One rotation of the spur gear will displace the rack l one circumferential length of the gear's reference circle,per the formula : The rack displacement, l, is not changed in any way by the profile shifting.

What is a rack and pinion ? A rack and pinion are used when converting rotational movement to linear motion (or vice versa). A bar shaped gear with an infinite (flat surface) radius of a cylindrical gear is called a rack, and a meshed spur gear is called a pinion.
A spur gear differential is constructed from two identical coaxial epicyclic gear trains assembled with a single carrier such that their planet gears are engaged. This forms a planetary gear train with a fixed carrier train ratio R = −1.

Whether for versatile solutions from the modular system or for customer-specific solutions in large-scale production: ebm-papst has been the system supplier for small and industrial motors for decades.
A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage.. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next.
Understanding Motor and Gearbox Design - Instructables
Now that you understand the specifications that distinguish motors, you can work on choosing a motor and gear ratio for your application. Which motor is most appropriate for a given job is entirely dependent on the application's requirements.
