Barrel Gear Couplings

Barrel gear coupling is a widely used mechanical transmission component that plays a vital role in connecting two rotating shafts and transferring torque efficiently across industrial drive systems. Its unique structural design features barrel-shaped external teeth that mesh closely with internal teeth of the outer sleeve, forming a stable and durable transmission structure that stands out from conventional coupling types. This specialized tooth profile not only ensures smooth power delivery but also delivers exceptional adaptability to various shaft misalignments, including angular, parallel and axial deviations, which effectively reduces additional stress caused by installation errors or operational deformation, protecting both the coupling itself and connected equipment from premature wear and damage.

China National Drum Gear Couplings

The drum gear coupling is a specially designed advanced gear coupling. Its outer teeth are made into a sphere, with the center of the sphere on the axis of the gear. The teeth clearance is slightly larger than the general products and can transfer a greater torque and allow greater angular displacement, enjoying excellent performance and longer life.

ROD Series Crown Gear Coupling

ROD crown gear coupling is one of the transmission products with core technology independently developed by Rokee and has established and reported corporate technical standards in the country. By combining with the standard coupling technology of advanced countries such as Japan and Germany, we optimized many detailed dimensions, and adopted the toothed design with a large pressure angle and short shaft design for the shaft hole, which reduces the length-diameter ratio, and has a more compact structure and excellent speed performance. The bolts of similar types are standardized and the parts are universal. Compared with the national standard couplings, our standard couplings can transfer more torque, with greatly reduced mass and small moment of inertia. It meets the European explosion-proof requirements and the comprehensive performance is greatly advanced. We highly recommend you to choose our products for better transmission performance.

National Standard Couplings

Rokee can provide you with almost all of the national standard couplings. Our years of technological accumulation and progress ensure that we can better comply with the technical requirements of national standards, design and manufacture common standard products to meet customer expectations and specifications. Also, our abundant technology reserves ensure that your selection and procurement requirements of couplings, whether rigid, flexible, safe, large or small, are met immediately within most national standards.
