我厂老产品T_2-120A型推土机在使用中,经常出现履带张紧油缸严重变形现象。为此,在试制T120推土机时,我们对相关结构进行了改进。改进后的履带张紧油缸,在T120推土机上经过2000多小时的工业性试验,使用情况良好。但是,在T120推土机的变形产品TS 120湿地推土机样机工业性试验中,又出现履带张紧油缸严重变形问题。为了剖析张紧油缸变形原因,我们对履带张紧油缸的受力情况重新作了一些简单试验和
When the T_2-120A bulldozer of our factory’s old product is in use, there are often serious deformation phenomena of the track tensioning cylinder. For this reason, we improved the related structure during the trial production of the T120 bulldozer. The improved crawler tensioning cylinders have been used in T120 bulldozers for more than 2,000 hours of industrial trials and are in good condition. However, in the industrial trial of the TS 120 wetland bulldozer prototype of the T120 bulldozer’s deformation product, serious strain problems of the crawler tensioning cylinder occurred. In order to analyze the cause of the deformation of the tension cylinder, we re-created some simple tests on the force conditions of the track tension cylinder.
