Cardan Shaft Of Rolling Mill

The cardan shaft of the rolling mill is a key transmission component that connects the main transmission device of the rolling mill with the rolling mill rolls. It can transmit torque and rotational motion even when the two axis lines are relatively offset. This special mechanical device consists of core components such as a cross shaft, fork head, and bearing sleeve, and achieves multi angle power transmission through its unique structural design.

Working principle: When the driving shaft rotates, the rotational motion is transmitted to the driven shaft through the hinge action of the cross shaft, and even in the case of a certain angle between the two shafts, smooth power transmission can still be maintained. This characteristic is particularly important in the steel rolling production process, as the position of the rolling mill will change during the adjustment of the pressure.

Special application requirements in steel rolling production

1. Adaptation to hot rolling conditions:
   Must withstand environmental temperatures up to 200-300 ℃ in the rolling zone
   Specially designed insulation cover to prevent thermal radiation from affecting lubrication
   Cooling air ducts are installed at the bearing parts

2. Overload impact characteristics:
   The design safety factor is usually taken as 3-5 times
   Finite element analysis is used to optimize stress distribution
   Overload protection structures are set up in key areas
   

3. Quick replacement design:
   modular structure facilitates online replacement
   hydraulic quick disassembly device
   centering adjustment mechanism simplifies installation process

With the development of high-speed and precision steel rolling technology, universal coupling as key transmission components, have a direct impact on the operational efficiency and product quality of the entire production line due to their technical level and reliability. Modern rolling mill universal shafts are continuously innovating towards longer lifespan, higher reliability, and more intelligent monitoring, providing important support for the intelligent transformation and upgrading of the steel industry.
