- This model is one example of a slider-crank mechanism. The slider crank mechanism is used in internal combustion engines. In this model however, the sliding link or 'piston' is grounded. The slider crank is often used to convert rotary motion into alternating linear motion. Four different inversions of this mechanism are possible by grounding each of the four links. The slider crank mechanism can be found in the drawings of Leonardo Da Vinci. In one device he couples two machine mechanisms, the endless screw or worm drive (Reuleaux model C-9) coupled to a slider-crank. The slider crank mechanism can be seen in a cutaway of a 1950's Chevrolet 'V' block engine; two slider crank mechanisms in the form of pistons, connecting rods and cranks. The application to perhaps a billion internal combustion engines makes the slider-crank mechanism one of the most ubiquitous mechanisms in the world today. The slider crank mechanism is found in every internal combustion engine with cylinder, piston rod and crankshaft. The slider crank mechanism may be the most ubiquitous mechanism in the world, with perhaps a billion of them in existence. In this model the sliding link envelopes the fixed link, whereas in model C4, the slider moves in a slot in the fixed link. [Francis Moon 2003-05-29]
The 220 models in Cornell University’s Reuleaux Collection were built in the late 19th century to demonstrate the elements of machine motion, as theorized by the German engineer Franz Reuleaux. The University acquired the models in 1882 for use in teaching and research. The Reuleaux models are classified according to the alphanumeric schema employed in the catalog of the manufacturer, Gustav Voigt. The letter in a model's ID (e.g., B14 or S35) refers to a class of mechanism; the number is a specific instance of the class. This classification scheme is a simplified version of the taxonomy of machine elements elaborated in Reuleaux's work. - Repository:
