Picture or sketch would be helpful.

I want to clear that the reciprocating compressor should have the flywheel for smooth torque. My doubt is how the weight of that flywheel is taken care by crankshaft .

Overhung weights and belt tension can easily be accommodated (at the design stage) by proper bearing selection, stress analysis of components, etc.  If the machine is used as designed, then you should have minimal issues.  Is this a machine that has been modified in the field, beyond what the OEM intended?

Most reciprocating compressors use the drive sheave as a flywheel.

The pictorial shows what Danny is referring to.  Note the OD of the flywheel has belt grooves.

Note as well that one bearing is larger than the NDE bearing.  This is done to accommodate the overhung load as well as belt tension.

If you are converting/modifying an existing machine, get the OEM involved.  I know of a few instances where people converted a machine and in a relatively short period of time ended up with a flywheel rolling across the floor because the shaft broke at the extension..
