Means for assembling reciprocator crosshead bearings
Thread Content
Let’s discuss the methods used by various people to assemble the crosshead copper sleeves and rod end bearings of their reciprocating compressors. Not long ago, I saw in a manufacturing plant’s assembly workshop that the components were installed after being cooled using a refrigerant medium – this is what’s known as the temperature difference assembly method. However, at customer sites, the number of installations per year is usually low, and such conditions are not available. Forcing the components into place under pressure can lead to significant deformation of the sleeves or bearings. Are there any other good methods?
Our small end tiles are installed on a press
Generally, a press is used to apply pressure, followed by grinding the inner ring of the copper sleeve.
Installed on an upper press – high success rate
Additional note: Be careful with the upper assembly of the press. As for the success rate on the fifth floor, it mainly depends on the quality of the assembly. There have been instances where turning resulted in waste, and there have also been cases of compression deformation. Therefore, the quality of assembly depends on many factors; turning it to the appropriate size on a lathe after assembly is also necessary, and problems can arise if the positioning is not accurate.
