The engine rotating shaft is horizontal, the drive pinion spin axis is also horizontal. The difficulty is these axes are not aligned, they will be parallel to one another. The Cardan Shaft redirects the drive shaft to the travel pinion without changing the path of rotation.
Trusted in industry, cardan shafts have proven practical about applications where space is limited-as well as in circumstances where an element in the device train (e.g. paper roll) may need to end up being actuated (dynamically positioned) to an alternate position when the devices are not working. The universal joint permits limited activity without uncoupling. To ensure enough lubrication circulation, which stops the universal joints from seizing, cardan shafts are usually installed with an angle from 4 to 6 6 degrees at the universal joints. Knowledge, though, has proven that the angle between the shafts of the driver and influenced unit ought to be kept to the very least, preferably less than 4.36 mrads (0.25 degrees). Ideally, the angles between the driver and powered shafts and the cardan shaft, demonstrated as β1 and β2 in Fig. 1, would be equal. Geometrically, this would equate to zero angularity existing between your driver and driven unit: In other words, the shafts of the driver and powered machine would be parallel to each other.

Usually it includes a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, amongst others. It can be a component of the transmission system, its function is normally to 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 staff will gladly help you find the right universal joint for your application or will develop the right solution according to your unique requirements.
Cardan shaft, often known as cardinal shaft, is an element of torque transmission.
