Latest Patents
Yonghong Chen's latest patents include two groundbreaking inventions. The first is an "External meshing cylindrical gear pair with constant meshing characteristics constructed tooth pair." This invention features a cylindrical gear I and a cylindrical gear II, both designed with constructed tooth pairs based on conjugate curves. The design allows for continuous combined curves that facilitate machining with the same cutter, ensuring a common normal at inflection or tangent points passes through the pitch point of the gear pair. The contact ratio is designed as an integer, enhancing the gear's performance.
The second patent is a "Herringbone planetary gear transmission device with constant meshing characteristics constructed tooth pair." This device includes a sun gear, a planetary gear, and an internal gear, all featuring constructed tooth pairs based on conjugate curves. Similar to his first patent, the normal tooth profiles are designed to be the same combined curve, allowing for efficient machining. The sliding ratio of the meshing gear pair can be adjusted based on the position of the inflection or tangent point, with the contact ratio also designed as an integer.
