The motor rotating shaft is horizontal, the drive pinion spin axis is also horizontal. The trouble is these axes are not aligned, they are parallel to each other. The Cardan Shaft redirects the travel shaft to the travel pinion without changing the direction of rotation.
Widely used in industry, cardan shafts have tested practical in applications where space is limited-as well since in circumstances where an component in the device train (e.g. paper roll) might need to always be actuated (dynamically positioned) to another position when the equipment are not working. The universal joint permits limited activity without uncoupling. To ensure satisfactory lubrication circulation, which avoids the universal joints from seizing, cardan shafts are usually installed with an position from four to six 6 degrees at the universal joints. Experience, though, has proven that the angle between the shafts of the driver and influenced unit ought to be kept to a minimum, preferably significantly less than 4.36 mrads (0.25 degrees). Preferably, the angles between the driver and driven shafts and the cardan shaft, displayed as β1 and β2 in Fig. 1, will be equal. Geometrically, this might mean zero angularity existing between the driver and driven unit: Put simply, the shafts of the driver and driven 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 element of the transmission system, its function is certainly to redirect the engine turning movements, after passing 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 proper universal joint for the application or will develop the right solution according to your unique requirements.
Cardan shaft, also referred to as cardinal shaft, is an element of torque transmission.
