1. Gear Ratios
Gear ratios are fundamental to the functionality of a portal gear reduction calculator. These ratios, expressed as the relationship between the number of teeth on interconnected gears, determine the speed and torque transformation within a portal gear system. A higher gear ratio results in a lower output speed but a proportionally increased output torque. This relationship is crucial because it allows engineers to tailor the output characteristics of a system to specific application requirements.
