Research on Machining of for Pulp Making Shoe Pressure Matching Rollers
The pulp making shoe pressure matching roller is a key component of papermaking equipment,mainly composed of the shoe pressure matching roller shaft head(drive side),the shoe pressure matching roller shaft head(operation side),and the shoe pressure matching roller shell.The two end shaft heads and the middle roller shell adopt interference fit,and after assembly,they are fastened and reinforced by screws.Due to the large size and heavy weight of the product,with interference assembly,it is extremely difficult to control the heating method and time required to ensure the assembly clearance.The lifting of the workpiece and the positioning of the matching hole are also difficult during assembly.At the same time,high tolerance requirements for the shape and position of the two end shaft heads and roller shells make the machining and manufacturing more difficult.This article introduces the machining method of the pulp shoe pressure matching rollers.
