What Is A Coaxial Gearbox?

A coaxial gearbox, also known as an in-line gearbox, is a type of mechanical gearbox configuration where the input and output shafts are aligned and share the same axis of rotation. The term "coaxial" refers to the fact that the input and output shafts are positioned concentrically, with one shaft surrounding the other.

In a coaxial gearbox, the input shaft is typically driven by a power source such as an electric motor or an internal combustion engine. The rotational motion from the input shaft is transmitted to the gearbox, where it undergoes various gear reductions and changes in torque and speed. Finally, the output shaft, which is coaxial with the input shaft, delivers the desired output motion or power.

Coaxial gearboxes can incorporate different types of gears, such as spur gears, helical gears, bevel gears, or worm gears, depending on the specific application and design requirements. The gears inside the gearbox mesh together to transmit torque and rotational motion from the input shaft to the output shaft. By using different gear ratios and gear arrangements, coaxial gearboxes can provide a wide range of speed reductions or increases, allowing for the optimization of torque and speed for various applications.

These gearboxes find applications in a variety of industries, including automotive, manufacturing, robotics, and industrial machinery, where precise control of torque and speed is required. They are commonly used in applications such as conveyors, machine tools, pumps, and power transmission systems where the input and output shafts need to be in alignment for efficient power transfer.
