Latest Patents

Hasuda's latest patents include a method of manufacturing a disk for a variator and a belt-type non-stage transmission system. In the first patent, he describes a method of fabricating a variator disc, where the outer periphery of the input disc is finished using the input shaft as a working reference. This method ensures high precision in the finishing process. The alternative method involves forming a spline hole with a machining allowance, which is then precisely finished after the heat treatment of a blank.

The second patent focuses on a belt-type continuously variable speed system. In this system, a hydraulic cylinder operates in conjunction with an elastic member in a tensioner to draw a belt against another elastic member contained in a variable radius pulley. This mechanism allows for the power transmission ring to be displaced, achieving speed variation through a balance of forces.
