Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications!
Shrink-fits are assembled by heating them to temperatures where the expansion exceeds the interference. Required heating temperature can be calculated as
dt = δ / α di (1)
where
dt = temperature heating (oC, oF)
δ = diametric interference (mm, in)
α = coefficient of linear expansion (m/moK, in/inoF)
di = initial diameter of hole before expansion (mm, in)
Diametric interference can be calculated as
δ = dt α di (2)
Search is the most efficient way to navigate the Engineering ToolBox.
The Engineering ToolBox provides a wide range of free tools, calculators, and information resources aimed at engineers and designers. It offers detailed technical data and calculations for various fields such as fluid mechanics, material properties, HVAC systems, electrical engineering, and more.
The site includes resources for common engineering tasks, such as calculating physical properties (e.g., density, viscosity, thermal conductivity), converting units, and designing systems like heating and water distribution.
With sections on everything from acoustics to hydraulics, it serves as a comprehensive tool for both students and professionals in technical and engineering disciplines.
