Coupling for friction engagement rotational connection of machine parts has sliding sleeve with coating with increased adhesive friction between inner generated surface of sleeve and outer generated surface of second machine part

摘要

The coupling (10) for the friction engagement rotational connection of metal machine parts has a circular cylindrical sliding sleeve (13) installed between the circular cylindrical outer generated surface (11) of the second machine part (12) and the circular cylindrical inner generated surface (16) of the first machine part (23). The sliding sleeve has a coating (27) which between the inner generated surface (14) of the sleeve and outer generated surface of the second part has a greater adhesive friction than between the outer generated surface (15) of the sleeve and inner generated surface of the first machine part.
