The variable tension pulley system including a drive pulley, a slave pulley, a belt interconnecting the drive pulley and slave, a tensioner assembly positioned between the drive pulley and the slave pulley and in engagement with the belt. The tensioner assembly includes an elongated rack, a drive...
In summary, the tension in each line of a pulley system is equal when the pulleys are massless and frictionless. This is due to the rule of thumb for block and tackle, where the mechanical advantage is equal to the number of ropes supporting the bottom pulley. By making a free body ...
tension pulley[′ten·chən ‚pu̇l·ē] (mechanical engineering) A pulley around which an endless rope passes mounted on a trolley or other movable bearing so that the slack of the rope can be readily taken up by the pull of the weights....
the distance between the axles is small or the transmission ratio is high. Tension rollers should be installed on the driven side of the belt near the small pulley. The disadvantage of transmissions with tension rollers is a decrease in the service life of the belt because of additional ...
There are some great design elements in this one, not least being the way tension is controlled by measuring the movement of an idler pulley using a linear pot. At top speed, the machine looks like it complete a coil in just about three minutes, which seems pretty reasonable with such nea...
