    • A bearing assembly for use on a printing press is disclosed. A printing press includes a support frame. A shaft having a first end and a second end fixedly attached to the support frame, the shaft arranged to define a longitudinal axis relative to the support frame. A cylinder, the cylinder having a cylinder bore formed therethrough; and a bearing assembly having an outer circumferemce and an inner bore, the outer circumference sized insertion within the cylinder bore and the inner bore sized to rotatably engage the shaft. The bearing assembling includes an adjustment assembly including a first tapered portion and a second tapered portion, the first and second tapered portions cooperate to permit angular adjustment of the cylinder relative to the longitudinal axis of the shaft, the angular adjustment of the cylinder being about an axis perpendicular to the support shaft longitudinal axis.

    • In order to facilitate removal and replacement of blanket and impression sleeves in a rotary offset printing press, the blanket and plate cylinders are supported in cantilever fashion. The cantilevered cylinders allow axial removal and replacement of the blanket and impression sleeves without temporary support of the cylinder and without removal of any bearings. Each cylinder is rotatably supported on a cantilevered support shaft having a bore therethrough. A drive shaft operatively connected to a drive motor extends through the support shaft bore and engages the inner surface of the generally hollow cylinder. A blanket or impression sleeve mounted on the cylinder is removable using compressed air, which is routed through a bore in the drive shaft and through a plurality of radially oriented passage in a flange on the end of the drive shaft. Each radial passage communicates air to an exit port on the surface of the cylinder, which introduces enough air between the cylinder and the sleeve to permit the sleeve to slide freely for axial removal and replacement.
    • 为了便于在旋转胶版印刷机中移除和更换橡皮布和印模套筒,橡皮布和印版滚筒以悬臂方式支撑。 悬臂式气缸可以轴向拆卸和更换橡皮布和压印套筒,无需临时支撑气缸,也不会拆卸任何轴承。 每个气缸可旋转地支撑在具有穿过其中的孔的悬臂支撑轴上。 可操作地连接到驱动马达的驱动轴延伸穿过支撑轴孔并与大致中空圆柱体的内表面接合。 安装在气缸上的毯子或印模套筒可使用压缩空气来移除,压缩空气通过驱动轴中的孔并穿过驱动轴端部的法兰中的多个径向取向的通道。 每个径向通道将空气连通到气缸表面上的出口,其在气缸和套筒之间引入足够的空气,以允许套筒自由滑动以进行轴向移除和更换。
