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.

Question 1: A team of engineers from the Department of Mechanical Engineering are task to design a hoist equipment using a reverted epicyclic gear train shown in Figure 1. The drum must be keyed at the centre of the arm E using the same shaft. The pinion gear A is keyed to a second shaft which carries a chain wheel. Whereas the chain must be operated by hand. The two shafts have common axis but can rotate independently. The gear wheels B and C are compound and rotate together on a pin carried at the end of arm E. The gear wheel D has internal teeth and is fixed to the outer casing of the block so that it does not rotate. The wheels A and B have 16 and 36 teeth, respectively, with a module of 3 mm. The wheels C and D have a module of 4 mm. D- B E A- Figure 1: Top view of a reverted epicyclic gear train. 1.1. Draw the side view layout of the gear system to be designed.
