文档介绍：工程钻机—履带行走部分设计
摘要
工程机械是国民经济建设及国防工程施工中使用的重要技术装备,在国民经济建设中,尤其是城市建设、民用建筑、水利建设、道路构筑、机场修建、矿山开采、码头建造、农田改良中,工程机械起着越来越重要的作用。我国的工程机械行业目前进入了一个高速发展阶段,推、挖、装、起重、铲土运输、筑路、农用机械等各种品种齐全并形成了系列化,各种工程机械虽然品种很多但基本上可划分为动力装置、行走装置和工作装置。
履带行走装置的挖掘机履带行驶系统包括车架。行走装置和悬架三部分。车架是整体骨架,用来安装所有的总成和部件。行走装置用来支持机体,把动力装置传到驱动轮上的驱动转矩和旋转运动变为车辆工作与行驶所需的驱动力和速度。悬架是车架和行走装置之间互相传力的连接装置。
本文在详述履带行走装置整体设计的基础上,又对驱动轮、拖链轮、导向轮、支重轮结构进行了设计,对一些关键部分进行了设计校核计算。对各个轮的加工工艺有粗略的描述。本文还详述了减速系统的设计包括轴、齿轮的选择及校核。

Abstract
Construction Machinery is a national economic construction and national defense construction in the importance of the use of technical equipment, construction in the national economy, especially in urban construction, civil construction, water conservancy, road building, airport construction, mining, pier construction, agricultural improvement, mechanical engineering is playing an increasingly important role. China's construction machinery industry has now entered a phase of rapid development, pushing, digging, loading, lifting, shoveling transport, roads, agricultural machinery and other species and formed plete series, all kinds of construction machinery but although many species can basically be classified into power plant, operating equipment and working equipment.
Crawler excavator crawler traveling device system includes the frame. Walking devices and suspension of three parts. Overall skeleton frame is used to install all the assemblies ponents. Walking device used to support the body, the power plant came on the drive wheel torque and rotary movement into a vehicle required for work and driving the driving force and speed. Suspension is a walking frame and transmission device between the connected devices.
In this paper, detailed walking track devices based on the overall design, but also on the driving wheel, drag chain, guide wheel, supporting wheels structure design, for some of the key parts of the design verification calculation. For each round of processing technology has a rou
