磁気かさ歯車の可逆転解析とトルク伝達特性に関する一考察

抄録

A magnetic gear using a permanent magnet was created for practical use. The magnetic gear has many advantageous performance characteristics, such as absorption of vibration, noiselessness, and oilless operation.
The angle between the driving shaft and driven shaft (the so-called intersecting spindle angle θ_i) of the magnetic bevel gear can be changed. The gear reverses at θ_i if the main contacting zone is removed. It can be used in robot arms and other industrial applications.
As a result, the driven gear is rotated normally at 0°≤θ_i≤10°, stopped at 10°<θ_i<15°, and reversed at θ_i≥15°. The transmitted torque T_G is reached the maximum value, T_G = 6.6 Nm at θ_i = 35°. The efficiency of power-transmitting η_G is 80% for the pinion speed N_P= 1500 rpm at θ_i = 0°, T_G = 5 Nm.
