Gerotor volume, RPM and displacement calculations
Gerotor volume, RPM and displacement calculations
(OP)
Hello all,
I am working with a gerotor that I have no information about. I have the gerotor sample with me. Can someone please explain to me how I can measure the volume of the fluid the gerotor dispenses? Plus how can I measure the RPM and Torque of the gerotor?
Thanks,
Mo

If I have the physical part (inner and outer gears. I was hoping to use the part to measure the volume.
Ted, the link you sent is not working.

Google for this document.
I'm having difficulty uploading a file.

I have used "standard elements" in a customized design by specifying the custom length of the elements.

If the inner and outer rotors of your gerotor fit neatly (ie minimum volume = approx zero), you can approximate the displacement by filling the pumping space with a measured volume of liquid. During operation, half of this volume is expanding and the other half is reducing. The half that is reducing will be all discharged in a half revolution of the inner rotor so the measured volume is roughly the displacement of the gerotor per rev.
If the minimum volume is greater than zero, the displacement will be reduced by this amount. You may be able to roughly measure the minimum volume by sealing the rotors with a film of grease and filling the minimum volume with a measured volume of liquid. Multiply this by the number of teeth on the inner rotor and subtract from the total volume measured previously.

msakaria, try this. Archimedes to the rescue.
