  • Threaded sub-mechanical static joints between objects have some bolts broken at key parts, safety problems caused by failure of threaded connections and safety accidents, which are often encountered in the world, and are a common problem faced by technicians in the field. Solve the problem that has not been solved. Small bolts, large accidents, and frequent major accidents due to bolt breakage, such as the collapse of the connecting rod bolts of the engine of the automobile; the accident of 1 death and 4 injuries caused by the break of the bolts of Harbin tower crane on April 18, 2009; Taiwan's media reported that the No. 1 reactor of the No. 2 Plant of the Nuclear Power Plant detected 7 anchor bolt breaks and damages that may cause nuclear safety accidents; the guidance of the No.
  • the reliability of the threaded connection is ensured by the self-locking of the friction of the thread pair and the friction between the contact faces of the thread pair.
  • the connecting thread has a certain self-locking property and does not automatically loosen under static load conditions.
  • the friction between the pairs of threads will disappear or decrease instantaneously; at the same time, in the case of high temperature or temperature changes, the material will creep and stress relaxation, and the friction will be reduced. Under multiple actions, the threaded connection is gradually released.
  • the main reason for the failure of the threaded connection is that the thread is loose due to the reduction of the pre-tightening force. Therefore, the essence of the threaded connection is to prevent the reverse rotation of the thread pair (that is, the reverse between the threaded hole and the external threaded portion). Such as the reverse between the bolt and the nut.

  • the gasket is installed outside the outer hexagonal head, and the gasket and the screw are two separate members. Since the gasket is a part of the screw, during the screwing process of the screw, the anti-loose teeth on the gasket and the gasket also rotate with the screw, so that although the anti-loose teeth are provided on the gasket, the anti-loose teeth are embedded.
  • the connected object is not only embedded in the axially connected object, but in the process of rotation, the axial and circumferential displacements are embedded in the connected object, so that the anti-loose teeth will be connected to the connected object during the rotation of the screw.
  • the surface forms a circumferential groove that is shallower and deeper in the direction in which the screw is screwed.
  • the circumferential groove destroys the appearance of the connected object; on the other hand, the insertion force of the anti-loose tooth and the connected object is greatly reduced, and it can be said that the anti-loose effect of the anti-loose tooth on the screw is very limited; In particular, due to the presence of the embedded teeth, it is difficult for the screws to lock the connected objects. Therefore, the locking teeth of the screw of this structure can not play the role of relaxation, and the screw of this structure has no use value.

Description

一种紧固连接组件及紧固连接结构、轨道结构 技术领域:
本发明涉及一种螺纹副机械静联接两个以上的物体的紧固连接技术;特别是涉及一种通过螺纹副机械静连接曲轴连杆机构、轨道结构、飞机、船舶、设备、航空航天设备、航母、飞船、火箭、发动机、核反应设备、火车、高铁、铁轨、钢结构建筑、钢结构桥梁、汽车等等机械设备上的关键部位上的机械零件的紧固连接组件及紧固连接结构、轨道结构,这些机械零件的使用环境特别恶劣如震动大、高温环境、载荷大等,且对螺纹副机械静连接的连接可靠性要求特别高。
背景技术
物体间的螺纹副机械静联接出现一些关键部位连接的螺栓断裂、螺纹连接的失效引起的安全问题和安全事故,经常碰到,是全球面临的通病,也是本领域的技术人员不断研究改进急待解决还没有解决的问题。小螺栓、大事故,经常因螺栓断裂发生重大事故,如汽车的发动机的连杆螺栓断裂造成捣缸事故;2009年4月18日发生的哈尔滨塔吊螺栓断裂造成的1死4伤的事故;据台湾媒体报道的核二厂一号机反应炉检出7支锚定螺栓断裂、毁损可能引起核安全的事故;2012年6月29日16时45分发生的、5号座舱支撑系统的中导柱螺栓发生疲劳断裂、造成深圳东部华侨城“太空迷航”娱乐项目发生6人死亡、10人受伤的重大安全事故;作为高端车辆的代表厂家,因无法解决螺丝断裂的技术问题,导致宝马发动机因螺丝断裂瞬间失去动力熄火事件导致召回23万辆车(宝马(中国)汽车贸易有限公司、华晨宝马汽车有限公司决定自2014年6月18日起,召回23万辆车),制造厂家受到巨大经济损失和商誉损失,更严重的是会造成车主的生命财产安全。虽然在很多情况下,特别是在振动状态下,经常需要对已经锁紧的紧固连接件定期检修加固,防止螺纹副反转松动甚至是松脱带来的安全事故,但全世界每年因为螺纹连接失效导致的一系列安全事故非常多,例子不胜枚举。
螺纹连接的可靠性是靠螺纹副的摩擦产生自锁以及螺纹副的接触面间的摩擦来保证。一般来说,连接螺纹具有一定的自锁性,在静载荷条件下并不会自动松脱。但是,由于连接的工作条件不可避免地会存在冲击、振动、变载荷作用。在这些工况条件下,螺纹副之间的摩擦力会出现瞬时消失或减小;同时在高温或温度变化比较大的场合,材料会发生蠕变和应力松弛,也会使摩擦力减小。在多次作用下,就会造成螺纹连接的逐渐松脱。
螺纹连接的失效,主要原因是由于预紧力减少导致螺纹松脱,因此螺纹连接防松的本质,就是防止螺纹副的反转(也就是内螺纹孔与外螺纹部之间的反转),如螺栓与螺母间的反转。
现有的机械机械防松方法主要包括利用开口销、止动垫片及串钢丝绳等机械防松方法。现在飞机上很多还采用串联钢丝绳的防松方法。
为了防止螺纹连接松脱,人们一直在不懈努力。
专利号为US1755807、申请日为1929年4月6日、公开日为1930年4月22日的美国专利中,公开了一种防松的螺杆螺母结构,包括螺杆、锁紧螺母、止转套。锁紧螺母内设有螺纹通孔和与其连通的内齿轮形的止转孔,止转孔的最小孔径大于螺纹通孔的孔径。止转套设有止转通孔,止转套外周为外齿轮形,止转通孔孔壁上设有止转条,在螺杆上设有与止转条配合的止转槽。止转套的外齿轮形外周与锁紧螺母止转孔内齿轮型孔壁配合约束锁紧螺母相对止转套旋转,止转套的止转套插入螺杆的止转槽约束螺杆相对止转套旋转,因此螺杆与锁紧螺母不可转动地安装在一起。该专利中,由于止转套完全容置在锁紧螺母的止转孔中,止转套很难从锁紧螺母的止转孔中取出;而且在螺杆、螺母的使用过程中,由于止转套、螺杆和螺母生锈、灰尘进入止转套与螺杆和螺母间、止转套与螺杆和螺母的相互渗透等会造成止转套与螺杆螺母间产生很大的咬合力,从而造成止转套无法从螺杆与螺母间取出。如果止转套很难或无法从螺杆与螺母间取出,就很难或无法将螺母和螺杆分离,因而却失去了使用螺纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,因而这种螺杆和螺母结构是没有多大的使用价值。
专利号为ZL201510198765.5、申请公布号为CN 104819197A、申请日为2015年4月24日、公布日为2015年8月6日的发明专利中,一种防松动螺母连接结构,包括连接件及穿过连接件的螺杆,螺杆上旋合螺母将连接件紧固,螺母外侧套接一防松套圈,防松套圈与连接件间设有防旋转结构,防旋转结构包括连接件上对应螺母设置的沉槽,螺母旋合后底部设于 沉槽内,防松套圈外圈设有卡头,沉槽内侧壁设有供卡头卡入的卡槽;防松套圈高度小于沉槽的高度,防松套圈与螺母和沉槽之间为过盈配合。该发明的防松动螺母连接结构,由于增加了一个防松套圈,且防松套圈与连接件间设有防旋转结构,防松套圈内圈为与螺母配合的正六边形结构,防松套圈内圈与螺母间不能相对旋转,同时防旋转结构防止防松套圈与连接件相对旋转,因而可以防止螺母紧固后松动。这种防松动螺母连接结构,虽然实现了防止螺母的松动,但一方面由于防松套圈高度小于沉槽的高度、防松套圈与螺母和沉槽之间为过盈配合,在拆卸防松动螺母连接结构时,防松防松套圈是无法从沉槽内取出,无法取出防松防松套圈,就无法将螺母和螺杆分离,因而却失去了使用螺纹副连接就是为了能够很方便地将螺杆和螺母分离的最基本用途,,因而这种结构是没有任何意义的;另一方面,沉槽内侧壁设有供卡头卡入的卡槽,这种卡槽结构无法机械加工出来,如果不是事先与被连接件一起成型,则需要用电火花等工艺才能加工出来,因而使用成本特别高;还有,如果不对螺杆止转,螺杆相对锁紧螺母还是会转动,只对螺母止转也是没有任何现实意义。上述种种原因,会使本领域的技术人员认为该发明的技术方案无任何使用价值,大大阻碍了本领域的技术人员改进该专利的技术方案的积极性。
专利号为ZL97112246.6、公开日为97112246.6的发明专利中,公开了一种防松螺母,包括工具安装部及与其同轴向上突出设置的环形突出部,它们中间有贯通的螺纹孔。这种防松螺母,就是HardLock螺母,号称世界上唯一的绝不松动的螺母,是哈德洛克工业株式会社的社长若林克彦用了近20年的时间,通过不断技术改进而研究出来的技术成果,现在高铁上应用比较多。高铁运营时,高速行驶的列车和铁轨不断接触,形成的震动非常大,一般的螺丝在这种震动中会被震松震飞。不想被震飞,那么就需要螺丝和螺母丝丝入扣,永不松动才行。这个要求看起来很简单,但是要满足它并不容易。高铁代表中国创造,却用日本螺母,因而有媒体发出类似从一颗螺母看出中国制造和日本制造的差距的感叹。但这种螺母制造工艺非常复杂,制造精度要求特别高,现在的情况是,有产品图、有产品,没有哈德洛克公司的独特的技术和诀窍,却无法制造出来,因而价格昂贵,一个至少几十元钱;这种螺母也无法做到完全不松,只是在现有的防松螺母中防松效果算很好的;这种螺母,重复使用几十次后就不能再用。
专利号为ZL201520399393.8的实用新型专利中,公开了一种自紧螺母、螺栓紧固件,紧固件包括自紧螺母本体、自紧垫圈和普通螺栓;自紧螺母本体与自紧垫圈接触面为平滑过渡的螺旋面;自紧螺母本体与普通螺栓螺纹连接;螺栓紧固件包括自紧螺栓、自紧垫圈和普通螺母;普通螺母与自紧螺栓螺纹连接。该自紧螺母、螺栓紧固件,采用自紧原理,在螺母或螺栓上设置一自紧结构,使其锁紧后达到自紧的效果,让螺母不再出现移位或者松动。这种自己螺母,又称自紧王螺母和永不松动的螺母,并宣称其防松能力超过hardlock螺母,在央视中有报道。这种螺母由于没有广泛使用,其防松效果如何,无法判断。
公开号为CN201934467U、公开日为2011年8月17日的实用新型专利中,公开了一种前端单螺纹螺旋式后双线锚固螺钉,它主要包括螺杆,螺杆上设有自攻螺纹,螺杆尾端设有连接结构件,连接结构件为外六角头,外六角头上设有垫片,垫片底部设有防松齿。该实用新型中,公开的仅是一种螺钉结构,所描述的所有结构均是螺钉结构的一部分,从图和外六角头上设有垫片的文字表达上来看,均可以毫无异议理解为垫片是螺钉的一部分,故不存在在垫片上设有与外六角头配合的止转通孔,垫片安装在外六角头外,垫片与螺杆是分开的两个构件。由于垫片是螺钉的一部分,在螺钉的旋入过程中,垫片及垫片上的防松齿也随着螺杆一起旋转,这样虽然在垫片上设有防松齿,防松齿在嵌入被连接的物体时并不是仅轴向嵌入被连接的物体,而是在旋转的过程产生轴向和周向位移嵌入被连接的物体,这样在螺钉旋转的过程中防松齿会在被连接物体的表面形成一条沿螺钉旋入方向由浅渐深的周向槽。周向槽一方面破坏被连接物体外观的美观;另一方面大大减小防松齿与被连接的物体的嵌入力,可以说防松齿对螺钉的反向防松脱作用是十分有限的;特别是由于嵌入齿的存在,使螺钉很难锁紧被连接的物体。因此这种结构的螺钉的防松齿,是起不了放松的作用的,这种结构的螺钉,是没有任何使用价值的。
从专利号为US1755807、申请日为1929年4月6日的美国专利中,发明了用止转套来限制螺栓相对螺母转动的防松技术,到专利号为ZL201510198765.5、申请日为2015年4月24日的中国发明专利中,再次提出止转套来限制螺母转动的技术方案,历时八十六年,都没有解决既能用止转套对螺栓和螺母防松或用止转套对螺栓和螺母防松、又能方便快速可靠的将止转套从止转孔中取出从而使螺栓和螺母拆离的技术问题。现有的认为防松效果好的hardlock螺母、自紧王螺母,都不是通过采用止转套阻止螺母转动来实现螺栓螺母防松;快 一个世纪过去了,还没有通过采用止转套阻止螺母转动来实现螺栓螺母防松的技术应用;可见,人们陷入了虽然采用止转套能阻止螺母转动来实现螺栓螺母防松、但螺栓螺母却很难或无法拆卸的技术误区,形成了采用止转套阻止螺母转动来实现螺栓螺母防松的技术无使用价值的惯性思维,从而阻止了本领域的技术人员改进采用止转套阻止螺母转动来实现螺栓螺母防松的技术方案的积极性。
上述现有技术的紧固连接结构,都是需要将止转套置于止转孔中约束锁紧螺母相对螺杆反转。缺点是如果止转套完全容置在止转孔中,如果又没有将止转套从止转孔中取出的取出结构,止转套很难从止转孔中取出;还有,需要在附体上加工与止转套配合的止转孔,或需要一个与附体不可转动地安装在一起的止转件,在止转件上加工与止转套外周配合的止转孔,成本高。

本发明的有益效果是:
既要阻止螺纹副反转防松,又要保持机械螺纹连接的方便、快速、可靠地可拆卸性,是人们一直长期以来致力解决却没有彻底解决的技术难题。
本发明通过止转套的止转凸部直接被附体抵挡约束止转套相对附体,止转套再约束螺母或螺杆相对止转套旋转,从而防止螺纹副反转松脱。本发明的紧固连接结构,不需要与止转套外周配合的止转孔约束止转套相对附体旋转,也不需要在附体上加工与止转套配合的止转孔,或需要一个与附体不可旋转地安装在一起的止转件,在止转件上加工与止转套外周配合的止转孔,并且不需在附体上加工任何约束止转套旋转的止转结构,只需利用附体现有的结构与止转套的止转凸部或止转凸部配合就可约束止转套相对附体旋转,因而大大降低成本;由于止转套没有止转孔的约束,完全外露,因而不需要借助任何工具、止转套的拆卸快速、方便、可靠,。
止转套与螺杆的抵挡部或锁紧螺母的配合结构为齿轮形、华健形或正多边形等。
采用本发明的紧固连接组件的轨道结构,通过紧固连接组件固定在一起的弹条和垫板,由于螺杆相对垫板、预埋套管不会旋转,因此即使弹条承受很大地力、或轨道结构处于剧烈震动的环境,螺杆和预埋套管的连接也很可靠,不会因为螺杆与预埋套管的螺纹连接副反转松脱导致螺纹连接失效,这样确保弹条可靠地压住绝缘块、绝缘块可靠地压住导轨,导轨可靠地与垫板安装在一起,防止事故发生。
利用垫板外侧与止转套止转凸部配合约束止转套相对垫板旋转,不需再垫板上再设计其它止转结构,只需在垫板外周设有与止转套的止转止转凸部配合的止转平面即可,结构简单,相对于没有止转结构的轨道结构,只需在设计垫板与螺杆上的通孔时,通孔的轴线到垫板的止转平面的距离稍小于止转套止转凸部的抵挡面至止转套轴心的距离。
利用垫板本身的抵挡部约束止转套相对垫板旋转,止转套结构简单,只需在止转套外周设有与垫板配合的止转平面即可。
轨道结构,包括用于承载轨道的垫板、导轨、导轨压件、紧固连接组件,在导轨压件上设有第一止转孔,不需要再增加第一止转件,结构简单;利用垫板的抵挡凸部与导轨压件的U形槽配合约束导轨压件相对垫板旋转,不需要再设计对导轨压件的止转结构。
轨道结构,包括用于承载轨道的垫板、轨下垫板、导轨、绝缘块、弹条、紧固连接组件;紧固连接组件包括螺杆、锁紧螺母、第一止转件。利用第一止转件的两个止转凸部被弹条相背的两侧抵挡约束第一止转件相对弹条旋转,不需要再设计对第一止转件的止转结构,结构简单,成本低。
