Rokee is a Brake Drum Geared Coupling Manufacturer from China, design & custom-made brake drum geared coupling with reasonable price and high-end quality, learn more about disadvantages of brake drum geared 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.

It will promote the reliable connection of reducer shaft and drum and it is the most ideal product in the market home and abroad at present.

RWC series drum coupling is a type of high-performance drum coupling developed by us and mainly applied for port lifting and large mechanical lifting. In comparison with international DC series products, it has identical outline and connection size, but its interior design is more thorough and steady. The hook face of gear is optimized and the large pressure angle design is applied. A patented mechanism is used for the sealing. One-time filling of lubricating grease is basically free from maintenance, solving maintenance difficulty at heights. In addition, an electronic warning device is set. When the wear life reaches the safe position, the weak current connection will trigger the alarm immediately. It’s a good choice for you!
