Abstract
The utility model discloses a spherical surface outer ring double-row cylindrical roller bearing, which comprises an outer ring (1), an inner ring (2), a holder (3) and two rows of cylindrical rollers (5), wherein the external diameter of the outer ring is a spherical surface, the two rows of the cylindrical rollers are arranged in parallel, one end of the inner ring is provided with a fixed retaining edge (7) used for limiting one sides of the cylindrical rollers and bearing the radial loading of the cylindrical rollers in one direction, the other end of the inner ring is provided with a movable damper edge (8) used for limiting the other sides of the cylindrical rollers and bearing the radial loading in the other direction. The bearing has the characteristics that the phenomenon of one-sided loading does not exist, the bearing is the combination of a sliding bearing and a rolling bearing, the structure is simple, the manufacturing is easy, and the service life is long.
Description
Technical field
The present invention relates to a kind of bearing, more specifically to a kind of Biserial cylindrical roller bearing.
Background technique
The used by oscillating screen bearing of prior art is provided with selfaligning roller bearing outside its roller bearing, problem is that bearing is relatively heavier, has the unbalance loading phenomenon.And the selfaligning roller bearing that this type of machine uses, its inside and outside circle raceway promptly bears radial load and bears axial load again.When surpassing usage requirement, cause row roller overload, row roller unloading, although not serious, also can cause unbalance loading, quickened a row bearing and be damaged because of fatigue.
Summary of the invention
At the problems referred to above, the invention provides a kind of special-purpose Biserial cylindrical roller bearing, its purpose aims to provide a kind of radial load that bears, the bearing of long service life.
The present invention proposes a kind of Biserial cylindrical roller bearing, comprise outer ring, inner ring, retainer and two line column rollers; The external diameter of described outer ring is a sphere; Described two line column rollers are placed side by side; One end of described inner ring has fixedly rib, is used to be defined in a side of cylindrical roller, bears cylindrical roller radial load in one direction; The other end of described inner ring is provided with the sliding damper limit, is used to be defined in the opposite side of cylindrical roller, bears the radial load of other direction.
By technique scheme, the Biserial cylindrical roller bearing of using of the present invention, there is not the unbalance loading phenomenon in its radial and axial bearing load respectively, and is the combination of sliding bearing and rolling bearing, the yet corresponding increase of the ability to bear of its radial load.Therefore bearing of the present invention have simple in structure, be easy to process, the characteristics of long service life.
Description of drawings
Fig. 1 be Biserial cylindrical roller bearing of the present invention partly cut open structural representation, omit the bottom symplex structure.
Embodiment
As shown in Figure 1, bearing of the present invention is made up of outer ring 1, inner ring 2, maintenance stand 3, retainer lid 4, roller 5 and rivet (not marking).The radial surface of outer ring is a sphere, and retainer lid 4 is connected the formation retainer with keeping stand 3 by rivet.Retainer places between outer ring 1 and the inner ring 2.Roller 5 is packed into and is kept in the pocket hole of stand 3.One end of inner ring 2 is fixing rib 7, is positioned at a side of a row roller, is used to bear cylindrical roller radial load in one direction; The other end of inner ring 2 is provided with sliding damper limit 8, is defined in the opposite side of another line column roller, is used to bear the radial load of other direction.Fixedly the length of rib 7 one side cylindrical rollers is long than the cylindrical roller of opposite side.
Claims (2)
1, a kind of spherical outer ring Biserial cylindrical roller bearing is characterized in that: comprise outer ring (1), inner ring (2), retainer (3) and two line column rollers (5); Wherein:
The radial surface of described outer ring is a sphere;
Described two line column rollers are placed side by side, and the parallel axes of each cylindrical roller or coincidence are provided with;
One end of described inner ring has fixedly rib (7); The other end of described inner ring is provided with sliding damper limit (8).
2, according to the Biserial cylindrical roller bearing of the described spherical outer ring of claim 1, it is characterized in that: the length of described fixedly rib (7) one side cylindrical rollers is long than the cylindrical roller of opposite side.
