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)
