Since In~l = In2[ = 1, by substituting equations (21)-(24) into equation (20) the following five
independent equations can be obtained:
B1 cos(tkl - ~kt ) - Al sin(t~l -- ~1 ) -- x2 cos ~b2 - Y2 sin ~b2 + Sw = 0, (25)
Btsin(cbl-tPl)+AlCOS($l-~l/l)+[x2sin~b2-y2cosck2]cosTw+z2sin~,w=O, (26)
CI - P1 ~1 + [x2 sin ~b 2 - Y2 cos t~2]sin 7w - z2 cos Yw = 0, (27)
nl ..2 _1 ..2 = 0 (28) ),wtlzw -- tlz,,vttyw
and
1 2 l 2 n~n~w -- n~wnxw = 0. (29)
The above system equations contain seven unknowns 01, 0o, ~k~, ~ko, qg~, ~b 2 and ~b h. We may
consider the worm rotation angle ~bl as an input, and other size unknowns can thus be determined.
By solving the system equations (25)-(29) and the equation of meshing (18) simultaneously,
coordinates of every instantaneous contact point can be obtained.

因为 ln-=ln2=1,把公式（21）-（24）代入到公式（20），就可以得到下列五个独立的方程（25），（26），（27），（28）和（29)。
上述方程组包含七个未知数，01,0o,-k,-ko,qg,-b2 和 bh.我们考虑把蜗杆（论）的转角作为输入，则可决定其它未知的尺寸。
解方程组（25）-（29），并与啮合方程（18）进行联立，就可获得每一瞬间接触点的坐标。（译注：这是计算蜗轮，蜗杆啮合情况的一段话）
