Heating is a common problem in the operation of bearings, and there are many factors that can cause high temperatures in outer spherical bearings. Relatively speaking, there are five common types of temperature rise. After understanding different factors that cause temperature rise in outer spherical bearings, it is necessary to take appropriate measures to completely eliminate the danger of high temperatures in outer spherical bearings. Relative solutions are also inevitable.

1. Response to the Bearing Life of Outer Spherical Bearings

Due to the absolute invasion of active and purified dust, the wear and tear of the bone body and raceway occur. When the amount of wear is large, it is the increase in bearings, noise, and vibration that increases the operating precision of the bearings, thus indirectly reflecting the precision of some long machines

Density. Therefore, for some quiet machines using outer spherical bearings, daily maintenance is mainly to prevent the invasion of purified dust.

2. Response to vibration noise

The cleanliness of outer spherical bearings has a significant impact on the lifespan of needle roller bearings. The bearings have stopped special experiments for this, resulting in differences of several times or even tens of times. The higher the cleanliness of the bearings, the longer their lifespan, and other experiments have shown that there are no bearings with the same cleanliness

Smooth oil has a significant effect on the lifespan of ball bearings. Because improving the cleanliness of the smooth oil can extend the lifespan of the bearing, if the smooth oil contains dirt particles below 10um, the lifespan of the outer spherical bearing will also be doubled.

3. The decrease in cleanliness of outer spherical bearings does not only reflect the composition of the smooth oil film, but also triggers the transformation and aging of the smooth grease, thereby reflecting the decrease in smooth function of the smooth grease.

The experimental results of the core of the outer spherical bearing experiment indicate that cleanliness significantly reflects the degree of vibration of the bearing, especially the high-frequency vibration. The vibration progress value of the outer spherical bearing with high cleanliness is low, especially in the high-frequency spectrum, for the outer spherical bearing grease

Experiments have been conducted on the response of dust to noise, confirming that the more dust, the greater the noise.
