Pinion Gears are a type of small gear with a small number of teeth that mesh with a larger gear, known as the gear wheel or the gear. They are commonly used in mechanical power transmission systems to transfer rotational motion and torque between shafts, where the pinion is the smaller of the two gears involved in the meshing. These gears are commonly made from materials such as steel, stainless steel, brass, or other alloys, depending on the specific application requirements and load conditions. Pinion Gears are designed to ensure a smooth transition of contact during the meshing process, minimizing noise and impact.
