Sectional pipe-rolling roller - with annular eccentric slot on joint of band and bush ends

摘要

The roller comprises a bush with flange and annular band on it with channel on outside. To improve reliability under alternating turning moment, an annular eccentric slot is made on the joint line of the ends of the band and bush, and a ring is pressed into the slot. When alternating turning moment is transmitted from the drive shaft, the annular band tends to shift angularly relative to the bush. The ring acts as a wedge to prevent such a shift occurring.
