TANDEM SCOTCH YOKE ENGINE

Tandem Scotch Yoke Engine, a reciprocating mechanism known for converting linear motion into rotational motion with high geometric efficiency. The model features a vibrant color palette—British racing green, deep red, and polished metallic finishes—giving it the appearance of a high-end educational model or a precision-engineered steam plant component. Mechanism Breakdown The "Tandem" configuration refers to the dual-cylinder setup arranged in a straight line, sharing a common central drive. Dual Cylinders: Located on the left and right, the silver-finished cylinders house the pistons. The outer casings are secured with brass-toned bolts, suggesting a heavy-duty, pressurized design. The Scotch Yoke: In the center, the two piston rods connect to a sliding yoke. Unlike a traditional connecting rod/crankshaft setup, this yoke translates the linear movement of the pistons directly into a circular path via a sliding block. Central Flywheel: A large, red-spoked flywheel is mounted behind the yoke. This provides the necessary inertia to smooth out the power strokes and maintain constant rotational speed. Base and Support: The entire assembly is mounted on a solid, brushed-aluminum baseplate. The green supports (pillow blocks) hold the precision-ground guide rods and the main crankshaft in place.
