Abstract
The utility model relates to a symmetrical spherical roller bearing, in particular to a novel structural symmetrical spherical roller bearing which is used on a spindle of a large ball mill. The utility model comprises an outer ring with an inner spherical surface raceway, an inner ring with a middle retaining edge, and two double half entity cages and two groups of spherical rollers. The utility model is characterized in that the outer surface of the outer ring is a spherical surface. The utility model solves the deficiencies of prior art and is suitable for the spindle of the ball mill. The utility model not only has long service life, but also has the function of double centering.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, especially relates to a kind of selfaligning roller bearing that is used for the new structure on the large-size ball mill main shaft.
Background technique
The selfaligning roller bearing of using on the present large-size ball mill main shaft, because the main shaft of pebble mill is bigger, rotating speed is lower, moment of torsion is big, and amount of deflection is big, and is bad with the existing bearing aligning performance, make the pebble mill main shaft bearing reduce the working life of also having reduced the pebble mill main shaft simultaneously working life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of long service life that is applicable to that the pebble mill main shaft is used is provided, and has the selfaligning roller bearing of the new structure of dual aligning effect.
The utility model is realized in the following way:
A kind of selfaligning roller bearing of new structure comprises the outer ring of an internal spherical surface raceway, the inner ring of a band centre rib, and two two half solid cages and two groups of spherical rollers, it is characterized in that: the outer surface of described outer ring is a sphere.
The utility model is with the inside and outside sphere that all is processed as of the outer ring of existing selfaligning roller bearing, such structure not only can compensate because of machine cut processing or install bad cause initially to neutral error, can also eliminate podiod not being rung that the long main shaft amount of deflection of pebble mill brings greatly, has dual aligning performance, not only reduced the spoilage of pebble mill main shaft bearing, and improved the working life of pebble mill main shaft bearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of selfaligning roller bearing of new structure, the outer ring 1 that comprises an internal spherical surface raceway, the inner ring 2 of a band centre rib, two two half solid cages 3 and two groups of spherical rollers 4, as shown in Figure 1: the outer surface of outer ring 1 is processed as sphere, like this bearing outer ring 1 in, be sphere outward, thereby can compensate because of machine cut processing or install bad cause initially to neutral error, can also eliminate podiod not being rung that the long main shaft amount of deflection of pebble mill brings greatly, in the outer ring 1, be sphere outward, make this bearing have dual aligning performance, not only reduced the spoilage of pebble mill main shaft bearing, and improved the working life of pebble mill main shaft bearing.
