Abstract
The invention relates to a second-generation tapered roller bearing of the speed reducer industry. The second-generation tapered roller bearing comprises an inner ring, an outer ring, rollers and a retainer; through the retainer, the rollers are arranged in a pocket hole of the retainer; and the rollers and the inner ring which are connected with each other are packed into double rows of raceways of the outer ring. Compared with the prior art, the second-generation tapered roller bearing provided by the invention has the advantages of compact structure, convenience for assembling, good lubrication effect and long service life.
Description
Technical field
The present invention relates to a kind of bearing, especially relate to a kind of speed reducer industry two generations tapered roller bearing.
Background technique
At present speed reducer is all to adopt worm gear structure, the bearing in reduction gears of use the most wide selection be single-row tapered roller bearing or back-to-back paired tapered roller bearing, because spacer ring machining accuracy problem affects installation precision.What therefore, relatively have challenge in speed reducer industry is bearing application.All can be in the running environment of heavy load, impulsive load, high and low rotating speed, high temperature and high pollution at speed reducer key position bearing.Bearing in speed reducer equipment, can be described as the heart of speed reducer, has caused the demand to high-performance bearing just because of the running environment of this harshness.Only have high performance bearing can guarantee speed reducer also continuous operation to greatest extent under exceedingly odious environment, help client to reduce costs the creation of value thereby reduce dead time.
Summary of the invention
Object of the present invention be exactly provide in order to overcome the defect that above-mentioned prior art exists a kind of compact structure, easy for installation, lubricated fully, long service life for speed reducer industry two generations tapered roller bearing.
Object of the present invention can be achieved through the following technical solutions:
A kind of speed reducer industry two generations tapered roller bearing, is characterized in that, comprise inner ring, outer ring, roller and retainer, described retainer is arranged on roller in its pocket hole, and after being connected with inner ring, packs in the lump in the biserial raceway of outer ring.
Described outer ring is flanged structure, and is provided with the tank filler sleeve being communicated with inner ring.
Described inner ring is provided with two, and two interior ring outer walls form back-to-back roller path structure.
Described outer ring is the outer ring that surface hardening rear spring steel is made.
Compared with prior art, the present invention has the following advantages:
1, outer ring is flanged structure, and is designed with tank filler sleeve, makes structure compacter, easy for installation, fully lubricated.
2, two ring outer walls in each and every one form back-to-back roller path structure, in the biserial raceway of outer ring, have solved that single conical bearing is back-to-back affects installation precision because of the spacer ring machining accuracy problem between inner ring with retainer assembled.
3, outer loop material adopts spring steel, and surface hardening can be handed at shock and vibration or for a long time under stress and be used and improve working life.
4, the load of biserial roller distributes and improves, thereby reduces wear, and increases the service life.
5, replace turbine and worm structure speed reducer, at home and abroad maintain the leading position.Product is from design theory to specially all having uniqueness, novelty, creativeness and feasibility to research
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of speed reducer industry two generations tapered roller bearing, comprises inner ring 2, outer ring 1, roller 3 and retainer 4, and described retainer 3 is arranged on roller in its pocket hole, and after being connected with inner ring 2, packs in the lump in the biserial raceway of outer ring 1.
Described outer ring 1 is flanged structure, and is provided with the tank filler sleeve being communicated with inner ring 2.Described inner ring 2 is provided with two, and two inner ring 2 outer walls form back-to-back roller path structure.The outer ring that described outer ring 1 is made for surface hardening rear spring steel.Described bearing will form certain moment of torsion.
