# No. 43, Different kinds of gears for transmitting rotary motion from one shaft to another arranged
# obliquely thereto (Brown 1868; plate 42-43).
#
# Model (cm): skew gears (oblique teeth) for two shafts crossing at right angles without meeting,
# the second form of the plate after No. 42's bevels. A 12-tooth gear on a horizontal shaft running
# front to back drives a 24-tooth gear on a shaft running left to right above it, 12.73 higher. Both
# have their teeth oblique at 45 deg, the same hand, so where the two touch their tooth lines lie
# together; normal module 0.5, so the pitch radii are 4.24 and 8.49 (batch7/gen043.py). Each tooth
# is ten short straight-flanked segments twisting along the face, each the convex hull of its end
# sections. The gears touch at a point that the teeth sweep across; the speed ratio goes by the
# tooth counts, 12/24, whatever the radii. Only the 12-tooth shaft is motor-driven.
