Tangential Drive Formulas

Torque required to drive load W using a tangential drive such as a conveyor or timing belt drive

 

Ttotal=TLoad+TPulley+ TBelt+TMotor+ TFriction

Tfriction=FR

Ttota=1/g(Jload+J-Pulley+JBelt+ JMotor)w/t+ TFriction

Jload=WLR2

JPulley=(WrR2)/2  (Multiply by the total number of pulleys)

JBelt=WBR2

W=V/R

 

T=Torque, oz-in

w=angular velocity, radians/sec

t=time, seconds

WL=weight of the load (oz)

WP=pulley weight (oz)

WB=Belt weight (oz)

R=radius, inches

r=density, ounces/in

g=gravity constant 386in/sec2

V=linear velocity, in/sec

F=frictional force (oz)
