Multirow ball roller bearing has two or more rows of ball rollers on common rotational axis with proportional diameters and widths so that the cone tips of envelope curves are arranged where axis intersects with lengthwise axis of bearing

摘要

Multirow roller bearing (1) consists of outer (2) and inner (3) bearing rings, and many evenly spaced ball rollers (5,6) arranged between rings in at least two rows (7,8). Neighboring ball rollers in each row are arranged on a common rotational axis at right angles to pressure angle axes. In this way they have proportional diameters and widths so that the cone tips of all the rollers, on their envelope curves tangential to these diameters, are arranged exactly on the intersection of the common rotational axis with the lengthwise axis of the bearing.
