Description

离合联轴器 技术领域

采用联轴器传动时，联轴器的两端分别连接原动机的输出轴和工作机的输入轴。当工作机的动力传输组件发生故障不能继续转动之后，原动机通过联轴器会继续带动工作机的输入轴转动，输入轴会对动力传输组件施加较大的扭矩，而动力传输组件因故障不能继续转动，继续运转可能会损坏其他零部件。但是从工作机发生故障到发现故障，再到关闭原动机，在这段时间内原动机会继续带动工作机的输入轴转动，从而给动力传输组件施加一个较大的扭矩，而损坏其他零部件。

轴套1的外侧固定环设有卡盘11，卡盘11上设置有多个通槽111，通槽111内容纳有止动件12，止动件12的第一端为锥形或球形，止动件12的第一端能够至少部分外露于卡盘11。卡爪2套设于轴套1上，卡爪2位于靠近止动件12的第一端的一侧，卡爪2能够相对于轴套1发生转动，卡爪2靠近卡盘11的端面上设置有与 止动件12的第一端相匹配的第一凹槽21，第一凹槽21的数量和位置与通槽111相匹配设置。弹性件3能够使止动件12的第一端至少部分卡于第一凹槽21内，以使卡爪2与轴套1同步转动。当卡盘11与卡爪2之间的扭矩过大时，止动件12的第一端脱离第一凹槽21，卡盘11能够相对于卡爪2转动。
该离合器联轴器使用时，轴套1和卡爪2中一个固定连接于原动机的输出轴，另一个固定连接于工作机的输入轴。本实施例中的轴套1套设固定于原动机的输出轴，卡爪2固定连接于工作机的输入轴。
弹性件3能够使止动件12的第一端至少部分卡于第一凹槽21内，使卡爪2和卡盘11连为一个整体，以使卡爪2与轴套1同步转动。原动机的输出轴带动离合联轴器转动从而带动工作机的输入轴转动。当工作机发生故障时，工作机的输入轴无法转动时，卡爪2与卡盘11之间的扭矩会增加，扭矩增加，使止动件12的第一端会脱离第一凹槽21，止动件12无法将卡盘11和卡爪2连为一个整体，卡盘11和卡爪2之间发生相对转动，即原动机的输出轴相对于工作机的输入轴发生相对转动，原动机的输出轴无法继续带动工作机的输入轴转动，不会因工作机的输入轴受到较大的扭矩而损坏工作机的其他零部件。即该离合联轴器可以呈现两种状态，卡爪2与卡盘11连为一个整体，同步转动；再就是止动件12的第一端脱离第一凹槽21，卡爪2与卡盘11发生相对转动。
在一实施例中，如图1和图2所示，卡盘11位于轴套1的中间部位，多个通槽111沿卡盘11的周向均匀布置，本实施例中的通槽111为通孔，通孔的轴线与卡盘11的轴线平行。本实施例中通槽111的数量为六个，在其它实施例中还可以为四个、五个、七个或八个等等。
在一实施例中，如图1所示，该离合联轴器还包括轴承8，轴承8的内圈套设于轴套1上，卡爪2套设于轴承8的外圈。在一实施例中，卡爪2上设置有收容槽，收容槽的端部向内环设有台阶，收容槽的内壁设置有环形槽，环形槽内设置有卡簧23，轴承8的外圈的两侧分别抵接于台阶和卡簧23，卡簧23设置于止挡轴承8的外圈，防止止挡轴承8脱落。为了防止卡爪2与轴承8的外圈发生相对转动，在卡爪2的侧壁上开设有螺纹孔，螺纹孔内设置有螺栓，螺栓的一端抵接于轴承8的外圈。
轴套1上设置有轴肩，轴套1上套设有卡圈15，轴承8的内圈的两侧分别抵接于轴肩和卡圈15。轴套1上套设有第二销圈14，第二销圈14固定于轴套1上，且抵接于卡圈15远离轴承8的一侧，卡圈15和第二销圈14相配合以止挡轴承8的内 圈。
如图3所示，卡爪2设置有第一凹槽21的一侧设置有连通相邻两个第一凹槽21的第二凹槽22，第二凹槽22的深度小于第一凹槽21的深度。当止动件12的第一端脱离第一凹槽21时，仅需要脱离至第二凹槽22位置处即可，然后在第二凹槽22内滑动。
在一实施例中，继续参照图1，该离合联轴器还包括前座4、弹簧圈挡板5、多个滚珠6及第一销圈13。前座4滑动套设于轴套1上，前座4的内径大于轴套1的外径，前座4能够沿轴套1的轴向滑动，且能够相对于轴套1转动。前座4及卡盘11的外周面上均设置有锯齿形的凸起，锯齿形的凸起具有复位作用，当离合联轴器过载后，钢珠可能没有复位，通过使锯齿形转动，使钢球复位。
止动件12的第二端抵接于前座4，弹簧圈挡板5套设于轴套1上，弹簧圈7位于前座4远离卡盘11的一侧。前座4远离卡盘11的一端设置有第一容纳槽41，弹簧圈挡板5靠近前座4的一侧设置有第二容纳槽51，第一容纳槽41和第二容纳槽51共同形成容纳腔，多个滚珠6位于容纳腔内，滚珠6的大小与容纳腔规格相关，滚珠6的数量与容纳腔的总长度相关。滚珠6的直径要保证前座4与弹簧圈挡板5之间有一定的间隙，且能够使二者发生相对转动，滚珠6能够使二者发生转动时，转动的更加顺畅。
第一销圈13套设固定于轴套1上，第一销圈13位于前座4远离卡盘11的一侧，且与弹簧圈挡板5间隔设置，弹性件3套设于轴套1上,弹性件3的第一端抵压于第一销圈13，弹性件3的第二端抵压于弹簧圈挡板5，以使弹簧圈挡板5推动前座4向卡盘11方向运动，前座4推动止动件12的第一端，使得止动件12至少部分置于第一凹槽21内，从而使卡盘11和卡爪2连为一个整体，以使卡爪2和卡盘11同步转动。
本实施例中的弹性件3为碟形弹簧，碟形弹簧的刚性比较大，需要较大的力才能使碟形弹簧发生形变，可以保证在卡盘11和卡爪2所承受的扭矩比较大，而止动件12不会脱离卡盘11的第一凹槽21，能够满足较大动力的传输。在其它实施例中还可以为普通钢弹簧。
在轴套1上套设有轴圈(参照图1和图9)，碟形弹簧部分套设于该轴圈6上。轴圈6包括两个半轴圈161，两个半轴圈161包覆于轴套1的外周，两个半轴圈161之间间隔预设距离，本实施例中预设距离为2mm。
本实施例中的止动件12为球体，球体的外径大于卡盘11的厚度。如图3所示， 第一凹槽21为与球体相匹配的第一球形槽。如图5所示，前座4靠近卡盘11的端面上设置有第三凹槽42，第三凹槽42的数量和位置与通槽111相匹配设置，第三凹槽42包括两个部分相重合的第二球形槽，第二球形槽与球体相匹配，球体部分能够卡于第二球形槽内。前座4靠近卡盘11的端面上设置有连通相邻两个第三凹槽42的第四凹槽43，第四凹槽43的截面形状为圆弧形。第四凹槽43的深度小于第三凹槽42的深度，能够使球体在第四凹槽43内滑动和滚动。球体容易发生转动，更容易脱离第一凹槽21，在卡爪2与卡盘11之间的扭矩达到设定值时，球体便可脱离第一凹槽21；而且球体比较耐磨，不易损坏。本实施例中球体的材质为碳钢，硬度比较大，当然在其它实施例中球体的材质也可以是其他硬质材料，比如硅钢等。
在其它实施例中，止动件12还可以为长杆，长杆的第一端为球形或锥形，长杆的第二端可以为球形、锥形或者柱状。当止动件12为长杆，长杆的第一端为锥形时，第一凹槽21相应地为锥形槽。当止动件12为长杆，长杆的第一端为球形时，第一凹槽21相应地为球形槽。
如图6所示，前座4远离卡盘11的一端设置有两个第一限位凸起45和一个第二限位凸起46，前座4远离卡盘11的一端设置有圆形凸台44，第一容纳槽41设置于该圆形凸台44上。第一限位凸起45和第二限位凸起46均设置于圆形凸台44上。两个第一限位凸起45与前座4的轴心距离相同，第二限位凸起46的内侧与前座4的轴心的距离大于第一限位凸起45的外侧与前座4的轴心的距离。两个第一限位凸起45和第二限位凸起46，三者中的任意两个与前座4的轴心的夹角均为120度。
如图7和图8所示，弹簧圈挡板5的外周设置有第三限位凸起52和第四限位凸起53，第三限位凸起52和第四限位凸起53呈180度夹角。第三限位凸起52与弹簧圈挡板5的轴心的距离，和第一限位凸起45与前座4的轴心距离相同。第三限位凸起52位于两个第一限位凸起45之间，第四限位凸起53位于第二限位凸起46的内侧，第四限位凸起53的宽度与第二限位凸起46的宽度相同；第四限位凸起53的外侧与弹簧圈挡板5的轴心的距离，和第二限位凸起46的内侧与前作的轴心的距离相同。
在一实施例中，如图8所示，离合联轴器还包括弹簧圈7，本实施例中包括三个弹簧圈7，在其它实施例中也可以为一个、两个或四个等。其中最内侧的弹簧圈7套设于弹簧圈挡板5、圆形凸台44及两个第一限位凸起45的外侧，该弹簧圈7的第一端卡接于第四限位凸起53的第一侧和第二限位凸起46的第一侧，所述 弹簧圈7的第二端卡接于第四限位凸起53的第二侧和第二限位凸起46的第二侧。其余的弹簧圈7依次套设于该弹簧圈7的外侧，且其余的弹簧圈7的两个自由端分别位于第四限位凸起53和第二限位凸起46的两侧。弹簧圈7对弹簧圈挡板5具有复位作用，弹性件3推动弹簧圈挡板5，使前座4复位。
弹簧圈挡板5上设置有位移监测机构，位移监测机构被配置为检测所述弹簧圈挡板5的位移量。当止动件12脱离第一凹槽21时，止动件12会推动前座4远离卡盘11，从而使弹簧圈挡板5相对于轴套1发生轴向移动，此时位移监测机构传递信息给原动机控制系统，原动机控制系统操控原动机停止运行，待工作机故障排除之后，再原动机使工作机正常运行。本实施例中的位移监测机构为位移传感器，在其它实施例中还可以为限位开关。
在一实施例中，如图1所示，该离合联轴器还包括离合器壳体9和钢丝提环131。离合器壳体9套设于碟形弹簧的外侧，离合器壳体9的一端卡于第一销圈13上，或螺纹连接于第一销圈13上。离合器壳体9对碟形弹簧具有保护作用，防止其他硬质杂物掉落至碟形弹簧内，影响碟形弹簧的性能。钢丝提环131两端卡于所述第一销圈13上，钢丝提环131便于取放该离合联轴器。
该离合联轴器正常使用时，碟形弹簧能够作用于弹簧圈挡板5，从而作用于前座4，使前座4推动球体，使球体部分卡于第一球形槽内，使卡爪2和卡盘11连为一个整体，从而使卡爪2与轴套1同步转动。原动机的输出轴带动轴套1转动，从而带动卡爪2与轴套1同步转动，进而使工作机的输入轴与原动机的输出轴同步转动，原动机正常驱动工作机运行。
当工作机发生故障时，工作机的输入轴无法转动时，卡爪2与轴套1的卡盘11之间的扭矩会迅速增加，扭矩增加使球体脱离第一球形槽，会使前座4及弹簧圈挡板5向远离卡盘11的方向运动，以使球体能够脱离第一球形槽，此时碟形弹簧受挤压力，原动机继续带动卡盘11转动，球体在第一球形槽和第二凹槽22内滑动，卡盘11相对于卡爪2发生转动，卡爪2由于工作机的故障而不发生转动。原动机此时不带动工作机发生转动，不会损坏工作机的其他零部件。弹簧圈挡板5向远离卡盘11的方向运动时，位移监测机构会检测到，并将信号传传递信息给原动机控制系统，原动机控制系统操控原动机停止运行。
