一种节能型大滑差永磁柔性耦合器
技术领域
本实用新型涉及永磁传动技术领域，尤其涉及一种节能型大滑差永磁柔性耦合器。
背景技术
永磁耦合器是一种利用电磁感应原理工作的传动设备，其结构中磁转子和导体盘之间设有气隙，这样就能实现电机与负载之间的非接触扭力传递。在永磁耦合器中，磁转子与导体之间的气隙为固定值，由于永磁耦合器具有节能、隔振、软启动/软刹车、过载保护、适应性强等诸多特点，在当前社会各行各业取得了广泛的应用。
由于永磁耦合器中气隙的存在，控制系统可以确保驱动电机扭矩与负载阻力的平衡，合理的功率平衡可以有效地延长整个驱动系统各部件的寿命，当负载与电机扭矩不平衡时，永磁耦合器可通过滑差来调节，因此系统中的负载的增减都能导致产生滑差，这样驱动系统的所有部件、轴承和齿轮等都将在冲击或者过载时受到保护从而延长其使用寿命。但是滑差的产生会带来导体盘的温升，过高的温升会使磁转子退磁，影响永磁耦合器的磁传递性能，因此，目前市场上的永磁耦合器产品都是工作在4%以下的滑差范围内。
发明内容
本实用新型的目的是提供一种节能型大滑差永磁柔性耦合器，克服现有技术的不足，通过完善的散热降温手段，减轻滑差现象带来的温升影响，扩展永磁耦合器在工作状态的滑差适用范围，提高永磁耦合器对高惯性负载的适应能力。
为了实现上述目的，本实用新型的技术方案是这样的：
一种节能型大滑差永磁柔性耦合器，包括导体盘、永磁盘、输入侧轮毂和输出侧轮毂，导体盘与永磁盘之间设有气隙，所述导体盘包括工作盘、散热片和盘座，工作盘依次与盘座和散热片通过螺钉相连接。
所述导体盘是由导体盘一和导体盘二构成的组件，导体盘一与导体盘二之间通过间隔支架相连接。
所述散热片是沿盘座表面环形排列的铝质单体散热片。
所述散热片为铝质环形整体式散热片。
所述散热片上的翅板具有流线角度。
与现有技术相比，本实用新型的有益效果是：通过在导体盘上加装铝质散热片，导体盘的散热降温良好，从而大大减轻了滑差现象带来的温升影响，永磁耦合器的滑差可升至15%，提高了永磁耦合器对高惯性负载的适应能力，节能率可达到20～30%。

见图2，是本实用新型一种节能型大滑差永磁柔性耦合器实施例二结构示意图，这是一种双盘结构永磁耦合器，导体盘1是由导体盘一1-1和导体盘二1-2构成的组件，导体盘一1-1与导体盘二1-2之间通过间隔支架10相连接，此结构可使电机的扭矩提高一倍。
见图3，本实用新型散热片分布实施例一结构示意图，散热片7是沿盘座8表面环形排列的铝质单体散热片，此单体散热片的优点是做为标准件，可用于多种规格耦合器产品。
见图4，本实用新型散热片分布实施例二结构示意图，散热片7为铝质环形整体式散热片，其优点是针对某种规格耦合器产品，能实现尽量大的散热面积。为了进一步增强空气的流动，散热片7上的翅板可采用流线角度设计，使导体盘旋转时，风能从翅板间流动，从而提高散热效果。
