This is the heart of the system. The linear force (N) generated by a pinion torque T (Nm) is: F = (T × 2000) / d where d is pitch diameter in mm.

The distance between corresponding points on adjacent teeth. $$P = \pi \times m$$

Before calculating forces, you must define the physical geometry of the gear teeth and pitch lines. Key Nomenclature Module ( rack and pinion calculations pdf

To select the correct material and tooth size, you must determine the required to move the load. Rack and Pinion Drive Calculations and Selection

A good PDF provides tables for backlash versus module and quality grade (Q5 to Q12).

You can find the speed of the rack if you know how fast the pinion spins in RPM ( Ftotal=(Fu+Fa+Ffriction)×Sfcap F sub t o t a l

Rack Pitch Line Height (Hp)=Total Rack Height −mRack Pitch Line Height open paren cap H sub p close paren equals Total Rack Height minus m 2. Imperial Calculations (Based on Diametral Pitch)

Fs=Ft×tan(α)cap F sub s equals cap F sub t cross tangent open paren alpha close paren 4. Strength and Durability (Lewis Formula)

) must not exceed the allowable yield strength of the chosen material. The distance between corresponding points on adjacent teeth

Torque is the rotational equivalent of linear force. It is the pinion's rotational force and can be calculated as:

Comprehensive Guide to Rack and Pinion Calculations: Theory, Formulas, and PDF Resources

Circular Pitch (p)=π×mCircular Pitch open paren p close paren equals pi cross m

Use this formula to find out how big your electric motor needs to be.
