The motor rotating shaft is horizontal, the drive pinion spin axis is also horizontal. The problem is these axes are not aligned, they happen to be parallel to each other. The Cardan Shaft china cardan Shaft redirects the drive shaft to the drive pinion without changing the way of rotation.
Widely used in industry, cardan shafts have proven practical upon applications where space is limited-as well while in circumstances where an component in the machine train (e.g. paper roll) might need to become actuated (dynamically positioned) to another position when the machines are not operating. The universal joint permits limited motion without uncoupling. To make sure sufficient lubrication circulation, which helps prevent the universal joints from seizing, cardan shafts are normally installed with an angle from four to six 6 degrees at the universal joints. Encounter, though, has displayed that the angle between your shafts of the driver and influenced unit ought to be kept to a minimum, preferably less than 4.36 mrads (0.25 degrees). Ideally, 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 would mean zero angularity existing between your driver and driven device: Put simply, the shafts of the driver and driven machine will be parallel to one another.
Usually it includes a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, 
among others. It is usually a component of the transmission program, its function is normally to redirect the engine turning movement, after moving through the gearbox and the travel to the wheel, going right through the ‘planetary and satellite’ system etc.
Our specialised personnel 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 an element of torque transmission.
