Product Design HPLA with Toothed Belt Drive (1) The profile The extruded aluminum profile is optimized for highest stiffness (torsion and deflection) at the lowest possible mass by means of the FEM method. The modular concept permits to use the same profile for all HPLA versions: • Drive version with toothed belt • Guiding with plastic rollers on anodized aluminum (2) The carriage The aluminum carriage profile was also optimized by means of the FEM method. The rolling-contact plastic rollers with lifetime lubrication are aligned backlashfree in all directions via eccentric. The carriage is...

Load Bearing Capacity of Toothed Belt and Carriage Operating force Fx transmitted by the toothed belt / pretension The operating force Fx transmitted by the toothed belt depends on its pretension. If not stated otherwise, the HPLA is furnished with a default pretension. With this default pretension, the HPLA can maximally transmit the thrust force F_nominal. If a higher thrust force is required, the toothed belt pretension is increased and forces up to F_max can be transmitted. If the operating force Fx is higher than the belt pretension, toothed belt spread might be the result. Life The...

Definition of Stroke, Usable Stroke and Safety Travel • Usable stroke: The usable stroke is the distance which you need to move in your application. It is always shorter than the stroke. • Stroke: The stroke to be indicated in the order code is the maximum possible stroke between the internal end stops. It is composed of Stroke = Usable stroke + right safety travel + left safety travel + 20 mm*1 1* We recommend to include an extra travel of approx. 10 mm on each side in order to compensate the switching hysteresis of the limit switches or - depending on the controller - as an addition to...
