Calculation of Gearbox the frequent change in the speed

The frequent change in the speed where the output is required, we used the two speed gearbox. Aim of the report is to design the 4 speed 2 stage gearbox by using the spur gears where the transmission is highly efficient, that keep the gear box so economically feasible. There are so many calculations and the verifications which places to justify the success of designs. Important function of the gearbox is to transmit the power which required the output for the element by changing source of input power. [1]

Design of Gearbox for the frequent change in the speed

Power transmitted: -0.340Kw

Minimum output speed: -1100 rpm

Maximum output speed: -3400 rpm

Motor speed (input): -3000rpm

Number of speed steps: -4

Power speed, 2 speed of gearbox by loss optimized direct drive

i: 1-5.5

Geometric Progression ratio of Gearbox for the frequent change in the speed

Now the above equation, we obtained 2 stages of gearbox, by each stage of 2 speed steps.
