The double-row cylinder roller bearing has the advantages of compact structure, great bearing capacity, long service life, good centering performance, etc.
Description
Technical field
The invention belongs to technical field of bearings, relate generally to the structural type of the Biserial cylindrical roller bearing of band self-aligning ring.
Background technique
What generally use on China steel mill continuous casting and continuous rolling mill at present, is Biserial cylindrical roller bearing.This bearing has bearing capacity height, rotating speed height, high temperature resistant, characteristics such as running is steady, but is subjected to the influence of structural design, and bearing only allows certain axial displacement, and does not allow error of centralization.Any angular error all can cause the bearing moment of resistance to produce, and bearing can shorten its working life because of the generation of moment.
Summary of the invention
The purpose of this invention is to provide a kind of Biserial cylindrical roller bearing, advantage such as this bearing has compact structure, bearing capacity height, long service life, aligning performance is good, rotating speed is high, operating temperature is high, running is steady with self-aligning ring.And prolonged equipment maintenance period, alleviated labor intensity, reduced the maintenance cost of main frame.
Purpose of the present invention can adopt following technological scheme to realize: its part comprises self-aligning ring, outer ring, roller, inner ring, retainer and retainer lid, it is characterized in that: self-aligning ring is an annulus that disconnects, the external diameter center has oil groove, is evenly equipped with oilhole on the oil groove, and internal diameter is concave spherical surface S φ; The outer surface of outer ring is that the outer surface center of outer ring is provided with oil groove, is evenly equipped with oilhole on the oil groove with the measure-alike protruding Spherical Surface S φ 1 of the concave spherical surface S φ of self-aligning ring; Roller is that two rows install side by side.
Respectively there is a cylndrical surface at the two ends of self-aligning ring internal diameter, and oilhole and annulus gap on the oil groove of external diameter center are certain included angle; Retainer pocket hole is that arc pocket hole is that circular arc contacts with the rolling surface of roller.
By last structure as can be seen, roller of the present invention is that two rows install side by side, cancelled centre rib, roller length has extended, promptly improved load bearing capacity, load has been distributed uniformly, when bearing generation unbalance loading, can not pull, make bearing stuck phenomenon occur because of roller is long.Retainer is a rolling element guiding form, employing carries the structure of rivet, roller is packed into and is riveted with the retainer lid behind the pocket hole, this structure retainer can make the deck-siding between the two pocket holes narrow down, can suitably increase roller diameter or quantity, thereby improved the load capacity of bearing, retainer pocket hole is that arc pocket hole is that circular arc contacts with the rolling surface of roller, makes the running of bearing more steady.Self-aligning ring is an annulus that disconnects, with packing into of convenient outer assembly, the external diameter center has oil groove, be evenly equipped with oilhole on the oil groove, and be certain included angle (during Bearing Installation with the annulus gap, oilhole is aimed at oil hole, the gap of annulus will be avoided loading zone), be beneficial to lubricant grease and successfully enter, to the fitting surface lubricate of self-aligning ring and outer ring, with the temperature rise that prevents to cause by sliding friction, internal diameter is concave spherical surface S φ, cooperate the aligning effect with the protruding Spherical Surface S φ 1 of outer ring, a cylndrical surface has respectively been arranged at two ends, be beneficial to the assembling of bearing.The outer surface of outer ring is with the measure-alike protruding Spherical Surface S φ 1 of the concave spherical surface S φ of self-aligning ring, cooperated the aligning effect with self-aligning ring, the center of outer spherical surface has oil groove, is evenly equipped with oilhole on the oil groove, be beneficial to lubricant grease and successfully enter bearing inside, the greasy property of bearing is improved.Advantages such as in sum, the present invention has compact structure, bearing capacity height, long service life, aligning performance is good, rotating speed is high, operating temperature is high, running is steady.And prolonged equipment maintenance period, alleviated labor intensity, reduced the maintenance cost of main frame.
