- Description:
- Application: Pump. This is a variation of the Pappenheim chamber-wheel train, having only one tooth per pump wheel. It was patented as early as 1830 by Lecocq in France, but was built to a large extent by the Hamburg firm of Repsold. The profiles of the teeth beyond the pitch circles and beneath the "points" are epicycloids; the profiles from the pitch circle to the root are essentially hypocycloidal. Delivery of the pump is not uniform, but the variation is so little as to be negligible. Because sliding contact necessarily occurs, it is difficult to maintain a tight joint and therefore the device is suited only to low pressure differentials. The device is built by Repsold's was used in mine draining operations, and as a fire pump-in England it served as a hydraulic motor and as a gas pump in gas works. [Francis Moon 2001-00-00]
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:
