摘要

The connection (10) is assembled of a bolt (12) with a cylindrical central segment (18) and two conical outer segments (20) and two spreading sleeves (22) with conical inner surfaces joined to both ends. The sleeves (22) are axially moved onto the bolt (12) with a suitable tool and held at a machine part (16) after spreading. Each of the sleeves (22) is provided with an inner thread (24) at its outer section (26) as well as the bolt (12) at the inner surface of a central bore. The sleeve (22) can be easily removed using a puller (28) of a matching size inserted into the treaded areas (24, 32).
