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
