Rotary cultivator off how to do?

1. The claw-type clutch is used in the rotary cultivator. Due to the long time used, the meshing surfaces of the teeth are severely worn, making the tooth-toothed tooth teeth become arc-shaped and losing the ability to lock after meshing. The process slips easily and it disengages. Second, the engagement sleeve positioning spring is too small or broken, the meshing teeth are subjected to force or the vibration of the unit, and the engagement sleeve generates an axial slip and is released. 3. The directional steel ball groove of the engaging sleeve wears large in the axial direction. During the working process of the unit, the steel ball generates axial movement and the meshing teeth are disengaged. Four, the dial groove and the joystick ball head excessive wear, due to the axial free clearance is too large during the shift process, even if the upper gear is engaged, the engagement width of the meshing teeth is also small, it is easy to take off when the load changes or the unit jumps block. Troubleshooting method First, when the clutch meshing teeth are bald, they should be promptly repaired or replaced. The repair can be used carbon welding electrode welding meshing teeth, and then using standard tooth indentation after welding repair, and heat treatment according to the provisions. Second, use a standard spring to replace the spring with too little elasticity or broken to ensure that the engaging sleeve has sufficient positioning stability and reliability. Third, the engagement sleeve positioning steel ball groove if excessive wear, should be repaired or replaced with new parts. Fourth, the dial groove and the joystick ball head can be repaired when excessive wear, after manual repair and heat treatment. Replacement of new parts that cannot be repaired.
