In recent years, to reduce vehicle emissions and improve vehicle fuel economy has become one of both the industry and the civil society are very focused on one topic. Therefore, manufacturers develop more efficient engines, motors, control more accurate, particularly in terms of exhaust gas circulation system and the electronic-valve design, engine exhaust system now has cut a lot of nitrogen oxide emissions than ever before.
However, install bearings in the engine parts will be subject to vibration or launch mount will cause bearing wear and reduce the service life. Therefore, NSK has recently launched a bearing wear and erosion resistance.
1. the optimization of bearing lubricating oil into the orbital plane. Even if the bearing is under harsh vibration environment, oil still flows into bearing well, compared with the current bearing, its degree of mechanical wear in vibration condition to reduce by half.
2. change the lubricant into the orbital plane, while the trace's properties unchanged, losses such as friction Seizure resistance and performance.
Bearing balls in the direction of the yellow arrow spinning, lubricants full passes to the pink area on the left side to the right, the ball was completely lubricant packages. However, engine reciprocating vibration occurs at run time, internal ball bearings also before and after vibration, when the ball when you scroll along the direction of the yellow arrow, pink ball and direct contact with the metal parts, mechanical wear is going to happen.
NSK new bearings lubricant into the orbital plane is optimized to prevent vibration of reciprocating engine ball when direct contact with the metal part. New bearing in vibration makes noise when halved compared to the previous generation, new bearing inner track surface remains smooth on the right side, who are currently using the bearing inner track surface suffered different degrees of wear and erosion.
