Description

吸振型盾构扭矩限制离合器 技术领域：
本发明属于盾构机设计技术领域，特别涉及一种可以实现动力传递分离或啮合的扭矩限制离合器。
背景技术：
目前，公知盾构机在掘进过程中，由于地层的多样性，载荷类型是多种多样的，扭矩的波动很大。电驱的盾构机动力从电机传递至减速机，在这两者之间均增加了过载离合器，当扭矩瞬间超过设备的负荷，离合器及时脱开，即主、被动端分离，有效的避免了电机、减速机等部件的损坏。在扭矩传递结构***中，采用纯刚性的结构，这种频繁的扭矩脉冲跳动，会导致过载离合器频繁脱开，大大的影响了盾构掘进效率。
基本原理如如图1和图2所示，正常状态下，处于啮合状态，过载瞬间钢球滑出凹槽，残余扭矩完全为0，主、被动端分离，不会自动复位，即使长时间运行，亦将是空转，适用于高转速场合。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已为本领域一般技术人员所公知的现有技术。
发明内容：
本发明的目的在于提供一种吸振型盾构扭矩限制离合器，从而克服上述现有技术中的缺陷。
为实现上述目的，本发明提供了一种吸振型盾构扭矩限制离合器，包括轴向套接的主动端和被动端，主动端和被动端之间设有定扭矩连接件；
主动端的内花键孔轴向套接在电机空心花键轴上；
被动端的尾部轴向固连有高吸振橡胶圈，所述高吸振橡胶圈包裹在内花键套外、并且两者之间通过连接件固定连接；
减速机花键轴贯穿电机空心花键轴后、***内花键套内与其花键连接。
在盾构机掘进过程中，载荷类型是多种多样的，尤其在沙软石岩层或其他 复杂岩层，其载荷类型呈现出脉冲跳跃的特点。而且，这些扭矩脉冲中，绝大部分脉冲扭矩大并且呈现时间较短。采用纯刚性的结构，这种频繁的扭矩脉冲跳动，会导致过载离合器频繁脱开。本设计是在传统的刚性扭矩传递***中，增加安装了具有阻尼功能的天然橡胶弹性体，这种弹性体具备很强的阻尼功能、吸振功能，可以通过其阻尼作用，对负载的扭矩脉冲进行滤波，将导致可能频繁脱开的大部分瞬时脉冲扭矩屏蔽掉，从而大幅降低了离合器的过载脱开率。
优选地，上述技术方案中，高吸振橡胶圈的径向圈体套接内花键套的外圈并且两者之间设有点状固定件；高吸振橡胶圈的轴向圈体抵接载离合器的末端，并且两者之间设有点状固定件。因为盾构机的力量是很大的所以在吸能的同时还要固定才能保证不会产生故障。
优选地，上述技术方案中，主动端的内花键孔轴向套接在电机空心花键轴上，两者通过法兰和外六角螺栓轴向限位。
优选地，上述技术方案中，减速机花键轴***内花键套花键连接，减速机花键轴的轴端用轴端挡块和内六角螺栓轴向限位。
优选地，上述技术方案中，定扭矩连接件为弹性顶针或者弹性钢球。
优选地，上述技术方案中，高吸振橡胶圈(4)的技术参数需要满足：硬度硬度：40ShA–60ShA，允许阻尼功率(W)(60℃时)：80-160，相对阻尼系数：0.6-1.2。
优选地，上述技术方案中，高吸振橡胶圈(4)为NR天然橡胶
与现有技术相比，本发明具有如下有益效果：
通过屏蔽瞬时扭矩脉冲极大程度上降低了过载脱开率，很好的解决了现有设计中存在的缺陷。

具体实施方式：
下面对本发明的具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
如图3所示，本发明主要是通过9个零件将盾构机的电机轴和减速机轴连接起来。离合器包括轴向套接的主动端和被动端(可以结合图1或者图2理解)，主动端和被动端之间设有定扭矩连接件，定扭矩连接件为弹性顶针或者弹性钢球。
主动端的内花键孔轴向套接在电机空心花键轴上，两者通过法兰1和外六角螺栓2轴向限位。
被动端的尾部轴向固连有高吸振橡胶圈4，高吸振橡胶圈4包裹在内花键套9外、并且两者之间通过连接件固定连接；高吸振橡胶圈4的径向圈体套接内花键套9的外圈并且两者之间设有点状固定件；高吸振橡胶圈4的轴向圈体抵接载离合器3被动端的末端，并且两者之间设有点状固定件。
减速机花键轴贯穿电机空心花键轴后、减速机花键轴***内花键套9花键连接，所述减速机花键轴的轴端用轴端挡块8和内六角螺栓7轴向限位。
简单来讲就是：过载离合器3内花键孔和电机轴通过花键连接，用法兰1和外六角螺栓2轴向限位；高吸振橡胶弹性体4用内六角螺栓6和内花键套9连接；再将此组件拆入过载离合器3中，用内六角螺栓5和过载离合器3连接；将减速机花键轴贯穿电机空心花键轴，***内花键套9花键连接，轴端用轴端挡块8和内六角螺栓7轴向限位。
本发明公开的吸振型盾构机过载离合器，动力从电机空心花键轴→过载离合器3→高吸振橡胶弹性体4→内花键套9→减速机花键轴。此过载离合器由若干 精密顶针均布在离合器周围，可在过载瞬间使主被动传动完全脱开(残余扭矩为0)，反应时间为5毫秒左右。各个顶针均向后弹出，消除过载后，在停机状态下，将主被动上两个标记线对齐，用塑料榔头或杠杆，对顶针实加作用力，即可使顶针复位。脱开扭矩设定值亦可在一定范围内无极调整。
关于NR天然橡胶弹性体的部分参数：
硬度：40ShA–60ShA，
允许阻尼功率(W)(60℃时)：80-160，
相对阻尼系数：0.6-1.2。
使用本发明后,如图4所示，扭矩的波动范围由约0-16000Nm,缩小至约1000-5500Nm，大为减少；波动的曲线也明显趋于平缓。
前述对本发明的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本发明限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本发明的特定原理及其实际应用，从而使得本领域的技术人员能够实现并利用本发明的各种不同的示例性实施方案以及各种不同的选择和改变。本发明的范围意在由权利要求书及其等同形式所限定。
