Cardan shaft

The rotor is connected to the upper part and the drive shaft is connected to the lower part. Its function is to convert the planetary motion of the rotor into the fixed shaft rotation of the drive shaft, and transmit the torque and speed of the motor to the drive shaft and the drill bit. It is a transitional connection between the rotor and the drive shaft. . After the drilling tool is used, it should be disassembled in time to check the wear of the universal joint shaft. If the wear is small, it can be used after maintenance. If the wear exceeds the maintenance standard, it should be replaced, and the incense will not work normally.
