        挖掘機跳擋的怎么預防?

        日期:2018-06-07   來源:http://www.qxngd.com/
        挖掘機跳擋的原因很多,在在頻繁的換擋過程中,各嚙合齒輪的輪齒端面易被磨成錐形,會造成其嚙合性能降低而導致"跳擋";換擋裝配調整不當該型挖掘機的變速器采用的是機械式人力換擋的方式,若變速桿、縱軸、橫軸及豎固定螺釘松動亦可造成變速器"跳擋";外界負載的忽然變化以及操作不當等等。
        There are many reasons for the jump of the excavator. In the process of frequent shift, the end face of the gear teeth of each gear is easily grinded to conical, which will cause its meshing performance to be reduced and cause "jump gear". The loosening of the fixed screw can also cause the "jump gear" of the transmission, sudden changes in the external load and improper operation.
        預防措施:
        Preventive measures:
        (1)嚴格按照操作規程和駕駛要領進行操作,盡量避免換擋時"打齒",以減少齒輪副的磨損。
        (1) operate strictly according to the operating rules and driving points, try to avoid "gear" when shifting gears, so as to reduce the wear of gear pairs.
        (2)嚴格執行保養制度,加強換擋裝置的維護保養。當換擋裝置桿系連接不當時應及時調整,確保換擋裝置性能良好。
        (2) strictly implement the maintenance system and strengthen the maintenance of shift devices. When the linkage of the shift device is not connected, it should be adjusted in time to ensure the performance of the shift device is good.

        (3)注重對自鎖機構的維修與保養,對定位作用降低或失去定位效能的定位鋼球、彈簧及撥叉軸,應及時修復或更換,使自鎖機構的自鎖性能處于良好的狀態。
        (3) pay attention to the maintenance and maintenance of self locking mechanism. The positioning steel ball, spring and fork shaft should be repaired or replaced in time to reduce or lose the positioning efficiency, so that the self locking performance of the self locking mechanism is in good condition.
        (4)組裝變速器時,應嚴格按操作規程進行操作,確保變速器各機件調整正確、緊定適當。較大的下坡路面時,駕駛員應嚴格按照下坡的動作要領進行操作,切不可違規。
        (4) when assembling the transmission, it should be strictly operated according to the operation rules to ensure that the transmission parts are adjusted correctly and properly. When the downhill road is larger, drivers should operate strictly according to the action points of downhill operation.
        在挖掘機的行駛過程中,若出現變速器"跳擋"時,應及時使機器停機,然后查找原因,排除故障。具體方法是:
        In the process of excavator driving, if there is a transmission "jump gear", the machine should be stopped in time, then the cause can be found out and the trouble is eliminated. The specific methods are:
        1.在平路上行駛時出現"跳擋",可按正常的停機要領停機,認真查找原因,排除故障。
        1. when running on a flat road, there is a "jumping gear", which can be shut down according to the normal stop points.
        2.在下坡道上行駛時出現"跳擋",應按加擋的動作要領將擋位置于高-速的位置或采取"搶擋"措施,待機器行駛到坡底后再停機檢查,排除故障;若"加擋"、"搶擋"不成功或又一次出現"跳擋"時,駕駛員可將發動機轉速控制在中速,采用"點剎"的方法使機器滑至坡底,然后排除故障。
        2. when driving on the lower ramp, "jump gear" should be appeared, and the position of the block should be placed in the position of high speed or "grab gear", and the machine will stop checking after the machine runs to the bottom of the slope, and then the fault is eliminated. If the "block", "grab block" fail or "jump" again, the driver can control the engine speed at medium speed. The "point brake" method is used to slide the machine to the bottom of the slope, and then remove the trouble.
        3.上坡行駛時出現"跳擋",可將擋位置于低-速位置或Ⅰ擋位置,待機器行駛到坡頂時再停機,排除故障;若減擋不成功或又一次出現"跳擋"時,應按坡道停機的動作要領及要求停機,然后排除故障。
        3. jump on the slope, "jump gear", can be placed in low speed position or I gear position, when the machine runs to the top of the slope, and then stop, troubleshooting, if the gear is not successful or once again "jump gear", should be shut down on the ramp and request stop, and then discharge fault.
