Title:
A DRIVE MECHANISM OF A FOUR-WHEEL FRICTION SCREW PRESS
Document Type and Number:
WIPO Patent Application WO/2008/098446
Kind Code:
A1
Abstract:
A drive mechanism of a four-wheel friction screw press includes a rotating horizontally flywheel (1) which connects with a screw (16). An upper friction wheel (2) and a lower friction wheel (3) are mounted symmetrically on two sides of the flywheel (1) and are driven by a motor (14). Four friction wheels rotate in a same direction. The shafts of the upper friction wheel (2) and the lower friction wheel (3) connect movably with two opposite ends of a level (11) by pins (13). Through swaying around a pivot, the level driven by an oil hydraulic cylinder (9) controls the upper friction wheels (2) and the lower friction wheels (3) alternately to press and to leave the edges of the flywheel (1). In working time, friction wheels at two sides press closely the flywheel with similar force, which eliminates the lateral force added on the screw.
