Locating ring location
Locating ring location
(OP)
For a belt driven centrifugal fan, with the shaft supported by a pair of spherical-roller bearings with their respective SAF-type housing, where should the locating ring be installed to fix one of the bearings, in the impeller side bearing housing or the pulley side housing? Thanks.





RE: Locating ring location
On a hot fan I'd lock the fan bearing to avoid stuffing the fan into the shroud. Then Axial shaft growth would tend to mis-align the belts, which I don't consider a real big deal.
What I do worry about is asking a heavily loaded bearing to slide in a housing. If the fan/blower wheel is real fat, and the belt pull is not close to vertical, then the opposite bearing wants to fly upward. In that case I would probably lock the fan bearing, because it won't want to slide very much.
