PRESS CRANK MECHANISM Russian patent published in 2012 - IPC B30B1/26 F16H21/18 

FIELD: machine building.

SUBSTANCE: crank mechanism of press includes eccentric shaft related to the drive and on which the piston rod is installed. Piston rod is connected by means of a spherical hinge to the support in the slide, which is made in the form of a bearing plate with a cover plate. Slide is installed in the base with possibility of translational movement. Support is installed in the slide by means of guide fences and has the possibility of relative translational movement in the direction perpendicular to the plane of crank mechanism.

EFFECT: possible distortions in kinematic pairs of the mechanism are compensated and possible adjustment of gaps in slide-to-piston connection is provided, which allows improving the reliability of the mechanism.
