Development of End Effector by Noncontact Power Transmission Device

在本研究中，我们开发了一种利用磁力齿轮的非接触式动力传动装置。磁齿轮的齿距变化会影响磁感应强度。为了避免小直径钻头折断，采用了磁力齿轮扭矩限制器。小直径钻头在切削加工过程中，由于切削屑的影响，钻头经常发生断裂。但是，我们避免了折断小直径钻头。此外，我们在不同的条件下应用该装置。因此，我们在难以切割的条件下进行微细加工。

In this research, we developed the machine that is noncontact power transmission device by using magnetic gear. The magnetic flux density is changed with the distance of magnetic gear. In order to avoid breaking the small diameter drill, we applied torque limiter used in the magnetic gear. The small diameter drill is frequently broken according to the effect of machining swarf. However, we avoided breaking the small diameter drill. Moreover, we applied the device under different conditions. As a result, we machine microfabrication under conditions difficult to cutting work.
