1.改进原因振动压路机进行振动碾压施工时,其振动轮内支撑偏心轴的轴承,在振动马达的带动下与偏心轴一起高速旋转,使偏心轴产生高频振动,从而带动振动轮产生振动效果。在振动轮振动过程中,其偏心轴轴承不但承受高频振动产生的径向压力,还承受摩擦产生的高温。目前,振动压路机经常出现振动轮偏心轴轴承损坏故障。经研究发现,振动轮偏心轴轴承采用的幅板流挂润滑方式存在问题。这种润滑方式原理如下:在振动轮转动时,储存在振动轮内部的润滑油被甩到振动轮体中部幅板上。流
1. Improvement reasons Vibratory roller vibration crushing construction, the vibration wheel bearing eccentric shaft bearings, driven by the vibration motor with the eccentric shaft together with high-speed rotation, the eccentric shaft to produce high-frequency vibration, which led to the vibration wheel vibration effect. In the vibration wheel vibration process, the eccentric shaft bearing not only withstand the radial pressure generated by high-frequency vibration, but also to withstand the high temperature generated by friction. At present, the vibration roller eccentric shaft bearing damage often appear fault. The study found that the vibrating wheel eccentric shaft bearing shedding lubrication problems exist. The lubrication principle is as follows: During the rotation of the vibrating wheel, the lubricating oil stored inside the vibrating wheel is thrown onto the middle plate of the vibrating wheel body. flow
