    摘要: A gear having an axis of rotation includes a gear rim, with at least a portion of the gear rim configured to receive a load and define a loaded gear rim arc corresponding to the portion of the gear rim. A bearing pin extends axially through the gear rim, the gear rim and the bearing pin defining a roller element gap therebetween. The gear rim is configured to define a loaded roller element gap arc substantially concentric with the loaded gear rim arc, the loaded element gap arc having a loaded roller element gap arc length. The gear rim is further configured to retain a loaded bearing portion of the bearing within the portion of the roller element gap such that a loaded bearing portion length is in a range from and including about 75% to and including about 125% of the loaded roller element gap arc length.

    摘要: A self-aligning roller bearing having inner and outer bearing ring elements and at least one row of roller elements disposed in between. The inner bearing ring element having a retaining flange provided on a first axial side of the roller bearing being configured for preventing the roller elements from falling out from the roller bearing. The roller bearing having a first sealing ring element located at the first axial side for sealing the first axial opening, the first sealing ring being rotatable in relation to the inner bearing ring and seals against a sealing mating surface of the inner bearing ring. The retaining flange has at least one filling slot configured for allowing the roller elements to be inserted in-between the inner and the outer bearing ring elements during assembly of the roller bearing, and the sealing mating surface being axially outside the at least one filling slot.

    摘要: A roller structure including a cylindrical casing having an outer wear surface and an inner surface provided by a bore extending through the cylindrical casing. At least one anti-friction bearing is positioned within the bore in contact with the inside surface of the cylindrical casing. The anti-friction bearing includes a solid lubricant. In one embodiment, the roller structure is a roller turn roller and is a component of a guide for a turn of a conveyor system, wherein the outer wear surface is for contacting the chain of the conveyer system. A method of lubricating a roller structure is also provided.

    摘要: A machine assembly includes a housing in which a shaft element is rotatably supported by a bearing assembly, the bearing assembly including two tapered roller bearings which are preloadable against each other and having at least one bearing outer ring and first and second bearing inner rings. The first bearing inner ring includes, in one of its axial end regions, a sleeve-shaped extension formed directly from the material of the first bearing inner ring, which sleeve-shaped extension directly contacts an end side of the second bearing inner ring.
