Gear Couplings (GICL & GICLZ Series)
The gear coupling is referred to as a modified version of the flange coupling, which can transmit high torque due to the larger size of the teeth. In these types of shaft coupling, the flanges as well as the hub are found to be assembled separately together instead of any single part as a flange coupling.
During its construction, each joint is found to have a 1:1 gear internal ratio along with an external gear pair. And gear coupling is found to be limited to angular misalignments of around 0.01-0.02 inch in parallel as well as in 2 degrees angular. Gear couplings, as well as universal joints, are the ones that are found to be used for similar applications. These are those couplings which are mostly used in heavy-duty applications where the torque transmission is found to be required to be the highest.
Gear Couplings are heavy-duty flexible couplings designed to transmit high torque between two shafts while accommodating angular, parallel, and axial misalignments. Featuring internal ring gear sleeves meshing with crowned external gear hubs, they offer compact radial dimensions and superior load-bearing capacity compared to traditional flexible couplings. Gear couplings require grease or oil lubrication during operation and are widely used in heavy industrial machinery, metallurgy, cranes, and marine drives.
Key Features & Advantages
- Crowned Tooth Profile: Curved drum-shaped teeth improve contact stress distribution and increase angular misalignment compensation (up to 1.5°).
- High Torque Density: Compact design delivers maximum torque transmission in restricted radial spaces.
- Heavy-Duty Reliability: Forged steel hubs and high-tensile sleeves ensure long service life under high shock loads.
- Standardized Models: Full range of GICL (standard broad type) and GICLZ (intermediate shaft/extended type) sizes available.
Type GICL Gear Coupling Specifications
Type GICL is designed for connecting two horizontal coaxial shafts with standard end-gap distance.
Type GICLZ Gear Coupling Specifications
Type GICLZ features an extended sleeve design suitable for applications where the distance between the two connected shaft ends is longer. Nominal torque ranges from 800 N.m to 3,200,000 N.m, operating within ambient temperatures from -20°C to +80°C.
