Abstract
PURPOSE: To releave a main shaft of load, to elongate the use life of the main shaft, and to prevent skidding by providing auxiliary roller bearings close to a main bearing and applying auxiliary radial load.
CONSTITUTION: Auxiliary roller ball bearings 71b and 72b are arranged on both sides of main bearing cylindrical roller ball bearings 41b and 42b applied with a main radial load. The bearings 71b and 72b are provided with a loading device 8b for applying an auxiliary radial load p, and the outer wheels of the bearings 71b and 72b are so mounted as to be radially movable relative to a housing 6b. The load p is transmitted through a shaft 51b to the bearings 41b and 42b, to prevnt the skidding. With the direction of the load p so set that the angle formed between the direction of the main radial load Pr and the direction of the load p is (90+ θ)° and that θ satisfies formula I, the resultant load P is made smaller than the load Pr and the use life of the main bearings 41b and 42b is elongated.
