The engine rotating shaft is horizontal, the drive pinion spin axis can be horizontal. The difficulty is that these axes aren’t aligned, they are Cardan Shaft china 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 about applications where space is limited-as well as in situations where an factor in the device train (e.g. paper roll) may need to become actuated (dynamically positioned) to an alternate position when the equipment are not working. The universal joint permits limited movements without uncoupling. To make sure enough lubrication circulation, which inhibits the universal joints from seizing, cardan shafts are normally installed with an position from four to six 6 degrees at the universal joints. Knowledge, though, has proven 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 might equate to zero angularity existing between your driver and driven product: Put simply, the shafts of the driver and motivated machine would be parallel to each other.
Usually it includes a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, among others. It is definitely a component of the transmission system, its function is certainly 
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 staff will gladly support you in finding the right universal joint for the application or will develop the right solution according to your specific requirements.
Cardan shaft, also called cardinal shaft, is an element of torque transmission.
