简要介绍了目前国内常用的2种节距刮板输送机无链牵引系统,分析了影响并决定2节销排连接处节距变化的主要因素,分析了2种节距系统的基本状态和失效模式等。在分析目前2种节距刮板输送机无链牵引系统的基础上,从弯曲角度控制、节距控制、销齿修形、配套间隙优化等几个方面对设计更大节距无链牵引系统提供了非常实用的一些建议。
This paper briefly introduces the commonly used chain-type towing system of two kinds of pitch scraper conveyors in our country, analyzes the main factors that influence and determines the change of pitch of two rows of rows and columns, analyzes the basic state and failure of two kinds of pitch systems Mode and so on. Based on the analysis of the chainless towing system of the two kinds of pitch scraper conveyors, the design of larger pitch chainless towing system is put forward in the aspects of bending angle control, pitch control, pin tooth modification and matching clearance optimization. Provided some very useful suggestions.
