The motor rotating shaft is horizontal, the drive pinion spin axis is also horizontal. The trouble is that these axes aren’t aligned, they will be parallel to one another. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the route of rotation.
Widely used in industry, cardan shafts have confirmed practical about applications where space is limited-as well while in conditions where an component in the machine train (e.g. paper roll) might need to always be actuated (dynamically positioned) to an alternate position when the devices are not jogging. The universal joint allows for limited activity without uncoupling. To ensure adequate lubrication circulation, which in turn helps prevent the universal joints from seizing, cardan shafts are normally installed with an angle from 4 to 6 6 degrees at the universal joints. Encounter, though, has proven that the angle between the shafts of the driver and motivated unit should be kept to a minimum, preferably less than 4.36 mrads (0.25 degrees). Preferably, the angles between the driver and influenced shafts and the cardan shaft, displayed as β1 and β2 in Fig. 1, would be equal. Geometrically, this would mean zero angularity existing between the driver and driven unit: Put simply, the shafts of the driver and influenced machine would be parallel to each other.

Usually it consists of a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, amongst others. It is usually a component of the transmission program, its function is definitely to redirect the engine turning movements, after passing through the gearbox and the drive to the wheel, going right through the ‘planetary and satellite’ system etc.

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