Parametrische Zahnstange mit Ritzel / Parametric Gear Rack and Pinion

thingiverse

Parametric Gear Rack and Pinion Creates a gear rack and pinion. Helical gears run more smoothly than gears with straight teeth. However, they also create axial loads which the bearings must be designed to contain. Recommendations for the helix angle depending on the module can be found in DIN 3978. With a given module m and zp teeth on the pinion, the distance between the pinion's axis and the rack's pitch line is m/2·zp This script adjusts the pressure angle in the transverse section to the helix angle: e.g. with a 20° helix angle, a pressure angle of 20° becomes a pressure angle of 21.17° in the transverse section. Format: zahnstange(modul, laenge_stange, hoehe_stange, breite, eingriffswinkel=20, schraegungswinkel=0) Parameters: modul = height of the tooth above the pitch line laenge_stange = length of the rack hoehe_stange = height from bottom to the pitch line zahnzahl_ritzel = number of teeth on the pinion bohrung_ritzel = central bore diameter of the pinion breite = face width eingriffswinkel = pressure angle, standard value = 20° according to DIN 867 schraegungswinkel = bevel angle perpendicular to the rack's length resp. helix angle to the rotation axis on the pinion; 0° = straight teeth zusammen_gebaut = assembled (1) or disassembled for printing (0)
