The electric motor rotating shaft is horizontal, the drive pinion spin axis can be horizontal. The problem is that these axes are not aligned, they will be parallel to one another. The Cardan Shaft redirects the travel shaft to the drive pinion without changing the direction of rotation.
Widely used in industry, cardan shafts have tested practical upon applications where space is limited-as well when in circumstances where an factor in the machine train (e.g. paper roll) may need to end up being actuated (dynamically positioned) to an alternate position when the equipment are not jogging. The universal joint permits limited activity without uncoupling. To make sure satisfactory lubrication circulation, which inhibits the universal joints from seizing, cardan shafts are normally installed with an position from 4 to 6 6 degrees at the universal joints. Knowledge, though, has displayed that the position between your shafts of the driver and driven unit ought to be kept to a minimum, preferably less than 4.36 mrads (0.25 degrees). Preferably, the angles between your driver and driven shafts and the cardan shaft, displayed as β1 and β2 in Fig. 1, will be equal. Geometrically, this would equate to zero angularity existing between your driver and driven product: Put simply, the shafts of the driver and Cardan Shaft china 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 can be a component of the transmission system, its function is normally to redirect the engine turning motion, after moving through the gearbox and the drive 
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 the right solution according to your specific requirements.
Cardan shaft, also referred to as cardinal shaft, is an element of torque transmission.
