Answer / phani

N2/N1=T1/T2

here N1= Drive speed
N2= Driven speed
as well as T1= Drive Gear Teeth
T2= Driven gear Teeth

Ex: Gear Ratio is 1:8
this means if the drive N1 rotates with 1000rpm, the driven
speed is 8000rpm.

Answer / karthick

i think speed ratio is otherwise called as gear ratio.gear
ratio can be determined by the following equation:

N2/N1=T1/T2

T1-no of teeth present in driving wheel
T2-no of teeth present in driven wheel
N1-speed of the driving wheel
N2-speed of the driven wheel

Answer / manik singh

gear ratio is also called as speed ratio.

G.R= N1/N2= T2/T1

N1= Speed of the driving wheel.
N2= speed of the driven wheel.

T1= no. of teeth on driving wheel.
T2= no. of teeth on driven wheel.

Answer / ravi gupta

gear ratio is defined as the ratio of least no of teeth on
gear to the least no. of teeth of pinion.
G=T/t
T=no.of teeth on gear
t=no.of teeth on pinion

Answer / pjagan89

Gear ratio is defined as the ratio of number of teeth on the
gear to the number of teeth on the pinion.

G= T/t
T- Number of teeth on the gear.
t= number of teeth on the pinion.

Answer / csk

N2/N1=T1/T2

here N1= Drive speed
N2= Driven speed
as well as T1= Drive Gear Teeth
T2= Driven gear Teeth

Ex: Gear Ratio is 1:8

speed is 8000rpm.

Answer / mohan

no.of teeth in driven by no. of teeth in drive

G.R=N2/N1

Answer / ayan

Gear ratio is the ratio of number of teeth in driving wheel to number if teeth in driven wheel.
G.R=N1/N2 -
where N1=number of teeth in driving wheel
N2=number if teeth in driven wheel.

Answer / vickram

CAN N1/N2 = T2/T1?????????

HERE T2= DRIVEN TORQUE
T1 = DRIVE TORQUE
N1= Drive speed
N2= Driven speed

CAN ANY TELL PLS..

plz anyone provide me the sample test papers of ONGC as of i m from Mechanical engg bakground and would be appearing for the test in the june 2010. My email id - neeraj_94312@rediffmail.com
