A detailed introduction of coaxial gearbox- Shanghai SGR Heavy Industry Machinery Co., Ltd.

In the world of industrial power transmission, gearboxes play a crucial role in adjusting torque and speed to meet application-specific demands. One of the most reliable and compact gearbox solutions is the coaxial gearbox, known for its high efficiency and versatile design.

In this article, we’ll take a closer look at what a coaxial gearbox is, highlight why it’s one of SGR's core products, and explore the wide range of industries that benefit from this powerful mechanical solution.

(1) What is a coaxial gearbox?

A coaxial gearbox, also referred to as an inline gearbox, is a type of gear reducer where the input and output shafts are aligned on the same axis. This alignment allows for a compact design, efficient power transmission, and easy integration into various machinery setups.

This design also contrasts with other configurations like right-angle planetary gearboxes, where the input and output shafts are perpendicular to each other. The coaxial arrangement is achieved by placing the sun gear, planet gears, and ring gear in such a way that they all rotate around the same central axis.The key features of a coaxial gearbox include:

inline shaft arrangement.This design simplifies alignment during installation and ensures smooth torque transmission without the need for complex mounting structures.
Compact Structure.By aligning the input and output along the same axis, these gearboxes can fit into tighter spaces compared to other types.
Smooth Operation.Even load distribution ensures smooth and reliable operation, making it ideal for demanding applications.
High torque density – Due to the planetary gear mechanism, coaxial gearboxes can deliver substantial torque in a relatively small footprint, making them ideal for space-constrained applications.
Superior efficiency – With minimal energy loss during transmission, coaxial gearboxes often reach efficiency levels up to 97%, reducing energy consumption over time.
Low backlash – The precise meshing of planetary gears helps maintain positioning accuracy, which is essential for automation and motion control systems.
Modular design.Many coaxial gearboxes, such as those offered by SGR, support various mounting options and input/output configurations, allowing for flexible integration across industries.
