[0069] 传统机械结构减速机主要由齿轮啮合传动, 存在摩擦损耗、 机械疲劳、 噪音震 动等不利因素, 且维护繁琐, 不具有过载保护能力。
[0070] 常规技术的基于磁场调制技术的轴向磁场磁齿轮减速机: 第一, 理论上, 起磁 场调制作用的调磁铁芯数必须满足约束条件, 从而导致磁性齿轮在运转传动的 任意时刻都有一半以上的永磁体磁极处于闲置的非耦合状态, 永磁体异极性磁 极的耦合面积理论上就低于 50% ; 第二, 从结构上看, 调磁铁芯的存在必然使磁 性齿轮具有两个气隙, 将消耗永磁体的大量磁动势, 导致处于耦合工作状态的 永磁体磁通量降低, 从而影响所传递的扭矩大小; 第三, 调磁铁芯的存在使得 气隙磁阻与磁势交变, 导致扭矩周期性脉动, 不仅影响传动精度, 而且调磁铁 芯所受的机械扭矩大, 其结构强度也是影响其寿命的主要因素。
[0071] 本发明中: 偏心摆动盘 3的内表面分布有 P1对极永磁体, 外圈铁芯 4的外表面分 布有 P2对极永磁体, 0 < P1-P2^3, PI、 P2为正整数。 偏心摆动盘 3和外圈铁芯 4 通过偏心轮 2安装, 偏心摆动盘 3和外圈铁芯 4之间存在气隙, 借鉴少齿差行星齿 轮传动的原理, 将转轴 1的自转通过偏心轮 2结构转换为外圈铁芯 4 (外圈铁芯 4 固定时, 偏心摆动盘 3摆动的同时公转) 的公转, 加上永磁材料 N极与 S极异极性 耦合相吸引的原理来实现偏心摆动盘 3的自转, 经输出转盘 5输出同心转矩, 起 到减速的作用, 实现无机械接触、 无摩擦的动力变速传动。
[0072] 本发明中, 以图 4剖视图中的左右为“左”、 “右”进行方位上的描述。
[0073] 对本领域的技术人员来说, 可根据以上描述的技术方案以及构思, 做出其它各 种相应的改变以及形变, 而所有的这些改变以及形变都应该属于本发明权利要 求的保护范围之内。
[0074] 需要说明的是: 以上的实施例仅仅是本发明一部分实施例, 而不是全部的实施 例。 实施例和所附权利要求书中所使用的单数形式的“第一”、 “第二”、 “一种”、
“”和“该”也旨在包括多数形式, 除非上下文清楚地表示其他含义。 “第一”和“第 二”只是为了说明的方便, 不表示有先后顺序之分。
