4 Reasons for Machine Parts Failure
The failure of a machine part is a phenomenon in which the size, shape, or organization, and performance of the material are changed due to some reasons, and the specified function is lost. We need to find the reasons for the failure of machine parts and then deal with them in time to prevent the machine from malfunctioning during operation. The following are the four common causes of machine parts failure.
Unreasonable part design
The unreasonable structure, shape, and size design of machine parts are most likely to cause failure. Such as keyways, holes or sharp corners, or sharp nicks where the cross-section changes are prone to stress concentration and cracks. Secondly, it is wrong to judge the force condition of the parts at work, and the design is unreasonable, such as the safety factor is too small or the environmental change is underestimated, and the actual bearing capacity of the parts is reduced.
Unreasonable selection of materials
Unreasonable material selection means that the performance of the selected material cannot meet the requirements of the working conditions, or the nominal performance index of the selected material cannot reflect the resistance of the material to the actual failure mode. The unreasonable chemical composition and organization of the materials used, and poor quality will also cause the failure of the parts, such as containing too many inclusions and impurity elements and other defects. Therefore, a strict inspection of raw materials is an important step to avoid precious machine parts failure.
Unreasonable processing technology
In the process of processing and forming, machine basic parts will fail due to unreasonable process methods, process parameters, and incorrect operations. For example, overheating, overburning, oxidation, and decarburization caused by excessively high temperature in the hot forming process; deformation and cracks caused by unreasonable process parameters in the heat treatment process, structural defects, and corners, steps, etc. of parts due to uneven quenching stress Generate tensile stress.
Incorrect installation and use
During the installation of the machine, if the fit is too tight, too loose, poorly aligned, not firmly fixed or center of gravity is not stable, poor sealing, too much or too little force during assembly and tightening, etc., will easily lead to premature failure of machine parts. Working under excessive speed, overload, poor lubrication conditions, corrosive substances in the working environment, and untimely or improper repairs and maintenance will cause premature failure of parts.
