There are many reasons for the gear skipping of excavators. In the frequent shifting process, the end face of each meshing gear is easy to be ground into a cone, which will cause its meshing performance to decrease and lead to "skipping"; the transmission of this type of excavator is made by mechanical manual shifting, such as transmission rod, longitudinal shaft, horizontal shaft and vertical shaft. Fixed screw loosening can also cause transmission "jump gear"; sudden changes in external load and improper operation, etc., Wuhan excavator lease analysis of how to prevent jump gear problem.

预防措施：

Preventive measures:

(1)严格按照操作规程和驾驶要领进行操作，尽量避免换挡时"打齿"，以减少齿轮副的磨损。

(1) Strictly follow the operating rules and driving essentials to operate, as far as possible to avoid shifting "teeth" to reduce gear wear.

(2)严格执行保养制度，加强换挡装置的维护保养。当换挡装置杆系连接不当时应及时调整，确保换挡装置性能良好。

(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)注重对自锁机构的维修与保养，对定位作用降低或失去定位效能的定位钢球、弹簧及拨叉轴，应及时修复或更换，使自锁机构的自锁性能处于良好的状态。

(3) Pay attention to the repair and maintenance of the self-locking mechanism, and repair or replace the positioning ball, spring and fork shaft in time, so that the self-locking performance of the self-locking mechanism is in good condition.

(4)组装变速器时，应严格按操作规程进行操作，确保变速器各机件调整正确、紧定适当。较大的下坡路面时，驾驶员应严格按照下坡的动作要领进行操作，切不可违规。

(4) When assembling a transmission, it should be operated in strict accordance with the operating rules to ensure that the transmission components are correctly adjusted and properly fixed. When a large downhill road surface, the driver should strictly follow the downhill action essentials to operate, must not violate the rules.

在挖掘机的行驶过程中，若出现变速器"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 driving, if the transmission "jump" occurs, the machine should be stopped in time, and then find the cause, troubleshooting. The specific methods are:

1.在平路上行驶时出现"跳挡"，可按正常的停机要领停机，认真查找原因，排除故障。

1. When running on a flat road, there is a "jump in gear", which can be stopped according to the normal stopping essentials, carefully find out the causes and troubleshooting.

2.在下坡道上行驶时出现"跳挡"，应按加挡的动作要领将挡位置于高-速的位置或采取"抢挡"措施，待机器行驶到坡底后再停机检查，排除故障；若"加挡"、"抢挡"不成功或又一次出现"跳挡"时，驾驶员可将发动机转速控制在中速，采用"点刹"的方法使机器滑坡底，然后排除故障。

2. When "jumping gear" occurs on the downhill, the driver can control the engine speed at the middle speed if the "shifting gear" and "snatching gear" are unsuccessful or another "jumping gear" occurs. The "point brake" method is used to slide the machine to

the bottom of the slope, and then remove the trouble.

3.上坡行驶时出现"跳挡"，可将挡位置于低-速位置或Ⅰ挡位置，待机器行驶到坡顶时再停机，排除故障；若减挡不成功或又一次出现"跳挡"时，应按坡道停机的动作要领及要求停机，然后排除故障。

3. Uphill driving when there is a "jump gear", can be in the low-speed position or the first gear position, when the machine is driving to the top of the hill again stop, troubleshooting; if the gear reduction is not successful or another "jump" occurs, should stop according to the ramp stop action and requirements, and then troubleshooting.
