履带是履带式工程机械的主要易损件,质量好坏影响到主机的使用性能和使用寿命。本文根据目前我国履带存在的几个问题,我们将着重介绍组合式履带结构、加工、系列以及在工程机械上如何合理选用等问题。一、组合式履带结构型式及分析1.组合式履带与整体履带的比较目前,国内外履带式工程机械使用的履带总成,大致有整体式(见图1)和组合式(见 Tracks are the main wearing parts of tracked construction machinery, and the quality of the crawler affects the performance and service life of the mainframe. In this paper, according to several problems existing in China’s crawler, we will focus on the issues such as the combined crawler structure, processing, series, and how to reasonably select the construction machinery. First, the combined crawler structure type and analysis 1.Comparison of the combined crawler and the overall crawler At present, tracked assembly used at home and abroad tracked construction machinery, roughly integrated (see Figure 1) and modular (see
