes a projection formed on one sprocket section and a complementary recess formed on the other sprocket section. The geometry of the projection and the recess is preferably that of a dove-tail shape. The connecting device further includes a device for preventing axial movement of the sprocket sections relative to one another. In one embodiment, the sprocket assembly does not require any additional separate fasteners at all, and the preventing device includes locking members to provide a cylindrical snap fit. In an alternative embodiment, the preventing device includes fasteners extending in a direction perpendicular to a plane including the axis of the shaft and through both sprocket members.
摘要翻译： 分体链轮组件。 链轮组件不需要额外的单独的紧固件并且基本上平行于驱动轴的轴线延伸。 此外，链轮组件包括具有整体形成的连接装置的第一和第二链轮部分，以将链轮部件围绕轴连接。 连接装置优选地包括形成在一个链轮部分上的突起和形成在另一个链轮部分上的互补凹部。 突起和凹部的几何形状优选为鸽尾形状。 连接装置还包括用于防止链轮部分相对于彼此的轴向移动的装置。 在一个实施例中，链轮组件根本不需要任何附加的单独的紧固件，并且防止装置包括锁定构件以提供圆柱形卡扣配合。 在替代实施例中，防止装置包括在垂直于包括轴的轴线并且通过两个链轮构件的平面的方向上延伸的紧固件。

摘要： A split hub assembly including a split sprocket, a split hub, and members to connect the split sprocket together. The formed split sprocket is disposed over the split hub by complementarily tapered surfaces to maintain the split hub coupled together. Installation and removal of the present invention is significantly easier than standard prior art devices, plus it provides interchangeability of hubs and sprockets.

摘要： An improved mechanical donut and donut assembly in which donuts made of plastic materials are formed in segments that facilitate installation, removal and/or replacement for manufacture and maintenance. The donuts of the preferred embodiments are made of urethanes, especially polyurethane, while fastening members such as threaded bolts are made of nylon. The relative characteristics of the urethanes and nylon are such as to facilitate a self-tapping feature for the nylon bolt.
