The electric motor rotating shaft is horizontal, the travel pinion spin axis is also horizontal. The issue is that these axes are not aligned, they will be parallel to one another. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the direction of rotation.
Widely used in industry, cardan shafts have verified practical on applications where space is limited-as well because in circumstances where an component in the machine train (e.g. paper roll) may need to always be actuated (dynamically positioned) to another position when the devices are not working. The universal joint permits limited motion without uncoupling. To make sure adequate lubrication circulation, which prevents the universal joints from seizing, cardan shafts are usually installed with an angle from 4 to 6 6 degrees at the universal joints. Experience, though, has proven that the angle between your shafts of the driver and powered unit ought to be kept to the very least, preferably significantly less than 4.36 mrads (0.25 degrees). Preferably, the angles between the driver and powered shafts and the cardan shaft, proven as β1 and β2 in Fig. 1, will be equal. Geometrically, this might equate to zero angularity existing between the driver and driven product: Basically, the shafts of the driver and powered machine will be parallel to one another.

Usually it contains a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, among others. It is a component of the transmission system, its function is to redirect the engine turning activity, after moving through the gearbox and the travel to the wheel, going through the ‘planetary and satellite’ system etc.

Our specialised personnel will gladly support you in finding the right universal joint for your application or will develop the right solution according to your specific requirements.
Cardan shaft, also called cardinal shaft, is a component of torque transmission.
