  • 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 threaded connections need to be tightened.
  • the connection force between the threaded connection pairs is mainly manifested by the static friction generated by the pre-tightening force when tightening the nut and the bolt. Therefore, for the threaded connection of key objects, the preload force must be controlled to ensure the reliability of the work. If the pre-tightening force is too large, the static load of the screw increases, and the strength of the threaded copy body is reduced. The pre-tightening force is too small and the work is not reliable.
  • the second is the failure of the threaded connection caused by common fatigue damage.
  • the threaded connection is subjected to an alternating load and the pre-tightening force in the connection causes the connection to be loose.
  • the cyclic alternating load acts on the bolts that are only connected, the bolts are fatigue cracked or even broken due to the large alternating stress. Fatigue failure usually occurs in areas where stress concentration is severe, such as: screw head, thread closing end, thread at the screw support plane, and transition corners of the screw.
  • the third is the creep that causes the threaded connection to fail at high temperatures.
  • Creep refers to the slow plastic deformation of a metal material over a long period of time under constant temperature and constant stress. Creep can occur at stresses that are less than the yield limit of the material. At low temperatures, creep is not obvious, only when a certain temperature (about 3/10 of the material melting temperature) is reached It is remarkable. Creep can cause failure of the threaded connection at high temperatures. In order to eliminate creep, compensation measures are taken when the connection is assembled at room temperature, such as increasing the preload, or pre-tightening the bolts.
  • fretting wear causes failure of the threaded connection. Fretting wear is caused by a surface that is subjected to heavy loads and with little relative motion on the other surface. Threaded connections that carry vibration are most susceptible to fretting wear.
  • the failure mode of the above four main threaded connections is mainly due to the looseness of the thread due to the reduction of the pre-tightening force. Therefore, the anti-loose nature is to prevent the relative rotation of the thread pair (that is, the internal thread hole and Relative rotation between the externally threaded portions, such as relative rotation between the bolt and the nut.
  • Frictional anti-loose generally include the use of gaskets, self-locking nuts and double nuts. Frictional anti-loose is not reliable, and mechanical anti-loose methods are used for important threaded connections. Mechanical anti-loose and anti-loose anti-loose are called detachable anti-loose. Common mechanical anti-loose methods: the use of split pins, stop pads and string wire ropes.
  • Mechanical anti-loose mainly includes the following ways:
  • the pin hole can be drilled with a normal nut.
  • the disadvantage of this mechanical anti-loose method is that the first pin hole is drilled in the tail of the bolt, which affects the strength of the bolt; the second bolt cannot be too small, otherwise the pin hole cannot be drilled; thirdly, the groove on the nut needs to be opened. Pin fit, the width of the groove should not be too small, which greatly limits the number of slots on the nut.
  • the fourth structure is only suitable for the anti-loose between the bolt and the nut, and the case of connecting the parent body and the attached body with screws. Unusable or inconvenient to use;
  • the second is to use a round nut to stop the gasket to prevent loosening or to use a retaining gasket to prevent loosening.
  • the disadvantage of these two mechanical anti-loose methods is that the first need to machine the groove on the bolt or the shaft, which weakens the front degree of the bolt or the shaft; the second round nut stop washer needs to be thin to fold the outer tongue of the gasket Embedded in a groove of the nut, the outer tongue of the round nut stop washer can bear little force, and when the outer tongue of the gasket is subjected to a large shearing force from the nut, the outer tongue of the gasket is easily broken, thereby making the circle
  • the nut stop washer loses the anti-rotation effect, and the anti-rotation effect is not good; in the third disassembly, the outer tongue of the gasket needs to be folded again and kept in the same plane as the round nut stop washer, and the outer tongue of the gasket is deformed very much. It is difficult to achieve this requirement, so it is difficult to disassemble; when the fourth round nut stop washer is repeatedly used, the outer tongue of the gasket can be greatly reduced or broken due to repeated deformation
  • the third is to use a series of steel wire to prevent loosening.
  • the disadvantage of these two mechanical anti-loose methods is that more than two screws are needed to prevent loosening, and it is impossible to achieve the anti-looseness of the single bolt.
  • the rotation retracting torque of the nut is large enough to cut the outer tongue of the wire or the cotter pin or the retaining washer, so that the reliable operation of the nut cannot be guaranteed.

  • the shape of the ear is reversed, and the shape of the anti-retracting ear corresponds to the shape of the retaining groove, and the anti-retracting ear and the 0-ring can be fitted in the annular groove.
  • the utility model can prevent the front end nut from being retracted by the inner step of the anti-drop lever on the retaining sleeve, and the restraining nut is reversed, thereby reducing the screw connection failure caused by the nut reversal, and the thread connection is reliable.
  • the nut anti-loose structure of the structure is arranged when the back of the ferrule is aligned with the retaining groove of the retaining sleeve and the splitting cone of the splitter cone, and the ferrule is subjected to the force in the direction of the splitter cone, and the thrust is sufficient to cut off

一种紧固连接组件及结构、安装及拆卸方法、曲轴连杆机构、轨道结构、骨连接装置及骨连接方法 技术领域:
本发明涉及一种机械静联接两个以上的物体的紧固连接组件、紧固连接结构及连接方法、拆卸方法,以及使用紧固连接组件的曲轴连杆机构、轨道结构、、骨连接装置及骨连接方法;特别是涉及一种可机械静联接飞机、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、汽车等等机械设备关键部位上的高要求、恶劣环境使用或载荷大的连接机械零件的紧固连接组件、紧固连接结构及连接方法、拆卸方法。
背景技术
物体间的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***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等等,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。
螺纹连接都需要拧紧。螺纹连接副之间的连接力,主要表现为拧紧螺母和螺栓时的预紧力产生的静摩擦力。因此对关键物体的螺纹连接,必须控制预紧力的大小,以保证工作的可靠性。预紧力过大,螺杆静载荷增大,降低螺纹连接副本身的强度。预紧力过小,工作不可靠。
参考连祖虎发表的“螺纹连接的失效形式及原因分析”一文的分析,螺纹连接的失效形式及原因分析具体为以下几个方面:
一是因载荷过大引起的螺纹连接的失效。螺纹连接的螺栓和螺母在拧紧时,螺栓因承受拉力引起伸长,导致螺母支承面附近的螺纹承受很大载荷,而且螺母承受的压缩载荷也产生同样的载荷集中。外载增加时,螺栓继续弹性伸长,被连接件压缩变形相应减小(即紧固力减小),甚至消失;或因螺栓伸长(应变)超过了弹性极限,因塑性屈服而产生永久变形,使预紧力减少,导致连接失效(畸变、断裂、丧失紧密性等)。
二是常见的疲劳破坏导致的螺纹连接的失效。螺纹连接受交变载荷作用会使连接中的预紧力变化导致连接松脱。当循环交变载荷作用在仅连接的螺栓上时,螺栓因收较大的交变应力产生疲劳裂纹甚至断裂。疲劳失效通常发生在应力集中较严重的地方,如:螺杆头部、螺纹收尾部、螺杆支撑平面所在处的螺纹、螺杆的过渡圆角处等。
三是高温下导致螺纹连接失效的蠕变。蠕变是指金属材料在恒定温度和恒定应力的长期作用下,随着时间的延长材料缓慢地发生塑性变形。蠕变可以在小于材料的屈服极限的应力下发生。在低温下,蠕变并不明显,只有达到一定的温度(材料熔化温度的3/10左右)才变 得显著。蠕变会导致高温下的螺纹连接失效。为了消除蠕变,当连接在室温下装配时采取补偿措施,如提高预紧力、或对螺栓再预紧等。
四是微动磨损导致螺纹连接的失效。微动磨损是由一承受重载荷的表面,在另一表面上做很小相对运动造成的。承载振动的螺纹连接最易产生微动磨损。
从上面的分析可知,上述四种主要的螺纹连接的失效形式,主要原因是由于预紧力减少导致螺纹松脱,因此防松的本质,就是防止螺纹副的相对转动(也就是内螺纹孔与外螺纹部之间的相对转到),如螺栓与螺母间的相对转动。
常用的防松方法有三种:摩擦防松、机械防松和永久防松。永久防松称为不可拆卸防松,常用的永久防松有点焊、铆接、粘合等。这种方法在拆卸时大多要破坏螺纹紧固件,无法重复使用,不适合螺纹连接需拆卸后重复使用的场合。
常见摩擦防松一般包括利用垫片、自锁螺母及双螺母等。摩擦防松不可靠,对于重要的螺纹连接要使用机械防松的方法。机械防松和摩擦防松称为可拆卸防松。常见的机械防松方法:利用开口销、止动垫片及串钢丝绳等。
机械防松主要包括以下几种方式:
一是利用槽形螺母和开口销防松。槽形螺母拧紧后,用开口销穿过螺栓尾部小孔和螺母的槽,也可以用普通螺母拧紧后进行配钻销孔。这种机械防松方法的缺点是,第一在螺栓尾部钻配销孔,影响螺栓的强度;第二螺栓不能太小,否则无法钻配销孔;第三由于螺母上的槽需与开孔销配合,槽的宽度不能太小,这样大大约束了螺母上的槽的个数,螺栓拧紧在最佳预紧力的情况下,需正转或反转较大的角度才能使螺母上的槽与螺栓上的孔正对,这样会导致螺纹连接的预紧力过大或过小;第四这种结构仅适用于螺栓与螺母之间的防松,对用螺钉连接母体和附体的情况,无法使用或用起来不方便;。
二是采用圆螺母止动垫片防松或采用止动垫片防松。采用圆螺母止动垫片防松,使垫片内舌嵌入螺栓(轴)的槽内,拧紧螺母后将垫片外舌之一翻折嵌于螺母的一个槽内。采用止动垫片防松,螺母拧紧后,将单耳或双耳止动垫圈分别向螺母和被连接件的侧面折弯贴紧,实现防松;如果两个螺栓需要双联锁紧时,可采用双联止动垫片。这两种机械防松方法的缺点是,第一需在螺栓或轴上加工槽,削弱了螺栓或轴的前度;第二圆螺母止动垫片需较薄才能将垫片外舌翻折嵌于螺母的一个槽内,圆螺母止动垫片的外舌能承受的力很小,垫片外舌在到来自螺母较大的剪切力时,垫片外舌易断裂,从而使圆螺母止动垫片失去止转作用,止转效果不好;第三拆卸时需将垫片外舌再翻折与圆螺母止动垫片保持在同一个平面内,垫片外舌由于变形很难达到这种要求,因此很难拆卸;第四圆螺母止动垫片重复使用时垫片外舌由于反复变形,能承受的力大大减少或断裂,无法多次重复使用。
三是采用串联钢丝防松。用低碳钢钢丝穿入各螺钉头部的孔内,将各螺钉串联起来,使其相互制动。这两种机械防松方法的缺点是,需两个以上的螺杆才能防松,无法实现单个螺栓的防松,安装时还需要注意钢丝穿入的方向,安装不方便,防松效果不好。
上述几种机械防松方法,螺母的旋转退扣力矩大到一定程度都会将铁丝或者开口销或止动垫片的垫片外舌剪断,从而不能保证螺母的可靠工作。
还有一种重要的防松方法,就是提高螺栓螺母的抗拉强度,从4.9级、8.8级、10.9级、12.9级、14.9级一直不断提高,但这也不是终极好办法,即使螺栓螺母可以不断的提高抗拉强度,可是被连接件的内螺纹受制于成本及使用要求等限制不可能相应的提高抗拉强度,因此就会导致新的应力不平衡产生破坏性失效,会破坏被连接件内的螺纹导致螺纹连接其失效等。
申请号为201320630115.X的实用新型专利中,公开了一种了螺母防松结构,在该螺母防松结构中的防掉拉杆一端为与螺母对应的螺纹结构,止退套的内表面设置有内台阶,防掉拉杆的对应位置上设置有卡槽,在止退套外表面的前端设置有环形开槽,环形开槽的边沿上设置有止退槽,卡套设置有向内突起的防退耳,防退耳的形状与止退槽的形状对应,防退耳以及0形圈可嵌合在环形开槽内。本实用新型能够通过止退套上的内台阶卡入防掉拉杆的卡槽对前端螺母防退,约束螺母反转,减少因螺母反转导致螺纹连接失效,使螺纹连接可靠。这种结构的螺母防松结构,当卡套的退耳与止退套的止退槽、分流锥的分流锥槽对齐,同时要卡套须受到朝分流锥方向的力,推力足够剪断止退环开槽内的0形圈时,卡套要滑出分流锥,使止 退套轴向滑脱出分流锥之外,止退套失去止退作用。因此这种螺母防松结构,防松不可靠,还有结构比较复杂。

止转抵挡部的第一止转部置于相应的第一止转孔的第四止转部内,止转抵挡部的第一止转部与相应的第一止转孔的第四止转部位置关系对应;
将止转套安装在相应的螺杆的第一止转部外和第一止转孔的第四止转部内,将止转套限位件安装在相应的螺杆上或连接件上使止转套被轴向限位在螺杆的第一止转部外和第一止转孔的第四止转部内;第一止转部与第二止转部配合约束螺杆相对止转套旋转,第三止转部与第四止转部配合约束止转套相对连接件旋转。
本发明的有益效果是:
因第二止转部与第一止转部配合约束螺杆相对止转套旋转,止转套与附体不可转动地安装在一起,螺杆不可转动地与母体和附体安装在一起,螺杆就不会因为反转而松脱,使螺杆保持在最初需要的锁紧位置,螺纹连接的夹紧力在使用过程中基本无变化;即使采用普通的螺钉,在剧烈震动、高温等恶劣环境下,螺杆和螺母的螺纹连接的夹紧力在使用过程中基本无变化;因此达到最好的锁紧效果,能有效避免螺杆与母体的螺纹孔螺纹连接失效。
在止转套上仅设有一个止转通孔,止转套的适用范围广,不受母体和附体上用来安装螺杆的孔的孔距限制。
在止转套上设有两个以上的止转通孔,在安装完两个以上螺杆后,止转套不会旋转,因此不再需要通过第一止转件上的第一止转孔或在附体上成型第一止转孔来约束止转套旋转,省去了第一止转件或在附体上成型第一止转孔的工序,降低了成本,且拆卸方便,拆卸时不会破坏止转套和附体。这种结构的紧固连接组件,所有构件均可重复拆卸,从而使附体相对母体是可拆卸,且能有效确保螺杆不转动,达到防止螺杆松动的目的。
通过第一止转孔的第四止转部与止转套的第三止转部配合约束止转套相对附体旋转,止转套的结构更紧凑,更符合通用的标准件紧固件的安装和使用习惯。
本发明的紧固连接结构,对于锁紧螺母与第一止转部的位置关系没有确定的情况下,螺杆与第四止转部的位置关系没有确定的情况,一般必须在螺杆的止转抵挡部的外周设有至少六个以上 的第一止转部,在止转套的止转通孔上设有六个以上的第二止转部,与一个第一止转与一个以上的第二止转部配合;和/或在止转套的外周设有至少六个以上的第三止转部,在第一止转孔上设有六个以上的第四止转部,一个第三止转部与一个以上的第四止转部配合,这样才能保证螺纹连接连接的预紧力。不用第一止转孔来约束止转套旋转,紧固连接结构的结构简单,成本低,但对这种结构,必须在螺杆的止转抵挡部的外周设有至少六个以上的第一止转部,在止转套的止转通孔上设有与一个第一止转部配合一个以上的第二止转部,这样才能保螺纹连接的预紧力。
取出止转套时,只需用夹持工具伸入夹持孔或夹持凹陷部内将止转套从设置在附体内的第一止转孔中取出或从第一止转件内的第一止转孔中取出,这样,这样即使止转套完全容置在附体内的第一止转孔中或止转件内的第一止转孔中,也能很方便取出。在止转套壁厚较薄、没有足够的空间设置夹持孔的情况下,设计成夹持凹陷部结构,在保证止转套刚性和强度的情况下,还能使夹持凹陷部的孔径满足夹持需要。
采用第一止转件的结构形式,不需在附体上加工第一止转孔。安装时,先安装螺杆,螺杆将母体和附体固定在一起,再依次安装止转套、止转件、止转套限位件,对于只有一个第一止转孔的止转件,最后在将第一止转件与附体用点焊等方法固定在一起,防止止转件旋转。这种结构的优点是一方面不需在附体上加工第一止转孔,大大降低加工成本低;另一方面在第一止转件上仅设有一个与止转套外周配合的第一止转孔的情况下,,止转件可以做成标准件,安装止转套和止转件时,不需调节螺杆的角度,使螺杆达到最佳的锁紧效果,且安装方便。仅设有一个第一止转孔的止转件适用范围广,具有通用性,不受母体和附体上的孔与孔之间的距离限制。这种结构的紧固连接组件,即使第一止转件通过点焊方式固定在附体上,螺杆、止转套、限位件安装部均可重复拆卸。
所述的螺杆的止转抵挡部的外周为正多边形,螺杆可以采用现有的标准件外六角螺栓,降低成本。螺杆的止转抵挡部与止转套的配合结构为花键形结构或正多边形结构或齿轮形结构、和/或止转套与第一止转孔配合的结构为花键形结构或正多边形结构或齿轮形结构,在满足加工和使用的前提下,成型越多个相互配合第一止转部和第二止转部、和/或相互配合的第三止转部和第四止转部,这样在螺杆与母体的螺纹连接处于最佳锁紧的状态下,为了安装止转套,微调螺杆时的角度越小,就能使螺杆的第一止转部与第一止转孔的第四止转部位置关系对应,满足止转套安装需要。微调螺杆的角度越小,螺杆与母体间的螺纹锁紧效果越好,避免螺杆和母体间的螺纹锁紧力过大或过小。
将第一止转件安装在止转件容置孔内,止转件外止转部与容置孔内止转部配合约束第一止转件相对附体旋转,通过止转套限位件或固定胶将止转套轴向限位在螺杆的第一止转部外和第一止转孔内,将第一止转件轴向限位在止转套外和止转件容置孔内,这样不需要将第一止转件通过焊接等方式不可转动地固定在附体上;止转件外止转部的个数少于第四止转部的个数,第一止转件的外周可为较大圆弧过渡的四边形,或带有止转平面的圆弧形等,止转件容置孔的形状与第一止转件外周的形状配合,这样止转件容置孔就可以直接铣削加工出来。由于需要在第一止转孔的孔壁上成型多个第一止转部,第一止转孔孔壁的形状为内齿轮形孔、或正多边形孔、或为两个以上结构相同的正多边形孔的相交结构,无法在附体上直接铣削加工出第一止转孔。增加了第一止转件,能在附体上直接铣削加工出止转件容置孔,对于机械零件紧固发挥止转功能的意义很大,第一止转件可以标准化大批量生产,综合成本低。
采用止转套限位件,一是止转套限位件拆卸方便,因此紧固连接组件与母体和附体的拆卸更方便;二是止转套限位件可重复使用;三是在高温、剧烈震动、对止转套需较大的轴向限位力等情况下,止转套限位件限位更可靠。止转套限位件安装部直接设置在螺杆上,止转套限位件安装部易加工,加工成本低。采用胶水将止转套固定在第一止转孔内,而不是通过止转套限位件将止转套固定在第一止转孔内,省去了止转套限位件,也不需要在螺杆或附体上加工安装止转套限位件的安装部,使紧固连接组件、紧固连接结构更简单,大大降低成本。 卡环安装在附体的卡槽内或扣盖的弹性卡扣扣在附体的卡槽内对止转套侧轴向限位,这种结构紧固连接结构,紧固连接组件全部隐藏在母体和附体内,外观美观,或满足紧固连接组件不可露出附体的情况。用止转套限位板对多个止转套限位,结构简单。
止转套限位件为抵挡螺母,螺杆可采用通用的标准件带止转结构的双头螺栓如标准件六角头双头螺栓,抵挡螺母也可采用通用的标准件螺母,这样抵挡螺母、螺杆和通用的标准件螺杆和螺母的成型方法相同,成型工艺成熟,且成型后不需再加工,成本低,抵挡螺母与螺杆螺纹连接安装也方便。抵挡螺母与螺杆虽然也是螺纹连接,但抵挡螺母并不承受来自连接母体和附体的力,受力很小,因此抵挡螺母与螺杆的螺纹连接几乎不可能失效。
止转套限位件为扣盖,扣盖不但能对止转套轴向限位,还有盖子的作用,使止转套和螺杆不会暴露在空气中,从而大大增加止转套和螺杆的使用寿命,使用更安全,外观更美观,扣盖还可起装饰作用。止转套限位件为卡环或扣盖,在螺纹容易失效的场合,卡环轴向限位更可靠。
止转套限位件为抵挡螺钉,一方面成本低,另一方面抵挡螺钉不但能对止转套轴向限位,还有盖子的作用,使止转套和螺杆不会暴露在空气中,从而大大增加止转套、螺杆的使用寿命,使用更安全,外观更美观。
第一止转件上的所述的第一止转孔与附体上的通孔一一对应的,第一止转件的形状与附体上的通孔的排列形状配合,这种结构的紧固连接结构,特别适用于箱体零件的紧固止转,比如变速箱等。
螺杆的第一外螺纹部与锁紧螺母螺纹连接,而不是与母体螺纹连接,对于材质硬度低的母体如木材、铸铁、铝材灯,这种螺纹连接更可靠,不容易滑丝。螺杆的第一外螺纹部与锁紧螺母不可转动地连接在一起,防止螺杆和锁紧螺母间反转松脱,螺杆与锁紧螺母的连接非常可靠。
由于第二止转孔与锁紧螺母配合,当锁紧螺母上有多个止转部时,如锁紧螺母为正六角形、外齿轮形、或花键形等,第二止转孔的形状也为相应的正六角形孔、内齿轮形孔孔、或花键形孔等,这种结构的第二止转孔无法直接铣削出来,加工这种结构的第二止转孔的成本会比较高。采用第二止转件的结构形式,不需在附体上加工第二止转孔,特别适合附体太薄无法加工螺纹孔、或附体材质硬度低如铝、、铸铁等等不适合加工螺纹孔等情况。对于仅设有一个第二止转孔的第二止转件,安装时,可先将螺杆穿过母体和附体上的通孔与锁紧螺母螺纹连接,再安装止转套、止转套限位件,再将第二止转件通过点焊方式固定在附体上,优点是这种结构的第二止转件适用范围广,具有通用性,不受母体和附体上的孔与孔之间的距离限制;即使第二止转件通过点焊方式固定在附体上,螺杆、锁紧螺母、止转套、限位件安装部均可重复拆卸,从而使附体相对母体是可拆卸,且能有效确保螺杆、锁紧螺母不转动,达到防止螺杆和锁紧螺母松动的目的,特别是安装第二止转件时,不需调节锁紧螺母的角度,使锁紧螺母和螺杆达到最佳的锁紧效果,且安装方便。对于设有两个以上的第二止转孔的第二止转件,在安装两个以上螺杆后,第二止转件不需与母体固定也不会旋转,第二止转件拆卸方便,拆卸时不会破坏第二止转件和附体。这种结构的紧固连接组件,第二止转件可重复拆卸。采用止转件限位件对第二止转件轴向限位,方便第二止转件与母体拆离。采用锁紧螺母的止转件抵挡部对第二止转件轴向限位,相对于采用止转件限位件轴向限位第二止转件,结构较简单。
对于用螺杆连接连杆大头盖和连杆体的,由于限制了螺杆的转动,因此即使连杆体承受很大地力、或曲轴连杆处于剧烈震动的环境,螺杆也不会反转而松脱导致螺杆与连杆体上的螺纹孔螺纹连接失效,螺杆将连杆体和连杆大头盖非常可靠地固定在一起,这样确保连杆体和连杆大头盖可靠地安装在一起,防止事故发生。
对于用螺杆和锁紧螺母连接连杆大头盖和连杆体的,由于限制了螺杆和锁紧螺母的转动,螺杆和锁紧螺母就不会反转而松脱导致螺杆与锁紧螺母螺纹连接失效,螺杆和锁紧螺母将连 杆体和连杆大头盖同样非常可靠地固定在一起。不是在连杆体上成型螺纹孔,而是增加锁紧螺母,且锁紧螺母不可转动地与连杆体安装在一起,一方面不需在连杆体上攻螺纹孔,另一方面对连杆体的材质的硬度没有限制。
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,由于止转套约束螺杆不会旋转,止转套相对弹条不会旋转,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,螺纹连接也很可靠,不会因为螺杆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。
采用本发明的紧固连接组件的轨道结构,通过紧固连接组件将垫板固定在地基的预埋套管内,由于止转套约束螺杆不会旋转,止转套相对垫板不会旋转,因此即使轨道结构处于剧烈震动的环境,螺纹连接也很可靠,不会因为螺杆反转松脱导致螺纹连接失效,这样确保垫板可靠地与地基的预埋套管安装在一起,防止事故发生。
采用膨胀结构的紧固连接结构,这种结构特别适用与母体上的孔是盲孔、螺杆无法穿过母体的情况,和在母体上无法攻螺纹的金属材质等,还有就是母体的材质比较软、采用螺纹连接容易滑丝、如母体为铝材质等。膨胀紧固连接组件还包括驱动螺母,安装时先将螺杆通过膨胀套的结构安装在母体上,再安装附体,便于将螺杆安装在母体上。在膨胀套上设有膨胀套抵挡部,在母体的孔壁上设有抵挡槽,膨胀套抵挡部伸入预埋套管的抵挡槽内通过面与面相互抵挡形成卡合,这样膨胀套与母体的连接力主要是抵挡部与抵挡槽间的相互抵挡力,而不是依靠螺纹连接的预紧静摩擦力或膨胀螺丝的胀紧静摩擦力。膨胀件上的抵挡部可为一个抵挡部。膨胀件上的抵挡部也可为多个抵挡部,单个抵挡部在经过轴线的截面上的形状为尖角形或梯形或弧形;母体上的抵挡槽在经过轴线的截面上的形状为与抵挡部配合的尖角形或梯形或弧形;抵挡部与抵挡槽通过尖角形两个斜面面接触或梯形的两个斜面面接触、或通过弧形面接触。这种膨胀紧固连接结构可以承受的连接力非常大。因此能在载荷大特别是轴向载荷大、振动大、高温等环境下均不会引起连接失效。对应采用膨胀结构的紧固连接结构,安装在螺杆的止转抵挡部外的止转套及对止转套止转的第一止转孔的结构、对止转套限位的结构与不是膨胀结构的紧固连接组件相同,故不再重复描述。
采用连接件连接两个断骨,由于止转套约束螺杆不会旋转,连接件上的第一止转孔约束止转套不会旋转,因此连接件连接两断骨非常可靠。
