Transcribed Image Text:
A concrete mixer drum shown in Figure I is powered using an electric motor with a comblned transmission system. The system consists ofa rigid coupling, a flat belt drive, a pair of spur gears and a bevel gear drive. The total transmission ratio of the system is i 25. The mixer drum is rotating at a speed of no-100 rpm. The torque required to move the drum is 344 N.m. The total efficiency of the transınission system is 0.9. Calculate: a. The motor power and speed. b. inea If the transmission ratios of the individual systems are: bevel (-5) spur (42.5). flat belt (la-2) find L.
