The electric motor rotating shaft is horizontal, the drive pinion spin axis is also horizontal. The issue is 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 way of rotation.
Trusted in industry, cardan shafts have confirmed practical on applications where space is limited-as well as in situations where an factor in the machine train (e.g. paper roll) might need to end up being actuated (Cardan Shaft china dynamically positioned) to another position when the devices are not jogging. The universal joint permits limited activity without uncoupling. To make sure sufficient lubrication circulation, which helps prevent the universal joints from seizing, cardan shafts are usually installed with an position from 4 to 6 6 degrees at the universal joints. Experience, though, has displayed that the angle between the shafts of the driver and influenced unit should be kept to a minimum, preferably less than 4.36 mrads (0.25 degrees). Ideally, the angles between your driver and motivated shafts and the cardan shaft, shown as β1 and β2 in Fig. 1, will be equal. Geometrically, this might equate to zero angularity existing between your driver and driven unit: Put simply, the shafts of the driver and influenced machine would be parallel to each other.
Usually it consists of a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, amongst others. It can be a element of the transmission system, its function is normally to redirect the engine turning movements, after moving through the gearbox and the travel to the wheel, going 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 a suitable solution according to your specific requirements.
Cardan shaft, also known as cardinal shaft, is a component of torque transmission.
