Latest Patents
One of Jie Tan's latest patents is the "Face-gear forging method." This invention discloses a face-gear forging die that can be used to near-net forge face gears. The die is constructed from a blank and is cut to specification using a wire electrical discharge machining (EDM) process. This process is computer-controlled and allows for the creation of various face-gear forging dies by simply changing the input specifications. Additionally, the wire EDM process can directly cut the face gear tooth, bypassing the forging procedure. The complex, curved surfaces of the face gear teeth are mathematically approximated and executed by the wire EDM apparatus.
Another significant patent is the "Face gearing with conical involute pinion." This invention features a unique gear set that includes a conical involute pinion and a mating face gear. The arrangement allows the gears to mesh and transmit high torque at high speeds, which is particularly useful in helicopter transmissions. The pinion teeth are formed as involute helicoids generated from a base cylinder, ensuring efficient performance.
