The motor rotating shaft is horizontal, the travel pinion spin axis can be horizontal. The trouble is that these axes aren’t aligned, they happen to be parallel to one another. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the route of rotation.
Widely used in industry, cardan shafts have confirmed practical in applications where space is limited-as well when in situations where an factor in the machine train (e.g. paper roll) might need to be actuated (dynamically positioned) to another position when the machines are not working. The universal joint permits limited movements without uncoupling. To ensure satisfactory lubrication circulation, which in turn avoids the universal joints from seizing, cardan shafts are normally installed with an angle from 4 to 6 6 degrees at the universal joints. Experience, though, has proven that the position between the shafts of the driver and driven unit should be kept to the very least, preferably significantly less than 4.36 mrads (0.25 degrees). Ideally, the angles between the driver and influenced 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 your driver and driven product: Basically, the shafts of the driver and influenced machine will be parallel to one another.
Usually it involves a tubular shaft, two sets of Universal Joints and glove system – ferrule stepper, among others. It is normally a element of the transmission system, its function is to redirect the engine turning movement, after moving through the gearbox and the drive 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 your 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.
