Abssac's Budgetbeam shaft couplings deliver a high torsional stiffness and torque transmission capability, along with extremely long life. Using a patented method of manufacture, a high pitch double start helical beam configuration is used within the single piece construction to ensure maximum torsional rigidity whilst offering lower radial loads associated with triple start alternatives.
Attaching the shaft coupling to the motor shaft and driven shaft is simple, with two distinct options available. The first is the set screw shaft attachment design, where two sets of grub screws at 120 degrees apart affix to the shaft at each hub end; and the second is the unique integral clamp attachment design, which ensures shaft concentricity and total shaft clamping for zero backlash, torque delivery.
Available in aluminium or stainless steel as standard, the Budgetbeam shaft coupling can accept up to 5 degrees of angular and 0.1mm of parallel shaft misalignment. Stocked in metric bores from 4mm, 5mm, 6mm, 7mm, 8mm, 10mm and 12mm, the Budgetbeam shaftcoupling is a cost-effective way of ensuring that torsional wind-up does not enter into any drive designs.
