蜗轮用Worm gear

蜗轮是一种机械传动件，通常由蜗杆和蜗轮组成。蜗轮外圆编程需要考虑其轮廓形状和加工工艺，一般可以采用数控加工技术进行编程。以下是一些可能涉及到的编程步骤：1.确定蜗轮的轮廓形状和尺寸：可以通过图纸或三维模型获取蜗轮的外形和尺寸信息，根据这些信息来确定编程参数。2.选择合适的数控加工机床：蜗轮外圆通常采用数控车床或数控磨床进行加工。选择合适的数控加工机床可以确保加工精度和效率。3.编写数控程序：根据蜗轮的轮廓形状和加工工艺，编写数控程序。数控程序需要包括加工路径、加工速度、切削深度等加工参数。4.进行加工：在数控加工机床上加载数控程序，进行蜗轮外圆的加工。需要注意的是，蜗轮的加工需要较高的精度和技术要求，通常需要经过多道工序进行加工和检验。因此，在进行加工之前，需要充分了解蜗轮的加工要求和相关技术规范。以下是一些可能用到的数控加工程序指令（G代码）：G00：快速移动G01：直线插补G02/G03：圆弧插补（顺时针/逆时针）G40/G41/G42：刀具半径补偿（取消/左偏/右偏）G90/G91：绝对/相对距离指令M03/M04：主轴正/反转M08/M09：冷却液开/关这些指令需要结合具体加工情况进行调整和编写。为了确保程序的正确性和安全性，建议在编写程序前先进行加工路径模拟和机床仿真，并在加工过程中进行实时监控和调整。

齿轮按齿圈上的轮齿分布形式可分为，直齿，斜齿，人字齿，锥齿（常见的）。按轮体的结构可分为盘类齿，套类齿，轴类齿，条类齿等。

Gears are often through-hardened by water or oil quenching in order to increase their resistance to wear. 齿轮通常都要经过在油介质或者水介质中的整体淬火，以达到增加耐磨性的目的。If a low degree of hardness is satisfactory, through-hardening is probably the most desirable heat treatment process to be used because of its inexpensiveness. 如果对强度的要求较低，整体淬火可能是最适当的热处理方法，因为它的花费不高。Case hardening is used for gear that require a hard surface and for which good accuracy is not necessary. 局部淬火使用在那些要求表面硬度较高的齿轮上，而且很难精确的达到。The case hardening process results in gears that have much harder surfaces than cores. 局部淬火处理的齿轮具有比心部组织硬度高的表面硬度。The advantage of case hardening is that, while the surface becomes hard and wear resistant, the toughness associated with the core remains.局部淬火的优点是，表面具有高硬度和高耐磨性的同时，心部组织仍然保留着较高的韧性。Carburizing, cyaniding, and induction hardening are some of the processes commonly used to produce the case hardening effect. 碳化、氰化、感应淬火是局部淬火中经常使用的处理方法。If great accuracy is required, the gear must be ground. 如果对齿轮有精度要求，齿轮就必须经过磨削。For problems in which corrosion resistant surfaces are desirable, nitriding is the process most often used. However, nitriding is a relatively expensive process and is used only if other processes do not produce satisfactory results. 对于表面有抗腐蚀性要求的齿轮，渗氮是最常用的方法。然而，渗氮是一种相对较昂贵的热处理方法，并且通常只在其它热处理方法无法满足要求时才会使用。Flame hardening and induction hardening are the methods usually used to harden larger gears. 火焰淬火和感应淬火是经常在大型齿轮上使用的热处理方法。To sum up this discussion of specially heat treated steels, the designer should make use of carbon or alloy steels without special heat treatment if the relatively low surface hardening of these untreated materials is satisfactory. 作为对特殊热处理钢材讨论的总结，设计师应当在未经热处理的低表面硬度材料能够满足使用要求时，使用不经过特殊热处理的碳钢或合金钢。As the hardness requirement increase, the heat treated steels should be considered, with the least expensive steel that satisfies the strength and wear requirements being chosen. 随着硬度要求的增加，应当考虑选择能够达到强度、耐磨性要求的最便宜的热处理钢材。Nonferrous Metals Gears have been manufactured of nonmetallic materials for many years. 用非金属材料来制造齿轮已经有很长时间。Rawhide, nylon, various type of plastics, and so on, have been used. The advantages obtained by using these materials are quiet operation, internal lubrication, dampening of shock and vibration, and manufacturing economy. 生牛皮、尼龙、各种塑料、以及其它材料都得到应用。这些材料的优点有:静音操作、自润滑、减振性好、以及加工制造经济性好。Their primary disadvantages are lower load carrying capacity and low heat conductivity, which results in heat distortion of the teeth and many result in a serious weakening of the gear teeth. 它们的主要缺点是承载能力低和热传导性差，这些引起了轮齿的热变形和多种轮齿能力的降低。Recently thermoplastic resins, with glass-fiber reinforcement and a lubricant as additives, have been used as gear materials. 最近，一种由玻璃纤维加固、并且带有自润滑剂的热塑性塑料，已经被用来做齿轮材料。The composite material has resulted in greater load carrying capacity, a reduced thermal expansion, greater wear resistance and fatigue endurance.合成材料具有更好的承载能力，更低的热膨胀系数，更好的耐磨性和更好的抗疲劳性能。问题补充：Nonferrous Metals Nonmetallic Materials 麻烦翻译达人了！补充这句是有点问题，Nonferrous Metals是有色金属。Nonmetallic Materials是非金属材料。用有色金属制非金属材料齿轮显然不对，我把那句翻成用非金属材料制非金属齿轮了。你对照下原文再。问题补充：还漏了一段：Copper, zinc, aluminum, and titanium and titanium are materials used to obtain alloys that are useful gear materials. 铜、锌、铝和钛是经常使用在齿轮材料中的合金金属。The copper alloys, known as bronzes, are perhaps the most widely used. 铜合金，比如青铜，可能是应用最广泛的合金。They are useful in problems where corrosion resistance is important and also where large sliding velocities exist. 它们用在要求有较高耐腐蚀性的情况，以及有较大滑动速度存在时。Because of their ability to reduce friction and wear, they are usually used as the material for making the worm wheel in a worm gear set. 因为具有减摩性和耐磨性的性能，它们通常用来制作涡轮减速器中的涡轮。Aluminum and zinc alloys are used to manufacture gears by the diecasting process.铝和锌的合金用来在模铸法中制造齿轮。

齿轮传动的类型很多，按照不同的分类方法可分为不同的类型。1、按传动比根据一对齿轮传动的传动比是否恒定来分，可分为定传动比和变传动比齿轮传动。变传动比齿轮传动机构中齿轮一般是非圆形的，所以又称为非圆齿轮传动，它主要用于一些具有特殊要求的机械中。而定传动比齿轮传动机构中的齿轮都是圆形的，所以又称为圆形齿轮传动。定传动比齿轮传动的类型很多，根据其主、从动轮回转轴线是否平行，又可将它分为两类，即平面齿轮传动和空间齿轮传动。2、按齿廓形状按齿廓曲线的形状不同，可分为渐开线齿轮传动、摆线齿轮传动、圆弧齿轮传动和抛物线齿轮传动等。其中渐开线齿轮传动应用最为广泛。3、按工作条件按齿轮传动的工作条件不同，可分为闭式齿轮传动、开式齿轮传动和半开式齿轮传动。开式齿轮传动中轮齿外露，灰尘易于落在齿面；闭式齿轮传动中轮齿封闭在箱体内，可保证良好的工作条件，应用广泛；半开式齿轮传动比开式齿轮传动工作条件要好，大齿轮部分浸入抽池内并有简单的防护罩，但仍有外物侵入。4、按齿面硬度根据齿面硬度不同分为软齿面齿轮传动和硬齿面齿轮传动。当两轮（或其中有一轮）齿面硬度≤350HBW时，称为软齿面传动；当两轮的齿面硬度均>350HBW时，称为硬齿面传动。软齿面齿轮传动常用于对精度要求不太高的一般中、低速齿轮传动，硬齿面齿轮传动常用于要求承载能力强、结构紧凑的齿轮传动。齿轮传动的类型虽然很多，但渐开线直齿圆柱齿轮传动是其中最简单、最基本的类型。

两轴在空中成直交时常用的齿轮。齿轮速比差可达一比一零零，但效率反而不佳。因具有不倒转的特性，故常用于起重机的升降。

主要是由齿轮类型确定处置之轴;此外,某些类型的变量比其他人更适合大型速度的变化。这意味着如果一个特定的性格在轴上是必须的,该类型的齿轮将或多或少是固定的。另一方面,如果一个所需要的速度转变需要某一类型、轴的位置也会被修正。直齿圆柱齿轮、斜齿轮。一个齿轮有蛀牙的要素,它笔直平行轴是众所周知的齿轮。对一个刺激可以用来连接平行轴而已。 直齿圆柱齿轮、斜齿轮。一个齿轮有蛀牙的要素,它笔直平行轴是众所周知的齿轮。对一个刺激可以用来连接平行轴而已。 如果一个渐开线直齿圆柱齿轮是由橡胶和扭曲的统一,使结束关于轴旋转,相对于彼此的元素,最初的牙齿笔直平行轴,将成为一圈。在齿轮的效果将会变成一个螺旋齿轮。蠕虫和伞齿轮。为了实现线接触,提高承载能力的交叉轴斜齿轮,齿轮的曲线,就可以将部分地绕齿轮,以多多少少相同的方式包围着一个螺丝螺母。其结果将是一个圆柱蜗杆和齿轮。蠕虫是也出现了形体的承载能力,进一步增强了。涡轮齿轮提供最简单的意味着获得大的比例,在一个单一的一对。他们通常是更有效率的比parallel-shaft齿轮,然而,由于额外的一个滑动运动沿牙齿。

In helical gears instead composed of cylindrical worm worm helical gear mechanism to overcome this disadvantage can be a good and retain the advantage. In the automotive field, this transmission mechanism widely used, often with plastic instead of metal materials to produce helical gears. Cylindrical Worm Helical Gear coincidence degree size affects the stability of the entire transmission process and the size of the noise.

求英文高手帮我翻译一个文章（汉译英，机械类） 悬赏分：10 - 离问题结束还有 14 天 23 小时Mechanics Components Charles W. Beardsley Gears Spur and helical gears. A gear having tooth elements that are straight and parallel to its axis is known as a spur gear. A spur pair can be used to connect parallel shafts only. Parallel shafts, however, can also be connected by gears of another type, and a spur gear can be mated with a gear of a different type. To prevent jamming as a result of thermal expansion, to aid lubrication, and to compensate for unavoidable inaccuracies in manufacture, all power-transmitting gears must have backlash. This means that on the pitch circles of a mating pair, the space width on the pinion must be slightly greater than the tooth thickness on the gear, and vice versa. On instrument gears, backlash can be eliminated by using a gear split down its middle, one half being rot table relative to the other A spring forces the split gear teeth to occupy the full width of the pinion space. Helical gears have certain advantages; for example, when connecting parallel shafts they have a higher load carrying capacity than spur gears with the same tooth numbers and cut with the same cutter. Because of the overlapping action of the teeth, they are smoother in action and can operate at higher pitch-line velocities than spur gears. The pitch-line velocity is the velocity of the pitch circle. Since the teeth are inclined to the axis of rotation, helical gears create an axial thrust. If used singly, this thrust must be absorbed in the shaft bearings. The thrust problem can be overcome by cutting two sets of opposed helical teeth on the same blank. Depending on the method of manufacture, the gear may be of the continuous-tooth herringbone variety or a double-helical gear with a space between the two halves to permit the cutting tool to run out. Double-helical gears are well suited for the efficient transmission of power at high speeds. Helical gears can also be used to connect nonparallel, non-intersecting shafts at any angle to one another. Ninety degrees is the commonest angle at which such gears are used. Worm and bevel gears. In order to achieve line contact and improve the load-carrying capacity of the crossed axis helical gears, the gear can be made to curve partially around the pinion, in somewhat the same way that a nut envelops a screw. The result would be a cylindrical worm and gear. Worm gears provide the simplest means of obtaining large ratios in a single pair. They are usually less efficient than parallel-shaft gears, however, because of an additional sliding movement along the teeth. Because of their similarity, the efficiency 55 of a worm and gear depends on the same factors as the efficiency of a screw. Single-thread worms of large diameter have small lead angles and low efficiencies. Multiple-thread

利用递归关键的是找出要删除节点的父节点(假如是C)，找到父节点C之后继续利用递归找出C的父节点B，找到父节点B之后继续找出B的父节点A. . 还需要加一个判断，判断一下 父节点.Parent.Parent 看部分代码：string parentName="";private void 删除选中节点ToolStripMenuItem_Click(object sender, EventArgs e){ try { TreeNode node = treeView1.SelectedNode.Parent; if (ChuLi.deleteNode(NodeId))//这个是我自己定义的方法，大家可以忽略 { if (node != null)//如果是子节点不是根节点，那么就展开 { parentName = node.Text; //展开的应该是父节点 ExpandNodes(treeView1.Nodes);//调用----------------------------------------- } } else { MessageBox.Show("删除失败！"); } } catch (Exception ex) { MessageBox.Show(ex.Message); }}//遍历所有节点，找出指定节点private void ExpandNodes(TreeNodeCollection tnodes){ foreach (TreeNode node in tnodes) { if (node.Text == parentname)//比较判断，所以需要知道所选节点的父节点名字：node.Parent.Text { ExpandParentNodes(node.Parent.Nodes);//调用下一个递归方法 } ExpandNodes(node.Nodes); }}//关键点所在private void ExpandParentNodes(TreeNodeCollection tnodes){ TreeNode parentNode; foreach (TreeNode node in tnodes) { parentNode = node; if (parentNode.Parent != null) { parentNode.Parent.Expand(); if (parentNode.Parent.Parent != null)//判断父节点的父节点是否为空，如果已经达到根节点就是null { ExpandParentNodes(parentNode.Parent.Parent.Nodes); } else break;//已经达到根节点，退出 } }}

Apache是开放源代码的Web服务器软件，是最常用的Web服务器。Apache常用在unix系统，也有windows平台的版本。本文以windows平台为例，介绍使用动态域名安装配置Apache建设网站的方法。（一）申请安装动态域名解析——每步一、申请帐号1、打开http://www.meibu.com2、点击上面的用户注册3、按照提示输入注册信息如图：前面带*号的是必须要填的，提示注册成功即可。二、下载客户端软件可到http://www.meibu.com/khd.asp下载相应版本。外网IP地址就在服务器上的用户选择2008版本。三、安装下载完后，运行安装文件，按照提示安装完成即可。四、使用（这里以2008版本为例，其它版本也一样设置）1、运行桌面上的“ddns2008”图标2、运行后将在系统托盘上看到动态域名解析2008版的图标。3、双击图标，弹出设置对话框，输入你刚才申请的域名abc.meibu.com和密码。客户端提示“登陆成功”后，则可在开始运行里输入“ping abc.meibu.com”，Ping命令反馈的IP地址应该与使用Winipcfg所查看到的系统主机当前IP地址一致。如果确认两者相同，则表明每步的动态域名解析已经处在正常运行状态下。（二） 安装 Apache一. 下载windows平台的Apache可以在这个网址下载：http://hzcnc1.skycn.com/down/apache_2.2.4-win32-x86-no_ssl.zip二. 安装运行下载的Apache文件，即可开始安装。Apache的安装过程很简单。只需要设置下面这个窗口：在“Network Domain”里输入域。如果用本站的二级域名，例如“abc.meibu.com”，请输入“meibu.com”。如果用顶级域名，请输入“xxx.com”。在“Server Name”里输入服务器名。如果用本站的二级域名，请输入您的域名“abc.meibu.com”。如果用顶级域名，请输入“www.xxx.com”。在“Administrator"s Email Address”里输入网站管理员的Email地址。除此之外，安装过程里所有的选项，全部用默认选项就可以了。三、运行Win 9xApache安装后，会在“开始”->“程序”里增加一个“Apache HTTP Server”的组。进入该组，选择“Control Apache Server”->“Start”即可启动Apache。Win NT/2000/XP/2003在这些系统里，用默认选项安装的Apache，除了在“开始”->“程序”里增加一个“Apache HTTP Server”的组之外,还会在系统的服务里增加一个Apache服务.该服务被设置为系统启动时自动运行。四、配置 Apache1、配置文件Apache是一个后台运行的程序，没有界面。所有的配置，都包含在配置文件里。主配置文件是：C:Program FilesApache GroupApacheconfhttpd.conf如果要修改Apache的配置，可以用任何一个文本编辑工具（例如记事本）编辑这个配置文件。在配置文件里，以“#”开头的行是注释行。2、配置选项在配置文件里的主要选项如下：#Listen 3000#Listen 12.34.56.78:80Apache的IP地址和端口。一般来说不需要设置，Apache会绑定在本机所有IP地址的80端口上。Port 80Apache的端口。默认值是80。ServerName abc.meibu.comWeb服务器的名字。安装时输入的“Server Name”就是保存在这里。DocumentRoot "C:/Program Files/Apache Group/Apache/htdocs"这是网站的根目录。如果您想把网站文件存放在“D:myweb”目录下，可以把DocumentRoot后面的目录修改为“D:/myweb”。Options Indexes FollowSymLinks MultiViews为了安全起见，请把上面的“Indexes”删掉。否则别人可以浏览到您网站里的所有文件。DirectoryIndex index.html默认首页文件名。在浏览器里输入一个地址（例如http:// abc.meibu.com/）的时候，Apache会查找这个默认的首页文件打开。如果要配置多个默认首页文件名，请用空格分开。ScriptAlias /cgi-bin/ "C:/Program Files/Apache Group/Apache/cgi-bin/"CGI文件存放路径。五、高级配置1、设置虚拟目录在配置文件中找下面这行：<IfModule mod_alias.c>在这行下面添加如下内容：Alias /vdir/ "c:/comexe/"<Directory "c:/comexe/">Options MultiViewsAllowOverride NoneOrder allow,denyAllow from all</Directory>这样，通过访问 http:// abc.meibu.com/vdir/，就可以访问到c:comexe目录下的内容。Apache默认开设了两个虚拟目录：“/icons/”和“/manual/”。这两个虚拟目录没有用，可以在配置文件中删除。六、常见问题1、如何解决中文网页显示乱码在配置文件中找包含“Addlanguage”或“AddCharset”的行，在这些行最前面增加一行：AddDefaultCharset GB2312养成良好的习惯，在每个网页的<head></head>里加入这行：<meta http-equiv="Content-Type" content="text/html; charset=gb2312">一般的中文版网页编辑工具（例如FrontPage、Dreamweaver等）都会自动加上这行。2、如何解决中文文件名无法访问在ie中选择 工具 -> internet选项 -> 高级 -> 取消“总是以UTF-8发送URL”。这个方法很麻烦，请尽量不要使用中文的网站文件名。3. 在winxp sp2下安装的apache+php5+mysql5,其他电脑无法正常访问我们的网站！出现如下错误：ForbiddenYou don"t have permission to access / on this server.这个错误的原因是，用户没有权限访问你的网站目录。解决办法：打开的apache的配置文件：httpd.conf在末尾添加如下代码：yourpath你的网站目录<Directory "d:/yourpath/"> Allow from all </Directory>保存之后，记得重启apache服务，问题就解决了。请注意：1.Apache配置过程中最关键的两点是：网站根目录和默认首页文件名。必须要把网站文件放在所指定的网站根目录下，而且默认首页文件名必须要设置正确，否则将看不到您的网页。2.每次配置文件更改后，要重新启动Apache才会生效。
