On the Determination of Basic Dimensions of a Cam With a Translating Roller-Follower

Abstract

The problem of determination of basic dimensions from the point of view of follower jamming of a cam with translating roller-follower is addressed. Departing from the common practice of using only a constant pressure angle to assess jamming of the follower in its guide, this paper presents a detailed analysis of the problem taking into consideration the follower-guide friction. This leads to new bounds on the pressure angle. Based on the bounds obtained, a graphical method for determination of the optimal values of the basic dimensions is proposed. A numerical example is presented for the purpose of illustration.
