Gear Couplings: Reliable Solution for Heavy-Duty Industrial Transmission

Gear couplings consist of an internal gear ring with the same number of teeth and a flanged half-coupling with external teeth. The external teeth come in two types: straight teeth and spherical teeth. Spherical teeth are formed by making the external teeth spherically, with the center of the sphere on the gear axis. The tooth flank clearance is larger than that of ordinary gears. Spherical gear couplings allow for larger angular displacements (compared to straight gear couplings), improving tooth contact conditions, increasing torque transmission capacity, and extending service life.

During operation, the two shafts undergo relative displacement, and the Gear couplings surfaces of the internal and external teeth periodically slide axially relative to each other, inevitably resulting in tooth surface wear and power loss. Therefore, gear couplings must operate under conditions of good lubrication and sealing.

When your equipment faces high torque, intense vibration, and continuous heavy loads (mining crushers, conveyor systems, heavy machinery), the gear couplings for Extreme Industrial Environments is the reliability you need.

The gear couplings are engineered for:

✅Exceptional load-bearing capacity (handles the high torque)

✅ Superior angular/axial misalignment compensation (up to 1.5°)

✅ Wear-resistant alloy steel gears + sealed structure (dust proof, waterproof, extended service life)

✅ High-precision gear meshing (minimizes transmission loss, ensures smooth operation at 3000+ rpm)

✅ Corrosion-resistant & heat-treated components (adapts to -40°C~120°C extreme temperatures)

✅ Long service life (50,000+ hours of trouble-free operation—2x longer than standard couplings)

How to choose the gear couplings, you can have a reference on those steps:

✅Determine the torque transmitted by the coupling (including impact load and safety factor)

✅Adapt to the maximum speed of the equipment and avoid critical speed;

✅Select the structure according to the type of installation deviation (angular / axial / radial);

✅Check the shaft diameter and installation space dimensions;

✅Select the material according to the working conditions (wear-resistant / corrosion-resistant / high-temperature resistant, etc.);

✅Confirm the sealing and lubrication methods (grease / oil lubrication)
