Hi all,
I have a peristaltic pump that i need to rotate at 26 rev/min. The gear arrangement attached to the pump is calculated at 13.1:1 therefore I am assuming an input speed of 340rev/min is required to produce a reduction in speed to the desired output of 26 rev/min.
Gear A (1st driver) - 12 teeth
Gear B (1st driven) - 43 teeth
Gear C (2nd driver) - 9 teeth
Gear D (2nd driven) - 33 teeth
My problem is that I need to know what Force is required to turn my pump and thus the the force required by my drive unit, a 'power spring' to transmit the desired force. I do not have any measuring devices other that a spring scale graduated in Kg. I did however determine the force required to rortate the input shaft, albeit not at the correct speed which came out at an average of 1.8 Kg over 10 tests. I did this by tying a thread around the input shaft to the gear arrangement and then attaching the other end to the spring scale and simply pulling and recording the max pull in Kg over 10 separate attempts.
Can I determine the torque (power) i need from my power spring to turn my pump at a constant speed of 26 rev/min?
Thanks in advance
