We are familiar with the requirements from several projects in the field of mechanical engineering and have the necessary experience to find the right solution for you. By kinematical arguments, the gear ratio is equal to pitch radius of the pinion: $\frac{v_R}{\omega_P}=r_P$)Anyways, a power balance argument can be used to show how the mechanical advantage depends on the gear ratio.
Gear $o$ is connected via gearshaft to the pinion (of the rack and pinion set) ($T_o=T_P$, $\omega_o=\omega_P$).So the drivetrain has gear ratio of $G=\frac{\omega_P}{\omega_i}=\frac{T_i}{T_P}$.

Two years ago Logical, One year … While much of the terminology in engineering and automation is standardized, some words are still widely misused, especially when different terms apply to similar principles. February 17, 2017 By Danielle Collins 2 Comments. It only takes a minute to sign up.I'd like to know if I can use a gear train to drive a pinion, and thereby increase the torque of the rack.

Let’s consider a pinion driving a rack: (excuse the rough drawing)Assuming 100% efficiency, the power into the pinion is equal to the power out of the rack. Mechanical engineering combines creativity, knowledge and analytical tools to complete the difficult task of shaping an idea into reality. Notice that if we multiply the gear ratios of the drivetrain and rack-pinion set together we get:Or, rearranging, the force on the rack is given by:So with gear $i$ as the input to the overall system, and the rack as the output, you can see how the gear ratio $G$ of the geartrain does indeed contribute to the mechanical advantage of the pinion-rack gearset.As for the second part of your question, I’m afraid I can’t help much without seeing any sort of diagram of the configuration of the gearing.There is a direct correlation between any gear system input and output. Project example dynamic simulation. Note how rearranging provides a relationship between mechanical advantage and gear ratio:(Note how it is possible to derive a corresponding expression for cases with efficiency below 100% by modifying the power balance argument: $T_P \omega_P\eta = F_R v_R$)As for how this all fits in with a drive train connected to the pinion, let’s suppose the drivetrain starts with gear $i$ (which has torque $T_i$ and angular speed $\omega_i$) and ends with gear $o$ ($T_o$, $\omega_o$).

That is:Where $T_P$ is the pinion torque, $\omega_P$ the pinion angular speed, $F_R$ the rack force and $v_R$ the rack translational speed.
