Latest Patents

One of Yamada's latest patents is for an automobile transmission casing that features a unique reinforcement design. This casing includes a peripheral wall with an inner surface composed of a cross-section of multiple curved portions, which are interconnected through inwardly projecting node portions. This innovative configuration provides a structure of high rigidity, effectively suppressing vibrations of the casing wall and reducing noise caused by such vibrations. Additionally, the casing wall is equipped with brackets that support the reverse idle gear shaft near one of the node portions, further enhancing vibration suppression.

Another significant patent by Yamada involves oil seal means for rotary piston engines. In this design, the side housing of a rotary piston engine undergoes a soft-nitriding treatment to create a layer of Fe-C-N type compounds, followed by grinding to achieve a surface roughness between 0.3 and 15 microns. The oil seal, which engages the inner surface of the side housing, features a sealing lip made of chromium plating. This arrangement significantly improves the wear resistance of the oil seal, contributing to the longevity and efficiency of rotary piston engines.
