Coupling retrofits and upgrades Here are the considerations for applying nonlubricated, high-performance types

摘要

Turbomachinery upgrading to increase plant production or equip-fel ment reliability is quite common. With lubricated gear couplings often limiting the run length of process machines, nonlubricated, high-performance couplings are frequently considered for these equipment upgrades.However, dry couplings, i.e., couplings that do not require lubrication, are typically taking the place formerly occupied by gear couplings in more than just the figurative sense. Indeed, a common approach is to closely duplicate the geometry of the gear coupling so that the.
