Preferably, the retainer is brass retainer.
A kind of taper roll bearing, including：Outer ring, inner ring, taper roller, retainer.Assembling process is：First by circular cone
Roller is fixed and is arranged in one entirety of formation on retainer, then entirety is assemblied between inner ring and outer ring.It will assembly when use
Good taper roll bearing is attached with bearing case, and bearing case hole is equipped in bearing case, will be along outer ring narrow end surface
Circumferential fixed annular rib card fits in the bearing case hole, and axially position is realized to bearing.Avoid taper roll bearing
Moved axially between bearing case, the friction for both continuing to cause and reduce making for taper roll bearing and bearing case
Use the service life.
Description of the drawings
In order to illustrate more clearly of the technical solution of the application, letter will be made to attached drawing needed in the embodiment below
Singly introduce, it should be apparent that, for those of ordinary skills, without creative efforts, also
It can be obtain other attached drawings according to these attached drawings.
Fig. 1 is a kind of structural schematic diagram of taper roll bearing provided by the embodiments of the present application；
Reference numeral is：The outer rings 1-, 2- inner rings, 3- taper rollers, 4- retainers, 5- ribs, 6- oil ducts, 7- boss.
Specific implementation mode
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, technical solutions in the embodiments of the present application is clearly and completely described, it is clear that described implementation
Example is only some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work should all belong to the application protection
Range.
It is a kind of structural schematic diagram of taper roll bearing provided by the embodiments of the present application referring to Fig. 1.
Specific embodiment of the present utility model is made a detailed explanation below according to attached drawing.
As shown in Figure 1, in the embodiment of the present application, a kind of taper roll bearing, including：Outer ring 1, inner ring 2, taper roller
3 and retainer 4, wherein：Taper roller 3 coordinates with retainer 4, is assemblied between outer ring 1 and inner ring 2, and along the narrow of outer ring 1
End face is circumferentially fixed to be equipped with cyclic annular rib 5, and rib 5 is vertical with the outer surface of outer ring 1.
Specifically, taper roller 3 is fixed first and is arranged in one entirety of formation on retainer 4, then entirety is assemblied in
Between outer ring 1 and inner ring 2.The taper roll bearing assembled is attached with bearing case when use, is set in bearing case
There is bearing case hole, will be fitted in the bearing case hole along the fixed card of annular rib 5 of the circumferential direction of 1 narrow end surface of outer ring, to axis
Hold realization axially position.It avoids moving axially between taper roll bearing and bearing case, continues the friction for causing the two
And reduce the service life of taper roll bearing and bearing case.
In the embodiment of the present application, it is provided with oil duct 6 on the lateral surface of outer ring 1, oil duct 6 and cyclic annular rib 5 is adjacent sets
It sets, cyclic annular rib 5 is connected in bearing case hole, and setting oil duct 6 can play the role of storing lubricating oil, when taper roller axis
It holds when in use, also rubs between outer ring 1 and bearing case hole, the lubricating oil being stored at this time in oil duct 6 then can be external
Circle 1 provides lubricating oil with bearing case hole, good to keep lubricating between outer ring 1 and bearing case hole so that outer ring 1 with
Frictional force between bearing case hole reduces.
In the embodiment of the present application, it is installed with annular boss 7 on the lateral surface of retainer 4, along the circumferential direction of retainer 4,
Boss 7 is contacted with the narrow end surface of outer ring 1.The medial surface of the retainer 4 opposite with 4 annular boss 7 of retainer and 2 lateral surface of inner ring
Contact, when inner ring 2 rotate, 4 medial surface of retainer and 2 lateral surface of inner ring formation boot state, the medial surface of retainer 4 with it is interior
The place for enclosing the contact of 2 lateral surfaces forms oil film, prevents the retainer 4 in rotation from skidding with inner ring 2, in addition, taper roll bearing
For detachable bearing, a portion is outer ring 1, and another part is inner ring 2, taper roller 3 and retainer 4, retainer 4
Lateral surface be arranged annular boss 7, when taper roll bearing when in use, boss 7 can make taper roll bearing operating more
Add steady.
In the embodiment of the present application, retainer 4 is brass retainer.At present retainer using steel plate punched retainer or
Steel post cage, but such retainer easily gets rusty, and declines so as to cause the rotating speed of bearing so that bearing uses the longevity
Life is reduced, and to avoid the problem that bearing, retainer gets rusty in wet condition, and the retainer 4 of the application is kept using brass entity
Frame, the mechanical strength that brass has high stretching slight, high, resistance to shock loads and good stability of the dimension, greatly increase bearing
Service life.
Since embodiment of above is that reference combination illustrates on other modes, have between different embodiments
There is an identical part, just to refer each other for identical, similar part between each embodiment in this specification.Herein no longer in detail
It illustrates.
It should be noted that in the present specification, the terms "include", "comprise" or its any other variant are intended to
