Cardan Shaft Of Rolling Machine

As the core transmission component of metal sheet forming equipment, the universal shaft of the rolling machine directly affects the rolling accuracy and equipment reliability.

The cardan shaft of the rolling machine adopts a heavy-duty transmission design:

1. Cross axis component: forged from 42CrMo alloy steel, with a surface carburizing and quenching hardness of HRC58-62, and ultra precision grinding of the bearing position

2. Expansion spline: modulus 8-12mm, hardness HRC50-55, axial compensation ± 50-100mm
   

3. Flange connection: standard flange interface, pre tightened with 8.8 grade high-strength bolts
   

4. Balance system: hydraulic counterweight device, balance torque error ≤ 3%

Power transmission characteristics of cardan shaft in plate rolling machine

1. Transmitting the torque of the main motor to the work roll through a cross axis articulated structure
   

2. Axial displacement caused by compensating roller gap adjustment of spline pair
   

3. Drum shaped tooth surface design increases the contact area by 40% and reduces contact stress by 35%

Advantages of universal shaft in plate rolling machine

1. Heavy load capacity: Special alloy material increases torque density by 25%
   

2. Precision compensation: Drum shaped tooth design allows for compensation of 1.5 ° angular deviation
   

3. Intelligent monitoring: optional vibration and temperature sensors (accuracy ± 0.5%)
   

4. Easy maintenance: Split bearing design reduces replacement time by 60%
