Give Your Gears a Break - Select the Right Coupling! - May/June 1987
The article "Give Your Gears a Break - Select the Right Coupling!" appeared in the May/June 1987 issue of Gear Technology.
How important is the right choice of coupling in determining successful machine design? Consider the following example. A transmission of appropriate size was needed to transfer the speed of the engine driver to that of the driven generator. The transmission was properly selected and sized to endure the rated power requirements indefinitely, but after only a short time in operation, it failed anyway. What happened? The culprit in the case was a coupling. It provided the necessary power and protection against misalignment but it lacked the ability to isolate the gears from the torque peaks of the diesel engine.
