履带式推土机张紧装置内设有大型张紧弹簧总成,通过该张紧弹簧总成的弹力推动引导轮将履带张紧,还可吸收地面传过来的冲击和振动,起到缓冲作用。将该张紧弹簧总成安装至张紧装置之前,需对其弹簧进行压缩,方可安装。该弹簧安装后需具有适宜的预紧力,才能将履带张紧。为了保证张紧弹簧总成压装质量、提高压装效率,使压装工作安全可靠,我们设计了推土机张紧弹簧总成专用压装工具。1.张紧弹簧总成结构推土机的张紧弹簧总成由后法兰盘1、螺母2、张紧杆3、弹簧4、前法兰
A large tension spring assembly is installed in the crawler dozer tensioning device. The tensioning spring assembly pushes the guide wheel to tension the crawler belt, and can also absorb shocks and vibrations transmitted from the ground to cushion the crawler bulldozer. Before installing the tension spring assembly to the tensioner, its spring needs to be compressed before it can be installed. The spring must be fitted with a suitable pre-tightening force to tighten the track. In order to ensure the loading quality of the tension spring assembly, improve the loading efficiency, and make the loading work safe and reliable, we designed the special pressing tool for the bulldozer tension spring assembly. 1.
