Abstract
The invention relates to a bidirectional-thrust tapered roller bearing. The bidirectional-thrust tapered roller bearing comprises a middle shaft ring, seat rings, holding frames, tapered rollers and a space ring, wherein after the tapered rollers are mounted in the holding frames, the holding frames are mounted between the middle shaft ring and the seat rings, the middle shaft ring is mounted between the two rows of tapered rollers, the seat rings are mounted on the outer sides of the holding frames, and the space ring is arranged between the two seat rings. Compared with the prior art, the bidirectional-thrust tapered roller bearing has the advantages of high machining precision, long life, high security, compact structure and the like.
Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of bidirectional thrust tapered roller bearing.
Background technique
At present, in milling train industry, tapered roller thrust bearing is overlapped in common employing two, has following shortcoming: while 1, installation, will adjust bearing clearance; 2, bearing installation and maintenance are more difficult.
Summary of the invention
Object of the present invention be exactly provide in order to overcome the defect 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.
Object of the present invention 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 packs 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 retainer outside, 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 the tilted slideway for loading tapered roller, and is provided with rib at 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 steel screw.
Described spacer ring side is provided with oilhole, and lubricant oil can pass through from its oilhole.
The described plain line in tapered roller surface adopts the correction of the flank shape of arc generatrix convexity.
Compared with prior art, the present invention has the following advantages:
1, machining accuracy is high;
2, life-span length, safe, each seat ring has an inclined races, an inclination rib;
3, lubricate, spacer ring side is provided with oilhole, and lubricant oil can pass through from its oilhole;
4, compact structure, replaces for the single-row tapered roller thrust bearing of two covers.
5, be convenient to installation and can be used on various milling trains, made in milling train industry a new step, reach domestic and international advanced level.
