The elimination method of rotary tiller out of gear

1. Common causes of rotary tiller out of gear

(1) rotary tiller stops when it reaches the specified torque. The tooth embedded clutch is used. Due to the long use time, the tooth embedded meshing surface is seriously worn, making the top of the meshing tooth bald and in a circular arc, losing the self-locking ability after meshing, and it is easy to slip and out of gear during operation

(2) the elastic force of the positioning spring of the meshing sleeve is too small or broken, the meshing teeth are forced or encounter the vibration of the unit, and the meshing sleeve produces axial sliding and disengages

(3) the axial wear of the directional steel ball groove of the meshing sleeve is large, and the steel ball generates axial swimming during the operation of the unit, which disengages the meshing teeth. Advanced sensors with other characteristics will also fly into ordinary people's homes

(4) the shift groove and the ball head of the control lever are excessively worn. Due to the excessive axial free clearance during the shift process, even if the gear is engaged, the meshing width of the meshing teeth is small, and it is easy to disengage in case of load change or unit jump

2. Troubleshooting of off gear fault

(1) when the clutch meshing teeth are worn out, they should be repaired or replaced in time. During repair, the meshing teeth can be overlaid with carbon copper welding rod, and then repaired with standard tooth indentation after welding, and heat treatment shall be carried out according to the regulations

(2) replace the spring with a standard spring that has too little or broken elasticity to ensure that the meshing sleeve has sufficient positioning stability and reliability

<1373p> (3) if the groove of the positioning steel ball of the meshing sleeve is excessively worn, it should be repaired or replaced with a new part

(4) when the retaining groove and the ball head of the control lever are excessively worn, they can be repaired by welding, and heat treatment can be carried out after manual repair. Replace with new parts that cannot be repaired. (does the shield wire of en sensor work d)
