磨合试验中还发现了因齿面副两表面磨损率差形成的负电阻现象。
The negative oil film resistance is also found in the running-in, which results from the wear rate difference of the pair.
强调了齿面硬度、面粗糙度、滑情况、用前磨合情况等对齿轮接触强度的影响。
It also expounds influences of hardness and roughness of teeth surface, lubrication, running-in before use on touch strength of gear.
另外一方面，朋友见的磨合也会更加的好。
