推土机松土器齿杆的制造工艺,对其性能影响很大。若工艺不当,会引起齿杆断裂,从而影响推土机正常作业。针对市场反馈的某型推土机松土器齿杆经常出现断裂问题,我们开发出一种齿杆制造新工艺,大大提高了齿杆的使用寿命。1.旧工艺的缺陷松土器齿杆结构如图1所示。按照旧工艺制造出的齿杆,其断裂位置集中在 Bulldozer ripper gear manufacturing process, a great impact on its performance. If improper technology, will cause the gear rod fracture, thus affecting bulldozer normal operation. According to the market feedback of a bulldozer riprap often appear fracture, we have developed a new manufacturing process of gear, greatly improving the service life of the gear rack. 1. Defects of the old ripod shank structure shown in Figure 1. In accordance with the old process to create the tooth bar, the fracture location focused on
