    Appropriate tolerance for shaft and housing for bearings?

    Hello, So I am designing a shaft which would involve bearings on the shaft, and a housing which would enclose the shaft. The shaft would be slightly bigger than the bearing hole which would create an interference fit so the bearings would stay on the shaft tightly. At the same time the bearing...

    How to calculate natural frequency of timing belt

    Hello I am designing a shaft and it will be powered via belt pulley system. The ideal RPM of the shaft is 8000 RPM. How do I calculate the natural frequency of the timing belt to ensure resonance is never met? From what I read online it has to do with belt pretension, but even then I am little...

    How to calculate vibrations on a rotating shaft?

    I haven’t taken a vibrations class sadly. So the shaft is for a spindle designed for milling which is rotating at 8000 RPM. There is a force on one end of the spindle which makes contact with the material. What I have done so far in simulation software is calculate the resonance frequencies with...

    How to calculate vibrations on a rotating shaft?

    Is there a way to calculate the vibrations on a shaft rotating at a certain rpm? Is there a way to accurately simulate this?

    How to add area moments of inertia for varying cross sections

    So the shaft design would be for a CNC machine primarily used for milling. The area moment of inertia would be put into an equation I found from papers. Area moment of inertia is used for deflection calculation which is what I am focusing on. Yeah what's confusing me is the different diameters...

    How to add area moments of inertia for varying cross sections

    Hello I am doing a shaft design layout for a spindle to minimize deflection and I have to calculate the area moment of inertia for a shaft overhang.The shaft overhang is the distance from a bearing to the end of the shaft. Here is a picture detailing the location of the overhang. The black...
