Increased torsional stiffness

Increased torsional stiffness

The Budgetbeam shaft coupling from Abssac delivers a high torsional stiffness and torque transmission capability, that ensures 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 couldn’t be easier. Two distinct options are available. The set screw shaft attachment design, where two sets of grub screws at 120 degrees apart affix to the shaft at each hub end, or 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 to 12mm the Budgetbeam shaft coupling is a low cost, superior way of ensuring torsional wind up does not enter into your drive designs. 


 The low cost connection solution is having great success in closed loop encoder and servomotor applications as well as lead screw to motor connection both of which require high torsional stiffness to avoid loss of registration.
