A countershaft in a machine has two pulleys mounted on it for power transmission and is supported by cylindrical roller bearings at the ends
A countershaft in a machine has two pulleys mounted on it for power transmission and is supported by cylindrical roller bearings at the ends. The countershaft runs at 1,500 revolutions per minute. The belt tension on the loose side of Pulley B is 20% of the tension on tight side.
Design the shaft, mounting components. The design will include the following items.
(1) Shaft material selection based on strength and cost considerations. (Give a comparison b/w at least two possible materials)
(2) Shaft diameters at critical locations along the shaft (using a factor of safety of 1.5)
(3) Selection and design of the components needed for mounting the shaft and bearings
