Title:
ROLLER BEARING AND METHOD FOR USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2014/010542
Kind Code:
A1
Abstract:
Provided is a roller bearing equipped with a structure for preventing direct contact between rolling elements that are subjected to a load, or a structure for preventing indirect competition, through a partition wall intervening between rolling elements, between rolling elements that are subjected to a load, wherein a difference in the amount of thermal expansion between the inner and outer races due to a temperature differential is utilized to bring the bearing into a pre-compressed state during operation when the inner race reaches higher temperature than the outer race, and prevent premature damage due to skew of the rolling elements and the like. When at a stop, on the other hand, the bearing is brought into a non-precompressed state by virtue of the inner race and the outer race being at approximately the same temperature, facilitating assembly/disassembly operations thereof.
