This paper presents an analytical approach for designing disk cam mechanisms with an improved translating follower having symmetrical double-concave faces. The double-concave faces of such a follower can increase the actual contact area between the cam and the follower. Additionally, during the dwell periods of the follower motion, both the concave faces of the follower can simultaneously contact the cam profile so as to share the carried loading. Such beneficial characteristics can result in a lower level of contact stress between the cam and the follower. Numerical examples are provided to illustrate the nature and the advantage of this improved follower.
