where m is the module and N is the number of teeth.

cap F sub u equals open paren m cross g cross mu close paren plus open paren m cross a close paren : Mass of the load (kg) : Gravity ( : Coefficient of friction of the guide system : Desired acceleration ( m/s squared Pinion Torque ( The rotational force the motor must provide at the pinion. cap T equals cap F sub u cross d over 2000 end-fraction : Torque (Nm)

d=z×m=20×2=40 mmd equals z cross m equals 20 cross 2 equals 40 mm Step 4: Calculate Required Motor Torque rack and pinion calculations pdf

Ftotal=(M×a)+(μ×M×g)cap F sub t o t a l end-sub equals open paren cap M cross a close paren plus open paren mu cross cap M cross g close paren where m is the module and N is the number of teeth

Friction: The weight of the load multiplied by the coefficient of friction of the guide rails.

For vertical applications, the formula accounts for gravity: Share public link Ftotal=(M×a)+(μ×M×g)cap F sub t o

To ensure the teeth do not shear under load, the Lewis bending stress formula is used as a baseline evaluation.
