Gear train efficiency.

thread406-427408

Gear train efficiency.

Gear train efficiency.

(OP)

Hi all,

I need help deriving an equation for the efficiency of the gear train in terms of the output torque.

This train has fixed losses, input power, input and output speeds.


Any guidance welcome.

RE: Gear train efficiency.

GSXR-750,

η=OUTPUT POWER/INPUT POWER

You have provided us no other information.

RE: Gear train efficiency.

(OP)
Sorry. I also have

efficiency = (Torque Output x Rpm output)/(Torque input x Rpm in) x 100


My gear train has 4 gears.
Input speed is 100rpm and output 400.
Input torque is 860.96 Nm.

RE: Gear train efficiency.

GSXR-750,

Torque times speed is power. When you multiply by 100, you can a percentage instead of a fraction.
