Selection of main bearings for reciprocating piston compressors
Thread Content
Let’s discuss whether there are piston engines that use rolling bearings for the main bearings; the gas flow rate is 2000 Nm3/H, with a four-row, three-stage design, and an inlet pressure of 0.018 Mpa 40℃； Output: 1.1 Mpa, speed: 590 rpm. It’s not commonly seen; I’m not sure if rolling bearings can be used in piston engines.
I’ve heard others talk about it, but I’ve never seen it myself
Both rolling bearings and sliding bearings can be used in piston compressors. There’s no problem with this
What form should it take then? How is it installed on the crankshaft?
You can take a look at the introduction to the frame mechanism on page P264 of the piston compressor design manual
