AI Technical Summary
The existing rocker arm shaft suffers from poor lubrication due to lubricant adhesion during use, which affects normal operation.
Multiple through holes and a protective layer are provided on the rocker arm shaft. The through holes are designed to allow oil to enter from multiple directions. The protective layer is made of polyurethane and superhydrophobic coating, combined with a corrosion-resistant layer of epoxy resin and silicate coating to improve lubrication efficiency.
By combining a multi-hole design with a protective layer, lubricant adhesion is prevented, significantly improving lubrication efficiency.
