沥青洒布车是黑色路面筑路工程及养护工程施工过程中必不可少的专用设备。目前,我国黑色路面筑养路工程施工中最普遍使用的是LS—3500型沥青洒布车。该车的关键部件齿轮沥青泵直接影响整车的作业性能,而泵内工作齿轮副的加工质量好否是直接影响沥青泵性能的重要因素,由此可见,这一齿轮副(如图一)则是该沥青洒布车的关键件。 Asphalt spreader is pavement construction and maintenance of black road construction essential essential equipment. At present, the construction of China’s black pavement construction road is the most commonly used LS-3500-type asphalt distributor. The key components of the vehicle gear asphalt pump directly affect the performance of the vehicle operation, and the working pump gear pump quality is good or not directly affect the performance of asphalt pump an important factor, we can see that this gear pair (Figure 1) It is the key parts of the asphalt distributor.
