2、 Structural design to improve wear resistance（Problems needing attention in mold design of 500 cases）

1. Avoid matching the same materials into sliding friction pairs
2. Avoid excessive thickness of white alloy wear-resistant layer
3. Avoid increasing the requirements for the entire part to improve the wear resistance of the part surface
4. Avoid partial wear of large parts leading to scrapping of the entire part
When using white alloy as bearing liner, attention should be paid to the selection of bearing pad materials and the structural design of bearing pads
6. Sufficient lubricant supply, full of working surface
7. The lubricating oil tank cannot be too small
8. Do not allow the filter to filter out additives from the lubricant
The size, position, and shape of the oil groove of the sliding bearing should be reasonable
The amount of lubricating grease added to the rolling bearing should not be excessive
11. Add a certain wear allowance to the easily worn surface of the parts
12. Pay attention to the adjustment after wear of parts
13. The speed and pressure differences between points on the same contact surface should be small
14. Use a dustproof device to prevent abrasive wear
15. Avoid formation of step wear
16. Sliding bearings cannot use contact oil seals
17. Protect the easily worn parts
18. The structure of automatic compensation for wear and tear can be adopted for easily worn parts
