Abstract
The invention discloses a combined bearing. The combined bearing comprises an inner sleeve and an outer sleeve. The combined bearing is characterized in that middle sleeves are arranged between the inner sleeve and the outer sleeve; rolling bodies are arranged between the outer sleeve and the middle sleeves; rolling bodies are arranged between the middle sleeves and the inner sleeve; the outer wall of the outer sleeve is perpendicular to the inner wall and is provided with taper; the inner wall of the inner sleeve is perpendicular to the outer wall and is provided with taper; the inner walls and the outer walls of the middle sleeves are provided with taper; the taper of the inner walls of the middle sleeves and the taper of the outer wall of the inner sleeve are the same; and the taper of the outer walls of the middle sleeves and the taper of the inner wall of the outer sleeve are the same. According to the combined bearing, the rolling bodies between the inner sleeve and the outer sleeve can be effectively overlapped, and stability is improved; when the rolling bodies are abraded, the inner sleeve and the outer sleeve can be naturally compressed; under the same condition, when one more middle sleeve is mounted, the bearing speed can be doubled compared with the original bearing speed; and the middle sleeves have the same specification, the multiple middle sleeves can be arranged according to the requirement, if one group of rolling bodies break down, other rolling bodies can continuously operate, and the service life of the bearing is effectively prolonged.
Description
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of combination bearing.
Background technology
With the fast development of machinery industry, bearing is also widely used, the cutter shaft bearing of vertical milling such as in woodworking machinery, its
Although lateral stressed, less very high to rotation speed requirements, because rotating speed is higher, Xian Su more is fast, and the plank for digging is smooth Jiu more,
Carpenter's slotting cutter shaft diameter in the market is most between 35 mm -40mm, but carpenter vertical milling of the rotating speed more than 20,000 turns
It is difficult to find.
In view of drawbacks described above, creator of the present invention passes through prolonged research and practice obtains the present invention finally.
The content of the invention
It is an object of the present invention to provide a kind of combination bearing, including；Inner sleeve and overcoat, it is characterised in that described is interior
Be provided with middle set between set and described overcoat, be provided with rolling element between described overcoat and described middle set, it is described in
Rolling element is provided between set and described inner sleeve, described outer casing outer wall inner vertical walls set tapered, in described inner sleeve
Wall perpendicular outer wall sets tapered, and described middle set inwall and outer wall are provided with taper, the taper of described middle set inwall with
The taper of described outer wall of inside race is identical, and the taper of described middle set outer wall is identical with the taper of outer casing inner wall；
Described middle set is provided with multiple, and specification is identical, can be superimposed as needed；
The taper of described outer casing inner wall, described middle set inwall and outer wall and described outer wall of inside race is identical, and its taper is in 20-
Between 30 degree；
Described outer casing inner wall, described middle set inwall and outer wall, the rolling element installation place of described outer wall of inside race are provided with
One annular vertical surface, described annular vertical surface is extended with the deep-slotted chip breaker matched with described rolling element.
Compared with the prior art the beneficial effects of the present invention are：The present invention covers in being provided between inner sleeve and overcoat, overcoat
Rolling element is provided between middle set, rolling element is provided between middle set and inner sleeve, outer casing inner wall sets tapered, outer wall of inside race
Set tapered, between 20-30 degree, the rolling physical efficiency so not only between inside and outside set is effectively overlapped its taper, increases its steady
It is qualitative, and inner-outer sleeve can be compressed naturally after rolling element weares and teares, and under similarity condition, set will be than original in installing one more
The bearing speed come is doubled, and middle set specification is identical, can be arranged as required to multiple, and such as one of which rolling element occurs event
Barrier, other rolling elements can also be continued to run with, and effectively extend the service life of bearing.
Brief description of the drawings
Fig. 1 is that combination bearing of the present invention is provided with the structural representation covered in；
Fig. 2 is that combination bearing of the present invention is provided with the structural representation covered in two；
Specific embodiment
Below in conjunction with accompanying drawing, the technical characteristic above-mentioned and other to the present invention and advantage are described in more detail.
As shown in the figure, there is provided a kind of combination bearing, including；Inner sleeve 3 and overcoat 4, in being provided between inner sleeve 3 and overcoat 4
Set 6, is provided with rolling element 5 between overcoat 4 and middle set 6, rolling element 5, the outer wall vertical of overcoat 4 are provided between middle set 6 and inner sleeve 3
Inwall sets tapered, and the inwall perpendicular outer wall of inner sleeve 3 sets tapered, and 6 inwalls of middle set and outer wall are provided with taper, middle set 6
The taper of inwall is identical with the taper of the outer wall of inner sleeve 3, and the taper of 6 outer walls of middle set is identical with the taper of the inwall of overcoat 4；Middle set 6 sets
Multiple is equipped with, and specification is identical；The taper of the inwall of overcoat 4, the inwall of middle set 6 and the outer wall of outer wall inner sleeve 3 is identical, and its taper exists
Between 20-30 degree；The inwall of overcoat 4, the inwall of middle set 6 and outer wall, the rolling element installation place of the outer wall of inner sleeve 3 are provided with an annular and hang down
Face directly, annular vertical surface is extended with the deep-slotted chip breaker matched with rolling element；In being provided between inner sleeve and overcoat cover, overcoat with
Rolling element is provided between middle set, rolling element is provided between middle set and inner sleeve, outer casing inner wall sets tapered, and outer wall of inside race sets
Taper is equipped with, between 20-30 degree, the rolling element installation place of the outer wall of inner sleeve 3 is provided with an annular vertical surface to its taper, annular
Vertical plane is extended with the deep-slotted chip breaker matched with rolling element；Rolling physical efficiency so not only between inside and outside set is effectively overlapped, and is increased
Its stability, and inner-outer sleeve can be compressed naturally after rolling element weares and teares, and under similarity condition, set will in installing one more
Doubled than original bearing speed, middle set specification is identical, multiple can be arranged as required to, such as one of which rolling element occurs
Failure, other rolling elements can also be continued to run with, if rolling element wear and tear, only need to change rolling element, without change it is inside and outside set and
Middle set, effectively extends the service life of bearing.
