A drive shaft from the source of power take-off can alternatively be used to drive the compressor. It is
extremely important that the angularity of the drive shaft, including the universal joints, be within the limits
specified by the manufacturer. The power take-off shaft and the compressor rotor drive shaft must always
be parallel. This gives the same angle at each universal joint and prevents excessive wear. The forks of
the universal joint on the drive end must be installed parallel to the forks on the driven and universal.
There are many types of universal joints that can be used. However, a constant velocity universal joint as
previously described will reduce the possibility of torsional vibration. If a slip joint or spline is used on the
drive system, it should be placed between the two universal joints for best results.
Regulation
The standard regulation system supplied with CMH Series Compressors is designed to provide capacity
control for the compressor only. Variable speed control of a driver engine is possible with additional
equipment. Consult Ingersoll-Rand Company, Specialty Products Department for technical assistance for
these applications.
The adjustment and operation of the standard regulation system is described in Section 6, Operating
Instructions.
