Dear all, I would like to know how to calculate the maximum load that a roller/wheel can stand under set conditions. The roller/wheel works in a sliding...

To measure shaft endplay, mount a dial indicator at the end of a shaft and move the shaft in the axial direction. In most cases, this requires a fixture with a ball bearing on the central shaft that allows pushing and pulling the shaft while it is rotated to seat the bearing rollers....
The cross-sectional cut configuration for an axial electrodynamic bearing is shown below. The conducting disc is attached to the rotor and the magnetic material (iron yoke) is used to guide the magnetic fields of the PMs, such that the magnetic flux lines are parallel to the rotor axis. This...
with L10 hrs N = 16667/N * (C/P)3 = speed (rpm) The Equivalent Radial Load is defined as: P = XFr + YFa with Fr Fa X Y = radial load (lb) = axial load (lb) = see table below = see table below For radial contact ball bearings calculate P with X = 1.0 and Y=1.0. Th...
Ball screws are prone to a certain amount of noise because of ball bearing recirculation. On the other hand, lead screws generally produce very little noise, although stiction, frictional impedance to sliding, sometimes produces chatter or squeal in the absence of lubrication. ...
If you know how much power you are planning to get and you know the wind speed and rough efficiency then you can calculate the required cross-sectional area of your turbine. If you know the cross-sectional area of your turbine then you know the blade radius. If you know the tip speed ...
Wind power increases as a cube function of wind speed. That means, doubling the wind speed provides an 8 fold increase in wind power (23= 2x2x2 = 8). This provides an easy way to calculate the WOPR. Like so: Rwop= (Vcut out/Vrated power)3 ...
some interest in using them in therapy. Targeted radionuclide therapy offers the potential to deliver extremely lethal radiation to cancer cells [31]. This form of treatment can boost the harmful radiobiological effects on cancer cells while decreasing the negative effects of radiation on healthy ...
