The girth gear is the larger component in a gear pair, typically functioning as the driven wheel. Its primary role is to reduce output rotational speed while simultaneously increasing output torque, thereby providing substantial power to the equipment.
The driven pinion drives the ring gear. According to the gear ratio (number of teeth on the ring gear divided by number of teeth on the pinion), the pinion must rotate multiple times before the ring gear completes a single revolution. This achieves a reduction in rotational speed and a multiplication of torque.
Large dimensions, substantial weight, and high inertia.
Primarily used in equipment requiring low-speed, heavy-duty power transmission:
