Two-roller machine, in particular roller press having two rotatably mounted, contra-rotating rollers

摘要

In order to provide a two-roller machine, in particular a roller press, whose rotational drive is of simple construction, does not make the machine broad, does not obstruct the deflection motion of the deflection roller (movable roller) and permits an exact counter-synchronous roller rotation without the operation of the roller machine having to be interrupted, it is proposed according to the invention that a slip-on gear mechanism (14, 15) is slipped onto the drive journal of each roller (11, 12) as a reduction gear mechanism, that the input stage of one of the two slip-on gear mechanisms (15) is driven directly by the drive motor (13) and that, for the purpose of counter-synchronous rotational drive of the adjacent slip-on gear mechanism (14), both gear input stages are coupled by means of a cardan shaft (19) which lies at right angles to the rollers (18).
