The electric motor rotating shaft is horizontal, the travel pinion spin axis can be horizontal. The issue is these axes are not aligned, they happen to be parallel to each other. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the route of rotation.
Trusted in industry, cardan shafts have proven practical about applications where space is limited-as well because in situations where an factor in the device train (e.g. paper roll) may need to always be actuated (dynamically positioned) to another position when the equipment are not running. The universal joint permits limited activity without uncoupling. To make sure adequate lubrication circulation, which helps prevent the universal Cardan Shaft china joints from seizing, cardan shafts are usually installed with an position from 4 to 6 6 degrees at the universal joints. Knowledge, though, has proven that the position 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 influenced shafts and the cardan shaft, demonstrated as β1 and β2 in Fig. 1, would be equal. Geometrically, this would mean zero angularity existing between your driver and driven product: Quite simply, the shafts of the driver and powered machine will be parallel to one another.
Usually it involves 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 usually to redirect the engine turning movement, after moving through the gearbox and the travel to the wheel, going right through the ‘planetary and satellite’ system etc.
Our specialised staff will gladly help you find the right universal joint for the application or will develop the right solution according to your specific requirements.
Cardan shaft, also referred to as cardinal shaft, is a component of torque transmission.
