Gear Couplings

A gear coupling is a high-torque mechanical connector for non-collinear shafts, using internal/external gear teeth in sleeves to transmit power while compensating for angular, radial, and axial misalignment, making it ideal for heavy industrial uses like steel mills, pumps, and conveyors where high power density and reliability are crucial, though it requires proper lubrication and maintenance for longevity. 

How it works

Components: Two hubs (with external gear teeth) attach to each shaft, connected by sleeves (with internal gear teeth).

Misalignment Compensation: The gear teeth allow for movement, flexing to handle angular (side-to-side), radial (offset), and axial (end-to-end) misalignment between shafts.

Torque Transmission: High surface contact between the crowned gear teeth provides efficient, high-torque power transfer with exceptional torsional stiffness. 

Key Features & Benefits

High Torque: Capable of handling very high torque loads.

Compact: Offers a high power-to-weight ratio, fitting into tight spaces.

Reliable: Provides long service life with proper lubrication.

Versatile: Available in various configurations (single/double engagement, rigid/flexible halves) for different needs. 

Applications

Roll drives (steel, paper industries)

Pumps, fans, conveyors

Power generation equipment 

Maintenance

Requires periodic lubrication (grease) to protect the gear teeth.

Proper alignment during installation is critical for reliability and longevity.
