What causes a coupler to fail?
What causes a coupler to fail? Couplings fail for several reasons, but the primary causes are improper selection for the particular application; excessive misalignment; improper, inadequate, or insufficient lubrication; harsh environmental or operating conditions; and excessive speeds or loads. What is the leading cause of coupling wear? Common causes of wear or failure include normal wear (again, gear coupling teeth are designed to wear over time), lack of lubrication, torque overload, misalignment, fatigue (of flange or bolt), and thrust loading (sleeve seal end rings). What causes coupling chatter? Lack of lubrication (Gear and Grid couplings) Improper torquing of fasteners. Excessive...
