摘要： A gap between a bearing box and a roll portion and so on which are not used for absorbing an expansion of a roll are reduced, and by increasing axial widths of the bearing box and cylindrical roller bearing for that, a loading capacity of the cylindrical roller bearing is enhanced.
A first side face 13A of the bearing box 13 located at one side in the axial direction is disposed outwardly with respect to a central line Y2 between two roll portions 22A, 22B than a second side face 13B located at an other side in the axial direction, and a gap al between this first side face 13A and the roll portion 22A opposed thereto is made smaller than a gap a2 between the second side face 13B and the roll portion 22B opposed thereto.

摘要： Thrust tapered roller bearings are arranged at axially opposite ends of a cylindrical roller bearing having an aligning ring, an inner ring, an outer ring, and cylindrical rollers. Each of the thrust tapered roller bearings has tapered rollers arranged between a first raceway surface provided on each of axial outer surfaces of the outer ring and a second raceway surface of each of side raceway rings placed on the axially outward sides of the outer ring. Further, the point of intersection between extension lines from those generating lines of the tapered rollers which are in contact with the first and second raceway surfaces and the point of intersection between extension lines from the first and second raceway surfaces are positioned at the center of curvature of an aligning slide surface of the aligning ring.

摘要： A tapered roller thrust bearing is disposed in each of both sides in an axial direction of a cylindrical roller bearing with aligning housing ring which is provided with an inner ring, an outer ring, cylindrical rollers and an aligning housing ring. The tapered roller thrust bearing is constituted by disposing tapered rollers between a first raceway surface which is an outer side face in the axial direction of the outer ring and a second raceway surface of a side raceway ring disposed in an outer side in the axial direction of the outer ring. An intersection of lines extended from generatrices of each of the tapered rollers which are in contact with the first raceway surface and the second raceway surface, and an intersection of lines extended from the first raceway surface and the second raceway surface are disposed on a curvature center O of the aligning sliding surface.

摘要： An inner ring is formed with an oil hole extending through a part between an inner ring raceway surface and an inner peripheral face thereof, and configured to force out grease, which has been supplied to an area between the inner ring raceway surface and an outer ring raceway surface, to the inner peripheral face in accordance with rolling of cylindrical rollers. The inner peripheral face of the inner ring is formed with a plurality of V-shaped inclined grooves configured to guide the grease, which has been forced out to the inner peripheral face of the inner ring through the oil hole, to opposite end portions of the inner peripheral face in an axial direction of the inner ring.
摘要翻译：在内圈形成有贯通内圈滚道面与内圈面之间的部分的油孔，该油孔被供给到内圈滚道面与外圈之间的区域滚道表面与圆柱滚子的滚动相对应的内周面。内圈的内周面形成有多个V形的倾斜槽，该多个V形的倾斜槽构造成将已经通过油孔被挤出至内圈的内周面的润滑脂引导至该内圈的相对端部内圈的轴向内周面。
