Abstract
The invention discloses a kind of double-row roller bearing without flange that is mainly used in metallurgy, milling equipment, comprise outer ring (01), cylindrical roller (04), retainer and inner ring (02); The external cylindrical surface of inner ring (02) is provided with annular boss, the boss both ends of the surface end face of both sides cylindrical roller (04) that reclines respectively, thus limit the axial position of two row rollers.Each retainer comprises the maintenance stand (06) and the retainer lid (16) of ring-type; Keep stand (06) to become pectination, form uniform pocket hole on the circumference between broach, the nose of comb opening is used to load and unload cylindrical roller; Pack into behind the cylindrical roller, retainer lid (16) is buckled in the opening end that keeps stand (06), thereby cylindrical roller is contained in the pocket hole.That double-row roller bearing without flange of the present invention has is simple in structure, be easy to make, rigidity by force, the characteristics of not yielding, long service life.
Description
Technical field
The present invention relates to a kind of bearing, more particularly, relate to a kind of Biserial cylindrical roller bearing.
Background technique
The Biserial cylindrical roller bearing that present domestic metallurgy industry uses is made up of an inner ring, outer ring, riveting and retainer and a row long cylinder roller.Problem is that the roller length of this class bearing is longer, and the contact of roller and raceway is relatively poor, and with respect to cylindrical roller bearing, ability to work coefficient and limit revolution are all lower.And the retainer that bearing adopts is to be formed by two ribs and several pillar riveteds, because pillar is longer, retainer can occur twisting the strength phenomenon during riveted, and skew easily takes place roller when rotated.Be the guide rolls rotation, the roller two ends all have hinge, and manufacturability is relatively poor, and the roller hinge easily ruptures during rotation.And the bearing power that in use is hit is bigger, and therefore riveted pillar limited amount grows existing riveted point to strut, the phenomenon that causes retainer to destroy.Above various factors has all reduced the working life of bearing.
Summary of the invention
At the problems referred to above, the invention provides a kind of double-row roller bearing without flange that is mainly used in long service life on metallurgy, the milling equipment.
In order to achieve the above object, the present invention has constructed a kind of double-row roller bearing without flange, comprises outer ring, cylindrical roller and inner ring.Cylindrical roller becomes two row; The neutral position of inner ring external cylindrical surface is provided with annular boss, the boss both ends of the surface end face of both sides cylindrical roller that reclines respectively, thus limit the axial position of two row rollers.This bearing also comprises the retainer between outer ring and inner ring; Retainer comprises the maintenance stand and the retainer lid of ring-type.Keep stand to become pectination, form uniform pocket hole on the circumference between broach, the nose of comb opening is used to load and unload cylindrical roller; Pack into behind the cylindrical roller, the retainer lid is buckled in the opening end that keeps stand, thereby cylindrical roller is held in the pocket hole.
By technique scheme, double-row roller bearing without flange of the present invention is mainly used in metallurgy, milling equipment, have simple in structure, be easy to make, rigidity by force, the characteristics of not yielding, long service life.
Description of drawings
Fig. 1 be double-row roller bearing without flange partly cut open structural representation, omit lower half portion of symmetry among the figure.
Embodiment
As shown in Figure 1, double-row roller bearing without flange of the present invention comprises a passive outer ring 01, two row short columnar rollers 04 and one and the friction tight inner ring 02 of milling train axle.The neutral position of inner ring 02 external cylindrical surface is provided with annular boss, the boss both ends of the surface end face of both sides cylindrical roller 04 that reclines respectively, thus limit the axial position of two row rollers.
This bearing also comprises the retainer between outer ring 01 and inner ring 02, and retainer 06 rotates with main shaft, comprises two ring-type solid cages, limits two line column rollers respectively.Each retainer comprises the maintenance stand 06 and the retainer lid 16 of ring-type.Keep 06 one-tenth pectination of stand, form uniform pocket hole on the circumference between broach, the nose of comb opening is used to load and unload cylindrical roller; Pack into behind the cylindrical roller, retainer lid 16 is buckled in the opening end that keeps stand 06, and cold riveting fixes, thereby cylindrical roller 04 is housed inside in the pocket hole of retainer.
Claims (1)
