Rokee is a Toothed Coupling Manufacturer from China, design & custom-made toothed coupling with reasonable price and high-end quality, learn more about laminated toothed coupling information, please email us, Rokee's technical engineer will reply as soon as possible.
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 Curved-tooth 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 Toothed 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 Crown Gear Couplings for better transmission performance.
