摘要

本研究之目的乃針對徑向式磁性聯軸器之量測與分析，內部磁塊為永磁性銣鐵硼N35磁鐵，以不同距離深度的傳輸扭矩，並應用電腦分析軟體進行模擬，在與實驗作比較分析。針對本研究的磁性聯軸器於裝配時所產生的誤差現象，進行其對傳輸扭矩的影響分析，以期許能達到對此磁性聯軸器使用特性上有更深一層的瞭解。磁性聯軸器有保護過負載性質，可以保護精密設備，也無磨耗及損失摩擦阻力，所以震動非常的小也比較安靜。本研究磁性聯軸器之傳輸效率很好，且在磁極間隙相同的條件下，傳輸扭矩愈大，效率愈高。永磁聯軸器是透過磁力將主動軸與被動軸聯接起來的一種新型聯軸器，且無直接的聯接，利用磁力可穿透一些材料物質和空間距離的特性，進行能量的傳送。結果顯示，使用有限元素法進行電腦模擬分析扭矩、磁極間距與滑差角的關係值，跟實驗值的誤差皆約在百分之15以內。

Purpose of research this examine and analyze to the intersection of radial and the intersection of type and magnetic quantity of shaft coupling, internal magnetic piece magnetic the intersection of rubidium and the intersection of iron and magnet of N35 boron, forever, with different from transmission torsion of depth and employ the computer to analyze the software is imitated, doing comparative analysis with the experiment. To error phenomena produced on assembly of magnetic shaft coupling of this research, carry on it to effect analysis which transmits the torsion, in order to expect that can reach to there is understanding one layer deeper on this magnetic shaft coupling application characteristicking. The magnetic shaft coupling has protected load properties, can protect the accurate apparatus, also have no abrading and loss to rub resistance, so it is very small to shake quieter. The transmission efficiency of the magnetic shaft coupling of this research is very good, and under the same condition of interval of magnetic pole, transmit the bigger torsion and the higher efficiency is. The shaft coupling of permanent magnetism is a new kind of shaft couplings linking initiative axle and passive axle through the magnetic force, and without direct connection, can penetrate some material materials and characteristics of the distance of space with the magnetic force, carry on the conveyance of energy. The result reveals, use the limited element law to carry on the simulation of computer and analyze the interval of torsion, magnetic pole and relation value of the slippery difference angle, all less than about 15% with errors of the experiment value.
