Three Major Causes Cause Weichai Generator Set Balance Shaft Breaks

Diesel generators as a whole are made up of many parts. It must be ensured that each part is in good condition for the normal operation of the diesel generator set. The following describes the cause of the fracture of the balance shaft of the Weichai generator set accessories to the user, so that the fault can be eliminated according to the reason when dealing with the failure of the unit. Specific content to look at the introduction of China Power!
1, bearing loose. The so-called balance shaft bearing loose, common causes of abnormal wear of the seat hole is due to poor engine balance, flow bearing operation is not flexible, the balance shaft at both ends of the hole coaxial concentricity, balance shaft axial clearance is too large. After the wear of the seat hole increases, the balance bearing is subjected to an excessive impact load, resulting in breakage of the balance shaft.
2, bad gear meshing. The axis of the balance shaft gear and the gear meshed therewith are equal to each other. The meshed gears are jammed in the transmission process, and the balance shaft is subjected to periodic bending stress, resulting in fatigue fracture of the balance shaft.
3, assembly error. In the process of disassembly and maintenance of diesel engines, the balance shaft is sometimes loaded incorrectly. For example, if the timing gear is installed, the timing mark is loaded incorrectly. At this time, the balance of the police not only can not play a balancing role, but will cause greater vibration, resulting in the balance of the shaft fracture.
The above three reasons have caused the fracture of the balance shaft of the Weichai generator set accessories. When using the diesel generator set, the user must pay attention to the inspection and maintenance of the generator set. Find out the cause of the abnormality of the generator set and eliminate the fault.
