摘要： A connecting rod of an internal combustion engine, that includes a large bore, and an interior bore surface. The current art uses soft metal bearing surfaces to reduce wear, and friction between the connecting rod inner diameter and the crankshaft journal surface. The soft metal bearing surface is a separate component of the engine. In this invention the large bore end interior diameter is coated with a hard material to reduce, or eliminate wear. The hard material is a metal or metal alloy applied to the inner diameter by a thermal spray method. A relatively soft polymer material can also be applied to the interior diameter surface of the con-rod bore. The relatively softer polymer acts as a first and sometimes a consumable layer, and applied over the thermal sprayed hard layer. The polymer layer is often used in conjunction with the sprayed metal layer. The polymer coating may be worn off the inner diameter surface; this delay in surface to surface contact to the sprayed metal layer has beneficial effects on the sprayed metal layer. The delay of surface to surface contact will usually result in a longer service life of the sprayed metal coating.

摘要： A spindle motor includes an upper bearing portion and a lower bearing portion each of which is inclined with respect to a central axis. The upper bearing portion includes an upper dynamic pressure generating groove defined in at least one of an upper outer circumferential surface of a shaft portion and an upper inner circumferential surface of a sleeve. The lower bearing portion includes a lower dynamic pressure generating groove defined in at least one of a lower outer circumferential surface of the shaft portion and a lower inner circumferential surface of the sleeve. The radial distance between a lower end portion of the upper dynamic pressure generating groove and the central axis is shorter than the radial distance between an upper end portion of the lower dynamic pressure generating groove and the central axis.

摘要： A steering shaft for a steering system of a motor vehicle, comprises an inner shaft mounted axially displaceably in a hollow shaft, wherein a rolling bearing having multiple metallic rolling elements, which are disposed axially in at least two rows, is disposed between the hollow shaft and the inner shaft. Previously known steering shafts cannot reliably present vibrations from being transmitted from the inner shaft to the hollow shaft. Therefore, the diameters of the metallic rolling elements decreases proceeding from the center of the rolling bearing toward the end faces thereof, wherein multiple mutually adjacent metallic rolling elements have identical and/or different diameters.

摘要： In a sealed rolling bearing for use in an environment where a large amount of water is splashed and the internal pressure of the bearing becomes negative, a ratio of the difference between an outer diameter of a seal sliding contact surface of an inner race and an inner diameter of a seal lip of an elastic seal member in its natural state to a diameter of a roll neck portion (shaft) on which the inner race is fitted is in the range of 0.27 to 0.40%. This provides reduced frictional heat generation of the seal lip and adequate pressing force applied to the seal lip, thus securing excellent seal performance without requiring an additional mechanism, such as a vent to a contact seal.
