Heavy-duty shaft coupling strategies
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 […]
Locking assemblies: beyond the basics
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 […]
Intelligent wear protection from Voith
Resolving issues with smarter design The Voith FlexPad Roll End Hub (REH) design greatly increases hub body operational life through a significant reduction in wear. In steel mills work rolls are changed regularly. This requires some clearance between roll end hubs (REH) and work roll ends. The clearance leads to wear and continuously growing play, […]
