Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

developed by the motor, gear B removes of the power developed by the motor, and gear C removes of
the power developed by the motor. The drive shaft is fabricated from an alloy steel with a yield strength in
shear of 19 ksi. Determine the minimum acceptable shaft diameter dmin that satisfies the below constraints:

The crude-oil pumping rig shown is driven at 20 rpm. The inside diameter of the well pipe is 2 in., and the diameter of the pump rod is 0.75 in. The length of the pump rod and the length of the column of oil lifted during the stroke are essentially the same, and equal to 6000 ft. During the downward stroke, a valve at the lower end of the pump rod opens to let a quantity of oil into the well pipe, and he column of oil is then lifted to obtain a discharge into the connecting pipeline. Thus, the amount of oil pumped in a given time depends upon the stroke of the lower end of the pump rod. Knowing that the upper end of the rod at D is essentially sinusoidal with a stroke of 45 in. and the specific weight of crude oil is 56.2 lb/ft3 determine (a) the output of the well in ft3. /min if the shaft is rigid, (b ) the output of the well in ft3 /min if the stiffness of the rod is 2210 N/m, the equivalent mass of the oil and shaft is 290 kg, and damping is negligible.

The max speed for the servo shown is 130RPM when connected to 6V. Assume that the gearbox on your servo is able to output a torque of 1.5 kg-cm while turning at this speed. Using the number of teeth on each gearprovided in the table, determine the torque and rotational speed of the output shaft on the DC motor. HINT: Work backwards from the output shaft and use the equations developed in class that relate the number of teeth to the torque. When working back from the output shaft to gear 7/6, realize that the “torque” transmitted by gear 7 is the SAME as the torque transmitted by gear 6 since they are joined. Then, relate the torque of gear 6 to gear 5 based on their numbers of teeth. Since gears 5 and 4 are actually one piece, the torque in 4 and 5 will be the same (as was the case for gears 6 and 7). Repeat for the other gears, working your way all the way back to the DC motor.
In the pulley system shown in the figure, while the P gear rotates in the direction of 1 with its angular velocity, find the direction and angular velocity values of the other gears.

Two shafts 10 ft apart, with axes in the same horizontal plane, are to be connected with a flat belt in which the driving pulley, powered by an electrical motor with a 25 hp rating at 900 rev/min, drives the second shaft at half its angular speed. The driven shaft drives uniform (smooth) machinery loads. Select a flat belt.
