This week’s photo highlights a trunnion skewing adjustment in action.
A dial indicator (bottom left of photo) is used to measure the movement of the trunnion wheel bearings. If the bearings are not positioned correctly, they should be adjusted.
The purpose of the trunnion skewing adjustment is to train the rotary drum to go either up or downhill, without the drum riding hard on the thrust rollers; the drum will ideally float between the two thrust rollers, without touching either of them.
Trunnion wheel skewing adjustments should be performed after any rotary drum installation, and they should be included as part of routine or annual inspections. Without properly aligned trunnion wheels, the weight distribution of the drum will be uneven.
Trunnion skewing adjustments are just one component of our commissioning and annual drum inspections. To learn more about FEECO’s Customer Service Engineering services, contact us today!
