Frictionless gears as an alternative for the traditional gears

Abstract: Omówiono zjawisko tarcia występujące w przekładniach mechanicznych. Podjęto próby opracowania konstrukcji przekładni minimalizujących negatywne skutki tarcia. Zaprezentowano autorskie konstrukcje przekładni beztarciowych objęte zgłoszeniami patentowymi. SŁOWA KLUCZOWE: tarcie, przekładnie mechaniczne, przekładnie toczne, przekładnie magnetyczneThe article discusses the gears and the impact of the friction on the transmission. Then there is the attempt to find the constructions of frictionless gears. Finally th… Show more

“…The undeniable advantages of mechanical gears are high torque density, efficiency, and ease of manufacture. However, their inherent disadvantages include high noise and vibration levels [1][2][3], friction between teeth [4], as well as a substantial maintenance cost. The use of magnetic forces for the transmission of mechanical power instead of physical contact removes at least some of the unwanted features of mechanical gears.…”

“…The contactless transmission of torque by means of magnetic field provides physical isolation between the driver and the driven gear wheels [3,4]. As a result MG can be characterized by increased durability as well as reduction of vibration [5,6] and noise level [7]. Magnetic gears provide also the "natural" protection against overload [8,9].…”
