Description

类哑铃状与类橄榄状非对称双向锥形螺纹连接副 技术领域
本发明属于设备通用技术领域，尤其是涉及一种类哑铃状与类橄榄状非对称双向锥形螺纹连接副(以下简称“双向锥形螺纹连接副”)。
背景技术
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。现有螺纹技术，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。
[根据细则91更正 29.05.2019]　
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7即图A)(杨静珊、王绣雅，《螺丝钉的原理探讨》，《高斯算术研究》)。
[根据细则91更正 29.05.2019]　
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8即图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9即图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。
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。
现代螺纹的种类和形式较多，均为牙型螺纹，这是由其技术原理即斜面原理所决定的。具体地，在圆柱表面形成的螺纹称为圆柱螺纹，在圆锥表面形成的螺纹称为圆锥螺纹，在圆柱或圆锥台体等端面表面形成的螺纹称为平面螺纹；在母体外圆表面形成的螺纹称为外螺纹，在母体内圆孔表面形成的螺纹称为内螺纹，在母体端面表面形成的螺纹称为端面螺纹；旋向与螺纹升角方向符合左手定则的螺纹称为左旋螺纹，旋向与螺纹升角方向符合右手定则的螺纹称为右旋螺纹；在母体同一截面内只有一条螺旋线的螺纹称为单线螺纹，有两条螺旋线的螺纹称为双线螺纹，有多条螺旋线的螺纹称为多线螺纹。截面形状为三角形的螺纹称为三角形螺纹，截面形状为梯形的螺纹称为梯形螺纹，截面形状为矩形的螺纹称为矩形螺纹，截面形状为锯齿形的螺纹称为锯齿形螺纹。
但是，现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。

问题的解决方案
技术解决方案
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，具有良好连接性能、锁紧性能的类哑铃状与类橄榄状非对称双向锥形螺纹连接副。
为达到上述目的，本发明采用了下列技术方案：本类哑铃状与类橄榄状非对称双向锥形螺纹连接副，是由非对称双向锥形外螺纹与非对称双向锥形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，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，两个单锥形体分别位于双向锥形体左右两侧，即是由左侧锥度与右侧锥度的方向相反和/或相向且锥度不同的两个单锥形体双向组成，所述的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和/或上述的双向锥形体呈螺旋状分布于筒状母体的内表面形成内螺纹，其完整单元体螺纹是一种双向锥形几何构造，包括类橄榄状和类哑铃状两种特殊双向锥形几何体结构形式，即所述的双向锥形螺纹其完整单元体螺纹包括类橄榄状双向锥形螺纹和类哑铃状双向锥形螺纹。
本双向锥形螺纹连接副，所述的非对称双向锥形螺纹定义，可以表达为：“在圆柱或圆锥表面上，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反或相向且锥度不同的非对称双向锥形孔(或非对称双向圆锥台体)、沿着螺旋线连续(或不连续)分布的呈螺旋状的特殊双向锥形几何体，包括呈类橄榄状和呈类哑铃状两种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，完整单元体螺纹和/或不完整单元体螺纹的数量称谓上，双向锥形螺纹不再以“牙数”为单位，而是以“节数”为单位，即不再称几牙螺纹，而称几节螺纹。这种螺纹数量称谓上的变化，是基于技术内涵变化而发生，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双向锥形螺纹内螺纹外螺纹抱合关系。无论内螺纹外螺纹，双向锥形螺纹的完整单节螺纹有两种形式，一种是中间大且两端小的呈类橄榄状的特殊双向锥形几何体，一种是中间小且两端大的呈类哑铃状的特殊双向锥形几何体，两种形式的技术原理一样，只是结构形式不同。
本双向锥形螺纹连接副，包括呈螺旋状分布于柱状母体外表面的双向圆锥台体和呈螺旋状分布于筒状母体内表面的双向锥形孔，即包括相互螺纹配合的外螺纹与内螺纹，内螺纹分布的是呈螺旋状的双向锥形孔、外螺纹分布的是呈螺旋状的双向圆锥台体，内螺纹以呈螺旋状双向锥形孔(非实体空间)形态存在，外螺纹以呈螺旋状双向圆锥台体(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，螺纹的工作状态是：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，内螺纹外螺纹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领域实际工况有关，即双向锥形孔一节一节包容双向圆锥台体，即内螺纹是一节一节抱合对应外螺纹。
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与内圆锥体的内锥面均为双向圆锥面，当所述的双向锥形螺纹之间组成螺纹连接副，是以内圆锥面与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，螺纹副的自锁性、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非对称式双向锥形螺纹连接副圆锥副的圆锥面及其锥度大小即内螺纹外螺纹的圆锥面及其锥度大小，是一种非牙型螺纹。
与现有螺纹的斜面原理所表现的分布于斜面上的单向力以及内螺纹与外螺纹是内牙体与外牙体之间的啮合关系不同，本双向锥形螺纹连接副所述的双向锥形体中无论分布于左侧或右侧的任何一侧的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，本非对称式双向锥形螺纹连接副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，而非传统螺纹的内螺纹与外螺纹组成螺纹连接副是通过彼此牙体与牙体之间相互抵靠 实现螺纹连接性能，这是本发明螺纹技术内螺纹与外螺纹的一种工作关系状态。
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。
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。
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。
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。
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向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向方向变化直至轴向承载能力最强。
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127°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向方向变化直至接近完全不具自定位能力。
轴心力与反轴心力的关系，决定了双向锥形螺纹这样一种螺纹机械结构，内螺纹与外螺纹之间是包容与被包容关系，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，更限制锥形孔与圆锥台体之间的无序自由度，螺旋运动又让非对称双向锥形螺纹连接副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。
本双向锥形螺纹连接副在使用时双向锥形螺纹外螺纹的双向圆锥台体圆锥面与双向锥形螺纹内螺纹的双向锥形孔圆锥面相互配合。
本双向锥形螺纹连接副的双向锥形螺纹的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或自定位，内、外圆锥体即圆锥台体和/或锥形孔必须达到一定锥度，非对称双向锥形螺纹连接副才具备自锁性和自定位性，所述的锥度包括内、外螺纹体的左侧锥度和右侧锥度，组成本双向锥形螺纹连接副的双向锥形螺纹有两种形式，一种是双向锥形螺纹的左侧锥度大于右侧锥度，即右侧锥度小于左侧锥度，一种是双向锥形螺纹的左侧锥度小于右侧锥度，即右侧锥度大于左侧锥度。
本双向锥形螺纹连接副中，上述的左侧锥度对应左侧锥角即第一锥角α1、右侧锥度对应右侧锥角即第二锥角α2，上述的左侧锥度大于右侧锥度时，优选地，0°＜第一锥角α1＜53°，优选地，第一锥角α1取值为2°～40°，个别特殊领域，优选地，53°≤第一锥角α1＜180°，优选地，第一锥角α1取值为53°～90°；优选地，0°＜第二锥角α2＜53°，优选地，第二锥角α2取值为2°～40°。

具体应用时，本双向锥形螺纹连接副是由左侧锥度小于右侧锥度类橄榄状非对称双向锥形外螺纹与左侧锥度大于右侧锥度类哑铃状非对称双向锥形内螺纹组成螺纹副使用和/或是由左侧锥度大于右侧锥度类哑铃状非对称双向锥形外螺纹 与左侧锥度小于右侧锥度类橄榄状非对称双向锥形内螺纹组成螺纹副使用，作为螺纹工作支承面的相互配合螺旋状圆锥面会出现组合变化，包括锥形孔第一螺旋状圆锥面与圆锥台体第二螺旋状圆锥面接触面互为支承面和/或锥形孔第二螺旋状圆锥面与圆锥台体第一螺旋状圆锥面接触面互为支承面和/或左侧圆锥面右侧圆锥面同时承载，但不局限于以上相互配合螺旋状圆锥面的组合形式，但无论何种组合，其技术原理是一样的。
本双向锥形螺纹连接副传动连接时，通过双向锥形内螺纹双向锥形孔与双向锥形外螺纹双向圆锥台体的旋合连接，双向承载，当外螺纹与内螺纹组成螺纹副，内螺纹与外螺纹之间必须要有游隙，即双向锥形外螺纹双向圆锥台体与双向锥形内螺纹双向锥形孔之间必须要有游隙，内螺纹与外螺纹之间若有油类等介质润滑，将容易形成承载油膜，游隙有利于承载油膜形成，本非对称双向锥形螺纹连接副应用于传动连接相当于一组由一副和/或数副滑动轴承组成的滑动轴承副，即每一节双向锥形内螺纹双向包容相对应一节双向锥形外螺纹，构成一副滑动轴承，整个非对称双向锥形螺纹连接副应用于传动连接时，组成的滑动轴承数量根据应用工况进行相应调整，即双向锥形内螺纹与双向锥形外螺纹有效双向接合即有效双向接触抱合的包容与被包容螺纹节数，根据应用工况进行设计，通过双向锥形内螺纹锥形孔双向包容双向锥形外螺纹圆锥台体且径向、轴向、角向、周向等多方向定位，优选地，通过双向锥形孔包容双向圆锥台体且以径向、周向的主定位辅之于轴向、角向的辅助定位进而形成内、外圆锥体的多方向定位直至双向锥形孔圆锥面与双向圆锥台体圆锥面抱合实现自定位或直至定径过盈接触产生自锁，构成一种特殊的圆锥副与螺纹副的合成技术，确保锥形螺纹技术尤其是非对称双向锥形螺纹连接副的传动连接的精度、效率和可靠性。
本双向锥形螺纹连接副紧固连接、密封连接时，其连接性能、锁紧性能、防松性能、承载性能和密封性能等技术性能是通过双向锥形孔与双向圆锥台体的旋合连接实现的，即圆锥台体第一螺旋状圆锥面与锥形孔第一螺旋状圆锥面定径直至过盈和/或圆锥台体第二螺旋状圆锥面与锥形孔第二螺旋状圆锥面定径直至过盈和/或圆锥台体第一螺旋状圆锥面与锥形孔第二螺旋状圆锥面定径直至过盈 和/或圆锥台体第二螺旋状圆锥面与锥形孔第一螺旋状圆锥面定径直至过盈实现的，根据应用工况，达到一个方向承载和/或两个方向同时分别承载，即双向圆锥台体与双向锥形孔在螺旋线的引导下内圆锥与外圆锥内外径定心直至锥形孔第一螺旋状圆锥面与圆锥台体第一螺旋状圆锥面抱合达到一个方向承载或两个方向同时承载定径配合或直至定径过盈接触和/或锥形孔第二螺旋状圆锥面与圆锥台体第二螺旋状圆锥面抱合达到一个方向承载或两个方向同时承载定径配合或直至定径过盈接触和/或锥形孔第二螺旋状圆锥面与圆锥台体第一螺旋状圆锥面抱合达到一个方向承载或两个方向同时承载定径配合或直至定径过盈接触和/或锥形孔第一螺旋状圆锥面与圆锥台体第二螺旋状圆锥面抱合达到一个方向承载或两个方向同时承载定径配合或直至定径过盈接触，通过双向内圆锥包容双向外圆锥且径向、轴向、角向、周向等多方向定位，优选地，通过双向锥形孔包容双向圆锥台体且以径向、周向的主定位辅之于轴向、角向的辅助定位进而形成内、外圆锥体的多方向定位直至双向锥形孔圆锥面与双向圆锥台体圆锥面抱合实现自定位或直至定径过盈接触产生自锁，构成一种特殊的圆锥副与螺纹副的合成技术，从而实现机械紧固机构的连接性能、锁紧性能、防松性能、承载性能和密封性能等技术性能。
因此，本非对称双向锥形螺纹连接副机械紧固机构传动精度效率高低、承力能力大小、自锁之锁紧力大小、防松能力大小、密封性能好坏等技术性能与圆锥台体第一螺旋状圆锥面及其形成的左侧锥度即其所对应第一锥角α1和圆锥台体第二螺旋状圆锥面及其形成的右侧锥度即其所对应第二锥角α2和锥形孔第一螺旋状圆锥面及其形成的左侧锥度即其所对应第一锥角α1和锥形孔第二螺旋状圆锥面及其形成的右侧锥度即其所对应第二锥角α2的大小有关。
换言之，要达到圆锥配合的自锁性和自定位能力，并非任意锥角或者说任意锥度均可，即本非对称双向锥形螺纹连接副的锁紧性能、防松性能、承载性能以及密封性能等技术性能，主要取决于非对称双向锥形螺纹的内螺纹外螺纹的第一螺旋状圆锥面及其形成的左侧锥度即其所对应第一锥角和内螺纹外螺纹的第二螺旋状圆锥面及其形成的右侧锥度即其所对应第二锥角，柱状母体和筒状母体的材料材质摩擦系数、加工质量、应用工况也有一定影响。
在上述的非对称双向锥形螺纹连接副中，所述的直角梯形结合体匀速回转一周时所述的直角梯形结合体轴向移动的距离为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直角边之和的长度的至少一倍。该结构保证了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以及锥形孔第一螺旋状圆锥面和锥形孔第二螺旋状圆锥面具有足够长度，从而保证双向圆锥台体圆锥面与双向锥形孔圆锥面配合时具有足够有效接触面积和强度以及螺旋运动所需要的效率。
在上述的非对称双向锥形螺纹连接副中，所述的直角梯形结合体匀速回转一周时所述的直角梯形结合体轴向移动的距离等于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直角边之和的长度。该结构保证了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以及锥形孔第一螺旋状圆锥面和锥形孔第二螺旋状圆锥面具有足够长度，从而保证双向圆锥台体圆锥面与双向锥形孔圆锥面配合时具有足够有效接触面积和强度以及螺旋运动所需要的效率。
在上述的非对称双向锥形螺纹连接副中，所述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均为连续螺旋面或非连续螺旋面；所述的锥形孔第一螺旋状圆锥面和锥形孔第二螺旋状圆锥面均为连续螺旋面或非连续螺旋面。优选地，这里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以及锥形孔第一螺旋状圆锥面和锥形孔第二螺旋状圆锥面均为连续螺旋面。
在上述的非对称双向锥形螺纹连接副中，所述筒状母体连接孔旋入所述的柱状母体的旋入端时，有旋入方向要求，即筒状母体连接孔不能反方向旋入，这里的内螺纹和/或外螺纹的第一螺旋状圆锥面的两条素线间的夹角即第一锥角与内螺纹和/或外螺纹的第二螺旋状圆锥面的两条素线间的夹角即第二锥角的所对应的锥度方向相反和/或相向。
在上述的非对称双向锥形螺纹连接副中，所述的柱状母体的一端设有尺寸大于柱状母体外径的头部和/或所述的柱状母体的一端和/或两端都设有小于柱状母体螺杆体的双向锥形外螺纹小径的头部，所述的连接孔为设于螺母上的螺纹孔。即这里的柱状母体与头部连接为螺栓，没有头部和/或两端头部小于双向锥形外螺纹小径的和/或中间没有螺纹两端各有双向锥形外螺纹的为螺柱，连接孔设置 在螺母内。
与现有的技术相比，本非对称双向锥形螺纹连接副的优点在于：设计合理，结构简单，通过内、外圆锥同轴内外径定心形成的圆锥副双向承载或定径直至过盈配合来实现紧固和连接功能，操作方便，锁紧力大，承力值大，防松性能良好，传动效率和精度高，机械密封效果好，稳定性好，能防止连接时出现松脱现象，具有自锁和自定位功能。
