The motor rotating shaft is horizontal, the drive pinion spin axis can be horizontal. The difficulty is that these axes are not aligned, they are parallel to one another. The Cardan Shaft redirects the drive shaft to the travel pinion without changing the way of rotation.
Trusted in industry, cardan shafts have proven practical in applications where space is limited-as well since in situations where an factor in the machine train (e.g. paper roll) may need to be actuated (dynamically positioned) to an alternate position when the equipment are not jogging. The universal joint allows for limited movements without uncoupling. To make sure adequate lubrication circulation, which helps prevent 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 shown that the position between the shafts of the driver and powered unit ought to be kept to a minimum, preferably significantly less than 4.36 mrads (0.25 degrees). Preferably, the angles between your driver and influenced shafts and the cardan shaft, shown as β1 and β2 in Fig. 1, would be equal. Geometrically, this might mean zero angularity existing between your driver and driven unit: Basically, the shafts of the driver and powered machine will be parallel to each other.

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

Our specialised staff will gladly help you find the proper universal joint for the application or will develop a suitable solution according to your specific requirements.
Cardan shaft, also known as cardinal shaft, is a component of torque transmission.
