Abstract
The utility model discloses a non-baffle double-row roller bearing which is mainly applied in the metallurgy and a rolling mill equipment, which comprises an outer ring (01), a roller (04), a retainer and an inner ring (02). A ring shaped boss is arranged on the external cylinder face of the inner ring (02). Two end faces of the boss are respectively attached to the end face of the roller (04) on two sides, thereby limiting the axial position of two rows of the roller. Each retainer comprises a ring shaped maintenance seat (06) and a retainer cap (16). The retainer seat represents a comb shaped and a pocket hole is formed on the circumference among the comb teeth evenly. The opening of the comb tooth end is applied to load and unload the roller. The retainer cap (16) is chucked on the opening end of the retainer seat (06) after the roller is loaded, thereby containing the roller in the pocket hole. The non-baffle double-row roller bearing of the utility model has the advantages of simple structure, easy manufacturing, strong rigidity, uneasy deformation and long use life.
Description
Technical field
The utility model relates to a kind of bearing, more particularly, relates 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, foreign country, 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 utility model 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 utility model has been constructed a kind of double-row roller bearing without flange, comprises foreign country, cylindrical roller and inner ring.Cylindrical roller becomes two row; The neutral position of interior state 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 foreign country 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 utility model 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 utility model comprises a passive foreign country 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 foreign country 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)
