Abstract
The invention relates to an improved full-complement cylindrical roller bearing which is characterized by comprising an outer ring, a retainer, a cylindrical roller, outer retaining rings and a middle retaining ring, wherein the middle part of the outer ring is provided with the middle retaining ring; the two outer sides of the outer ring are respectively provided with the outer retaining rings; the position on the outer ring, which has equal distance to the middle retaining ring and the outer retaining ring, is provided with an oil inlet hole; both sides of the oil inlet hole are respectively provided with an O-shaped seal ring; the inner side of the outer ring is provided with the retainer; the cylindrical roller is fixed on the lower side of the outer ring through the retainer; and a shaft sleeve is arranged below the cylindrical roller.
Description
Technical field
The field of bearings that the present invention relates to use in the machinery relates to a kind of improved four-line column roller bearing concretely.
Background technique
Along with industrial expansion, bearing is increasing in the effect of all trades and professions, and the kind of corresponding bearing is also in continuous increase, and four-line column roller bearing is exactly a series of bearing.Four-line column roller bearing generally adopts the structure with inner ring at present, can't satisfy the installation requirement of sheet material cold rolling mill.Bearing lubricating oil supply system oil leak in the course of the work, there are dirty oil and impurity fines to enter bearing inside easily again, destroy bearing element surface proper functioning, thereby reduce bearing working life.Traditional bearing generally adopts the retainer of one group of V shape two row, the quantity of restriction cylindrical roller, and the dynamic load rating and the nominal axes that define bearing are simultaneously loaded, and influence the overall performance of bearing.
Summary of the invention
Defective in view of existing procucts exist the purpose of this invention is to provide a kind of improved full-complement cylinder roller bearing.
For achieving the above object, a kind of improved full-complement cylinder roller bearing of the technology used in the present invention solution is characterized in that: be made of outer ring, retainer, cylindrical roller, outer back-up ring, guide ring; The middle part, outer ring is provided with guide ring, two outsides, outer ring are respectively equipped with outer back-up ring, the outer ring be provided with oil inlet hole with guide ring and outer back-up ring apart from the place of equating, the both sides of oil inlet hole are provided with " O " RunddichtringO, the inboard, outer ring is provided with retainer, cylindrical roller is fixed on the outer ring downside by retainer, and the cylindrical roller below is provided with axle sleeve.
Described retainer is independently window formula textural association retainers of one group of every row, and the retainer packing ring is arranged on it, and the retainer packing ring outside is provided with pillar, and retainer is separated four-row cylindrical roller.Whenever equip and carry 36 of cylindrical rollers, four row load 144 of cylindrical rollers altogether, and the dynamic load rating of bearing improves 8.5%-10%, and the nominal axes load improves 10%-15%.
The plain line of the outer round surface of described cylindrical roller is special bus finishing type.
The present invention compared with prior art has following outstanding advantage and good effect:
1, the present invention has cancelled inner ring, sets up axle sleeve on roll pins having, plays the effect of inner ring, has promptly satisfied the special requirement of mill milling technology, simplifies the structure of bearing simultaneously again, and is easy for installation.
2, the present invention sets up " O " RunddichtringO in the oil inlet hole both sides, prevents the lubricating oil supply system oil leakage, stops dirty oil and impurity fines to enter bearing internal sabotage bearing element surface proper functioning simultaneously, has improved bearing working life.
3, the present invention adopts independently window formula composite structure retainer of one group of every row, strengthened the retainer rigidity, every row set of rollers rotation is interference-free, good bearing running state, bearing life is significantly improved, increase the quantity of every line column roller simultaneously, improve the dynamic load rating and the nominal axes load of bearing, improve the overall performance of bearing.
4, the plain line of roller outer round surface is special bus finishing type, can effectively reduce or prevent the harm that edge stress is concentrated, and improves the working life of solid bearing.
Description of drawings
Fig. 1 is a structural representation of the present invention
