Mechnical couple two motors to one pc equipment
(OP)
We have an application that has been descussed electrically, but I would like some input and possible locations where similar installations are in use.
We are planning to increase the HP of a boiler ID fan from 800 to 1600 HP by adding an additional 800 on the opposite end of the fan shaft. The shaft is already extended and keyed for alternate drive. We have questioned the fan manufacture and obtained max speed and hp that the shaft and rotor can take. We have also ruled out going to one 1600 HP motor for various reasons. This will be a direct coupled application and the fans will be run on VFD.
I have concern for shaft growth from heat(425 F) and moving the second motor off of elec center as well as the proper coupling and bearings.
Anyone have experience, good or bad and recommendations as to ways this can work reliably.

This type of coupling allowing for idividual rotor growth is common for turbine/pump. i've also seen with motor/generator through fluid coupling. A coupling with spool piece would also help with elevation thermal growth. that is a small alignment offset when cold, and then going fair when operating.

Consult the representative in your area for "SSS Clutch" by way of Google search. The homepage seems to be unavailable at this time. Their products have been used in marine drive and stationary systems. We had considered the use of the SSS clutch for a fan with turbine and motor drivers.
