    Conveyor Belt Tension with Sliding Rollers

    Hi dvd, Thanks for your reply. Just to check, you say it's a vector sum, so: Fp = T (1 + sina) Fq = T (sinb - cosa) Leading up to Fp = Fq (1 + sina) / (sinb - cosa) Is this what you mean? Take R as the driver rotating clockwise. That means T1 > T2 (new diagram). From my studies, T1 and...

    Conveyor Belt Tension with Sliding Rollers

    In this conveyor belt configuration, rollers P and R are horizontally aligned, while rollers R and S are vertically aligned, in a triangular arrangement. Roller Q then bends the belt between P and S. Roller Q is free to slide vertically, while roller P slides horizontally. The remaining rollers...

    Motor Sizing for a Heavy and Slow Belt Drive

    Hi desertfox, That was a typo. I did divide by the radius to obtain tangential forces. To dvd and other readers, I've attached a diagram. However, the inclination is not indicated as I have no information on that; in my approach, this was not required (please correct me if I am wrong)...

    Motor Sizing for a Heavy and Slow Belt Drive

    Hi everyone, I would like some validation on my calculations of the required torque and power for a motor to drive a heavy but slow conveyor belt assembly. I feel that I may have underestimated these values significantly. Method of driving: Motor pinion drives a large roller via a internal...
