Generic Settings class

generate_spokes(root_radius, spoke_width, spokes, mount_radius, mount_hole, unit_factor, unit_label)

given a set of constraints - generate the svg path for the gear spokes - lies between mount_radius (inner hole) and root_radius (bottom of the teeth) - spoke width also defines the spacing at the root_radius - mount_radius is adjusted so that spokes fit if there is room - if no room (collision) then spokes not drawn

boxes.gears.gear_calculations(num_teeth, circular_pitch, pressure_angle, clearance=0, ring_gear=False, profile_shift=0.0)

Put base calcs for spur/ring gears in one place. - negative profile shifting helps against undercut.

boxes.gears.generate_rack_points(tooth_count, pitch, addendum, pressure_angle, base_height, tab_length, clearance=0, draw_guides=False)

Return path (suitable for svg) of the Rack gear. - rack gear uses straight sides

• involute on a circle of infinite radius is a simple linear ramp

• the meshing circle touches at y = 0,

• the highest elevation of the teeth is at y = +addendum

• the lowest elevation of the teeth is at y = -addendum-clearance

• the base_height extends downwards from the lowest elevation.

• we generate this middle tooth exactly centered on the y=0 line. (one extra tooth on the right hand side, if number of teeth is even)

boxes.gears.generate_spur_points(teeth, base_radius, pitch_radius, outer_radius, root_radius, accuracy_involute, accuracy_circular)

given a set of core gear params - generate the svg path for the gear

boxes.gears.have_undercut(teeth, pitch_angle=20.0, k=1.0)

returns true if the specified number of teeth would cause an undercut.

boxes.gears.inkbool(val)

boxes.gears.involute_intersect_angle(Rb, R)

boxes.gears.linspace(a, b, n)

return list of linear interp of a to b in n steps - if a and b are ints - you’ll get an int result. - n must be an integer

boxes.gears.point_on_circle(radius, angle)

return xy coord of the point at distance radius from origin at angle

boxes.gears.undercut_max_k(teeth, pitch_angle=20.0)

computes the maximum k value for a given teeth count and pitch_angle so that no undercut occurs.

boxes.gears.undercut_min_angle(teeth, k=1.0)

computes the minimum pitch angle, to that the given teeth count (and profile shift) cause no undercut.

boxes.gears.undercut_min_teeth(pitch_angle, k=1.0)

computes the minimum tooth count for a spur gear so that no undercut with the given pitch_angle (in deg) and an addendum = k * metric_module, where 0 < k < 1

Note: The return value should be rounded upwards for perfect safety. E.g. min_teeth = int(math.ceil(undercut_min_teeth(20.0))) # 18, not 17

rectangularWall(x, y, edges='eeee', ignore_widths=[], holesMargin=None, holesSettings=None, bedBolts=None, bedBoltSettings=None, callback=None, move=None, label='')

The callback is called for each edge in counter-clockwise order with the current position at the start of the edge. The position is independent of the width of the edge (positive y move to the “inside” of the wall, negative y move over the edge).

ignore_widths extends adjacent edges to cover for the width. The diagram below shows where edges are extended for each number. Note that for edges from two parts to still match this needs to be done on both sides and both parts need to use same edge or at least an edge with the same width.
