摘要： A tapered roller bearing 1 comprises an inner ring 2, an outer ring 3, a plurality of tapered rollers 4 rollably disposed between the inner and outer rings, and a cage 5 for holding the tapered rollers at predetermined circumferential intervals. In this tapered roller bearing, the roller coefficient {y=(the number of rollers ×mean roller diameter)/(π×PCD)} is greater than 0.94. At least one of the members, i.e., the outer ring, inner ring, and rolling elements, has a nitrogen rich layer. The grain size number of austenite crystal grains in the nitrogen rich layer exceeds number 10.

摘要： A tapered roller bearing comprises inner and outer and outer rings having raceways, a large flange surface and a small flange surface, tapered rollers between the raceways and each having large and small end faces at the ends, and a retainer for the tapered rollers. The average roughness of the large end faces and the large flange surface is 0.14 &mgr;m Ra or less. The radius of curvature of the large end faces is 75 to 85% of the roller reference radius, and the central angle of the contact positions between the tapered rollers and the large flange surface is {fraction (1/15)} to {fraction (1/10)} of the roller angle. The center of the contact surface between the tapered rollers and the raceways is offset toward the large end faces from the center of the rolling surfaces of the tapered rollers by 10% or less of the effective length of the tapered rollers.

摘要： A star-branched polyester polyol is obtained by polymerizing lactide or lactic acid, using, as an initiator, a fat and oil composed mainly of a triacylglycerol that has at least three hydroxyl groups or epoxy groups in its molecule. This polyester polyol has low crystallinity and a low melting point, and thus shows good working properties when used in various applications. Furthermore, this polyester polyol is derived from renewable resources, and, thus, it is highly desirable in view of its effectiveness in protecting the global environment and preventing fossil resources from being depleted.
