There are many reasons for the excavator's skipping. In the frequent shifting process, the end face of each meshing gear is easily ground into a cone, which will cause the meshing performance to decline and lead to "skipping". The mechanical manual shifting mode is chosen for the transmission of the excavator when the gearshift is not properly installed and adjusted, and the "skipping" of the transmission can also be caused by the loosening of the transmission rod, the longitudinal axis, the horizontal axis and the vertical fixed screw. With the sudden change of external load and improper operation, how to prevent the problem of gear jump in Wuhan excavator leasing analysis?

　　防备办法：

　　Preventive measures:

　　(1)严厉依照操作规程和驾驶方法进行操作，尽量防止换挡时"打齿"，以减少齿轮副的磨损。

　　(1) Operate strictly in accordance with operating rules and driving methods, and try to prevent "teeth beating" when shifting, so as to reduce the wear and tear of gear pairs.

　　(2)严厉执行保养制度，加强换挡设备的维护保养。当换挡设备杆系连接不妥时应及时调整，保证换挡设备性能良好。

　　(2) Strictly enforce the maintenance system and strengthen the maintenance of gear shifting equipment. When the link system of gear shifting equipment is not properly connected, it should be adjusted in time to ensure good performance of gear shifting equipment.

　　(3)注重对自锁机构的维修与保养，对定位作用下降或失掉定位效能的定位钢球、绷簧及拨叉轴，应及时修正或替换，使自锁机构的自锁性能处于良好的状态。

　　(3) Attention should be paid to the maintenance of self-locking mechanism. The positioning steel balls, tension springs and fork shafts which reduce or lose positioning efficiency under positioning should be corrected or replaced in time to make the self-locking performance of self-locking mechanism in a good state.

　　(4)拼装变速器时，应严厉按操作规程进行操作，保证变速器各机件调整正确、紧定恰当。较大的下坡路面时，驾驶员应严厉依照下坡的动作方法进行操作，切不可违规。

　　(4) When assembling transmission, strict operation should be carried out according to the operating rules to ensure that the adjustment of various parts of transmission is correct and proper. When a large downhill road surface, the driver should strictly follow the downhill operation method, and must not violate the rules.

　　在挖掘机的行进过程中，若呈现变速器"跳挡"时，应及时使机器停机，然后查找原因，排除故障。具体方法是：

　　In the course of excavator's running, if the transmission "jumps", it should stop the machine in time, and then find out the cause, and troubleshoot. Specific methods are as follows:

　　1.在平路上行进时呈现"跳挡"，可按正常的停机方法停机，仔细查找原因，排除故障。

　　1. When traveling on the flat road, it appears "jump gear", which can be stopped according to the normal method of stopping, carefully find out the reasons and troubleshoot.

　　2.鄙人坡道上行进时呈现"跳挡"，应按加挡的动作方法将挡方位于高-速的方位或采取"抢挡"办法，待机器行进到坡底后再停机查看，排除故障；若"加挡"、"抢挡"不成功或又一次呈现"跳挡"时，驾驶员可将发动机转速控制在中速，选用"点刹"的方法使机器滑坡底，然后排除故障。

　　2. When running on the ramp, the driver can control the speed of the engine at medium speed and use the method of "point brake" to make the machine slide to the bottom of the ramp if the "step-up" and "scramble" are unsuccessful or when the "jump-off" occurs again, then the driver can control the speed of the engine at medium speed and use the method of "point brake" to make the machine slide to the bottom of the ramp. After troubleshooting.

　　3.上坡行进时呈现"跳挡"，可将挡方位于低-速方位或Ⅰ挡方位，待机器行进到坡顶时再停机，排除故障；若减挡不成功或又一次呈现"跳挡"时，应按坡道停机的动作方法及要求停机，然后排除故障。

　　3. Uphill travel presents "jump gear", which can stop at low-speed or I-stop position until the machine moves to the top of the slope to eliminate the malfunction. If the gear reduction is unsuccessful or the "jump gear" appears again, it should stop according to the action method and requirement of ramp stop, and then eliminate the malfunction.
