What are the causes and treatment measures of crack in cardan shaft?

There are generally two reasons for cardan shaft failure. One is that cracks at the fork head of cardan shaft accounted for 60% of the total faults. Second, the fracture of the spline sleeve of the cardan shaft accounts for 40% of the total faults. For the above reasons caused by cracks in the cardan shaft improvement measures generally have the following methods.



What are the causes and treatment measures of crack in cardan shaft?

1, the working reason: can be the crane truck track gauge levelness and height difference adjustment, the track port for thermite welding to improve the working environment.
2, the bearing is not uniform: the brake torque can be adjusted to make the 4 sets of brakes brake synchronously to prevent a single universal bearing from excessive torque.
3, processing technology: through the selection of cost-effective cardanes, from the material design and process to ensure quality at the source to reduce equipment failures caused by quality problems.
4. Model selection: Check and calculate the torque borne by the cardan shaft to verify whether the torque meets the requirements of use, which can ensure that the cardan shaft meets the actual requirements of use.
5, the cause of the universal shaft fracture, cracks in addition to the cause of bearing torque, and its product quality installation and bearing and working environment is also closely related.
For the cardan shaft due to the fork head slot cracks and spline sleeve fracture improvement method is the above content, we must pay more attention to protect the cardan shaft when using the corresponding line, cardan shaft once the fracture will have a great impact on the whole work.
