Thats a very good point. I will have to check the positioning of the pipe at start of the operation. If memory serves me correct, the pipe starts off with a longer section protruding further over the drive end.
If you imagine the rollers as 3 x driven then 2 x non driven, and the pipe will be...
"Do you mean that the 5 rollers are in the same plane and their axes are at right angles to the pipe axis."
Yes this is correct.
So this is what I have so far, and please correct me if I am wrong:
Known Variables:
M = 3000 kg
rotational Speed = 4.338 rads/sec
radius of contact = 0.0937 m...
Thanks zekeman
So I take it from there it would be a simple case of Torque = F.r
I did get a bit lost when you were talking about 2 rollers at 45 degrees though.
If you are looking at the system side on, the five rollers are horizontal and the length of the pipe sits along the top of them.
I have a problem with calculating the required torque to be applied to rollers to move a pipe horizonally.
The pipe sits on 5 rollers, three of which are to be driven by gear motors. The radius of contact between the centre of the rollers and the pipe is 93.7 mm, and the mass of the pipe is...
