(b) Trochoid Interference This refers to an interference occurring at the … Webρ = 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.

WebCalculating the forces on an involute spur gear is easy. Because of the involute tooth design, the worst loading cast is when the gears mesh where the pitch diameters intersect at the tangent point. Since the gears mesh at the pressure angle (14.5°, 20° or 25°). we will have two components to deal with. The tangential force and the radial force.
