WOBBLE SCREENING MACHINE WITH ROTARY-ACTUATOR ADJUSTMENT OF THE SLANT OF THE SKEW TAPPET

摘要

The wobble screening machine has a shaft (10) driven in rotation. Eccentrically mounted on the shaft (10) is a counter-slanted skew tappet (12) which is stayed in a plate (18) that can be cross-adjusted to change the degree of eccentricity (22) to the shaft (10). The skew tappet (12) supports an elastically held screening structure (14) which is set in oscillation by the revolving skew tappet (12). For adjusting its slant the skew tappet (12) is mounted on a rotary table (52), which has a wedge surface slanted counter to the axis (44) of the skew tappet (12) and can be rotationally adjusted and set as this wedge surface rests against a wedge surface of the plate (18) slanted counter to the shaft axis (20). The slants of the wedge surfaces are counterbalanced in at least one relative angle position of rotary table (52) and plate (18).
