Abstract
Double-row outer-ring-free full-complement cylinder roller bearing disclosed by the utility model, including inner ring（1）, completely be loaded on inner ring raceway cylindrical roller（2）And it is tightly placed in by the package of inner ring and the formed inner ring assembly of full-complement cylinder roller（3）The cylindrical roller is monoblock type biserial cylindrical structure and two row are intermediate with circumference slot structure, and the well width of the cylindrical roller is more unilateral big 0.05 ~ 0.1mm than the width of the inner ring centre rib and has the gap of 1 ~ 2mm between groove depth bottom and the centre rib outer diameter of the inner ring；The entire length of the cylindrical roller is equal to the sum of two raceway width of the inner ring and the inner ring centre rib width.It solves the problems such as big efficiency of assembly difficulty is low when assembly and intensity high bearing capacity is big compared with identical appearance dimensioned bearings.
Description
Technical field
The utility model belongs to cylinder roller bearing technical field, is primarily related to a kind of double-row outer-ring-free and completely fills cylinder
Roller bearing.
Background technology
The double-row full-complement cylinder roller bearing of well known canonical form is generally made of outer ring, inner ring and cylindrical roller.It is double
Row full-complement cylinder roller bearing can be packed into more rollers to the maximum extent due to being free of retainer, with conventional cylindrical roller
Bearing is compared, such bearing load carrying capacity is big, is suitable for the operating mode of slow-speed of revolution high radial load.But in certain specific occasions, by
Limitation in installation space and position, the double-row full-complement cylinder roller bearing of canonical form is due to space structure or bearing capacity
The low requirement that cannot be satisfied actual condition, to solve the limitation problem of installation space and position, it is desirable to provide one kind can reduce
Installation space can improve the novel double-row full-complement cylinder roller bearing of radial bearing capacity again.
Prior art generally use bearing saddle bore replaces the form of the outer ring of standard rolling bearing, forms the double-row full-complement without outer ring
Cylinder roller bearing, the technology roll the inner surface of bearing saddle bore instead of the outer ring rolling surface of standard rolling bearing, and by increasing
Sub- diameter improves the bearing capacity of bearing；Even so, the prior art is unrestricted due to biserial roller when bearing is assembled, and holds
It is easily scattered, the big efficiency of assembly difficulty is low and easily causes scuffing.
Utility model content
The utility model discloses a kind of double-row outer-ring-free full-complement cylinder roller bearing, to solve dress existing in the prior art
The problems such as low with the big efficiency of difficulty, reduces installation space but also the radial bearing capacity of raising to achieve the purpose that meet.
The utility model realizes that above-mentioned purpose adopts the technical scheme that：A kind of double-row outer-ring-free full-complement cylinder roller bearing
Including inner ring, completely it is loaded on the cylindrical roller of inner ring raceway and is tightly placed in by inner ring and the formed inner ring assembly of full-complement cylinder roller
Package, the cylindrical roller is monoblock type biserial cylindrical structure and two row are intermediate has circumference slot structure, the circle
The well width of column roller is more unilateral big 0.05 ~ 0.1mm than the width of the inner ring centre rib and groove depth bottom in the inner ring
Gap with 1 ~ 2mm between rib outer diameter；The entire length of the cylindrical roller is equal to two raceway width of the inner ring and institute
State the sum of inner ring centre rib width.
Further, the package is circular ring structure.
Further, two row cylindrical surfaces of the cylindrical roller have convexity repairing type structure.
Further：The groove edge of two row circumference slot structures of the cylindrical roller has chamfering structure.
The utility model is by being biserial monolithic construction, intermediate circumference direction fluting, slot and centre rib by roller designs
Axially and radially all there is certain gap, under identical appearance and size, than standard rolling bearing large carrying capacity, efficiency of assembling
Height, and during bearing working, when lubricating oil enters Bearing inner by outer ring or inner ring oilhole, roller medial launder and inner ring
The gap of rib ensure that the lubrication of roller end face and rib contact position, lubricating grease make rolling element working face obtain by this gap
Sufficient lubrication avoids bearing because failing caused by lack of lubrication.Chamfered is only made in roller medial launder edge, reduces
Unnecessary manufacturing procedure.
Description of the drawings
Fig. 1 is the utility model without outer ring full-complement cylinder roller bearing structural schematic diagram.
Fig. 2 is the monoblock type cylindrical roller schematic diagram of the utility model.
Fig. 3 is partial enlarged view at A in Fig. 1.
In figure：1, inner ring, 2, cylindrical roller, 3, package.
Specific implementation mode
The utility model is described in detail with reference to the drawings and specific embodiments：
As shown in Figure 1, the double-row outer-ring-free full-complement cylinder roller bearing described in the present embodiment includes by inner ring 1, is completely loaded on
The cylindrical roller 2 of inner ring raceway and being tightly placed in is made of the package 3 of inner ring and the formed inner ring assembly of full-complement cylinder roller.
In conjunction with Fig. 2, the cylindrical roller is monoblock type biserial cylindrical structure, and two row are intermediate with circumference slot structure and groove edge
With chamfering structure；In conjunction with Fig. 3, the well width a of the cylindrical roller it is more unilateral than the width b of the inner ring centre rib it is big by 0.05 ~
Gap c with 1 ~ 2mm between 0.1mm and groove depth bottom and the centre rib outer diameter of the inner ring；The entirety of the cylindrical roller
Length d is equal to the sum of two raceway width e of the inner ring and the inner ring centre rib width b.Two row cylinders of the cylindrical roller
Along the circumferential direction upper linear contact completely two roller surfaces loaded on the inner ring, the inner ring and the n completely filled are a respectively on shape surface
Cylindrical roller forms inner ring assembly.The package is circular ring structure and the fixed full dress roller with inner ring assembly of annulus endoporus
Outer rim simultaneously makes inner ring assembly not be scattered.
Further, 1 middle part of inner ring is provided with the hole of injection lubricator so that the cylindrical roller is contacted with inner ring
Place obtains sufficient lubrication.
Further, two row cylindrical surfaces of the cylindrical roller 2 have convexity repairing type structure.
Further, the package 3 is made by cardboard or polythene material.
Further, double-row outer-ring-free full-complement cylinder roller bearing assembly when by n cylindrical roller along two raceway of inner ring
Circumferencial direction completely fills arrangement, and the medial launder structure space that the cylindrical roller has can cross the centre rib of the inner ring, the two
Between existing gap can store certain lubricator, then package is tightly placed in the set of rollers of inner ring assembly again makes it will not
The sequence of sanqu songs within a particular musical mode.
