Multiple Gears Mechanical Advantage Calculations and Equations

Mechanics and Machines Calculations Menu

Use the following equation to determine the lifting force of the selected spur gear arrangement. Z, Y, X and D are the pitch circles of gears.

F = [ W x r x r1 x r2 ]/[ R x R1 x R2 ]
W = [ F x R x R1 x R2 ]/[ r x r1 x r2 ]
 

Where:

W = Unknown weight
F = Applied force
R = Radius large diameter
r = Radius small diameter
