Description

一种带液压执行机构的水冷型永磁调速装置
技术领域
本发明涉及永磁传动领域，尤其涉及一种带液压执行机构的水冷型永磁调速装置。
背景技术
目前的水冷型永磁调速装置中的执行器多为蜗轮蜗杆调节机构，见附图1，在永磁调速装置的输出轴（1）上设有气隙调节套（2），气隙调节套（2）的一端连接永磁盘（4），气隙调节套（2）外侧的滑套（20）通过螺纹与蜗轮套筒（3）的内径相配合，旋转蜗杆（6）即可拨动蜗轮套筒（3）实现永磁盘（4）与导体盘（5）之间的气隙宽度的调节，从而实现永磁调速传动。这种蜗轮蜗杆机构的优点是可实现无极调速且可随时保持永磁盘的自锁定位，但是同时也存在占用空间大且制作成本高的不足，使水冷型永磁调速装置产品的体积过大，造成使用受限，亟待改进。
发明内容
本发明的目的是提供一种带液压执行机构的水冷型永磁调速装置，将液压控制技术应用于水冷型永磁调速装置的执行机构中，既能实现气隙的无级调节要求，又能满足永磁盘的定位自锁，减少空间体积，降低产品造价。
为了实现上述目的，本发明的技术方案是这样的：
一种带液压执行机构的水冷型永磁调速装置，包括输入轴、输出轴、永磁盘、导体盘、气隙调节套、滑套以及壳体，输入轴的一端设有导体盘，输出轴的一端设有永磁盘，输出轴上设有气隙调节套，气隙调节套外侧通过轴承与滑套相连，输入轴与壳体前侧之间设有轴承组一，输出轴与壳体后侧之间设有轴承组二，整个壳体为封闭结构，中间设有隔板将装置分为磁力工作区和执行控制区，其特征在于，所述执行控制区内，滑套的外侧设有控制摆杆，控制摆杆的一端为固定铰接端，控制摆杆的另一端与液压缸的活塞端铰接，控制摆杆本体通过配合孔与滑套两侧的销轴铰接，所述配合孔为垂直输出轴轴向的长孔。
所述液压缸为数字式液压缸。
所述控制摆杆的另一端与液压缸的活塞端之间设有球铰接头。
与现有技术相比，本发明的有益效果是：
1）创造性地将液压精密控制技术应用于水冷型永磁调速装置的执行机构中，数字式液压缸既能实现气隙的精确无级调节，又能满足永磁盘的定位自锁要求；
2）执行机构得以精简优化，去除了结构复杂、加工精度要求高的蜗轮蜗杆机构，不但整个装置的空间体积明显缩小，还明显降低产品的造价，提高产品的市场竞争力。
附图说明

具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明：
见图2、图3，是本发明一种带液压执行机构的水冷型永磁调速装置的实施例结构示意图，包括输入轴7、输出轴1、永磁盘4、导体盘5、气隙调节套2以及壳体8，输入轴7的一端设有导体盘5，输出轴1的一端设有永磁盘4，永磁盘4、导体盘5之间设有气隙17，输出轴1上设有气隙调节套2，气隙调节套2外侧通过轴承与滑套20相连，输入轴7与壳体8前侧之间设有轴承组一9，输出轴1与壳体8后侧之间设有轴承组二10，整个壳体8为封闭结构，中间设有隔板11将装置分为磁力工作区12和执行控制区13，在执行控制区内，在滑套2的外侧设有控制摆杆14，控制摆杆14的一端为固定铰接端，实施例中与壳体8内壁铰接，控制摆杆14的一端与壳体8内壁的铰接点可为壳体内壁的圆周向任一处，而不局限于实施例中的顶部，同时控制摆杆14的一端也可铰接在其他固定物上，比如支撑架之类。控制摆杆14的另一端与液压缸15的活塞端铰接，为了减少摩擦力，控制摆杆14的另一端与液压缸15的活塞端之间设有球铰接头19。
控制摆杆14本体通过配合孔18与滑套2两侧的销轴16铰接，为了使控制摆杆14的活动顺畅，配合孔18为垂直输出轴轴向的长孔，以补偿控制摆杆14摆动时与销轴16之间的相对位置变化。
为了提高对气隙的控制精度，液压缸15选用先进的数字式液压缸，这种液压缸是当前自动化和数字化技术在液压领域发展的代表，其内部设计组合有步进或伺服电机、液压滑阀和闭环位置反馈元件，接通液压油源后，所有功能直接通过数字缸控制器或计算机或可编程逻辑控制器（PLC）发出的数字脉冲信号来完成活塞伸出长度的矢量控制。其中电脉冲的频率与油缸活塞的运动速度相对应，电脉冲的数量与油缸活塞的行程相对应，这样用一台微机或可编程逻辑控制器（PLC）就可以完成液压缸的多点、多速控制，也可完成多缸的同步、插补运动，此功能有助于实现电机的软启动以及负载速度的程序控制。
