Universal joint couplings are commonly known as universal joint shafts. One of many structural designs of universal joint shafts, swc series universal joint shafts is the most commonly used with the highest load capacity. drawing on our 15 years of engineering experience and the advanced world technology, we have conducted in-depth research on the swc series universal joint shafts product line. Our product have far surpassed the chinese jb5513-91 engineering standards both in performance and product variety and are able to satisfy our customersâ�� diverse and stringent requirements. In particular , our ultra-short hollow universal joint shaft was patent licensed for its functional innovations. our product range consists of the following 4 series, covering a torque range of 180~8, 000, 000n .m, with swc series as the core product line. 1. Swc-i series-light-duty design - nominal torque tn=180~32, 000n.m - joint diameter d=52~225mm - maximum deflection angles ã�=25â° and 35â° 2. Swc series-medium-duty design - nominal torque tn=18~1000kn.m - joint diameter d=160~620mm - maximum deflection angles ã�=15â° 3. Swcz series-heavy-duty design - nominal torque tn=1250~8000kn.m - joint diameter d=620~1200mm - maximum deflection angles ã�=5â° and 10â° 4. Swcd series-short-design - nominal torque tn=25~90kn.m - joint diameter d=215~350mm - maximum deflection angles ã�=5â° our relentless efforts towards perfection of designs and technical innovation have enabled us to manufacture universal joint products with outstanding features and performance, and with a quality level that is second to none in china. Our product strengths include: prolonged bearing life: the efforts towards perfection of sealing system and imported sealing fittings for cross assemblies to ensure an optimal lubricating condition for a prolonged bearing life. superior machining precision: spline sets are precision machined with a unique hobbing-broaching process and the spline surface are treated with hardening process so that the accuracy and stability of spline fit are greatly improved. The customer can choose between involute and rectangular tooth profiles for the splines. optimal balancing quality: on the strength of our thorough research on vibration engineering, state-of-the-art manufacturing technology and complete dynamic balancing testing methods, all the universal joint products manufactured by us meet the balancing grade of g40, which is well above our customersâ�� balancing requirements of g16. some of our satisfied clients: lloydsâ�� steel industries, nagpur, india. maharashtra seamless, india.

Gear couplings are transmission components that are extensively used on mechanical equipment. As china becomes increasingly globalized and the level of chinese equipment becomes more advanced, the national and international market demands higher quality gear couplings. The satisfy market needs, wuxi driveshafts has taken on a research project in 2005 to develop crowned tooth gear couplings. Over the years, we have analyzed both domestic and foreign industrial standards and have completed extensive research and testing in areas of mechanical properties, structural designs, manufacturing methods and equipments, as well as production organization. Our gear coupling products have been trial used and approved by domestic and foreign customers. We now launch the bc crown tooth gear couplings that have the following features: 1. Conformity to national industrial standards of the country in product properties and external connections. 2. Enhanced technical specifications through overall optimization in design. 3. The use of fine allow steel for sleeves and hubs, quenching and tempering treatment. 4. Enhanced strength of tooth surface through nitriding treatment. 5. Precision machining with cnc equipment with perfect tooth blanks and profiles. 6. Perfect alignment through centering via dedendum circle of inner gear and addedendum circle of outside gear. 7. Special design of sealing system and components, which serves to greatly enhance the lubrication effect, a critical element for gear couplings. 8. Bolt holes of sleeve flanges are machined on vertical machine centers with precision that can satisfy the requirement of reamed bolt holes. 9. Automatic sub-arc welding for gear spindles with floating shafts achieving grade ii or better weld strength on ultrasonic flaw detection. 10. All gear spindles with floating shafts leave the company with a balancing accuracy range of grade g16 – g40. If high balancing grade is required, please submit your request. (units to be balanced are limited to 3000kg) in weight and 6500mm in length).

We have been supplying high quality industrial disc couplings for the korean domestic market as well as major industrial countries including japan, china and india. Our products are built to international standards; our factory is iso 9001:2000, tuv (germany), and bv (france) certified and has a firm basis for quality control. our disc coupling features the following: - lubrication is not necessary because of the absence of sliding, frictional, or moving parts. There is no friction or noise, the energy loss is low, and there is no dirty oil to manage. - higher torsional stiffness and no backlash. This is excellent for equipment such as machine tools with numerical controllers, indexing system, and printing machines requiring accruate shaft rotation and phase control. - we also offer fiberglass spacer tubes which are perfectly suited for high-demand operating conditions like electrostatically hazardous environments (windmills and turbines), corrosive environments (water, marine applications), or where minimum weight is a critical criteria. - when properly installed and if initial conditions remain unchanged, our disc couplings have an unlimited service life. Some required maintenance are: i. Visual inspection of the condition of the element(flexible plate) and of bolts and nuts when operation is stopped. ii. Should the element be damaged due to overload or accident, a fall-safe mechanism transmitting rotation via washers kicks in and cuts off operation to minimize damage to surrounding equipment.
