There are many reasons for the failure of the roller needle bearing. All the factors affecting the design and manufacturing process will be related to the failure of the bearing, and it is difficult to judge by analysis. In general, it can be considered and analyzed in terms of both usage factors and internal factors. The use factors mainly refer to whether the installation adjustment, use and maintenance, maintenance and repair, etc. meet the technical requirements. The installation condition is one of the primary factors in the use factor. The bearing is often changed due to improper installation, and the force state between the parts of the whole bearing changes. The roller needle bearing runs in an abnormal state and fails early. According to the technical requirements of bearing installation, use, maintenance and maintenance, monitor and check the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation, find out the cause and immediately adjust the cause, make adjustment Back to normal. In addition, it is important to analyze the quality of the grease and the surrounding medium and atmosphere.
1. How to deal with the influence of excessive temperature of the roller needle bearing
(1). The alarm bell will ring.
(2). The machine side water wheel mechanical fault light plate is on, the temperature of the instrument indicating the bearing temperature rises, and the signal relay acts.
(3). Thermometer disk (inflated thermometer) The black needle and the yellow needle overlap or exceed the yellow needle.
(4). A fault signal that raises the temperature of the roller needle bearing.
2. Causes of high temperature bearing phenomenon:
(1). It may be that the cooling water of the bearing is interrupted, causing high temperature.
(2). It may be that the oil quality of the roller needle bearing is degraded, the oil itself is not clean or the oil is degraded during operation. If the water in the oil increases, it will cause the acid of the oil.
性增大，会降低油的润滑作用，使轴瓦遭到腐蚀，进而造成轴承温度升高的现象。
