Latest Patents
One of his latest innovations is the elastomer series coupling damper for superchargers. This invention features a coupling assembly arranged between an input shaft and a rotor shaft of a supercharger. It includes a first hub, a second hub, a first side coupling assembly, a second side coupling assembly, a central hub, and a plurality of coupler pins. The first hub is mounted for concurrent rotation with the input shaft, while the second hub is mounted for concurrent rotation with the rotor shaft. The first side coupling assembly incorporates a first side coupling body and a first side elastomeric insert, which contains a first and second plurality of lobes. The design of the pockets in the coupling body is tangentially offset, allowing for effective engagement with the lobes.
Another patent by Pratley also focuses on an elastomer series coupling damper for superchargers. This version includes a coupling assembly with a first hub mounted with the input shaft and a second hub mounted with the rotor shaft. The central hub, positioned between the two, features an elastomeric body that defines a series of inwardly tapering passages. These passages provide incremental dampening against the coupler pins, enhancing the performance of the supercharger.
