Abstract
The utility model relates to a two-way thrust tapered roller bearing, which comprises a central shaft ring, races, a retainer, tapered rollers and a spacing ring, wherein after the tapered rollers are mounted in the retainer, the retainer is mounted between the central shaft ring and the races; the central shaft ring is mounted between the two rows of tapered rollers; the races are mounted on the outer side of the retainer; and the spacing ring is arranged between the two races. Compared with the prior art, the two-way thrust tapered roller bearing has the advantages of high machining precision, long service life, high safety, compact structure and the like.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of bidirectional thrust tapered roller bearing.
Background technique
At present, in the milling train industry, common employing two cover tapered roller thrust bearings have following shortcoming: will adjust bearing clearance when 1, installing; 2, the bearing installation and maintenance are more difficult.
The model utility content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of machining accuracy is high, the life-span long, the bidirectional thrust tapered roller bearing of safe, compact structure.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of bidirectional thrust tapered roller bearing, it is characterized in that, comprise middle blowout patche, seat ring, retainer, tapered roller and spacer ring, described tapered roller is packed into after retainer, retainer is contained between middle blowout patche and seat ring, described middle blowout patche is contained between two row tapered rollers, and described seat ring is contained in outside retainer, and described spacer ring is located between two seat rings.
Described middle blowout patche both sides are provided with two row raceways, and the inner side surface of described tapered roller is located in raceway.
Described seat ring is provided with for the tilted slideway that loads tapered roller, and is provided with rib at the tilted slideway end.
Described retainer is copper cage, and this copper cage is by keeping stand and retainer lid to form, and described retainer lid is connected with keeping stand by the steel screw.
Described spacer ring side is provided with oilhole, and lubricant oil can pass through from its oilhole.
The plain line in described tapered roller surface adopts the correction of the flank shape of arc generatrix convexity.
Compared with prior art, the utlity model has following advantage:
1, machining accuracy is high;
2, life-span length, safe, each seat ring has an inclined races, an inclination rib;
3, lubricate, the spacer ring side is provided with oilhole, and lubricant oil can pass through from its oilhole;
4, compact structure replaces for the two single-row tapered roller thrust bearings of cover.
5, be convenient to installation and can be used on various milling trains, made on the milling train industry a new step, reach domestic and international advanced level.
