A standard V-belt with \(\beta=18^{\circ}\) is used with a motor pulley of 40 -mm pitch diameter and a flat cylindrical drum of \(120-\mathrm{mm}\) diameter. Center distance is \(120 \mathrm{~mm}\). What is the approximate relationship between the slip-limited power transmission capacities at the pulley and at the drum?
Write several paragraphs describing the difference between modular belting, mat top chains, flat top chains, and table top chains.
A single V-belt with \(\beta=18^{\circ}\) and unit weight of \(0.012 \mathrm{lb} / \mathrm{in}\). is to transmit \(12 \mathrm{hp}\) from a 1750 -rpm, 6 -in.-diameter driving pulley to a 12 -in.-diameter driven pulley. Center distance is to be \(20 \mathrm{in}\). (a) On the basis that the coefficient of friction is \(0.20\) and the initial belt tension is just adequate to prevent slippage, determine the values of \(P_{1}\) and \(P_{2}\). (b) Determine the torsional and resultant radial loads applied by the belt to each of the shafts. (c) Determine values of \(P_{1}\) and \(P_{2}\) when the drive is operating at normal speed but transmitting only \(3 \mathrm{hp}\).
A single V-belt with \(\beta=18^{\circ}\) and a unit weight of \(2.2 \mathrm{~N} / \mathrm{m}\) is to be used to transmit \(12 \mathrm{~kW}\) from a 1750 -rpm, 180 -mm-diameter driving pulley to a 1050 -rpm driven pulley. Center distance is \(400 \mathrm{~mm}\). (a) On the basis that the coefficient of friction is \(0.20\) and the initial belt tension is marginally adequate to prevent slippage, determine the values of \(P_{1}\) and \(P_{2}\). (b) Determine the torsional and resultant radial loads applied by the belt to each shaft. (c) Determine the initial belt tension when the drive is not operating. (d) Determine values of \(P_{1}\) and \(P_{2}\) when the drive is operating at normal speed but transmitting only \(6 \mathrm{~kW}\).
