Oscillating Drive via Angled Rotating Plate

Oscillating Drive via Angled Rotating Plate

Mechanisms that convert continuous rotary input into reciprocating linear or swinging output are foundational to machinery ranging from sewing machines to shaper tools. This project analyzes and constructs an inclined disc mechanism, wherein a circular plate mounted at an oblique angle to the drive shaft imparts sinusoidal motion to a follower through a spherical joint or sliding contact. Kinematic modeling derives the displacement, velocity, and acceleration equations as functions of disc inclination angle and rotational speed. A parametric study explores how varying the tilt angle affects stroke length and transmission angle efficiency. The physical prototype is instrumented with encoders and load cells to verify theoretical force transmission ratios and identify regimes of contact separation or excessive wear.
