Abstract
The invention discloses a cylinder roller bearing, comprising an integral inner ring (02), an outer ring (01) and two columns of cylinder rollers; each column of the cylinder rollers are limited by a retainer, and the retainer comprises a pair of retainer bases (06) which are axially buckled along the bearing and a retaining lid (16); the retainer bases (06) and the retaining lid are fixed by a rivet (09) which penetrates in axially; ring-shaped side retaining rings (11) are arranged on the two end surfaces of the outer ring (01), the bore diameter of the side retaining rings (11) is less than that of a shaft hole of the outer ring (01), so as to lead the side retaining rings (11) to push against to the outer side end surfaces of each column of the cylinder rollers; a ring-shaped central retaining ring (03) is arranged between the two columns of the cylinder rollers, and the central retaining ring (03) is sheathed on the inner ring (02); in the invention, the rotating flexibility of the bearing is improved, the service life of the bearing is improved, automation can be easily realized, the precision is improved and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of bearing.
Background technique
Present existing Biserial cylindrical roller bearing majority is outer ring, inner ring, roller, retainer formation, general outer ring all is band centre rib and side bumper limit, like this in course of working, operation is very complicated, and is cumbersome, and when producing in a large number, manufacturing efficiency is low, be difficult to realize full-automation, and when the grinding rib, be easy to crack, brought enormous economic loss to us.
Summary of the invention
The objective of the invention is provides a kind of long service life in order to address the aforementioned drawbacks, the roller bearing that rotate flexibly, torque force is big.
The present invention adopts following technical proposals to realize:
A kind of roller bearing comprises integrated type inner ring, integral type outer race, and two line column rollers between inner ring and the outer ring.Each line column roller is limited by a retainer, and retainer comprises along bearing shaft adds a cover to a pair of maintenance stand, the maintenance of snapping.The rivet cross-under that keeps stand and keep adding a cover by being provided with is vertically fixed.Two end faces are provided with the annular edge back-up ring in the outer ring, and the aperture of side bumper circle is less than the axis hole aperture of outer ring, thereby the side bumper circle is resisted against the outside end face of every line column roller, is used to limit the axial position of cylindrical roller.Be provided with ring washer in the annular between two line column rollers, middle-grade snare is connected on the described inner ring.
The present invention has following advantage: owing to be two row rollers, the parallel area of contact of advancing with raceway of roller has increased, and has improved bearing and has executed the commentaries on classics flexibility, has improved bearing working life.So because designs simplification is very easy to the realization automation in course of working, improved precision, improved manufacturing efficiency.

Fig. 1 be bearing of the present invention partly cut open structural representation, omit the Lower Half structure of symmetry among the figure.
Embodiment
As shown in Figure 1, a kind of roller bearing comprises integrated type inner ring 02, integral type outer race 01, and two line column rollers between inner ring and the outer ring.Each line column roller is limited by a retainer, and retainer comprises along bearing shaft adds a cover 16 to a pair of maintenance stand 06, the maintenance of snapping.Keep stand 06, keep adding a cover 16 and fix by rivet 09 cross-under that is provided with vertically.01 two end faces are provided with annular edge back-up ring 11 in the outer ring, and the aperture of side bumper circle 11 is less than the axis hole aperture of described outer ring 01, thereby side bumper circle 11 is resisted against the outside end face of every line column roller, is used to limit the axial position of cylindrical roller; Be provided with ring washer 03 in the annular between two line column rollers, middle ring washer 03 is socketed on the inner ring 02.
Biserial cylindrical roller bearing of the present invention comprises inner ring, periphery, maintenance stand, keeps adding a cover, rivet, rolling element, side bumper circle and middle ring washer.Wherein the outer ring is a circular shape, and the centre is provided with oil groove, and is porose, the both sides, outer ring are provided with the side bumper circle, rolling element places and keeps in stand 06 and the retainer lid 16, and inner ring is a circular shape, and middle ring washer is that circular shape, middle ring washer 03 place on inner ring 02 external diameter and be used for adjusting two rolling elements.
Claims (1)
1. a roller bearing is characterized in that, comprises integrated type inner ring (02), integral type outer race (01), and two line column rollers between described inner ring and the outer ring;
Each line column roller is limited by a retainer, and described retainer comprises along bearing shaft adds a cover (16) to a pair of maintenance stand (06), the maintenance of snapping; It is fixing by the rivet that cross-under is set vertically (09) that (16) are added a cover in described maintenance stand (06), maintenance;
(01) two end face is provided with annular edge back-up ring (11) in described outer ring, the aperture of described side bumper circle (11) is less than the axis hole aperture of described outer ring (01), thereby described side bumper circle (11) is resisted against the outside end face of described every line column roller, is used to limit the axial position of cylindrical roller; Be provided with ring washer (03) in the annular between two line column rollers, described middle ring washer (03) is socketed on the described inner ring (02).
