6.螺纹问题

求助 BSPT、BSP、BSPP螺纹标准

1、BSP是英制管螺纹。不过,有BSP.Tr., BSP.PI., BSP.F.之分。

BSP.Tr.是锥管螺纹,用于密封接合。

BSP.PI.是平行管螺纹,用于密封接合,只有内螺纹,与BSP.Tr.的外螺纹嵌合。

BSP.F.为平行管螺纹,用于一般的接合。

2、螺紋G與螺紋BSPP一样,均为英制圆柱管螺纹代号牙型角55度

3、英制螺纹有几种?BSP螺纹的特点及表示法?

两种,BSPP(管螺纹)和BSPT(55度角锥管螺纹,与美制60度角锥管螺纹NPT相对,互不兼容)

4、 G螺纹与Rp螺纹对比,哪些地方相同,哪些地方不同,两者在用途上有区别吗,能否通用。

G螺纹与Rp螺纹都是55°圆柱管螺纹。只是国别(组织)不同而产生了不同的代号而已。

G是中国、法国、前苏联、日本的代号;

PF是日本的代号;

BSP、BSPP是英国的代号;

R、K是德国的代号(R是内螺纹、K是外螺纹);

Rp是ISO的代号。

BSPT和NPTF的区别是什么?

BSPT是英制圆锥管螺纹标准指螺纹的牙型角为55° 螺纹具有1:16的锥度

NPTF是干密封标准型锥管螺纹美标螺纹牙形角大多数都是60度

它们的检验方法都可用螺纹通、止规来检验,但所用的螺纹通、止规各不相同。

谢谢给我的解释,我想请教一下BSPT的螺纹规一副是几个,我收到的规是一个规上面有一个台阶的,我想是不是客户少发了,因为干密封锥管螺纹的规一般是三个,L1、L3和六基面规组成的。

一个就可以了,主要看你使用的配合螺纹长度

BSPT应是英制管螺纹统称,分为一般密封管螺纹(R)和非密封管螺纹(G)。

谢谢给我的解释,我想请教一下BSPT的螺纹规一副是几个,我收到的规是一个规上面有一个台阶的,我想是不是客户少发了,因为干密封锥管螺纹的规一般是三个,L1、L3和六基面规组成的。

直管螺纹规有两个:通规和止规。锥管螺纹规只有一个,上面带有标记。一般要测量螺纹规进入深度,超过该标记说明偏大,反之偏小。

7.P.C.D在机械制图的标注上是什么意思啊?

老板给了一张CAD图纸,上面的标注有一个是 P.C.Dφ58 其中P.C.D不知道是什么意思,哪位知道一下

是分度圆直径。

itch circle; standard pitch circle

与分度圆相关的例句

Circular Coin with a Circular Hole 圆孔圆钱

A mark indicating the boundary of such an interval. 刻度线,分度线指示这种间隔的界限的标记

A division or an interval on a graduated scale. 分度,刻度刻度标尺上的一个间隔

The edge of a graduated arc or circle used in an instrument to measure angles. (四分仪等的)分度弧或圆圈,用于量角度。

7.常用单词

绝对尺寸 absolute size 附件 accessory 累积公差 accumulated tolerance 精度,准确度 accuracy

梯形(爱克姆) Acme[screw] 实际内径 actual inside diameter 实际配合 actual fit

图面尺寸 actual measurement on the drawing 实际零件 actual part 实际尺寸 actual size

Unit5 INDUSTRIAL ROBOT工业机器人 INTRODUCTION介绍 Industrial robots are relatively new electromechanical devices that are beginning to change the appearance of modern industry. Industrial robots are not like the science fiction devices that possess human-like abilities and provide companionship with space traveler、Research to enable robots to “see,"hear",“touch",and "listen" has been underway for two decades and is beginning to bear fruit. However,the current technology of industrial robots is such that most robots contain Only an arm rather than all the anatomy a human possesses. Current control only allows these devices to move from point to point in space,performing relatively simple taskes. The Robotics Institute of America defines a robot as“a reprogramrnable multifunction manipulator designed to move material,parts, tools,or other specialized devices through variable programmed motions for the performance of a variety of tasks. "' A NC machining center would qualify as a robot if one were to interpret different types of machining as different functions- Most manufacturing engineers do not consider a NC machining center a robot,even though these machines hive a number of situ- ilarities. The power drive and controllers of both NC machines and robots can be quite similar. Robots, like NC machines can he powered by electrical motors,hydraulic systems,or pnetinlat tc svsterns. Control for either device can lye either open-loop or closed-loop. In fact,many of the developments used in robotics have evolved from the NC industry,and many of the manufactur- ers of robots also manufacture NC machines or NC controllers.工业机器人是相对来说较新的机电设备, 它已经开始改变现代工业的面貌。工业机器人不像科幻小说中的那个模样具有人一样的能力并且能与

英文翻译 机械设计 一台完整机器的设计是一个复杂的过程。机械设计是一项创造性的工作。设计工程师不仅在工作上要有创造性,还必须在机械制图、运动学、工程材料、材料力学和机械制造工艺学等方面具有深厚的基础知识。 Machine Design The complete design of a machine is a complex process. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge. 任何产品在设计时第一步就是选择产品每个部分的构成材料。许多的材料被今天的设计师所使用。对产品的功能,它的外观、材料的成本、制造的成本作出必要的选择是十分重要的。对材料的特性必须事先作出仔细的评估。 One of the first steps in the design of any product is to select the material from which each part is to be made. Numerous materials are available to today's designers. The function of the product, its appearance, the cost of the material, and the cost of fabrication are important in making a selection. A careful evaluation of the properties of a. material must be made prior to any calculations. 仔细精确的计算是必要的,以确保设计的有效性。在任何失败的情况下,最好知道在最初设计中有有缺陷的部件。计算(图纸尺寸)检查是非常重要的。一个小数点的位置放错,就可以导致一个本可以完成的项目失败。设计工作的各个方面都应该检查和复查。 Careful calculations are necessary to ensure the validity of a design. In case of any part failures, it is desirable to know what was done in originally designing the defective components. The checking of calculations (and drawing dimensions) is of utmost importance. The misplacement of one decimal point can ruin an otherwise acceptable project. All aspects of design work should be checked and rechecked. 计算机是一种工具,它能够帮助机械设计师减轻繁琐的计算,并对现有数据提供进一步的分析。互动系统基于计算机的能力,已经使计算机辅助设计(CAD)和计算机辅助制造(CAM)成为了可能。心理学家经常谈论如何使人们适应他们所操作的机器。设计人员的基本职责是努力使机器来适应人们。这并不是一项容易的工作,因为实际上并不存在着一个对所有人来说都是最优的操作范围和操作

In recent years, through several backbone enterprise industry technical transformation, the production scale expands unceasingly, formed the respective characteristics of the products can meet the domestic market # aerial work machinery need, its main economic index of enterprise economic benefits are rising gradually, increasing. 1 Aloft working machinery industry development present situation 1.1 To improve product performance Our aloft working machinery industry backbone enterprises of some use their equipment and technology advantages, through the study, the introduction and digest its own technology and equipment, through the study, introduce advanced foreign technology and developed many new products, the products of the technical level and product quality is improving, and close to the international similar product level # promoted aloft working machinery industry in the domestic market and technological progress in competitive and market demand, the yield increased rapidly. If Beijing hoisting machine factory developed self-traveling shear fork platform, the spider type folding boom platform, aluminum mast section of the box. One box type aluminum mast section of the largest single mast operation platform will reach the height of 16.5 m, Hangzhou and engineering machine's more mast 22m reached alloy platform, hangzhou aichi engineering vehicles Co., LTD develop full hydraulic driving type self-traveling aerial work platform, the maximum height of 26.7 m homework. The above products fill the blank, domestic products have reached the international advanced level. In addition, in the car factory products, fushun crane, jinzhou heavy machinery Co., LTD, xuzhou construction machinery group and chongqing dajiang industrial (group) Co., LTD has developed over 30 aloft work, broken fire only depending on the imported products of domestic situation of the weak. 1.2 Product category and quantity increasing Our work with the mechanical product demand of national economy and the development of urban construction increased year by year, all kinds of new products increased rapidly in recent years. If Beijing hoisting machine factory in just a few short

外文翻译 英文原文 Belt Conveying Systems Development of driving system Among the methods of material conveying employed,belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost.Conveyor systems have become larger and more complex and drive systems have also been going through a process of evolution and will continue to do so.Nowadays,bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine).The ability to control drive acceleration torque is critical to belt conveyors’ performance.An efficient drive system should be able to provide smooth,soft starts while maintaining belt tensions within the specified safe limits.For load sharing on multiple drives.torque and speed control are also important consideratio ns in the drive system’s design. Due to the advances in conveyor drive control technology,at present many more reliable.Cost-effective and performance-driven conveyor drive systems cov ering a wide range of power are available for customers’ choices[1]. 1 Analysis on conveyor drive technologies 1.1 Direct drives Full-voltage starters.With a full-voltage starter design,the conveyor head shaft is direct-coupled to the motor through the gear drive.Direct full-voltage starters are adequate for relatively low-power, simple-profile conveyors.With direct fu11-voltage starters.no control is provided for various conveyor loads and.depending on the ratio between fu11- and no-1oad power requirements,empty starting times can be three or four times faster than full load.The maintenance-free starting system is simple,low-cost and very reliable.However, they cannot control starting torque and maximum stall torque;therefore.they are
