The quality of lubricating oil is very important for needle roller bearings. In addition, when a hybrid vehicle (HEV only uses a motor), the oil pump sometimes does not operate, causing the thrust needle roller bearings for the gearbox to be used in an environment with insufficient lubricating oil, which will also damage the washers.The working efficiency of needle roller bearings in normal operation is related to many factors.
To improve transmission efficiency, use lubricating oil with low viscosity. There are many factors such as the quality of the lubricating oil purchased and the poor lubrication effect. Changzhou Youcheng Bearing found that the effect of using long-life bearing washers is much more convenient than lubricating oil. If the viscosity is low, it is difficult to form an oil film between the roller and the washer.
In this way, the roller will slide and make metal contact with the washer, which will quickly break the washer. It uses multi-stage AT in order to reduce stirring resistance, in order to improve fuel efficiency, reduce variable speed China Clutch Release Bearings factory vibration and improve power transmission efficiency. When the machine is running, the friction force of the contact surface of the needle roller bearing becomes smaller, reducing its surface wear and prolonging its service life, but the long-term use of lubricating oil will also have a certain degree For example, the lubricating oil will fail after being used for a long time and cannot play the role of lubrication.
Needle roller bearings use a pressure ring to avoid The direct contact of the bearing surface during the working process reduces the surface wear and extends its service life to the maximum extent. Lubricating oil can play a role in lubrication
