This assembly is then inserted into a hub. A keyed shaft has a small recess where a key is placed in. We are probably all familiar with keyed shafts because this type is predominant in the industry. Shafts come in two varieties: Keyed and splined. However, there are three options to get great alignment with a pump or motor. This is not ideal and will definitely wear out the spider coupler faster. Each loading of the jib changes the alignment if only for a few seconds. Even if we get all of these things perfectly aligned, which didn’t happen, if the jib is loaded to this side, the stiffness of the frame causes these to shift.Washers were used to shim and they have discrete shimming heights which limits adjustment.
As temperature and humidity change, so will the height and angle of the engine. The motor is mounted on a piece of wood.The pump (left) is mounted on a thin piece of flat steel and cannot be adjusted for angularity.The example here, a log splitter, is almost exactly how not to do this. It can mean the difference between a long-lasting system and one that constantly needs maintenance. The product has a keen market price, fast delivery and ISO9001 assurance to give the product a competitive edge.Keeping your pump and motors on the same center and parallel is critical and often difficult to do. The splined shafts can also be complimented by a range of matched phosphor bronze flange nuts’ which are supplied complete with PCD arranged attachment holes. Standard lengths of 250,500,1000,20mm are available from stock. A full range of flanged steel or bronze sleeves are available to compliment the splines. Abssac was successful in being able to replicate the part and deliver the new part ready to fit into the repaired machine.Īs standard splined shaft are available from 14mm to 54mm in diameter with either 6 or 8 spline formats. The only information available was to be gathered from the broken and distorted sample sent to us after a catastrophic failure at the paper mill. Manufactured from EN24T steel the customer did not have any technical drawings from which we could quote from.
Measuring a massive 150mm in diameter, with 8 splines along its 2 metres length and weighing in at 250kg !. Machined from high grade EN8 steel in diameters of 14mm to 54mm as standard and supplied in lengths up to 3 metres enables us to supply into the most high load and long life expectancy linear applications.Ībssac has recently supplied one of the largest splined shafts to date.
