What is Pinioning?

Pinioning is a process of reducing the number of teeth on a gear or a pinion, which is a small gear that meshes with a larger gear called a ring gear. The purpose of pinioning is to reduce the speed of a machine or a mechanism while maintaining the torque output.

Pinioning is commonly used in transmissions, where it is used to step down the speed of the input shaft while maintaining the torque output. This allows the transmission to provide a range of gear ratios for different driving conditions.

In a pinioned gearbox, the pinion gear meshes with the ring gear, and the number of teeth on the pinion gear is less than the number of teeth on the ring gear. This creates a speed reduction between the input shaft and the output shaft, which allows the transmission to provide a higher torque output at lower speeds.

Pinioning can also be used in other applications such as in wind turbines, where it is used to step down the speed of the main shaft while maintaining the torque output. This allows the wind turbine to operate more efficiently and generate more power.

In summary, pinioning is a process of reducing the number of teeth on a gear or a pinion to reduce the speed of a machine or a mechanism while maintaining the torque output. It is commonly used in transmissions and other applications where a speed reduction is required while maintaining a high torque output.
