The engine rotating shaft is horizontal, the travel pinion spin axis is also horizontal. The trouble is these axes aren’t aligned, they will be parallel to each other. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the direction of rotation.
Trusted in industry, cardan shafts have proven practical about applications where space is limited-as well seeing that in conditions where an factor in the machine train (e.g. paper roll) might need to end up being actuated 
(dynamically positioned) to an alternate position when the machines are not working. The universal joint permits limited movement without uncoupling. To ensure sufficient lubrication circulation, which inhibits the universal joints from seizing, cardan shafts are usually installed with an position from four to six 6 degrees at the universal joints. Encounter, though, has proven that the position between the shafts of the driver and motivated unit ought to be kept to the very least, preferably significantly less than 4.36 mrads (0.25 degrees). Preferably, the angles between your driver and driven shafts and the cardan shaft, proven as β1 and β2 in Fig. 1, would be equal. Geometrically, this would mean zero angularity existing between your driver and driven product: Basically, the shafts of the driver and motivated machine will 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 normally a component of the transmission program, its function is to redirect the engine turning motion, after passing through the gearbox and the drive to the wheel, going through the ‘planetary and satellite’ system etc.
Our specialised staff will gladly help you find the proper universal joint for your application or will develop a suitable solution according to your unique requirements.
Cardan shaft, also referred to as cardinal shaft, is a component of torque transmission.
