毕业设计（论文）-履带式行走装置的总体方案设计精选.doc

摘 要 本文在详述的基础上，对结构进行了设计，对一些关键部分进行了设计计算。 关键词： 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. Chinas 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 a complete 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 and components. 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 rough description. This article also details the system design, including speed shaft, gear selection and verification. Keywords: the overall design, wheel, supporting wheels, slowing the Department 目 录 I Abstract II 1 绪 论 I 2. 履带式行走装置的总体方案设计 1 2.1 履带式行走装置的功用与组成 1 2.2 履带式行走装置的特点 2 2.3 履带式行走装置的各部分的功用及结构布置 2 2.4 履带式行走装置的尺寸参数 4 2.5 履带式行走装置的接地比压 5 2.6 运行阻力计算 9 3 拟定和分析传动方案 14 4 传动方案的总体设计及各零部件的设计 15 4.1选择液压马达 15
