  挖掘机是一种非通有数的工程呆板,“移位”是挖掘机的有数拦阻之一,在挖掘机的驱动进程中,要是传动“移位”,应及时停机(或延续运转),然后查找缘故缘故原因,扫除拦阻。下面过细阐发了挖掘机“移位”的缘故缘故原因,以及处置处分要领:
  Excavator is a very common construction machinery, "displacement" is one of the common faults of excavator. In the driving process of excavator, if the transmission "shifts", it should be stopped (or continue to run), and then find out the reason, and eliminate the fault. The following detailed analysis of the excavator "shift" reasons, as well as the handling methods:
  1. “跳闸”的缘故缘故原因
  1. Cause of "trip"
  (1)遵从的自锁机制来防范“跳出”的转达,转达的模范挖掘机Ⅱ、Ⅲ封面和ⅣⅤ叉轴顶部的盒子盖内孔和Ⅰ,反向齿轮叉自锁安钢球和弹簧的作用。当自锁弹簧弹性削弱或断裂时,自锁机构的自锁遵从下降直至流失,招致传动“跳变”。同时,定位的钢球或叉轴槽如有磨损,也会构成变速器的“跳档”。
  (1) Performance of self-locking mechanism to prevent the "jump out" of the propagation, the propagation type of excavator II, III cover and IV V fork shaft top box cover inner hole and I, reverse gear fork self-locking steel ball and spring. When the elasticity of the self-locking spring is weakened or broken, the self-locking performance of the self-locking mechanism decreases until it disappears, resulting in the "jump" of the transmission. At the same time, if the positioning steel ball or fork shaft groove is worn, it will also cause the "shift skipping" of the transmission.
  (2) w4-60挖掘机的换档传动机构磨损是呆板换档的传动机构,它寄予壮实齿轮套上的滑动齿轮套举行轴向活动,并与各块从动齿轮啮合完成换档。在频繁换档的进程中,上述啮合齿轮的齿轮齿端面很容易磨成圆锥,招致其啮合遵从下降,孕育发生“跳齿轮”。
  (2) The gearshift transmission mechanism wear of w4-60 excavator is a mechanical gearshift transmission mechanism. It relies on the sliding gear sleeve on the fixed gear sleeve for axial movement, and meshing with each driven gear to achieve the gearshift. In the process of frequent shifting, the gear tooth end face of the meshing gear is easy to grind into a cone, resulting in its meshing performance degradation and "gear skipping".
  (3)外载荷的突变由于挖掘机的变乱性子和挖掘机自身的设计,外载荷的突变也会招致其传动装置“跳档”。当路面凸凹,呆板下坡行驶约莫开车路线不当,使外部负载突然改造,负载的突然改造会颠末轮,传动装置的传动轴方法啮合齿轮,齿轮啮合的轴向推力的孕育发生,招致传输“跳块”。
  (3) The sudden change of external load is due to the working nature of excavator and the design of excavator itself, and the sudden change of external load will also lead to the "jump gear" of its transmission device. When the road surface is convex or concave, the machine goes downhill or the driving route is improper, so that the external load changes suddenly, the sudden change of load will move through the wheel, the transmission shaft of the transmission device to engage the gear, and the axial thrust of the gear mesh will be generated, resulting in the transmission "jumping block".
  (4)变速装置调停不当这种模范的挖掘机的传动采取呆板手动变速要领,要是变速杆、纵轴、横轴和垂直壮实螺钉松动也会招致传动“变速”。
  (4) The transmission of this type of excavator adopts mechanical manual transmission mode. If the transmission lever, longitudinal axis, transverse axis and vertical fixed screw are loose, the transmission will also "shift".
  (5)应用不当的挖掘机在坡道下行驶(尤其是下坡行驶),要是应用不当,还会招致变速器“跳挡”。
  (5) Improper operation of the excavator on a ramp (especially downhill driving), if not properly operated, will also cause the transmission to "jump".
  2. 应急要领
  2. Emergency methods
  在挖掘机的驱动进程中,要是传动“跳块”,应及时停机(或延续运转),然后查找缘故缘故原因,扫除拦阻。细致要拥有:
  During the driving process of the excavator, if the transmission "bumps", stop the machine in time (or continue to run), then find out the cause and eliminate the fault. The specific methods are as follows:
  (1)有一个“跳出”希尔路,可以陈设在位置或块Ⅰ块位置,低速率呆板停机时间再次去顶部时,拦阻扫除;要是减块不可功或出现另一个“跳块”,则应依据方法要点和关秘密求抑制斜坡,然落伍行拦阻扫除。
  (1) There is a "jump" Hill Road, which can be placed in the position or block I position. When the low-speed machine goes to the top again after the shutdown time, the fault can be eliminated; if the block reduction is not successful or another "jump block" occurs, the slope shall be stopped according to the action points and shutdown requirements, and then the fault can be eliminated.
  (2)平路行驶时若出现“跳车”,可按正常停车点停车,查找缘故缘故原因,扫除拦阻。
  (2) If "trip" occurs when driving on a flat road, you can stop at the normal stop point, find out the cause and eliminate the fault.
  (3)在下坡行驶时如有“跳块”,请依据加块方法将其高速陈设,或采取“抓块”(告急停车)步伐。开到坡底后停机查抄,扫除拦阻;要是“添加块”,“抓块”不可功或再次出现“跳块”(中性)这个时间,司机可以控制倡议机转速在中心速率(以防范倡议机),运用“刹车”的要领使呆板滑动斜坡的底部,然后拦阻扫除。要是“添加块”,“抓块”不可功或“跳块”(这个时间它是中性的)再次发生,和下一个大斜坡的呆板(这个时间呆板将很快速率斜率“潜水”)的底部,应该快速的下坡抑制方法的紧张见地和抑制,然后扣除的错。
  (3) If there is "jumping block" when driving downhill, please place it at high speed according to adding block action, or take "grabbing block" (emergency stop) measures. After driving to the bottom of the slope, stop the machine for inspection and troubleshooting; if the "add block", "grab block" is not successful or "skip block" (neutral) occurs again, the driver can control the engine speed at the middle speed (to prevent the engine), use the "brake" method to make the machine slide the bottom of the slope, and then troubleshooting. If "add block", "grab block" is not successful or "jump block" (it is neutral at this time) occurs again, and the bottom of the next machine with a large slope (at this time, the machine will quickly "dive" the slope), the main point of view and stop of the action should be stopped quickly downhill, and then the error should be deducted.
