The pressure angle in involute gears
WebbUsing: ρ = r B 1 + t 2. And noting that the pitch radius is r P = r B / cos ϕ, where ϕ is the pressure angle, then: r B cos ϕ = r B 1 + t P 2. And, by algebraic manipulation, it can be shown that: t P = tan ϕ. Note that ϕ is in radians. Now, θ P can be determined using the second of the polar formulae: θ = t − arctan t.
