GICL Type Drum-type Gear Coupling

The GICL drum gear coupling is a heavy-duty power transmission component specifically designed for low-speed, high-torque, and complex operating conditions. It is widely used in industries such as metallurgy, mining, lifting and transportation, and heavy machinery, where it plays a critical role in ensuring stable connections and reliable torque transmission within industrial drive systems. While achieving efficient torque transfer, this coupling also provides excellent compensation for axial, radial, and angular misalignment. In particular, under conditions involving relatively large axial displacement, it can effectively reduce additional loads on the shaft system, thereby enhancing the operational safety and service life of the entire equipment.
The core structure of the GICL drum gear coupling consists of an external-tooth sleeve and an internal gear hub, with its defining feature being the use of a crowned tooth design on the external gear. Compared with conventional straight-tooth structures, the crowned teeth are machined with a spherical profile, with the center of the sphere coinciding with the coupling axis, and an optimized tooth side clearance is provided. This design allows the tooth surfaces to maintain good contact even in the presence of installation misalignment or operational deformation. As a result, the meshing conditions are significantly improved, the load is more evenly distributed across multiple teeth, and tooth surface wear as well as local stress concentration are effectively reduced, thereby enhancing the coupling’s reliability under heavy-load and impact operating conditions.
