Abstract

The invention relates to a bearing for a packing machine. The bearing comprises an outer ring, an inner ring and a retaining ring, wherein one end of the inner ring is provided with a shaft shoulder, the inner ring is arranged in the outer ring, and the retaining ring is arranged at the other end, corresponding to the shaft shoulder, of the inner ring. The bearing is characterized by also comprising dustproof covers, short rollers and long rollers, wherein the outer surfaces of the shaft shoulder and the retaining ring are respectively provided with a groove which is internally provided with one dustproof cover; the short rollers and the long rollers are arranged between the outer ring and the inner ring; the arrangement mode of the short rollers and the long rollers in each row is as follows: in one row, the two short rollers are arranged at the middle in a close manner, the two long rollers are arranged at the two sides of the two short rollers; in the adjacent row, when the two long rollers are arranged at the middle in a close manner, the two short rollers are arranged at the two sides of the two long rollers, and are arranged in a staggered manner in each row; and a pluralityof grease holes are formed on the inner wall of the inner ring. The bearing has the advantages that the hazard caused by impact load and uneven load can be effectively eliminated, uneven wear of rolling ways can be effectively eliminated, and the service lives of sealing and the bearing are prolonged.

Description

The packer bearing

Technical field

The present invention relates to a kind of bearing, relate in particular to a kind of packer bearing.

Background technique

Present packer comprises outer ring, inner ring, back-up ring and roller with bearing; Wherein the end at inner ring is provided with the shaft shoulder, and inner ring is installed in the outer ring, and back-up ring is installed in the other end of the inner ring corresponding with the shaft shoulder, and roller is installed between outer ring and the inner ring, transversely arranged two of roller; Easily produce harm thus when being subjected to impulsive load and uneven load, roller easily produces uneven wear simultaneously, makes that the working life of bearing and reliability are not high.

Summary of the invention

At above-mentioned shortcoming, the object of the present invention is to provide a kind of packer bearing; It can effectively eliminate the harm that impulsive load and uneven load are brought, and can effectively eliminate the raceway uneven wear, and the life-span of improving sealing and bearing, limits and reliability thereby can improve baering life.

Technology contents of the present invention is: the packer bearing comprises outer ring, inner ring and back-up ring; End at inner ring is provided with the shaft shoulder, and inner ring is installed in the outer ring, and back-up ring is installed in the other end of the inner ring corresponding with the shaft shoulder; It is characterized in that it also comprises dust cover, short roller and long roller; Outer surface at the shaft shoulder and back-up ring respectively is provided with a groove, is provided with a dust cover in groove; Short roller and long roller are installed between outer ring and the inner ring, the mode that the short roller of every row and long roller are arranged is, one row be two short rollers be close to be contained in the centre, two grain length rollers are contained in two short roller both sides, an adjacent row is that two grain length rollers are close to when being contained in the centre, two short rollers are contained in two grain length roller both sides, every row installation that is staggered; Inwall at inner ring has several grease holes.

The advantage that the present invention compared with prior art has is: can effectively eliminate the harm that impulsive load and uneven load are brought; Effectively eliminated the raceway uneven wear; Bearing working life and reliability have been improved.
