Disk cam mechanisms with a translating follower having symmetrical double rollers

Design of Cam Mechanisms with a Translating Follower Having Symmetrical Rollers

“…The pressure angle the cam can be reduced during the rising and fall motions. Wu et al proposes a translating follower having symmetric rollers and the cam profile was determined by employing the concept of velocity instant center [4]. Hsieh [5][6] utilized a homogeneous coordinate transformation method to derive an analytical expression for the curved slots of the Geneva wheel and slider cam.…”

Deflection Estimation of Un-Symmetric Isotropic Cam with Three Circular-Arc Contact Profiles

“…Moreover the fatigue life and microscopic edge cracks for two open-celled foamed polymers having different densities is measured in compression impact using a cam-driven compound pendulum system and observed that the material measurements at constant incident energy included the static compression modulus and peak dynamic stress, which progressively degraded as the number of impacts approached one million, [4]. On the other hand the optimum displacement curve is found for which cam-follower velocity curve, acceleration curve, dynamic response of jerk, pressure angle, induced force and stress of experimental outputs to be continuous and their peak values as small as possible on both the rising and the falling motion of the cam-follower with changing the control points of degree three and six which used in B-spline polynomial by using advanced techniques for data acquisition and data processing, [5,6,7]. A synthesis method is described for designing flexible cam profile of marine engine with just one revolving scan of the profile and analyzed the minimum zone criterion of the form deviation error of disc cam by using smoothing cubic spline curves interpolation for specifying maximum and minimum distance between two curves, [8,9].…”
