中国地质大学长城学院本科毕业论文外文资料翻译系 别： 工程技术系 专 业：机械设计制造及其自动化姓 名： 阮仁贵 学 号： 05208312 2012 年 3 月 1 日外文资料翻译译文磨损测试机 来源：美国专利局应用 7 月 22,1949 1883，作为修订 1928 年 4 月 30 日 ； 3，3 月的行为根据批 370 第 G.757 作者：乔治布莱克，蒙哥马利县，马里兰州，和埃德温r.paul，华盛顿，华盛顿 本文所发明涉及的是一种耐磨的试验机，这种试验机是一种特别耐磨并且绝缘，使覆盖上面的电线电缆不能通过机器来对人造成安全的威胁。这种磨损试验机采用的是砂轮或锋利的边缘来达到一种磨损或穿透所要磨损的东西。但是，随着试验的结果发现，试验机在工作的时候刀刃由于高速则成为砂轮运转堵塞。在刀刃磨损以外。在其它机器，适用于负载的物体是可变的，在紧张的情况下应用于电线并持续它的表面研磨。本次设计的目的是提供一个机械中负载应用到研磨表面，在正常的情况下不断的在表面进行研磨。另一项发明的目的是提供一个试验机机在一个新的和未使用的部分的研磨表面用于每次的测试。另一目的是研磨圆形，矩形，或其他形状的电缆。其他对象的优势将变得磨损的更加充分以下是具体的说明。在这说明当中体现出原理大大的加速度产生的动力会给传送带的纹理、传送带结合处、驱动滑轮、轴承、减速器以及耦合器带来负面影响。毫无控制的加速度产生的动力能够引起带式传送机系统产生诸多不良问题，比如上下曲线运动、过度传送带提升运动、滑轮和传送带打滑、运输原料的溢出和传送带结构。传送带的设计需要面对两个问题：第一，传送带驱动系统必须能够产生启动带式传送机的最小转动力矩；第二，控制加速度产生动力在安全界限内。可以通过驱动力矩控制设备来完成，控制设备可以是电子手段也可以是机械手段。工作时刀刃是一个垂直移动，它可以枢转地连接到支架臂和中枢轴销。体重连接臂提供了向下的压力，在其下部与压板固定在它的焊接或其他常规手段，和一个通道压板中心圆形电力电缆连接。在实施过程中按物体是松散的加入后由一个球窝关节，其他形状的电缆可以被磨损。工作板还可调，通过固定螺钉并具有指导研磨带。这是拉辊和在其上端，如图所示详细图。轴和滑轮连接到其两侧连接带。可以看出，由于大轮驱动较小数，滑脱是为了将不超过适当的紧张的研磨带。因为它是上转和引脚的取决于驱动装置，它表明大量的绝缘题。一对夹具和固定柱和支架分别接触，完成一个电路时所需金额绝缘已经磨损完成。螺丝可以调整，以便在工作板定位。这样一个新的部分的研磨带可用于每个运行的地带。在操作中，该夹具牵引辊磨料，原来的一些行动的轴可以计算或记录在一个计数器，和接触可能是在一个电路包括继电器开关的电机电路，一个开放的位置。控制开关是在电机电路的操作手册。它应被理解，当然，上述涉及的只有一个首选，许多修改或改变可能是其中没有离开发明的范围中所规定的附加要求。磨损试验机所组成的一个系统，一个支持对卷筒经行运转，夹紧方式对每一个表示支持适应的安全线之间有一间隙，相互支持，一个可移动的横向固定的底座，磨料传带和轴之间，电机和减速器的基础上连接到一对摩擦辊，传动装置和定位之间有连接，驱动方式的轴驱动方式连接一个说卷筒驱动的运动，传送带由此给其他，可移动的驱动系统控制或必须调整相当数量减速的强制在翻修期间吗，翻修发生当运行和开始? 维护和支持系统。各个驱动系统将要求定期预防维护。可替换的项目会包括马达、轴承、闸填充、散逸电阻器、油, 和凉水。如果驱动系统被设计和保守地被管理, 更低的重音在可消耗导致更低的维修费用。一些驱动器要求支持系统譬如流通的油为润滑油、冷却空气或水, 环境尘土过滤, 或计算机仪器工作。支持系统的维护可能影响驱动系统的可靠性。外文原文 Abrasion testing machine United states patent officeApplication July 22,1949,Serial no.106,2663 claims.(cl.73-7) (Granted under the act of march 3, 1883,asamended April 30, 1928; 370 O. G.757)George F.Blackburn,Montgomery county,Md.,and Edwin R.paul,Washington,d.cThis invention relates to abrasion testing machines and in particular to a machine for testing the resistance to abrasion of the insulation or covering on electric wires and cables.At present, abrasion testing machines employ abrasive wheels or sharp edges to wear away or penetrate the insulation or covering on cables. It has been found that knife edges rapidly become dull and abrasive wheels become clogged with the material as it is abraded away. In other machines, the load applied to the specimen wire is variable with the tension applied to the wire to hold it over the abrading surface. The present invention has for its object to provide a machine in which the load applied to the abrading surface may be held normal and constant at any desired value.Another object of the invention is to provide a machine in which a new and unused section of an abrading surface may be used for each test.Another object of the invention is to abrade either round, rectangular, or other shaped electric cables.Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the annexed drawings, which illustrate preferred embodiments, and wherein.:Fig.1 shows an elevational view of the invention.Fig.2 shows a view in elevation of a portion of the invention.Fig.3 shows a partial view partly in section of another embodiment of the invention,andFig.4 shows a view insection of a portion of the invention taken on line44 of Fig.1.Referring in more particular to the drawing, in Fig. 1,a base 10 has secured to it a support 11 for holding electric motor12 and reduction gear unit 12. Also secured to base 10 is post 14 having at its upper end a work plate 15 secured by set screws 15 and supporting a dial indicator gauge 16 by means of off-set bracket 17 and adjustable clamp 18 , as seen in Fig.2.Positioned between the work plate 15 and the gauge 16 is a vertically movable post 19 pivotally connected to off-set bracket 17 by arms 20, 21 and pivot pins 22. Weight 23 is attached to arm 21 and provides downward pressure to post 19.Post 19 has at its lower and press plate 24 secured to it by welding or other conventional means, and a channel 25 in the press plate 24 serves to center a round electric cable 26.In the embodiment shown it Fig.3, press plate24 is loosely joined to post 19 by a ball and socket joint 25 in order that other shaped cables 26 may be abraded.Work plate 15 is adjustable on post 14 by means of set screws 15 and has guides 27 to guide the abrasive strip 28 as it is pulled by rollers 29 and 30 from reel 31 to take up reel 32, which are supported by posts 33 and 34 having clamps 35 and 36 at their upper ends respectively, as shown in detail in Fig.4.Reels 31 and 32 have pulleys 37 and 38 attached to their sides and are connected by belt 39.It will be seen that owing to the larger pulley 37 driving the smaller one 38,an amount of slippage is needed in order to apply no more than the proper tension to the abrasive strip 28 as it is wound on the take-up reel 32.Pin 40 of the guage 16 rests on the post19 and actuates the guage16 to indicate the amount of insulation abraded from the wire 26 or 26. A pair of clamps 41 and 42 are fixed to post 19 and bracket 17 respectively and have contacts 43 to complete an electrical circuit when a desired amount of insulation has been worn away.Set screws 15 may be adjusted in order that the work plate 15 can be positioned on post 14 so that a fresh part of the abrasive strip 28 may be used for each rerun of the strip.In operation,the wire 26 is held by clamps 35 and 36 and with the rollers 29 and 30 pulling the abrasive strip 28 ,the number of turns of the take-up reel 32 may be counted or recorded on a counter 44, and the contacts 43 may be in a circuit including a relay 45 to actuating switch 46 in the motor circuit to an open position, as shown in Fig. 1.A control switch 47 is shown in the motor circuit for manual operation.It should be understood, of course, that the foregoing disclosure relates to only a preferred embodiment (or embodiments) of the invention and that numerous modifications or alterations may be made therein without departing from the spirit and the scope of the invention as set forth in the appended claims.The invention described herein may be manufactured and used by or for the Government of 50 the United States of America for governmental purposes without the payment of any royalties thereon or therefore.1.An abrasion testing machine for insulated55 wires comprising a base,a pair of supports for Reels secured thereon, clamping means one on each of said supports adapted to secure a wire there between, a reel on each support, a laterally movable anvil secured to said base over which said wire is held, an abrasive tape wound on and between said reels and passing over said anvil under said wire, a motor and reduction gear on said base drivably connected to a pair of friction rollers having said tape drivably positioned there between, driving means connecting the one of said reels driven means connecting the one of said reels driven by the movement of said tape therefrom to the other or take-up reel, movable holding means on said base positioned over said anvil adapted to press said wire against said tape on said anvil, tape guiding means on said anvil, means for moving said anvil and said tape-guiding means
