In the bearing work, heating is a common problem, and there are many factors that cause the high temperature of the outer spherical bearing. Relatively speaking, there are mainly the following five kinds of common heating. After understanding the different factors that cause the outer spherical bearing to heat up, you need to prescribe the right medicine. To completely eliminate the danger of the high temperature of the outer spherical bearing, the corresponding solution is also inevitable.
1. Response to the life span of the outer spherical bearing
Because the bones and raceways are absolutely invaded by moving and purified dust, the bones and raceways are worn out. When the amount of wear is large, the bearing, noise, and vibration increase, which increases the operating precision of the bearing, which indirectly reflects the precision of some long-term machines. Therefore, for the outer spherical bearings used in some silent machines, daily maintenance is mainly to prevent the intrusion of purification materials and dust.
2. Response to vibration and noise
The cleanliness of the outer spherical bearing has an equal response to the life of the needle roller bearing. The bearing has stopped special experiments for this, and the result is that the difference is several times or even dozens of times. The higher the cleanliness of the bearing, the longer the lifespan, and other people’s experiments indicate that there is no smooth oil with the same cleanliness for the life of the ball bearing. Because improving the cleanliness of the lubricating oil can extend the life of the bearing, so if the lubricating oil contains dirt particles below 10um, the life of the outer spherical bearing will be doubled.
3. Response to the smooth function The drop in the cleanliness of the outer spherical bearing does not only reflect the composition of the smooth oil film, but also causes the deterioration of the smooth grease and decelerates its aging, thereby reflecting the drop in the smooth function of the smooth grease.
The experimental results of the core of the outer spherical bearing experiment indicate that the cleanliness greatly reflects the degree of vibration of the bearing, especially the vibration of the high frequency spectrum is more obvious. The vibration progress value of the outer spherical bearing with high cleanliness is low, especially in the high frequency spectrum. Experiments have been carried out on the reaction of the dust in the grease of the outer spherical bearing to the noise.
