The universal joint does not change. In fact, the relationship between the universal joint and the universal joint is not large. The main reason is that the universal joint caused by other problems does not change. Generally, there are four reasons:
The power output is out of gear and the gear is not in place.
If the power output is out of gear and the gear is not in place, the power output and the universal joint will not rotate. In actual work, the power output is out of gear, which is caused by gear wear, large clearance, small self-locking spring pressure, etc. The deformation of the fork is easy to cause the gear to be out of position, the gear is not in place, and the load will be large. Disconnected.
Power output front axle, or power output rear axle break
Power output shaft breakage is one of the most common faults on tractors. Most tractor power output is now two-and-a-half with external flanges for easy maintenance. Commonly, the power output of the flange has a broken half shaft. There is also a power output front half shaft broken, the power output shaft is broken, and the universal joint will not turn.
The power output drive shaft is broken or the connecting sleeve is detached.
The power output transmission shaft is installed in the gearbox and the rear axle. The phenomenon that the power output transmission shaft is broken and the connecting sleeve between the power output transmission shafts is detached is rare. Occasionally, the actual maintenance has been encountered several times. The universal joint will not turn.
Vice clutch slippery
The sub-clutch slippery burnt film is also a common fault on the tractor. Since the sub-clutch is not adjusted or the load is too large, the sub-clutch will slip and burn during use, and the universal joint will not turn.
Power output driving agricultural machinery is one of the most widely used forms of tractors, but it is also the part with the highest failure rate and the most headaches for users and dealers. It often has unreasonable matching, low work efficiency and poor operation. A series of faults, such as not entering the soil, pulling, and power output shaft break, make the tractor manufacturers and the service personnel of the engine manufacturers supporting the tractor have a headache.
