Gear couplings are three-piece flexible shaft couplings that are used to connect driving and driven shafts in mechanical power transmission assemblies. Flexible shaft couplings are used to counter the inevitable misalignment that occurs between connected shafts.
How do you choose a gear coupling?
Design considerations: (1)Torque rating. One of the key factors in selecting a coupling is its torque rating — the amount of torque that it can transmit. (2)Service factor (3)Outside diameter (4)Weight (5)Moment of inertia (6)Torsional deflection (7)Torsional stiffness (8)Backlash
