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.

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

特别简单，我刚检测完事。在七牛云开发者平台页面选择 CDN ，选择域名管理，可以查看具体域名的状态。如果显示创建域名处理中，通常情况下 10-30 分钟完成了。如果当域名状态显示成功，表示域名已经创建成功，下一步排查就是选择对象存储，点击具体的对象存储空间后，在空间概览中查看 CDN 加速域名的状态，看看是成功还是等待就行了。

中括号是构造矩阵用的。[-2,-1.1]就是一个1行2列的矩阵（也就是行向量），依次类推。plot只有一个参数时，会将参数作为纵坐标，以正整数序列（1,2,3,...）做为横坐标绘制曲线；有两个参数时，以第一个参数做横坐标，第二个参数做纵坐标。我想不用具体解释四个命令了，原则说明白您就应该明白了。

如果Apache有漏洞，服务器就被黑了。我在一台RHEL4上编译安装了Apache，用了全默认参数，使用下面命令启动/usr/local/apache/bin/apachectl start看系统里的情况[root@localhost conf]# ps -ef | grep httpd | grep -v grep[root@localhost conf]# cat httpd.conf | grep daemon# httpd daemons, you will need to change at least LockFile and PidFile.User daemonGroup daemon # socket used to communicate with the CGI daemon of mod_cgid.试下把daemon改成root看看[root@localhost conf]# /usr/local/apache/bin/apachectl startSyntax error on line 65 of /usr/local/apache/conf/httpd.conf:Error:tApache has not been designed to serve pages whilentrunning as root. There are known race conditions thatntwill allow any local user to read any file on the system.ntIf you still desire to serve pages as root thenntadd -DBIG_SECURITY_HOLE to the CFLAGS env variablentand then rebuild the server.ntIt is strongly suggested that you instead modify the Userntdirective in your httpd.conf file to list a non-rootntuser.n[root@localhost conf]# cat httpd.conf | grep root# httpd as root initially and it will switch.User rootGroup root可以看到，Apache根本不给你启动！根据Apache的文档里这么描述如果配置文件中Listen定义的是默认的80端口(或1024以下)，那么启动Apache将需要root权限以将它绑定在特权端口上。一旦服务器开始启动并完成了一些诸如打开日志文件之类的准备操作，它将创建很多子进程来完成一些诸如侦听和回应客户端请求的工作。httpd主进程仍然以root用户的权限运行，而它的子进程将以一个较低权限的用户运行。这将由你选择的多路处理模块进行控制。所以，用root启动Apache并不存在安全问题。非root用户不能启动1024以下的端口，所以非root启动Apache不能启动80，443端口，到时候再用iptable做跳转就是很麻烦的事情，而且iptables性能也是问题。像bind这样的程序使用的是chroot的方式来解决权限控制问题，用root启动一样没有安全问题。有些时候源码天空，这些想法都是人传人，大多数人不仔细想想，找找内因。
