This mechanism converts the rotation of a central cam into horizontal reciprocation of a large sliding panel. The cam¡¯s offset profile presses alternately against the angled inner surfaces, pushing the green plate from one side to the other while the frame keeps its motion strictly linear.

Components — Red central cam, blue camshaft and bearings, green sliding panel, yellow sliding block, angled guide surfaces, and the surrounding rectangular frame.

How it works — As the red cam rotates, its eccentric surface presses¡ªfirst on one angled wall, then the other¡ªforcing the green panel to shift sideways. Because the panel is confined by linear guides, all the cam¡¯s radial movement is redirected into a clean horizontal translation. The oscillation speed is determined by the cam¡¯s rotation, and the stroke length depends on the cam¡¯s eccentricity and the angle of the guide faces.

Applications — Ventilation louvers, reciprocating screens, automated shutters, motion displays, and mechanisms requiring simple rotational-to-linear conversion across a large surface.

Why it matters — Using a single cam to drive a broad sliding panel creates smooth, low-friction motion with minimal parts. This design is compact, mechanically reliable, and ideal for applications where consistent, rhythmic translation is needed without complex linkages.
