Exciter coupling bolts and solutions for vibration-induced bolt loosening
Julie Pereyra introduced owner/operators to Nord-Lock’s wedge-locking washers that prevent bolts from loosening because of vibration (Fig 5). They are said to reduce maintenance costs and increase worker safety. Steve Busalacchi followed with presentation on the company’s EzFit expansion bolts, which promote safe and easy making and breaking of turbine couplings as summarized in the STUG2020 report elsewhere in this issue.
