Spindle for a spinning or twisting machine, with a plastics centering tube, has a metal reinforcement ring at the zones subject to radial forces to prevent a stress overload on the tube

摘要

The spindle (1), for a spinning or twisting machine, has a plastics centering tube (12) with a metal reinforcement ring (18-20) in the zones (13,21,23) where radial forces occur. The reinforcement ring can be at the tube clamping point at the housing, at the footstep bearing bush (10), and at the damping coil (15).
