汽车起重机取力器中间轴在使用中发生轴向定位失效,紧固螺栓断,挡圈、垫圈掉入齿轮箱,中间轴窜出,齿轮失去支承,从而造成取力器齿轮挤伤、壳体断裂,其中一台还损坏了下车JN150黄河牌汽车的变速箱。现将对这一事故的分析、处理情况,介绍如下。一、原构结简介原8吨液压汽车起重机取力器中间轴轴向定位原结构见图1。取力器安装在变速箱
In the use of the intermediate shaft of the power take-off of the truck crane, the axial positioning fails, the fastening bolt breaks, the retaining ring and the washer fall into the gear box, the intermediate shaft is pulled out, and the gear loses the support, thereby causing the power take-off gear to crush, the casing In the break, one of them also damaged the gearbox of the JN150 Yellow River vehicle. The analysis and handling of this accident will be introduced as follows. First, the original structure of the original 8 tons of hydraulic truck crane power take-off intermediate shaft axial positioning of the original structure shown in Figure 1. Power take-off mounted on gearbox
