带式输送机自动张紧装置设计【4张图纸】【优秀】

摘  要

设计一种液压自动张紧装置对带式输送机的张紧过程很有必要，在分析其他几种张紧装置的优缺点的同时，这种张紧装置具有工作较平稳、响应快、具有断带保护和打滑保护、对空间要求低、性能可靠等优点。是一种较先进、较完善、适合于大型带式输送机的张紧装置。本文从三部分（液压回路设计、元件的确定、主要部件的设计和计算）对此种液压自动张紧装置进行了分析，同时利用AutoCAD绘图软件绘制了结构布置图、零件图及装配图等。

ABSTRACT

Design a hydraulic automatic tensioner devices on belt conveyors tensioner process is necessary,on the analysis of other advantages and disadvantages of several tensioner device at the same time,the tensioner device has the work is smooth, fast response, has broken with protection and sliding protection, to space low demand, reliable performance, etc. Is a kind of more advanced, more perfect, suitable for large belt conveyor tensioning devise. This article from the third part (hydraulic circuit design, components of the main parts of the determination, the design and calculating) this type of hydraulic automatic tensioner device are analyzed, At the same time use AutoCAD mapped the structure arrangement, parts graph and assembly, etc.

Keywords: Belt conveyor; Automatic tensioning devise; Hydraulic system; Tensioner hydraulic cylinder; Hydraulic pump;  motor
