Abstract
The utility model relates to a split self-aligning roller bearing for a steel refining furnace trunnion. The split self-aligning roller bearing comprises a bearing body which is in clearance fit with the inner diameter surface of a box body of a fixed bearing; and the outer surface of an outer ring of the bearing body is provided with a guide key which is matched with an axial groove in the inner diameter surface of the box body of the fixed bearing and can be used for limiting the relative rotation between the outer ring and the box body. The split self-aligning roller bearing for the steel refining furnace trunnion is reasonable in structural design, can limit the relative rotation between the outer ring of the bearing and the box body, and solves the problem of unbalance loading of the bearing caused by axial displacement of the trunnion which is influenced by operating temperatures, so that the service life of the bearing is greatly prolonged.

Described bearing body comprises inner ring, retainer and the outer ring that sets gradually from inside to outside; Described outer ring is comprised of two semi outer rings of docking up and down, is provided with feather key in the middle part of the outer surface of at least one semi outer rings; Described retainer comprises that the two halves of mutual docking keep stand, partly keep the both sides of stand to be respectively equipped with half retainer lid at each, be provided with several pockets holes along even circumferential respectively in the both sides that partly keep stand, be located at half and keep the pocket hole of stand both sides to be symmetrically set, be equipped with a rolling element in each pocket hole; Described inner ring is comprised of two and half inner rings docking, is respectively equipped with half clamp ring in the chucking ring recess of each half inner ring outer surface both sides, and two and half clamp rings that are located at two and half inner ring the same sides are connected by screw.
Be provided with an annular oil groove along circumference in the middle part of the outer surface of outer ring, be provided with several along even circumferential and be used for tapped hole lubricated and lifting in oil groove.
Be respectively equipped with the tapped hole that several are used for lifting in the chucking ring recess of each half every side of inner ring.
Be equipped with a tapped hole that is used for lifting in the middle part of the outer surface of each half clamp ring.
The utility model adopts such scheme, reasonable in design, with inner ring, outer ring and the retainer of bearing body vertically subdivision be two halves, make the installation of bearing body and change more convenient, shorten fault power time, reduced installation and maintenance cost, improved working efficiency; Make simultaneously two semi outer rings and casing Spielpassung, and the feather key that matches by the axial notch of setting up at the outer surface of semi outer rings middle part on the casing inside diameter surface with rigid bearing, both limited relatively rotating of bearing outer ring and casing, solve again the gauche bearings problem that the axial displacement that is subjected to operating temperature to affect generation due to gudgeon causes, greatly extended the working life of bearing.
