Rolling Mills Cardan Shafts Manufacturers

In choosing the right cardan shaft for rolling mills, there are several factors that need to be taken into consideration such as the size of the load, the transmission speed, the installation accuracy of the two connecting parts, the rotational stability and the price. The type of joint is chosen based on the other characteristics of the joints.

How to choose the right cardan shaft?

There are a few factors that need to be kept in mind when choosing the right cardan shaft for rolling mills. These are:

Due to several factors such as temperature change, load deformation, manufacturing and installation, it becomes very difficult to keep shafts in accurate alignment after installation. There will certainly be a shift. A sliding joint is selected in cases where the radial displacement is large. Universal shafts are used to connect two axes with large angular intersection or displacement. Flexible couplings are selected in cases where a large additional relative displacement is produced by the two shafts during the work process.

It is also necessary to take into account the centrifugal force caused by the working speed of the coupling. Couplings with high balancing accuracy should be chosen for high speed drive shafts. These include membrane joints and others. There are others such as eccentric slider joints which should be avoided in these cases.

The nature and extent of the torque to be transmitted and the additional requirements for the vibration damping function are also important factors. For example, if the process requires a heavy-duty transmission with high power, then gear couplings should be selected. Tire couplings should be chosen in cases where a severe shock load needs to be transmitted in order to eliminate torsional vibrations of the shaft system.

Basic steps when selecting Shafts

The cardan shafts of the rolling mills must be chosen according to the following steps:

The nature and size of the torque to be transmitted and the requirements for the damping and buffering function are also necessary to make the right choice. For example, gear couplings are chosen in cases where a transmission for heavy loads is required.

It is also necessary to take into account the direction and extent of the relative displacement between the two axes.

The working environment and the reliability of the cardan shaft of the rolling mills also play an important role. Usually, universal joints made of metal without lubrication are quite reliable. However, the performance of the coupling is affected by the perfection of the lubrication, thus polluting the environment. Joints that contain non-metallic elements such as rubber are highly sensitive to corrosive fluid, light and temperature.

For satisfactory performance, couplings with a convenient disassembly and installation process along with low cost and easy maintenance must be selected. For example rigid couplings are not only simple in structure but are also convenient in installation and disassembly.

Cardan shaft rolling mills are available in different types and varieties. Choose the right one from the cardan shaft manufacturers of the nearest rolling mills for trouble-free installation and operation of your machine.
