我国的系列装载机结构卜大同小异，变速泵、转向泵和工作泵的两个驱动轴一般均由连接在变短器泵轮上的齿轮驱动。由于驱动轴轴承的位置较高，飞溅润滑条件很恶劣，轴承的使用寿命远远达不到设计要求。维修时要把变矩器与变速箱分开才能更换轴承，时间长且很麻烦。为延长轴承的? The structure of our series of loaders Bu Bu similar, variable speed pump, steering pump and working pump of the two drive shaft are generally connected to the shortening pump gear wheel driven. Due to the high position of the drive shaft bearings, splash lubrication conditions are very poor, the bearing life is far less than the design requirements. Maintenance should separate the torque converter and the gearbox to replace the bearing, a long time and a lot of trouble. To extend the bearing?
