अवधारणा:

गियर ट्रेन का गति अनुपात (या वेग अनुपात):

  • गियर ट्रेन का गति अनुपात (या वेग अनुपात) चालक की गति का चालित या अनुगामी की गति का अनुपात है।

गति अनुपात  = \(\frac{N_{driver}}{N_{driven}}=\frac{N_{1}}{N_{2}}=\frac{T_{2}}{T_{1}}\)

जहां Nऔर  T गियर की गति और दांत हैं।  T2 और  T1 चालित और चालक गियर पर गियर के दांतों की संख्या हैं।

गणना:

दिया गया:

T1 = 24, T2 = 8

N2 = 36

गति अनुपात\(\frac{N_{driver}}{N_{driven}}\) = \(\frac{N_{1}}{N_{2}}\) = \(\frac{T_{2}}{T_{1}}\)

⇒ \(\frac{N_{1}}{N_{2}}\) = \(\frac{T_{2}}{T_{1}}\)

⇒ \(\frac{N_1}{36}~=~\frac{8}{24}\)

⇒ N1 = 12
