Description
Technical field
The utility model relates to a kind of improved tapered roller bearing, it is mainly used for the great types such as heavily loaded, axial load is big
It is mechanical.
Background technique
In some big machineries such as coal industry, mine industry, a large amount of use can not only bear radial load, but also can hold
By the tapered roller bearing of axial load, applying working condition feature: heavy duty, axial load is big, impact vibration is big, to bearing life
It is required that high, bearings market in repair service is very big, but market in repair service feature is that batch is small, and production cost is big.
Market in repair service feature is that batch is small, and the cost is relatively high for the technological equipment needed, and tapered roller bearing punching press is kept
Frame structure, for roller and retainer component to be fitted into inner ring, retainer needs first bulging, roller before bearing assembles fashionable dress roller
It being packed into retainer again by retainer contracting shape, contracting shape process is the part recovery straight line that will be led fortune roller bus and be deformed into curve,
It is practical to restore straight line completely.
Summary of the invention
According to defect of the existing technology, the purpose of the utility model is to provide a kind of improvement for being easily assembled and using
Tapered roller bearing.
In order to achieve the above objectives, the technology employed by the present utility model is a kind of improved tapered roller bearing, packet
Outer ring, inner ring, taper roller and retainer are included, the outer peripheral surface of the inner ring is equipped with the inner ring raceway of taper, the outer ring
Inner peripheral surface is equipped with the outer ring raceway of taper, and taper roller is arranged between inner ring raceway and outer ring raceway by retainer,
The inner ring has large-flange and small retaining ring, and the side of large diameter raceway is arranged in large-flange, and small retaining ring setting is rolled in small internal diameter
The side in road, the small retaining ring and inner ring are mutually indepedent.
Further, the small rib is removably attachable on inner ring.
Further, the large-flange is the flange for protruding from inner ring outer diameter raceway.
Further, the inner ring outer diameter is provided with the groove for installing small retaining ring, and small retaining ring is close to the side of taper roller
Section be it is angular, angular to be vertically arranged and match on one side with groove, angular another side is obliquely installed and the end with taper roller
Face matches.
Further, the small retaining ring and inner ring are positioned by lock ring.
Further, the large-flange is obliquely installed close to the side of taper roller and matches with the end face of taper roller
It closes.
Further, the retainer is pressing cage, and the fortune roller face of leading of retainer is plane.
The utility model has the following beneficial effects: the small stop portion of inner ring is made into a separate piece.Bearing assembly first will rolling
Son, retainer component are fitted into inner ring, then this separate piece of small retaining ring is packed into inner ring, this structure tapered roller bearing is assembling
When retainer do not have to bulging and contracting shape process, save bulging and two sets of assembling dies of contracting shape.And retainer will not be caused
Damage.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model,
Fig. 2 is small retaining ring enlarged drawing,
Fig. 3 is that retainer leads fortune face schematic diagram,
Fig. 4 transports roller bus schematic diagram to lead after bulging and contracting shape,
In figure: 1, inner ring, 2, outer ring, 3, taper roller, 4, retainer, 5, large-flange, 6, small retaining ring, 7, lead fortune
Face, 8, lead fortune roller bus, 9, vertical plane, 10, inclined surface.
Specific embodiment
It is practical new to this in the following with reference to the drawings and specific embodiments in order to be more clear the structure and function of utility model
Type is described further.
Usual tapered roller bearing internal ring is (double with large-flange (double raceway inner rings are centre rib) and small rib, large-flange
Raceway inner ring is centre rib) guide rolls, the function of small rib is to stop roller small end face, prevents roller and retainer from inner ring
In fall off and cause the sequence of sanqu songs within a particular musical mode, small rib interferes roller, retainer component to be fitted into inner ring when bearing assembles simultaneously for this, therefore assembly
In have retainer bulging and contracting shape process.Therefore the utility model provides a kind of improved tapered roller bearing.
Improved tapered roller bearing, including outer ring 2, inner ring 1, taper roller 3 and retainer 4, the periphery of the inner ring 1
Face is equipped with the inner ring raceway of taper, and the inner peripheral surface of the outer ring 2 is equipped with the outer ring raceway of taper, and taper roller passes through holding
Frame 4 is arranged between inner ring raceway and outer ring raceway, and the inner ring 1 has large-flange 5 and small retaining ring 6, and the setting of large-flange 5 exists
The side of small internal diameter raceway is arranged in the side of large diameter raceway, small retaining ring 6, and the small retaining ring 6 and inner ring 1 are mutually indepedent.It will
Inner-ring small flange part is made into a separate piece.Roller 3,4 component of retainer are first fitted into inner ring 1 by bearing assembly, then will be small
This separate piece of retaining ring 6 is packed into inner ring 1, this structure tapered roller bearing retainer 4 in assembly does not have to bulging and contracting shape process.
Save bulging and two sets of assembling dies of contracting shape.
Further, the large-flange 5 is the flange for protruding from inner ring outer diameter raceway.
Further, the inner ring outer diameter is provided with the groove for installing small retaining ring, and small retaining ring 6 is close to the side of taper roller
Section be it is angular, angular to be vertically arranged and match on one side with groove, angular another side is obliquely installed and the end with taper roller
Face matches.Small retaining ring inclined surface 10 has gap with taper roller end face.
Further, the small retaining ring and inner ring are positioned by lock ring.
Further, the large-flange 5 is obliquely installed close to the side of taper roller and matches with the end face of taper roller
It closes.
Further, the retainer 4 is pressing cage, and the fortune roller face 7 of leading of retainer is plane.Bearing assembled
Cheng Zhong, pressing cage so that retainer is led fortune roller bus 8 in bulging process some is become from straight line the song of approximate circular arc
Line, contracting shape process are the part recovery straight lines that will be led fortune roller bus and be deformed into curve, and reality can not restore straight line completely, and
It is curve shape shown in Fig. 4.The utility model pressing cage 4 leads fortune rolling without bulging and contracting shape process, retainer
Sub- face 7 is still ensured of a plane.
Small rib 6 can remove above-mentioned lock ring structure in a variety of forms with 1 positioning method of inner ring, can also be positioned by cooperation,
Or reversed cone angle structure positioning.
Listed above is only the most preferred embodiment of the utility model.Obviously, the utility model is not limited to above embodiments,
It is acceptable that there are many deformations.Those skilled in the art directly can export or associate from content disclosed by the utility model
All deformations, be considered as the protection scope of the utility model.
