一、跑偏产生的影响履带式起重、挖掘机行走跑偏(履带行走轨迹不与机身纵向中心线平行),产生的水平侧向分力增加发动机的负荷,增大油耗,降低经济性能,增加磨损,加剧机械的损坏,严重的时候还出现履带啃轨。在上下平板拖车的时候,由于履带跑偏,会使其从跳板上翻下来,造成重大事故。二、跑偏的原因 1.驱动轮或引导轮的水平偏斜履带的驱动轮或引导轮的安装偏差,引起驱动轮或引导轮的水平偏斜,此时起重、挖掘机前进或后退,偏斜的轮子使两履带板产生夹角造成跑偏。
First, the impact of running deviation Track-type lifting, excavator walking deviation (track walking trajectory is not parallel with the longitudinal centerline of the fuselage), the resulting horizontal lateral component force to increase the engine load, increase fuel consumption, reduce economic performance , Increased wear and tear, increased mechanical damage, and crawler rails appeared in severe cases. When the flatbed trailer is raked up and down, the crawler will be turned off due to the deviation of the crawler, causing a major accident. Second, the cause of deviation 1. Driving wheel or guide wheel horizontal deflection track drive wheel or guide wheel installation error, causing the drive wheel or guide wheel horizontal deflection, this time lifting, excavator forward or backward, The skewed wheels cause the two track shoes to generate an angle and cause a deviation.
