Abstract

The adjuster is for eccentric shafts for the drive of eccentric presses. The connecting rods are moved by eccentrics. Each body is formed by a shaft eccentric and a surrounding eccentric sleeve. These are continuously turnable relative to each other, and can be fixed in any position by a friction-torque-coupling. The eccentric sleeve (10) has a sleeve-shaped extension (18), non-turnably connected to it, and positioned concentrically to its bore (11). This section alone forms the releasable friction torque-coupling (20) between eccentric sleeve and shaft eccentric.
