The structure of butt joints of VSI Crusher is various. There are fork lug type joints, frame type joints, chute joints, pulley skateboard joints, hinge joints and so on. The structure of the joint hole is also varied. Some joints are divided into a base body and a bushing. The bushing is installed in the base body; some joints have bearings in the base body, and the bearings are installed in the base body; some joints do not have bushings and bearings, and directly connect the hole shaft. The connection form of the joint and the component structure is also various. Some joints are integrated with the component structure. The joint itself is a part of the component structure: some joints are separated from the component structure, and the joint is connected to the component structure through a connecting piece. Some joints are simple in structure and convenient for docking; some are complex in structure and difficult to dock. Some joints are simple in connection with the structure and have a design compensation function. Appropriate position adjustment is allowed when the components are docked: some joints are complicated in connection with the structure and do not have a design compensation function, which requires high position accuracy of the joint.
In short, the joint structure of the impact crusher has a variety of structural forms, and structural designers often care about the structural requirements and use requirements of the component joints, but do not care or pay enough attention to the finishing requirements of the component joints, making it difficult to finish the components. Or it cannot be finished.
