Abstract
The invention provides a center-adjustable cylindrical roller bearing. Rollers (6) are arranged in a pocket of a retainer seat (4) and connected through a retainer cover (5) to form an inseparable retainer component which is then jointly nested with an outer ring and an inner ring (7) to form the bearing, the outer ring is formed in such a way that an inside ring (3) with an outer spherical surface and a surface ring (1) with a corresponding inner spherical surface are assembled together through an assembly groove (2) formed in the surface ring. The center-adjustable cylindrical roller bearing has the advantages of avoiding abnormal abrasion between the rollers and a raceway caused by nonuniform loads and having a prolonged service life.
Description
Technical field
The invention belongs to field of bearings, particularly about a kind of adjusting center roller bearing, be mainly used in steel industry, be used in the floating end of hot strip rolling mill roll, also can be used for the supporting of major axis or the larger application of error of centralization.
Background technique
At present, traditional roller bearing limit due to this body structure, allow the angular error between inner ring and outer ring (i.e. error of centralization-angular error) between axle and bearing support to be only a few arc after mounting to divide, therefore, in major axis and the larger application of error of centralization, because load is uneven and cause roller and raceway to wear and tear to aggravate, substantially reduce the operating life of bearing.
Summary of the invention
In order to overcome due to the uneven and problem such as cause bearing early fatigue, life-span short of load, the invention provides a kind of adjusting center roller bearing.
Technical solution of the present invention is:
Adjusting center roller bearing, be placed on by roller and keep being connected to form inseparable retainer assembly by retainer lid in stand pocket hole, be one group of bearing with outer ring, inner ring trap again, described outer ring to be assembled together by the fitting recess be arranged on watch rim by the inner lane with outer spherical surface and the watch rim with corresponding inner ball surface formed.
When error of centralization is larger, self-aligning is realized by sphere between inner lane and watch rim, roller working surface is made to apply direction perpendicular to radial load all the time, thus make roller bus uniform force, avoid because load is uneven and cause the inordinate wear of roller and raceway, extend the life-span of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, watch rim, 2, fitting recess, 3, inner lane, 4, keep stand, 5, retainer lid, 6, cylindrical roller, 7, inner ring.
Embodiment
Now further illustrate the present invention by reference to the accompanying drawings.
In FIG, keep stand 4, retainer lid 5, cylindrical roller 6, the processing technology of inner ring 7 and assembly method identical with existing roller bearing; The inside forming the inner lane 3 of outer ring also identical with existing roller bearing, be processed into outer spherical surface outside it, inner ball surface is processed in the inside of its corresponding watch rim 1, and a side end face of watch rim 1 is processed with the fitting recess 2 of corresponding a pair symmetry.Self-aligning can be realized by sphere between inner lane 1 and watch rim 2 during use.Thus reach the object of design.
Claims (1)
1. adjusting center roller bearing, be placed on by roller (6) and keep being connected to form inseparable retainer assembly by retainer lid (5) in stand (4) pocket hole, be one group of bearing with outer ring, inner ring (7) trap again, it is characterized in that, described outer ring to be assembled together by the fitting recess (2) be arranged on watch rim by the inner lane with outer spherical surface (3) and the watch rim (1) with corresponding inner ball surface formed.
