High-speed bearing, particularly of the spinning machine

摘要

High speed bearing, especially for textile machinery consisting of a shaft (3) with two inner raceways (1) and (2) with diameters of (Di1), (Di2) and widths of (B1 ), (B2) created directly into the shaft with a distance of (1), an outer ring (4) with two outer raceways created directly into the outer ring, balls (5) led by cages (6) in bearing raceways, shields (7) and of grease wherein a strengthened part of the shaft is extended to space of both raceways (1) and (2) and its length is shorter than the length (LH) of the outer ring (4) and simultaneously an optional diameter (D), (D1), (D2) of the strengthened shaft part (3) is bigger than an optional diameter of raceways (1) and (2) and simultaneously an optional diameter (d1), (d2) of shaft ends is smaller than an optional diameter (D), (D1),(D2) of strengthened part (3).
