it is not a strange thing to pick up gear in a excavator transmission, and it is not an unprovoked occurrence. so today, we have brought about the reasons for the excavator to pick up the gear.
(1) because of improper adjustment, the transmission of this type of excavator adopts a mechanical type of manual shift. if the loosening of the gearshift lever, the longitudinal axis, the horizontal axis and the vertical fixed screws is also likely to cause the gearshift of the transmission.
(2) the driving mechanism of the mechanical gear shift is mainly used on the excavator. this kind of transmission mechanism relies on the sliding gear sleeve to move axially on the fixed gear sleeve and meshes with the driven gear of each gear to achieve the purpose of shifting. of course, in the frequent shift process, the teeth of the gear teeth are very easy to be grinded into conical state, causing its meshing performance to reduce too fast and lead to "jump gear".
(3) if the operator operates improperly and makes the excavator run on the ramp, the transmission trip will happen.
the above is about the cause of the gear shifting of the excavator, and i hope it will help the operators in daily work.
