Expansion sleeve coupling installation and removal method

1. Installation: The expansion sleeve has been coated with lubricant at the factory and can be installed and used directly. When installing, screw three bolts in the screw holes of the other flanges first and then evenly distribute them along the circumference to open the inner sleeve and outer sleeve. Then put the expansion sleeve into the hub hole in the design position. Use the force plate to tighten the bolt. The tightening method is to tighten each bolt to only 1/4 of the rated torque at a time. The tightening sequence is defined by the open seam. The left and right cross symmetry are tightened in order to ensure that the rated torque value is achieved.
2. Disassembly: First, loosen all bolts a few times before disassembling. Then screw the expansion sleeve into the bolt hole in the disassembled screw hole.
First, the expansion sleeve before installation
1 Dimensions, tolerances and surface roughness of the joints should meet the requirements
2 Apply a thin layer of lubricating oil (without molybdenum disulfide additive) to the joint surface of the expansion sleeve after cleaning. The bonding surface must be clean, free of dirt, non-corrosive and non-damaging.
Second, the expansion sleeve installation
1 Push the connected parts onto the shaft so that the designated position is achieved.
2 Insert the expansion sleeve that loosens the screw into the coupling hole of the drive roller shaft and the casting wheel hub. To prevent the coupling from tilting, tighten the screw.
