The sliding bearing is in surface contact, so a certain oil film should be maintained between the contact surfaces. Therefore, the following problems should be noted in the design.
1Let the oil film enter the surface smoothly.
2The oil should enter the bearing from the non-bearing surface area.
3.Do not open the full ring oil groove in the middle of the bearing.
4.such as oil tiles, open the oil groove at the seam.
5.to make the oil ring to the oil is fully reliable.
6. Do not block the fuel hole.
7. Do not form a zone where oil does not flow.
8. Prevent sharp edges and corners from cutting off the oil film.
