Shaft coupling with two connecting flanges and interposed multi-plate assembly - has specially dimensioned screw bolt shaft cylinder sections associated with centring bushes for play-free support.

摘要

The length (L) of the cylinder sections (22) equals the length (L1) of the centring bushes (19) plus a proportion of the thickness (D) of a connecting flange matching the torque to be transferred. The cylinder sections (22) have a surface strength over their entire length (L) which is less than the material strength of the centring bushes and connecting flanges (6,12). The inner radius (R) of the centring bushes provided with inner scraper edges (28) at their insert ends for the screw bolts (14) is greater than the radius (R1) of the bores (27) in the flanges holding the cylinder sections (22) but less than the radius (R2) of the cylinder sections before the screw bolts (14) are fitted. USE/ADVANTAGE - Shaft coupling with increase in the amount of torque which can be transferred.
