Since the cardan shaft is the most used mechanical part at present, in order to ensure the safety of installation, it is necessary to measure and adjust. The method of measuring the out-of-center coupling with a knife ruler and feeler gauge is suitable for low-speed equipment and elastic joints without precision requirements. .This method is suitable for equipment with fast rotation speed, rigidity combination and high precision. Overheating or flattening of the cardan shaft during operation will cause the surface mechanical properties to change and damage.
This type of damage uses tools and other machinery. The grinding disc and other machinery determine the surface hardness. It can be observed that the workpiece is crushed. When these defects exist, even if the workpiece or size does not exceed the allowable wear range, it will be affected by the mechanical properties of the surface. Change and reject the workpiece, and its static press-in method is restricted by the pressure machine, so when the workpiece or the size is too large, it is difficult to apply a large force. At the same time, during the press-in process, the joint surface between the universal shafts will appear Uneven small peaks, cracks in the joint surface, causing damage to the workpiece or size.
The installation method of the universal joint shaft should be determined as far as possible. When there are certain requirements, the angle of the axis must be inclined and the horizontal and vertical angles must be determined. Impact tools and mechanical tools are used during the assembly process, which are generally used for the transitional fit and transition of the universal joint shaft. In the case of a small surplus, at the assembly site, a hammer is usually used to hit the end surface of the wheel hub with a wooden block, or use other soft materials as a buffer material, and hit the coupling with the impact of the hammer.
The cardan shaft of the wheel can be simply installed on the shaft. The heating method is used to thermally expand the cardan shaft, the cooling method is used to thermally expand the cardan shaft, the temperature difference assembly method is used for heating, the cooling method is used for cooling, and the advantages of the assembly method are adopted. It plays an assembly role and does not match the main shaft of the cardan shaft. The anti-rust oil must be cleaned during assembly.
