Vibrator for vibrating stations comprises unbalanced masses of one unbalanced body connected to each other via a braking device defining a torque

摘要

Vibrator (1) comprises at least one unbalanced body having two unbalanced masses (2, 3) engaging in each other and set in rotation by a motor drive. The unbalanced masses are rotated relative to each other for infinitely variable adjustment of the unbalanced body. The unbalanced masses of one unbalanced body are connected to each other via a braking device (11) defining a torque. Preferred Features: The unbalanced masses are connected to each other via a friction clutch as the braking device, a multiple clutch, or a form-locking ratchet clutch.
