Application Analysis of YHTJ Ball Cage Universal Coupling in 11-roller Straightening Machine.

Technical advantages of YHTJ ball cage universal coupling
(1) High angle compensation capability
Large deflection angle: The deflection angle of a single section can reach 15°~25°, which can adapt to the axis deflection caused by adjustment or deformation of the roller system of the straightening machine, and avoid bearing overload caused by rigid connection.

Multi-directional compensation: Compensate for radial, axial and angular deviations at the same time, reducing the installation accuracy requirements.

(2) Efficient torque transmission
Constant speed transmission: The ball cage structure ensures synchronous rotation of the input/output shaft, avoiding the influence of speed fluctuation on the straightening accuracy (traditional cross universal joints are prone to speed fluctuations).

High load-bearing capacity: The high-strength alloy steel and precision ball track design are used to meet the large torque requirements of the straightening machine (such as the hot rolling line torque can reach tens of thousands of Nm).

(3) Impact resistance and long life
Load-balanced design: Multiple steel balls share the load, reduce local stress concentration, and extend service life.

Wear resistance: Surface hardening treatment (such as carburizing and quenching) and grease seal design are suitable for high-frequency start-stop conditions of the straightening machine.
