Links 1 and 2 are connected by turning pairs A and B to the base, and their turning axes are perpendicular and intersect. Links 1 and 2 contact each other through edges d-d and f-f of triangular prisms m and n. Edge f-f of link 2 intersects its turning axis at the arbitrarily given angle ψ. Edge d-d of link 1 is perpendicular to and intersects its turning axis. Angle ϕ₁ of rotation of link 1 is related to angle ϕ₂ of rotation of link 2 by the equation ϕ₁=arctan((b tan(ϕ₂))/(a+(b/(cos(ϕ₂))cot(ψ))).
