dc.description.abstract | 氣動鑽具系統具有高速、低耗能、低發熱量等優點,並廣泛應用於工具機、牙醫器械等領域中,為了深入探討其性能以及促進其發展,本論文目標在於研究開發精密動力量測系統。
根據針對牙醫手機動力量測系統的研究評估,本論文提出非接觸磁性負載原理來開發牙醫手機的動力量測系統。透過位移控制來平順地改變磁性負載,以取代多干擾的摩擦負載方式。除了可變動負載裝置外,動力量測系統還需要有待測牙科手機的夾持單元,以及動力量測感測器和控制單元。 作為動力量測性能的驗證,台灣微動股份有限公司之雙動力微小氣渦輪牙科手機被選為測試樣品。非接觸磁性負載裝置可以對高速旋轉筒匣施予穩定平順的剎車力,得以量測筒匣在不同供氣壓力、軸向與徑向負荷下的動力性能。實驗結果得知,氣渦輪牙科手機輸出的最大功率發生在空負載轉速的80%~90%之間,且約在空負載轉速的70%時有最大轉換率。 | zh_TW |
dc.description.abstract | Because of advantages such as high-speed operation, low energy consumption and low heat emission, pneumatic drilling systems are widely used in the fields of machining tools and dental equipments. In order to comprehend its performance and to enhance its further development, the goal of this thesis is to develop an precision power measurement system.
According to our surveying evaluation of the current power measurement methods for dental handpieces, this thesis proposes using non-contact magnetic loading principle to develop a novel power measurement system for dental handpiece. Through displacement control, the magnetic loading can be smoothly varied to replace the easily interfered frictional loading principle. Besides the loading units, the power measurement system is comprised of the holder for dental handpiece, sensors for power measurement and control unit. For performance verification of our developed power measurement system, the dental handpiece with the twin-powered micro turbine of MicroP Technology (Taiwan) Inc. is chosen as the testing specimen. The non-contact magnetic loading unit can successfully provide smooth and stable braking force for the high-speed rotating cartridge, so that the power performance of cartridge under different air supplies, axial and radial loadings can be measured. The experimental results show that, the maximum power occurs in the range of the 80 to 90 percent of the free running speed, and the maximum energy transformation efficiency appears at 70 percent of the free running speed. | en |
