Abstract
The utility model relates to a conical non-standard bearing, which belongs to a bearing of a rolling machine and is composed of an outer ring, an inner ring, a roller and a roller holder. The utility model is characterized in that the big end of the rolling way of the outer ring has a right angle; no oil channel is arranged on the inner ring; the small block and the big block of the inner ring are the guiding faces of the roller holder; the end surface of the small block is higher 0.3 mm to 0.35 mm than the outer ring; therefore, when the utility model is installed, though the conical non-standard bearing is tightened, the axial play can be ensured to exist; besides, and the strength is added; therefore, the service life of the bearing is prolonged.
Description
The utility model belongs to a kind of roller-mill bearing.
Our factory is the specialized factory that produces roller-mill bearing, produces milling train and holds and four-point contact ball with four row short cylindrical roller shaft.Because a cover four spot contact bearings must be installed on the end face of four-line column roller bearing, and to bear axial force, therefore on milling train, these two kinds of bearings are installed and used simultaneously.Because four-line column roller bearing inner ring, outer ring width dimensions can not be consistent, the four-line column roller bearing inner ring is again to exchange part simultaneously, when one tightens, just destroyed the axial internal clearance (even not having play) of four spot contact bearings, revolution is got up like this, steel ball easy burn-out, lasso decortication cause this bearing to be scrapped.A general cover four row loop pillar roller bearings need 2~3 covers, four spot contact bearings to accompany.Like this, not only wasted a large amount of four spot contact bearings, and influenced the operating rate that steel are produced, caused very big economic loss to country owing to change bearing.To this problem, want to improve at four spot contact bearings itself, solving play is impossible with topic.
The purpose of this utility model is to provide a kind of milling train that replaces four spot contact bearings circular cone established line bearing.
The circular cone established line bearing is made up of inner ring, roller, roller cage and outer ring.Because the utility model has adopted roller cage, outer ring thickening, inner ring not to have oil duct, thereby increased intensity.Little retaining of inner ring and big retaining are the retainer guide surface in addition, turn over very steady like this, especially large-flange thickening, little rib end face exceeds outer ring 0.3~0.35mm, when this bearing is installed, inner ring has pushed up on the four row cylinder inner ring end faces, therefore tightens the existence that also can guarantee axial internal clearance again, thereby has improved the working life of bearing.
Because conical bearing itself bears load just greater than four spot contact bearings, therefore, can push up 2~3 covers, four spot contact bearings and use through calculating a cover circular cone established line bearing.Annual at present 200,000 covers, four spot contact bearings that only need less of China, if adopt the utility model circular cone established line bearing, only need more than 70,000 covers just passable, promote the use of the not only annual bearing usage charges that can be nearly hundred million yuan of country's savings of the utility model, and can improve steel production operational availability (reducing) because of changing the roller-mill bearing number of times.
Fig. 1 is the utility model structural representation, and the utility model is described in further detail below in conjunction with accompanying drawing.
The circular cone established line bearing is made up of outer ring 1, inner ring 2, roller 3 and retainer device.The retainer device is made up of roller cage 4 and roller cage lid 5.Be characterized in: the big end of the raceway of outer ring 1 is the right angle; Inner ring 2 no oil ducts, the little retaining of inner ring 2 and big retaining are the guide surface of roller cage 4, little rib end face exceeds outer ring 1 0.3~0.35mm; The retainer device is made of roller cage 4 and roller cage lid 5.Roller cage covers 5 rivet clasps on roller cage 4, and is into a single integrated structure.Roller cage 4 is provided with stiffening rib.
Claims (2)
1, circular cone established line bearing is made up of outer ring 1, interior cover 2, roller 3 and retainer device, it is characterized in that the big end of raceway of described outer ring 1 is the right angle; Inner ring 2 no oil ducts, the little retaining of inner ring 2 and big retaining are the guide surface of retainer 4; The retainer device is made up of roller cage 4 and roller cage lid 5, and roller cage covers 5 rivet clasps on roller cage 4, and is into a single integrated structure.
