技术领域
[0001] 本发明属于设备通用技术领域， 尤其是涉及一种哑铃状锥度左小右大双向锥形 外螺纹与传统螺纹连接结构即类哑铃状 （左侧锥度小于右侧锥度） 非对称双向 锥形螺纹外螺纹与传统螺纹的连接结构 （以下简称“双向锥形外螺纹与传统螺纹” 背景技术
[0002] 螺纹的发明， 对人类社会进步产生深刻影响。 螺纹是最基础工业技术之一， 她 不是具体产品， 是产业关键共性技术， 其技术性能必须要有具体产品作为应用 载体来体现， 各行各业应用广泛。 5见有螺纹技术， 标准化水平高， 技术理论成 熟， 实践应用久远， 用之紧固， 则是紧固螺纹； 用之密封， 则为密封螺纹； 用 之传动， 则成传动螺纹。 根据国家标准的螺纹术语： “螺纹”是指在圆柱或圆锥表 面上， 具有相同牙型、 沿螺旋线连续凸起的牙体； “牙体”是指相邻牙侧间的材料 实体。 这也是全球共识的螺纹定义。
[0003] 现代螺纹始于 1841年英国惠氏螺纹。 按照现代螺纹技术理论， 螺纹自锁基本条 件是： 当量摩擦角不得小于螺旋升角。 这是现代螺纹基于其技术原理—“斜面 原理”对螺纹技术的一种认识， 成为现代螺纹技术的重要理论依据。 最早对斜面 原理进行理论解释的是斯蒂文， 他研究发现斜面上物体平衡的条件与力合成的 平行四边形定律， 1586年他提出了著名的斜面定律： 放在斜面上的一个物体所 受的沿斜面方向的重力与倾角的正弦成正比。 所述的斜面， 是指与水平面成倾 斜的光滑平面， 螺旋是“斜面”的变形， 螺纹就像包裹在圆柱体外的斜面， 斜面越 平缓， 机械利益越大 （见图 A） （杨静珊、 王绣雅， 《螺丝钉的原理探讨》 ， 《 高斯算术研究》 ） 。
[0004] 现代螺纹的“斜面原理”， 是基于斜面定律建立起来的斜面滑块模型 （见图 B）
， 人们认为， 在静载荷和温度变化不大条件下， 当螺纹升角小于等于当量摩擦 角， 螺纹副具备自锁条件。 螺纹升角 （见图三 C） 又称为螺纹导程角， 就是在中 径圆柱上螺旋线的切线与垂直于螺纹轴线的平面间的夹角， 该角度影响螺纹自 锁和防松。 当量摩擦角就是把不同的摩擦形式最终转化成最普通的斜面滑块形 式时对应的摩擦角。 通俗讲， 在斜面滑块模型中， 当斜面倾斜到一定角度， 滑 块此时的摩擦力恰好等于重力沿着斜面的分量， 此时物体刚好处于受力平衡状 态， 此时的斜面倾斜角称为当量摩擦角。
[0005] 美国工程师于上世纪中叶发明了楔形螺纹， 其技术原理仍旧遵循“斜面原理”。
楔形螺纹的发明， 受到“木楔子”启发。 具体说， 楔形螺纹的结构是在三角形螺纹 （俗称普通螺纹） 内螺纹 （即螺母螺纹） 的牙底处有一个与螺纹轴线成 25°〜 30° 夹角的楔形斜面， 工程实际都取 30°楔形斜面。 一直以来， 人们都是从螺纹牙型 角这个技术层面和技术方向去研究和解决螺纹防松脱等问题， 楔形螺纹技术也 不例外， 是斜楔技术的具体运用。
[0006] 但是， 5见有螺纹存在连接强度低、 自定位能力弱、 自锁性差、 承力值小、 稳定 性差、 兼容性差、 重复使用性差、 高温低温等问题， 典型的是应用现代螺纹技 术的螺栓或螺母普遍存在着容易松动缺陷， 随着设备频繁振动或震动， 引起螺 栓与螺母松动甚至脱落， 严重的容易发生安全事故。

[0007] 任何技术理论， 都有理论假设背景， 螺纹也不例外。 随着科技进步， 对连接破 坏已非单纯线性载荷更非静态更非室温环境， 存在线性载荷非线性载荷甚至是 二者叠加并由此产生更复杂破坏载荷情况， 应用工况复杂， 基于这样认识， 本 发明的目的是针对上述问题， 提供一种设计合理、 结构简单， 具有良好连接性 育 B、 锁紧性能的双向锥形外螺纹与传统螺纹的连接结构。
[0008] 为达到上述目的， 本发明采用了下列技术方案： 本双向锥形外螺纹与传统螺纹 的连接结构， 是由非对称双向锥形螺纹外螺纹与传统螺纹内螺纹组成螺纹连接 副使用， 是一种特殊的合成了圆锥副与螺旋运动技术特点的螺纹副技术， 所述 的双向锥形螺纹外螺纹， 是一种合成了双向锥形体与螺旋结构技术特点的螺纹 技术， 所述的双向锥形体是由两个单锥形体组成， 是由左侧与右侧锥度的方向 相向且左侧锥形体锥度小于右侧锥形体锥度两个单锥形体双向组成， 上述的非 对称双向锥形螺纹外螺纹是由双向锥形体呈螺旋状分布于柱状母体的外表面形 成外螺纹， 其完整单元体螺纹是一种中间小两端大且左侧锥度小于右侧锥度的 呈类哑铃状特殊双向锥形几何体。
[0009] 本双向锥形外螺纹与传统螺纹， 所述的类哑铃状非对称双向锥形螺纹外螺纹定 义， 可以表达为： “在圆柱或圆锥外表面上， 具有规定左侧锥度和右侧锥度且左 侧锥度与右侧锥度的方向相向且左侧锥度小于右侧锥度的非对称双向圆锥台体 、 沿着螺旋线连续和 /或不连续分布的呈螺旋状且呈中间小两端大的呈类哑铃状 特殊双向锥形几何体。 ”因制造等方面原因， 非对称双向锥形螺纹的螺头、 螺尾 可能是不完整的双向锥形几何体。 与现代螺纹技术不同， 螺纹技术已由原先现 代螺纹内螺纹外螺纹啮合关系转变为本双向锥形螺纹内螺纹外螺纹抱合关系。
[0010] 本双向锥形外螺纹与传统螺纹， 包括相互螺纹配合的外螺纹与内螺纹， 外螺纹 是呈螺旋状分布于柱状母体外表面的双向圆锥台体， 内螺纹是呈螺旋状分布于 筒状母体内表面的特殊锥形孔， 即内螺纹以呈螺旋状特殊锥形孔并以“非实体空 间”形态存在、 夕卜螺纹以呈螺旋状双向圆锥台体并以“材料实体”形态存在， 所述 的非实体空间是指能够容纳上述材料实体的空间环境， 内螺纹是包容件， 外螺 纹是被包容件： 内螺纹与外螺纹是一节一节双向锥形几何体旋合套接在一起抱 合直至一侧双向承载或左侧右侧同时双向承载或直至定径过盈配合， 两侧是否 同时双向承载与应用实际工况有关， 即传统内螺纹缘于与双向锥形螺纹外螺纹 的接触而形成的特殊锥形孔一节一节包容抱合双向锥形螺纹外螺纹的双向圆锥 台体， 即内螺纹是一节一节抱合对应外螺纹。
[0011] 所述的螺纹连接副是由呈螺旋状的外锥面与呈螺旋状的内锥面相互配合构成圆 锥副形成螺纹副， 所述的双向锥形螺纹外圆锥体的外锥面为双向圆锥面， 当所 述的双向锥形外螺纹与传统内螺纹组成螺纹连接副， 是以传统内螺纹特殊圆锥 面与双向锥形外螺纹外圆锥面的结合面为支承面， 即以圆锥面为支承面， 实现 连接技术性能， 螺纹副自锁性、 自定位性、 重复使用性和抗疲劳性等能力主要 取决于构成本双向锥形外螺纹与传统螺纹的双向锥形外螺纹圆锥台体圆锥面及 其锥度大小以及传统螺纹内螺纹缘于与双向锥形外螺纹接触而形成的特殊锥形 孔特殊圆锥面及锥度， 是一种非牙型螺纹。
[0012] 与现有螺纹斜面原理所表现的分布于斜面上的单向力以及内、 外螺纹是内牙体 与外牙体的啮合关系不同， 本双向锥形外螺纹与传统螺纹， 外螺纹体即双向锥 形体无论分布于左侧或右侧任何一侧单锥形体通过圆锥轴线截面是由圆锥体两 条素线双向组成即呈双向状态， 所述的素线是圆锥表面与通过圆锥轴线的平面 的交线， 本双向锥形外螺纹与传统螺纹的连接结构的圆锥原理所表现的是轴心 力与反轴心力， 二者均是由双向力合成， 轴心力与对应的反轴心力对顶， 内螺 纹与外螺纹是抱合关系， 即组成螺纹副是通过内螺纹抱住外螺纹即一节节锥孔 （内圆锥体） 抱合对应的一节节锥体 （外圆锥体） 直至抱合定径配合实现自定 位或直至定径过盈接触实现自锁， 即通过特殊锥形孔与圆锥台体径向抱合在一 起实现内圆锥体与外圆锥体自锁紧或自定位进而实现螺纹副的自锁紧或自定位 ， 而非传统螺纹内螺纹与外螺纹组成螺纹连接副是通过彼此牙体与牙体相互抵 靠实现螺纹连接性能。
[0013] 内螺纹与外螺纹的抱合过程达到一定条件会有一种自锁力， 所述的自锁力是由 内圆锥轴心力与外圆锥反轴心力之间所产生压强生成， 即当内圆锥与外圆锥组 成圆锥副， 内圆锥体的内圆锥面抱合外圆锥体的外圆锥面， 内圆锥面与外圆锥 面紧密接触。 所述的内圆锥轴心力与外圆锥反轴心力是本发明双向锥形螺纹技 术即圆锥副技术所独有的力的概念。
[0014] 内圆锥体以类似轴套的形态存在， 在外来载荷作用下， 内圆锥体生成指向或者 说压向圆锥轴线的轴心力， 所述的轴心力是由一对以圆锥轴线为中心呈镜像分 布且分别垂直于圆锥体两条素线的向心力双向合成， 即轴心力通过圆锥轴线截 面是由以圆锥轴线为中心呈镜像双向分布于圆锥轴线两侧且分别垂直于圆锥体 两条素线且指向或者说压向圆锥轴线共同点的两条向心力组成且当上述的圆锥 体与螺旋结构合成为螺纹并应用于螺纹副则上述的轴心力通过螺纹轴线截面是 由以螺纹轴线为中心呈镜像和 /或近似镜像双向分布于螺纹轴线两侧且分别垂直 于圆锥体两条素线且指向或者说压向螺纹轴线共同点和 /或近似共同点的两条向 心力组成， 所述的轴心力是以轴向并周向的方式密密麻麻地分布于圆锥轴线和 / 或螺纹轴线， 所述的轴心力对应的有一个轴心力角， 组成所述的轴心力的两条 向心力的夹角构成上述的轴心力角， 所述的轴心力角大小取决于圆锥体的锥度 大小即锥角大小。
[0015] 外圆锥体以类似轴的形态存在， 具备较强吸收外来各种载荷能力， 外圆锥体生 成与内圆锥体每一轴心力对顶的反轴心力， 所述的反轴心力是由一对以圆锥轴 线为中心呈镜像分布且分别垂直于圆锥体两条素线的反向心力双向合成， 即反 轴心力通过圆锥轴线截面是由以圆锥轴线为中心呈镜像双向分布于圆锥轴线两 侧且分别垂直于圆锥体两条素线且由圆锥轴线共同点指向或者说压向内圆锥面 的两条反向心力组成且当上述的圆锥体与螺旋结构合成为螺纹并应用于螺纹副 则上述的反轴心力通过螺纹轴线截面是由以螺纹轴线为中心呈镜像和 /或近似镜 像双向分布于螺纹轴线两侧且分别垂直于圆锥体两条素线且由螺纹轴线共同点 和 /或近似共同点指向或者说压向内螺纹圆锥面的两条反向心力组成， 所述的反 轴心力是以轴向并周向的方式密密麻麻地分布于圆锥轴线和 /或螺纹轴线， 所述 的反轴心力对应的有一个反轴心力角， 组成所述的反轴心力的两条反向心力的 夹角构成上述的反轴心力角， 所述的反轴心力角大小取决于圆锥体的锥度大小 即锥角大小。
[0016] 轴心力与反轴心力在圆锥副的内外圆锥有效接触时开始生成， 即圆锥副的内圆 锥体与外圆锥体的有效接触过程始终存在一对对应且相对顶的轴心力与反轴心 力， 所述的轴心力与反轴心力均是以圆锥轴线和 /或螺纹轴线为中心且呈镜像双 向分布的双向力而非单向力， 所述的圆锥轴线与螺纹轴线是重合轴线即是同一 轴线和 /或近似同一轴线， 反轴心力与轴心力是反向共线且当上述的圆锥体与螺 旋结构合成为螺纹并组成螺纹副是反向共线和 /或近似反向共线， 通过内圆锥与 外圆锥的抱合直至过盈则轴心力与反轴心力由此在内圆锥面与外圆锥面的接触 面生成压强并密密麻麻地轴向并周向均匀分布在内外圆锥表面的接触面， 当内 圆锥与外圆锥的抱合运动一直进行直至圆锥副达到过盈配合所生成压强将内圆 锥与外圆锥结合在一起， 即上述的压强已能做到内圆锥体抱合外圆锥体形成类 似整体构造体并在其促成的外力消失后并不会因为上述的类似整体构造体体位 的方向任意变化而在重力作用下导致内外圆锥体相互脱离， 圆锥副产生自锁紧 即螺纹副产生自锁紧， 这种自锁紧性对于除了重力之外的可能导致内外圆锥体 彼此相互脱离的其他外来载荷也有一定限度的抵抗作用， 圆锥副还具有内圆锥 与外圆锥相互配合的自定位性， 但并非任意轴心力角和 /或反轴心力角都能让圆 锥副产生自锁紧和自定位。
[0017] 当轴心力角和 /或反轴心力角小于 180°且大于 127°， 圆锥副具备自锁性， 轴心力 角和 /或反轴心力角无限接近于 180°时， 圆锥副的自锁性最佳， 其轴向承载能力 最弱， 轴心力角和 /或反轴心力角等于和或小于 127°且大于 0°， 则圆锥副处于自 锁性弱和 /或不具自锁性区间， 轴心力角和 /或反轴心力角趋向于向无限接近于 0° 方向变化， 则圆锥副的自锁性呈衰减趋势方向变化直至完全不具自锁紧能力， 轴向承载能力呈增强趋势方向变化直至轴向承载能力最强。
[0018] 当轴心力角和 /或反轴心力角小于 180°且大于 127°， 圆锥副处于强自定位状态， 容易达到内外圆锥体强自定位， 轴心力角和 /或反轴心力角无限接近于 180°时， 圆锥副的内外圆锥体自定位能力最强， 轴心力角和 /或反轴心力角等于和或小于 1 27°且大于 0°， 圆锥副处于弱自定位状态， 轴心力角和 /或反轴心力角趋向于向无 限接近于 0°方向变化， 则圆锥副的内外圆锥体相互自定位能力呈衰减趋势方向变 化直至接近完全不具自定位能力。
[0019] 本双向锥形螺纹连接副， 较之申请人此前发明的单锥形体的单向锥形螺纹只能 圆锥面单侧承载的不可逆性单侧双向包容的包容与被包容关系， 双锥形体的双 向锥形螺纹的可逆性左右两侧双向包容， 可以做到圆锥面左侧承载和 /或圆锥面 右侧承载和 /或左侧圆锥面右侧圆锥面分别承载和 /或左侧圆锥面右侧圆锥面双向 同时承载， 更限制特殊锥形孔与圆锥台体之间的无序自由度， 螺旋运动又让双 向锥形外螺纹与传统螺纹连接结构获取了必须的有序自由度， 有效合成了圆锥 副与螺纹副技术特点形成全新螺纹技术。
[0020] 本双向锥形外螺纹与传统螺纹的连接结构在使用时双向锥形螺纹外螺纹的双向 圆锥台体圆锥面与传统内螺纹的特殊锥形孔特殊圆锥面相互配合。
[0021] 本双向锥形外螺纹与传统螺纹， 双向锥形外螺纹即圆锥台体并非任意锥度或者 说任意锥角均可实现螺纹连接副的自锁紧和 /或自定位， 外圆锥体必须达到一定 锥度或者说一定锥角， 双向锥形外螺纹与传统螺纹连接结构才具备自锁性和自 定位性， 所述的锥度包括外螺纹体的左侧锥度和右侧锥度， 所述的锥角包括外 螺纹体的左侧锥角和右侧锥角， 所述的左侧锥度对应左侧锥角即第一锥角 ocl， 优选地， 0° <第一锥角011 < 53°， 优选地， 第一锥角 al取值为 2°〜 40° ; 所述的右 侧锥度对应右侧锥角即第二锥角 oc2, 优选地， 0° <第二锥角012 < 53°， 优选地， 第二锥角 al取值为 2°〜 40°， 个别特殊领域， 优选地， 53%第二锥角 a2 < 180°， 优选地， 第二锥角 a2取值为 53°〜 90°。
[0022] 上述的个别特殊领域， 是指自锁性要求低甚至不需要自锁性和 /或自定位性要 求弱和 /或轴向承载力要求高和 /或必须设置防抱死措施的传动连接等等螺纹连接 应用领域。

[0024] 本双向锥形外螺纹与传统螺纹， 所述的双向圆锥台体即外螺纹， 其特征是， 是 由具有下底面相同且上顶面相同但锥高不同的两个圆锥台体的上顶面对称并相 向相互接合呈螺旋状而成螺纹且下底面处于双向圆锥台体的两端且形成类哑铃 状非对称双向锥形螺纹时包括分别与相邻双向圆锥台体的下底面相互接合和 /或 或将分别与相邻双向圆锥台体的下底面相互接合呈螺旋状而成螺纹， 所述的外 螺纹包括圆锥台体第一螺旋状圆锥面和圆锥台体第二螺旋状圆锥面和外螺旋线 ， 在通过螺纹轴线的截面内， 其完整单节非对称双向锥形外螺纹是中间小两端 大且左侧锥度小于右侧锥度的呈类哑铃状特殊双向锥形几何体， 所述的双向圆 锥台体包括双向圆锥台体圆锥面， 其左侧圆锥面即圆锥台体第一螺旋状圆锥面 两条素线间的夹角为第一锥角 ocl， 圆锥台体第一螺旋状圆锥面形成左侧锥度且 呈右向分布， 其右侧圆锥面即圆锥台体第二螺旋状圆锥面两条素线间的夹角为 第二锥角 oc2, 圆锥台体第二螺旋状圆锥面形成右侧锥度且呈左向分布， 所述的 第一锥角 od与第二锥角 a2所对应锥度方向相向， 所述的素线是圆锥表面与通过 圆锥轴线的平面的交线， 所述的双向圆锥台体的圆锥台体第一螺旋状圆锥面和 圆锥台体第二螺旋状圆锥面形成的形状与以重合于柱状母体中轴线具有下底边 相同且上底边相同但直角边不同的两个直角梯形的上底边对称并相向接合的直 角梯形结合体的直角边为回转中心周向匀速回转且该直角梯形结合体同时沿柱 状母体中轴线匀速轴向移动而由直角梯形结合体两条斜边形成的回旋体的螺旋 外侧面形状相同， 所述的直角梯形结合体是指具有下底边相同且上底边相同但 直角边不同的两个直角梯形的上底边对称并相向接合且下底边分别处于直角梯 形结合体两端的特殊几何体。
[0025] 所述的双向锥形外螺纹因其螺纹体是锥形体即圆锥台体这一独特技术特点和优 势， 具有较强同化异种螺纹能力， 即具有能够将与之相配合的传统螺纹同化变 成与自己具有相同技术特点和性质的特殊形式锥形螺纹的能力， 被锥形螺纹同 化后的传统螺纹， 即异化传统螺纹， 看上去其螺纹体外形与传统螺纹牙体没有 多大区别， 但已不具传统螺纹之螺纹体实质性技术内容， 其螺纹体由原来传统 螺纹牙体性质变成具有锥形螺纹的螺纹体性质即锥形体性质和技术特点的特殊 锥形几何体， 特殊锥形几何体径向有能与锥形螺纹螺旋状圆锥面相匹配的特殊 圆锥面， 上述的传统螺纹包括三角形螺纹、 梯形螺纹、 锯齿形螺纹、 矩形螺纹 、 圆弧螺纹等可以与上述的双向锥形螺纹拧合组成螺纹连接副的其他几何形态 螺纹， 但不局限于上述几种。
[0026] 当传统内螺纹与双向锥形外螺纹配合组成螺纹连接副， 此时的传统内螺纹已非 本来意义上的传统螺纹， 而是一种被锥形螺纹所同化了的特殊形式的锥形螺纹 ， 其与双向锥形外螺纹接触部分形成所述的螺纹连接副的传统内螺纹的特殊锥 形孔的能与锥形螺纹螺旋状圆锥面相匹配的内表面， 即特殊锥形孔上有特殊圆 锥面， 随着拧合使用次数的增加， 传统内螺纹的特殊锥形孔上的特殊圆锥面有 效圆锥面面积会不断增加即特殊圆锥面会不断加大并趋向于与双向锥形外螺纹 圆锥台体圆锥面有更大接触面方向变化， 实质上形成一种虽然锥形几何形状不 完整但已具备本发明技术精神的特殊锥形孔， 进一步地说， 所述的特殊锥形孔 是传统内螺纹缘于与双向锥形外螺纹抱合性接触而被其所同化形成的螺纹体， 是由传统内螺纹牙体转变而来的特殊锥形几何体， 所述的特殊锥形孔径向有能 与双向圆锥台体圆锥面相匹配的内表面即特殊圆锥面， 即所述的螺纹连接副是 由呈螺旋状的外锥面即双向锥形外螺纹的外圆锥面与呈螺旋状的特殊内锥面即 传统内螺纹缘于与双向锥形外螺纹接触而构成的特殊锥形孔特殊圆锥面相互配 合构成圆锥副形成螺纹副， 外圆锥面即外圆锥体即圆锥台体的外锥面为双向圆 锥面， 被其同化后的传统螺纹， 是一种异化传统螺纹， 是一种特殊形式锥形螺 纹， 这种特殊形式锥形螺纹内圆锥面即传统内螺纹的特殊圆锥面先以线的形态 出现， 并随着传统内螺纹牙尖与双向锥形外螺纹圆锥台体接触使用次数增加而 内锥面逐渐增加， 即传统内螺纹的特殊圆锥面是由微观上的面 （宏观上是线） 到宏观上的面不断变化加大， 也可以直接在传统内螺纹的牙尖部位加工出与双 向锥形外螺纹相匹配的内锥面， 这些都符合本发明技术精神。
