Alien plug-in machines are selected by different enterprises or living places, which are more convenient for the public to use and improve quality. The pace of life and the promotion of social progress; When people encounter different problems during use, if the quality of the machine is not up to par, different risks will arise during use, which are related to the wear resistance and durability of the mechanical design.

The following details need to be noted:

① Avoid using the same material as the sliding friction pair

② Avoid using a white metal wear-resistant layer that is too thick

③ Avoid increasing the requirements for the entire part to improve the wear resistance of the part surface, avoid local wear of large parts, and prevent the entire part from being scrapped.

④ When using white metal as a component for bearing lining, pay attention to the selection of bearing lining material and bearing structure design, ensure sufficient supply of lubricating oil, and cover the working surface.

⑤ The lubricating oil tank should not be too small, and the filter should not filter out the additives in the lubricant.

⑥ The size, position, and shape of the sliding bearing oil groove should be reasonable, and lubricating grease should be avoided from being added to the rolling bearing.

⑦ Add a certain amount of wear allowance on the wearable surface of the component, and pay attention to adjusting it after the component wears out.

⑧ The contact surface with the same speed and pressure difference between the upper points should be small, and dust-proof devices should be used to prevent abrasive wear.

⑨ The characteristics of the irregular automatic insertion machine to avoid step wear are strong aiming force and special operating mode.
