Universal Joint Coupling For Plate Rolling Machine

In the field of modern industrial manufacturing, the rolling machine is an important equipment for metal sheet processing, and the reliability of its transmission system directly affects production efficiency and product quality. As the core component of the transmission system of the rolling machine, the universal joint coupling plays a crucial role in power transmission and angle compensation.

Universal joint coupling is a mechanical device that can transmit torque within a certain angle range, allowing for angular deviation between the two connected shafts while maintaining the continuity of power transmission.

Main types:

1. Cross shaft universal joint coupling: a common type consisting of a cross shaft and four bearings

2. Ball cage universal joint coupling: using a cage and steel ball structure, the transmission is smoother
   

3. Dual universal joint coupling: Two single universal joint combinations can eliminate speed fluctuations

4. Telescopic universal joint coupling: capable of axial displacement compensation
   

In the application of bending machines, cross axis universal joints are more commonly used due to their strong load-bearing capacity and simple and reliable structure.

The universal joint coupling for the rolling machine has been optimized for the special working conditions of metal sheet rolling

1. Reinforced cross shaft: forged from alloy steel and subjected to special heat treatment process
   

2. Heavy duty bearing unit: equipped with high-precision needle roller bearings and optimized lubrication channel design
   

3. Protective structure: Multi layer sealing design to prevent the invasion of oxide skin and coolant
   

4. Balance processing: High speed products undergo dynamic balance testing
   

5. Temperature adaptation: Operating temperature range -30 ℃ to 120 ℃

The universal joint coupling of the rolling machine, as a key link in power transmission, directly affects the overall operation of the equipment in terms of its performance. Correctly selecting, installing, and maintaining universal joint couplings can not only ensure the stable operation of the rolling machine, but also significantly extend the service life of the equipment.
