Connecting assembly between pipe end and shaft end uses off-set rows of uniformly spread out protrusions on overlapping zone of shaft end to provide play-free connection

摘要

The pipe end (6) engages over the shaft end (7) by a certain amount and in the overlapping zone the shaft end is provided with several adjoining but off-set rows of protrusions spread evenly round the circumference. The protrusions have rounded contours in cross-section. The off-set stagger between two rows of protrusions seen in the circumferential direction is less than the largest diameter of one protrusion.
