Abstract
The invention relates to a widened tapered roller bearing for a stone sawing machine. The widened tapered roller bearing for the stone sawing machine comprises an outer ring, a bearing holder and an inner ring which are arranged in sequence from outside to inside; a tapered roller is arranged in a groove of the bearing holder; the tapered roller rolls in a tapered roller way which is formed by matching an inner ring roller way outside the inner ring with an outer ring roller way inside the outer ring; the outer ring, the inner ring and the tapered roller of the beating are each of a widened structure. Compared with the prior art, the widened tapered roller bearing for the stone sawing machine has the advantages of high bearing capacity, long service life and the like.
Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of widened tapered roller bearing for stone sawing machine.
Background technique
Tapered roller bearing belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway.This class bearing is divided into single-row, that biserial and four-row tapered roller bearing etc. are different structural type by the columns of filled roller.Single-row tapered roller bearing can bear radial load and single direction axial load.When bearing bears radial load, an axial thrust load will be produced.At present, cutting industry middle (center) bearing is vitals in stone sawing machine, paired mounting is on main shaft, the impact of high capacity and vibration can be subject to during use, usually the tapered roller bearing adopted is used for bearing based on radial force, but often limit by standard design boundary dimension, meet carrying needs with many cover bearings, install, maintenance is very difficult again.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of widened tapered roller bearing for stone sawing machine is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of widened tapered roller bearing for stone sawing machine, it is characterized in that, comprise the outer ring that ecto-entad sets gradually, bearing cage and inner ring, also tapered roller is provided with in the groove of described bearing cage, the inner ring raceway of described tapered roller in inner ring outside matches with the outer ring raceway of inside, outer ring in the tapered raceway that formed and rolls, the outer ring of this bearing, inner ring and tapered roller all adopt widened structure, add outer ring width, inner race width and the overall width after assembling, expand bearing tolerance scope diametrically, improve the load-carrying properties of bearing.
Described tapered roller is multiple, and is evenly distributed in the groove of bearing cage.
Described tapered roller adopts logarithmic curve convexity correction of the flank shape structure.
Described outer ring lengthens 20 ~ 30mm.
Described inner ring lengthens 20 ~ 30mm.
Described assembling rear bearing lengthens 20 ~ 30mm.
Compared with prior art, the present invention has the following advantages:
1, bearing capacity is strong: owing to have employed widened Internal and external cycle and roller, and the radial force that bearing can be born and axial force promote all greatly, thus adds bearing load ability and improve bearing impact resistance.
2, long service life, roller adopts logarithmic curve convexity relieved end roller, extends working life.
