Ball cage coupling joint is development because the cross shaft coupling or drum tooth coupling are limited of usage angle and installation space , they can’t achieve constant speed transmission, to solve these limitation, ball cage coupling joint was developed.
Compare to these traditional coupling joints, the ball cage coupling joint has under advantages：
1. The installation form is not limited, the input shaft and the output shaft can be any space different plane axis, and its layout is flexible.
2. Because of its constant speed, the intermediate shaft has no speed change, so the transmission is smooth.
3. Small additional bending moment: only about half of that of cross shaft universal joint.
4. High transmission efficiency: The transmission efficiency can be approximated as 1, and 0.98 is generally.
At present, the ball cage coupling joint has been widely used in the steel industry of steelmaking, continuous casting, hot rolling, cold rolling and other aspects, but also widely used in metal calendaring, all kinds of straightening for other metallurgical, plate processing equipment transmission system and etc.
We provide R&D, design, produce, sales and after-sale service integration solutions for metal finishing processing line, equipment, and spare parts.
