    摘要: A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.

    摘要: An anti-rotation assembly for use in preventing rotation of an outer race of a radial bearing with regard to a housing in which the radial bearing is mounted, the assembly including a housing with a cylindrical bore defined by a side wall, a recess extending radially-outwardly from the side wall of the cylindrical bore, and a snap ring including a pair of protrusions extending radially-outwardly therefrom, wherein the pair of projections are selectively received within the recess, thereby preventing rotation of the snap ring with respect to the housing.

    摘要: A roller bearing includes an outer ring, an inner ring, and plural rolling elements rollably interposed between mutual raceway surfaces of the outer and inner rings, and is used by fitting an outer diameter surface of the outer ring serving as a fitting surface to a housing serving as a mating member or by fitting an inner diameter surface of the inner ring serving as a fitting surface to a shaft serving as the mating member. The fitting surface is provided with at least one protrusion so that a static torque Thold=Σ(F×r) generated by the protrusion is equal to or greater than a torque Tcreep generated by creep.

    摘要: Disclosed is a sealed bearing arrangement that provides at least a bearing with an outer ring and an inner ring, which are rotatable to each other and form a rolling chamber between each other, in which a set of rolling elements. A lubricant is encompassed in the rolling chamber and the rolling chamber is sealed off from an environment by at least one sealing element. The inner ring, the outer ring and/or the sealing element includes at least one opening for providing a fluid passage through the sealing element. The bearing is arranged in a housing that is adapted to seal off the bearing from an outside environment. A lubricant is encompassed inside the housing. The housing including the at least one opening for providing a fluid passage from the inside of the housing to the outside. The opening is fluid tightly connected to an oxygen removing element and/or to a gas tank, which provides an oxygen poor to free fluid flow to the rolling chamber.

    摘要: A system for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft and a press mechanism in fluid communication with a source of fluid and configured to provide a compressive load to the bearing. The press mechanism includes a switch having a base and a piston in communication with the fluid such that an increase in a pressure of the fluid results in the piston extending upwardly from the base and a decrease in the pressure of the fluid results in the piston retracting toward the base. The switch includes a lower proximity sensor and a higher proximity sensor. The piston is configured to extend upwardly from the base past the lower proximity sensor and to trip the higher proximity sensor. The switch is configured to control the increase in the pressure in response to the piston tripping the higher proximity sensor.
