The engine rotating shaft is horizontal, the travel pinion spin axis is also horizontal. The trouble is that these axes aren’t aligned, they are parallel to each other. The Cardan Shaft redirects the drive shaft to the drive pinion without changing the route of rotation.
Widely used in industry, cardan shafts have proven practical about applications where space is limited-as well because in scenarios where an aspect in the device train (e.g. paper roll) might need to be actuated (dynamically positioned) to an alternate position when the devices are not working. The universal joint permits limited movement without uncoupling. To make sure enough lubrication circulation, which helps prevent 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 demonstrated that the angle between the shafts of the driver and powered unit should be kept to a minimum, preferably significantly less than 4.36 mrads (0.25 degrees). Ideally, the angles between your driver and driven shafts and the cardan shaft, displayed as β1 and β2 in Fig. 1, would be equal. Geometrically, this would equate to zero angularity existing between the driver and driven device: In other words, the shafts of the driver and influenced 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 is usually a component of the transmission program, its function is to Cardan Shaft china redirect the engine turning motion, after passing through the gearbox and the travel to the wheel, going 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 a suitable solution according to your specific requirements.
Cardan shaft, often known as cardinal shaft, is an element of torque transmission.
