Question

What is the train value (G) in compound gear train?

(a) G = \(\frac{N6}{N1} = \frac{T1*T2*T3}{T2*T4*T6} \)

(b) G = N6 * N1 = T1+T2+T3+T4+T6

(c) G = N6 – N1 = T1 * T2 * T3 * T4 * T6

(d) G = \(\frac{N1}{N6} = \frac{T2*T4*T6}{T1*T2*T3} \)

The question was posed to me at a job interview.

My question is from Power Transmission System in section Ignition and Power Transmission of Farm Machinery

Answer 1

Right option is (a) G = \(\frac{N6}{N1} = \frac{T1*T2*T3}{T2*T4*T6} \)

Best explanation: A system of gears which transmits motion from one shaft to another is known as a gear train. When there is more than one gear on a shaft, then, it is called a compound train of gear.
