Embodiment Construction
[0034] Such as figure 1 , 2 Shown: a split-type extrusion roller assembly structure and assembly method, the split structure adopts the form of conical surface matching: the matching part of the roller shaft is a conical surface, and the inner hole of the roller sleeve or the matching part of the outer tapered surface of the roller shaft are set to multiple channels Oil groove conical surface. The roller shaft and the roller sleeve are connected by interference fit, and the roller sleeve is assembled by hydraulic pressure. This assembly structure method using high-pressure oil to expand the inner hole of the roller sleeve greatly shortens the assembly cycle of the extrusion roller sleeve, greatly reduces the stress concentration phenomenon caused by the interference connection between the roller shaft and the roll sleeve, and improves the quality of the roll. The service life of the extrusion roller of the press and the grinding product is improved, thereby improving the pr...
