There are many factors that affect the wear of automatic zipper threading machines, among which the most important factor is the assembly and installation quality of the automatic zipper threading head machine equipment.

The assembly quality of components has a significant impact on wear, especially clearance adjustment. If the gap is too small, it is not easy to form an oil film, resulting in high frictional heat, which can cause the friction pair to bite in severe cases. When the gap is too large, it is not easy to form an oil film, and impact, vibration, and noise exacerbate wear. For example, improper clearance between the piston rings of an internal combustion engine can cause piston oil leakage or piston ring damage to the cylinder liner.

If the components or machines of the same automatic zipper threading machine are not installed correctly, it can also cause impact, vibration, uneven load, eccentric wear, heat generation, noise, etc., resulting in premature wear of the zipper machine. For example, if the turbine unit, Roots blower, and other complete machines are not leveled or have a large coaxiality error with the motor shaft, it will exacerbate vibration and noise, damage the bearing oil film or increase temperature, and accelerate wear. In addition, the structure and motion properties of the motion pair can also affect the location of wear and the degree of uniform wear. Unreasonable design of parts can also exacerbate wear and tear, and so on.
