主卷扬减速机是工程机械常用的传动装置,主要用于履带式起重机、履带式强夯机、履带式旋挖钻机的起升机构上。主卷扬减速机多采用多级行星减速机构,具有传动速比大、传递扭矩大等特点。如设有离合器,可实现空钩快放功能,有效提高其工作效率。本文主要针对液压履带式强夯机所采用的主卷扬减速机常见故障进行分析。1.组成及工作原理应用于某型液压履带式强夯机上的主卷扬减速机主要由液压马达1、平衡阀
Main winch reducer is a common construction machinery transmission, mainly used in crawler cranes, crawler tamping machines, crawler rotary drilling rig lifting mechanism. The main winch reducer multi-stage planetary reduction gear, with transmission speed ratio, transmission torque and so on. If equipped with a clutch, can achieve empty hook quick release function, effectively improve their work efficiency. This paper mainly analyzes the common failures of the main winch reducer adopted by hydraulic crawler tamping machine. 1. Composition and working principle Applied to a hydraulic crawler tamping machine main winch reducer mainly by the hydraulic motor 1, balance valve
