Description
Technical field
The utility model relates to a kind of bearing, especially a kind of double-row full-complement cylinder roller bearing.
Background technique
Double-row full-complement cylinder roller bearing is a kind of no retainer, and expires the bearing of dress roller, is protected having with tradition
The bearing for holding frame is compared, and under equal volume, has higher bearing capacity.Double-row full-complement cylinder roller axis in the prior art
It holds, generally includes several rollers, outer ring, the inner ring being spliced by two lassos and two lassos are fixed together
Fastener, described two lassos include the rib positioned at its two sides, are formed between two ribs and set for roller slip
The raceway set is provided between two raceways and is formed with the roller of two sides the centre rib of axial limiting on the outer ring,
Described two lassos are formed with the mounting portion for fastener installation when splicing.
But the prior art after needing to position bearing outer ring, carries out two lassos during assembly
Clamping position prevents two lassos from deviating from outward, fastener is placed in mounting portion position later, by rolling wheel make its at
The process of type, assembly is cumbersome, and technique requires height, and bearing is during use, and two lassos are easy to happen opposite position
It moves, causes two opposite end faces of lasso to be worn, influence the service life of bearing.
Utility model content
In view of the deficiencies of the prior art, the utility model provide it is a kind of assembly it is simpler, avoid sending out between two lassos
Raw abrasion, the double-row full-complement cylinder roller bearing that the service life is longer.
To achieve the above object, the utility model provides a kind of double-row full-complement cylinder roller bearing, includes inner ring, outer
Circle, the inner ring is spliced by the first lasso and the second lasso, and the first lasso and the second lasso are formed with outer ring respectively
Raceway, roller has been filled in the raceway, and one end of first lasso towards the second lasso is circumferentially evenly equipped with several clamps, institute
It states the second lasso and corresponds to clamp and be provided with the card slot that formed can be axially engaged by clamping, first lasso is in adjacent clamp
Between be provided with the first through slot, second lasso is provided with the second through slot between adjacent card slot, the card slot and second logical
Slot is connected, and the clamp, which can be axially inserted into along the second through slot and circumferentially rotate to card slot, is mutually clamped position, and described first
Fastener is embedded in through slot and the second through slot.
By adopting the above technical scheme the advantages of, is: can lead to the clamp on the first lasso by second on the second lasso
Slot is axially inserted into, and later circumferentially rotates clamp into card slot, so that the two is formed the cooperation of clamping, is passed through the card of clamp and card slot
Connecing cooperation makes the first lasso and the second lasso form fixation between the two, need compared with prior art respectively to the outer ring of bearing with
And two lassos are positioned, it, can be by the clamp that is arranged on the first lasso and setting the in assembling process
The axial clamping engagement between the two of card slot on two lassos, prevents the first lasso from deviating from outward with the second lasso, without progress
Additional fixation, assembling process are simpler.Since the first through slot and the second through slot are separately positioned on adjacent clamp and card
Between slot and fastener is inlaid in the first through slot and the second through slot, to make two lassos in the use process of bearing
Rotation is consistent, and two opposite end faces of lasso is avoided to wear.
The utility model can be further arranged to: the fastener both ends have been bent to form clamping part, first lasso
The both ends opposite with the second lasso are separately provided for the groove of accommodating fastener both ends clamping part.
By being further arranged, fastener is flush-mounted in inner ring, the retained part being bent to form by fastener in both ends
It is not placed in the groove at the first lasso both ends opposite with the second lasso, the first lasso and the second lasso is formed and clamped, is prevented
First lasso is deviate from outward with the second lasso, enhances antiwhip, and needs to put fastener compared with prior art
It is placed in mounting portion position, its molding is made by rolling wheel, can in addition be made respectively, be assembled, further decreased later
Technique requirement, simplifies assembling process.
The utility model can be further arranged to: the fastener is towards smooth between the end face and inner ring internal perisporium in axle center
Transition connection.
By being further arranged, makes in bearing use process, formed and fitted between fastener and inner ring internal perisporium, prevented
It is vibrated during the rotation of two lassos, further avoids two opposite end faces of lasso and wear.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of the utility model embodiment；
Fig. 2 is another cross-sectional view of the utility model embodiment；
Fig. 3 is the schematic diagram of the second lasso in the utility model embodiment；
Fig. 4 is the schematic diagram of the first lasso in the utility model embodiment.
Specific embodiment
A kind of embodiment of double-row full-complement cylinder roller bearing of the utility model is as shown in Figs 1-4: a kind of double-row full-complement circle
Column roller bearing includes inner ring 2, outer ring 1, and the inner ring 2 is spliced by the first lasso 21 and the second lasso 22, and first
Lasso 21 and the second lasso 22 are formed with raceway 3 with outer ring 1 respectively, and roller 4, first lasso have been filled in the raceway 3
21 are circumferentially evenly equipped with several clamps 211 towards one end of the second lasso 22, and the corresponding clamp 211 of second lasso 22 is provided with energy
Enough formed card slots 221 being axially engaged by clamping, first lasso 21 are provided with the first through slot between adjacent clamp 211
212, second set of 22 circle is provided with the second through slot 222, the card slot 221 and the second through slot 222 between adjacent card slot 221
It is connected, the clamp 211, which can be axially inserted into along the second through slot 222 and circumferentially rotate to 221 phase of card slot, is clamped position, institute
It states in the first through slot 212 and the second through slot 222 embedded with fastener 5.5 both ends of fastener have been bent to form clamping part 51,
The both ends of first lasso 21 and the second lasso 22 back are separately provided for the groove of accommodating 5 both ends clamping part 51 of fastener
6, in the present embodiment, interference fit is formed between the clamping part 51 and groove 6, prevents fastener 5 from moving.It is described
Fastener 5 is connected smoothly towards between 2 internal perisporium of end face and inner ring in axle center.
Above example, only one kind of the utility model preferably specific example, those skilled in the art are practical new at this
The usual variations and alternatives carried out in type technical proposal scope are included in the protection scope of the utility model.
