I have this setup:
-Pully with a mass attached.
-Worm gear drive to lower the mass with a constant speed. (Section A-A)
Now if we look at the cross-section A-A, we can see the worm gear drive:
M1 is the torque applied by the mass on the pully and hence on the gear.
Now my question is:
If M1 > M2 is it still possible to lower the mass at constant speed ? ...or in other words, is it possible to make the gear (above the worm gear) turn at a constant rotational speed ?
...or will it just block the system due to friction ?
I will rephrase my question: Let's suppose it is a autolocking worm gear, how can I calculate how much M2 needs to be for the mass to lower at a constant speed ?
