Abstract

The subject of this paper is an investigation of the mechanical stress in rotational coaxial magnetic gear, caused by magnetic torque. The magnets, utilized in the construction of the gear, are Alnico, ferrite, Samarium-Cobalt and Neodymium Iron Boron magnets. Their compressive stress value is evaluated and compared with material strength values for all four types of the magnets. The compressive strengths of one magnet's segments of the outer rotor of the magnetic gear are also evaluated. Ansys Maxwell is used for modelling of magnetic torque of the gear under investigation.

永磁体在旋转磁力齿轮中的机械强度
本文研究了磁转矩对同轴旋转磁齿轮的机械应力影响。在齿轮结构中使用的磁体是铝镍钴,铁氧体,钐钴和钕铁硼磁体。评估了它们的压应力值,并将其与所有四种磁体的材料强度值进行了比较。并对磁性齿轮外转子的一块磁体的抗压强度进行了评价。利用Ansys Maxwell对所研究齿轮的磁转矩进行建模。
