MECHANICAL ENGINEERING 130 - Fall 2015
Design of Planar Machinery: Introduction to Mechanisms design and analysis. Graphical and analytical synthesis of mechanisms, path, motion, and function generation mechanisms. Complex polar notation and closed loop vector equations to analyze mechanisms.
Design Intent: Our group wanted create a device that could peel apples loaded onto a revolving tray. The mechanism is powered by a single motor that output shaft is connected to a planetary gear box. A single motor that drives the peeler and tray allows the mechanism to always be timed without the use of a micro-controller. The horizontal gear train operates the intermittent rotation of the tray via a Geneva wheel as well as rotates the apples on skewers. The vertical gear train rotates a spring loaded peeler that is guided along a cam profile.
