Couplings play a critical role in energy equipment — especially wind turbines. These durable components, which connect the gearbox to the generator, ensure the rotor blade system is operating as it should. Without the right coupling, a wind turbine can’t function properly, driving up maintenance costs and downtime. These scenarios are not welcome—especially since any […][Read More]
Move beyond traditional coupling designs to improve performance and cut costs Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be over-engineered with regard to stiffness. In many ways, this design approach makes perfect sense. Keyed connections have […][Read More]
Although numerous methods exist for coupling two components, choosing the best option for the intended application requires an understanding of all available technologies. For example, when clamping a hub onto a shaft or axle, splined or keyway-based couplings are a popular choice. Another traditional method of connecting gears to shafts involves shrink fitting, which uses temperature differences […][Read More]
