| 摘要 |
This invention relates to a device for releasably mounting thin walled cylindrical members in a machine involving rotary working operations, such as rotary screens used in rotary printing presses. The device comprises cylindrical end members adapted to be mounted on the rotary machine and adapted to fit within and engage inner peripheral flanges at the ends of the cylinder. The end members comprise an annular slot which contains a ring member expandible by suitable pressure means. Each ring member contains an outer annular groove adapted to engage the inner flange at each end of the cylinder upon expansion of the ring member thereby securing the ends of the cylinder on each end member. The ring member can be a steel band expandable by the action of a pressurized air tube mounted in the annular slot, or alternatively, the ring member can be an outer wedge ring disposed in the annular slot with an inner wedge ring in the slot which can be axially moved and thus radially moving the outer wedge ring. With the cylinder mounted between the end members, it is capable of being stretched in an axial direction. |
