Description
Technical field
It the utility model is related to a kind of bearing, and in particular to a kind of top load, hard sealing, full-complement cylinder roller can be achieved
Bearing.
Background technology
At present four row cylindrical bearings of conventional structure outer ring band centre rib, rolling element by copper cage do guiding with every
From, and all there is retainer certain deck-siding to ensure its intensity, this beam just reduces the roller number of bearing, bearing
Bearing capacity declines, while also increases the abrasion between rolling element surface and retainer pocket hole, reduces service life.In addition,
There is intrusion of the impurity such as cooling water, oxide skin, dust to bearing chamber in many work-yards such as milling train, cause lubrication to be destroyed,
Abrasion aggravation.
Therefore, middling speed, heavy duty, abrasion it is larger, sealing it is bad in the case of, how to improve large cylindrical roller bearing
Bearing capacity, abrasion is reduced, prevents the intrusion of water, impurity to bearing, is urgent problem to be solved.
Utility model content
In view of the shortcomings of the prior art, the utility model aims to provide a kind of top load, hard sealing, full-complement cylinder roller axle
Hold, middling speed, heavy duty, abrasion it is larger, sealing it is bad in the case of improve large cylindrical roller bearing bearing capacity, reduce mill
Damage, prevents the intrusion of water, impurity to bearing.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of top load, hard sealing, full-complement cylinder roller bearing parts mainly by outer ring, inner ring, roller, self-lubricating every
From pad, cage ring and spring sealed circle composition, roller is completely filled between the inner ring and outer ring, is isolated between roller by self-lubricating
Pad isolation.Roller rotates by inner ring and outer ring raceway guide rolls.The self-lubricating isolating pad is made up of self-lubricating material, rises
To playing self-lubricating.
Cage ring end face has been uniformly distributed multiple straight pins, and interporal lacuna is matched somebody with somebody in the roller of each straight pin and correspondence position
Close, play a part of fixed roller.Cage ring is connected on the internal diameter of outer ring flange by spring sealed circle, the internal diameter of outer ring flange
Provided with groove, spring sealed circle coordinates with groove for gap, so as to which cage ring is guided by outer ring flange internal diameter gap.
After cage ring installation, outer ring, roller, self-lubricating isolating pad, cage ring, spring sealed circle form one outer group
Part, ensure not fall roller when outer component and housing assemble.The spring sealed circle serves the effect sealed firmly, has both stopped cold
But the entrance of the foreign matter such as water, impurity, oxide skin, dust, lubricating oil is kept not to be lost in again.
Further, roller is divided into long roller and short roller, and the long roller and short roller are staggered.It can so make
It is consistent to the even wearing of raceway to obtain two row rollers.
Further, the spring sealed circle is the helical structure made of spring steel.
Further, isolated between all rollers by self-lubricating isolating pad, roller is between each other formed with 2-3 millimeters
Gap.Without friction between roller.
Further, the external diameter of the cage ring and internal diameter have been respectively mounted spring sealed circle.
The beneficial effects of the utility model are：
1st, the quantity of increase roller is can aid in by removing the retainer in traditional bearing structure, removes and is kept off in outer ring
While can aid in increase roller length, so as to maximally utilise bearing interior space, the bearing capacity of bearing is improved.
2nd, by mixing spring sealed circle, can internally playing gear, oil stream does not go out, external water, dust, oxide skin, impurity enter
The effect do not gone, reliability, permanence that increase bearing uses are realized, and can also be by using steel cage ring and spring
Sealing ring realizes resistance to less than 450 DEG C of high temperature, realizes and is widely applied in milling train, mine and cement machinery field.
3rd, conventional bearings retainer majority is manufactured with brass, using structure of the present utility model, just saves brass holding
The rare metal of frame.
4th, self-lubricating isolating pad coefficient of friction is low, and mutually abrasion is few, and has self-lubricating function.
The utility model bearing, be computed, the dynamic load of bearing improve 15% or so, service life can improve 60% with
On.

Embodiment
Below with reference to accompanying drawing, the utility model will be further described, it is necessary to which explanation, the present embodiment is with this skill
Premised on art scheme, detailed embodiment and specific operating process are given, but the scope of protection of the utility model is not
It is limited to the present embodiment.
As shown in Figure 1-2, a kind of top load, hard sealing, full-complement cylinder roller bearing, mainly by outer ring 1, inner ring 2, roller
3rd, cage ring 4, spring sealed circle 5, self-lubricating isolating pad 6 form, and are isolated between roller 3 by self-lubricating isolating pad 6.
Multiple straight pins are uniformly distributed on the end face of cage ring 4, each straight pin gap is matched with the roller of correspondence position
Endoporus, what is shown in the present embodiment all sets cage ring 4 for Biserial cylindrical roller bearing, the two sides of each column roller.Isolation
Circle 4 is connected on the internal diameter of the rib of outer ring 1 by spring sealed circle 5, and the internal diameter of the rib of outer ring 1 is provided with groove, described spring sealed
Circle 5 coordinates with groove for gap, and cage ring is guided by the internal diameter gap of outer ring flange.The external diameter of cage ring 4 and the annular groove of internal diameter
Inside be respectively mounted spring sealed circle 5, spring sealed circle 5 serves the effect sealed firmly, both stopped cooling water, impurity, oxide skin,
The entrance of the foreign matters such as dust, lubricating oil is kept not to be lost in again.It is outer ring 1, roller 3, cage ring 4, spring sealed after cage ring installation
Circle 5, self-lubricating isolating pad 6 form an outer component, can ensure that roller will not drop out when outer component assembles with housing.
During using more line column roller structures, roller can be divided into two kinds of rollers of long roller and short roller, and long rolling
Sub and short roller is staggered, so that two row rollers are consistent to the even wearing of raceway.
All rollers 3 are isolated by self-lubricating isolating pad 6, gap of the roller each other formed with 2-3 millimeters so that roller
Between without friction.
The contact surface of cage ring, spring sealed circle, bearing outer ring, inner ring between them has a small amount of gap.
Spring sealed circle is the helical structure made of spring steel, as shown in Figure 3.
Said structure is applied to single-row, biserial, four-line column roller bearing.
For those skilled in the art, technical scheme that can be more than and design, make various corresponding
Change and deformation, and all these change and deformation should be construed as being included in the utility model claims protection domain it
It is interior.
