专业英语~麻烦各位翻译一下

关于电动葫芦名称的由来，社会上有三种说法：

外形像植物葫芦，下图自己看：

2.电动葫芦起源于西方，原名Electric Hoist（电动提升机），而Hoist读音近似于“葫芦”。

3.葫芦在中国传统文化中的特定涵义，像童话故事中的葫芦娃、西游记等神话故事中的宝葫芦，都是以小博大、四两拨千斤的神奇物件；再者葫芦发音近似“福禄”，正好讨个好彩头。

〖科普〗

电动葫芦：是一种特种起重设备，安装于天车（电动单梁桥式起重机）、龙门吊（电动葫芦门式起重机）之上，电动葫芦具有体积小、自重轻、操作简单、使用方便等特点，用于工矿企业、仓储码头等场所。电动葫芦用于起重量较小的场合，通常大于25t的起重工况都采用卷扬小车模式。

电动葫芦起重量一般为 0.1～80吨（最常用的是2t、5t、10t、20t、25t等几种规格），起升高度为3～30米。分为钢丝绳电动葫芦和环链电动葫芦两种。钢丝绳电动葫芦由电动机、传动机构和起升装置（卷筒/钢丝绳/吊钩）、走行机构（墙板车轮）组成。

电动葫芦按起升速度模式可分为单速提升CD型、双速提升MD型、变频调速NZ型。

用于双梁桥式起重机上的电动葫芦则采用欧式葫芦小车样式（NZS型）。

Electric hoist bridge crane is a small light lifting equipment. Gourd with small size, light weight, simple operation, easy-to-use features such as for industrial and mining enterprises, storage terminals and other places.By electric hoist motor, drive mechanism and the composition of drum or sprocket can be used alone can also be assembled together with the car flying in the use of a crane beam, LH electric double-beam bridge crane hoist with the traditional double-beam bridge crane is the difference between electric hoist drum to replace the small car, motor. Reducers, brakes and other lifting devices. This article mainly deals with electric hoist bridge crane to do the main body of analysis and calculation, including the electric hoist lifting body, and the operation of car bodies.

本人也是做机械的，希望多多交流，如下的翻译希望能让你满意，如有不足之处，还望多多指教！

Electrical Hoist is a crane combined by electromotor, speed reducer, roller,brake and crown block. It can be fixed, and also can be assembled with trolly and beam to become single-beam brige crane, twins beam brige crane and electric gantry crane, who can be used for winding with a little modification.

When designing the shaft parts, we need fully consider every neccessary specifications such as the material, heat treatment and precision etc.Besides, we need consider the problems which may occur in or after design, and solve them in time. We should design in accordance with the requirements such as:

* meeting the requirements of strength and stiffness,

* improving the radiating performance and preventing thermal deformation,

* rational structure, and

* good mould and manufacturability.

This article synthetically explains how to confirm the related equipments, cutting parameters, process designing and machining quality analysis with consideration on selcting shaft blank, manufacturing process and final inspection.

This article consists of five parts, Part 1 to introduce why to study this project, Part 2 to explain the electrical hoist's application and function, Part 3 to specify the process for shaft parts of hoist, Part 4 to analyse the problems which may happen in the manufacturing process and the reason and the way to solve the problems, and Part 5 to check if the finished shaft meets the requirements based on the drawings.
