There are many factors that affect the mechanical wear of zippers machinery:
the most important of which is the quality of assembly and installation of the zippers.
The assembly quality of parts has a great effect on wear, especially clearance adjustment. If the gap is too small, it is not easy to form an oil film, and high frictional heat is generated, which can cause the friction pair to bite in severe cases. When the gap is too large, it is difficult to form an oil film, and shock, vibration, and noise increase wear. Another example is the improper clearance of the piston ring ring of the internal combustion engine, which may cause the oil leakage of the piston or the cylinder ring may damage the cylinder liner.
Similarly, if the assembled components or machines of the zipper machinery and equipment are incorrectly installed, they will also cause shock, vibration, uneven load, uneven wear, heat, and noise of the machine, causing premature wear of the zipper machine.
For example, turbines, Roots fans, etc. If the whole machine is not leveled or the coaxiality with the motor shaft is too large, vibration and noise will be exacerbated, the bearing oil film will be damaged or the temperature will be increased, which will accelerate the wear. In addition, the structure and nature of the motion pair will also affect the worn parts and the uniform degree of wear. Inappropriate design of part shape will also increase wear and so on.
Only by understanding the influence of various factors on wear and taking corresponding measures can we effectively reduce wear and extend the service life of zipper machines.
