MOVABLE JAW ATTACHMENT ASSEMBLY Russian patent published in 2016 - IPC B02C1/02 

FIELD: machine building.

SUBSTANCE: group of inventions relates to jaw crusher and, in particular, to movable jaw drive. Crusher movable jaw attachment assembly comprises movable jaw pull and/or push force mechanical drive. Drive comprises sleeve (121) with internal chamber, displacement element (123) to return the movable jaw and bearing support frame (122) for connection of at least part of unit with part of crusher. Piston is made with possibility of reciprocating rectilinear sliding movement within chamber. Piston rod (124) is made with possibility of longitudinal reciprocating drawing and retraction relative to sleeve. Rod first end (204) is located farthest from sleeve. Sleeve section (200) is connected to movable jaw. Displacement element is connected to rod section substantially in, or about its first end (206). Support frame comprises mounting section (208) for displacement element attachment in or near its second end (207). Installation section is located between sleeve section and rod first end along lengthwise axis so that displacement element extends over at least a rod section.

EFFECT: higher reliability and compactness of attachment assembly during installation and movable jaw position and displacement control.
