Effect of lubrication on speed ability

- Jul 13, 2017-

The design of tapered roller bearings will lead to the lubricant pumping effect, that is, the lubricant is flowing from the small end of the roller to the end of the pressure. As the speed increases, the lubricant begins to flow outward under the action of centrifugal force. When the speed is too large, we need to consider the roller big end and

The contact between the rim surfaces, which is the main reason for the big end, the outer ring design of the bottom of the edge, or the high speed TSMA to adopt the fuel injection lubrication when the running speed increases.

For tapered roller bearings, there is no apparent limit of the rotational speed limit because the performance depends on the bearing design and lubrication system and the bearing has a low G1 coefficient of typical industrial experience related to speed and temperature.
