Description
Technical field
This utility model relates to field of bearings, particularly to a kind of without outer ring cylinder roller bearing.
Background technology
Cylinder roller bearing without outer ring, widely applies on the gear of planetary reducer, and reductor is various machinery equipments
Required important device, it is desirable to bearing can meet the rotation that can ensure high-speed smooth under various working conditions, Er Qieda
To the long life-span；Cylinder roller bearing without outer ring, directly utilizing bore is bearing outer ring and outer raceway, reaches to simplify main frame
Design save limited space simultaneously, in limited space, use full roller designs, available maximum rated load,
Average increase payload about 15%-20% to be reached.
Commonly used cylinder roller bearing without outer ring, includes inner ring, and the outer ring surface of inner ring is provided with the raceway groove of annular,
It is covered with cylindrical roller in raceway groove, the outer ring surface of inner ring is positioned at roller both sides and further respectively has back-up ring, outside back-up ring, be additionally provided with card
Spring, fell apart to be unlikely bearing before being assembled on gear, needed bearing to be temporarily assemblied in one with a plastic wrapper
Rising, lose plastic wrapper, jump ring is stuck on the groove of bore when being assembled on gear, back-up ring is used for ensureing that roller will not axle
To play.But, the cylinder roller bearing without outer ring of this structure, its structure is complicated, assembling inconvenience.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, this utility model provides a kind of without outer ring circle
Post roller bearing, its simple in construction, the most convenient when assembling.
The technical solution of the utility model: a kind of without outer ring cylinder roller bearing, includes inner ring, on the outer ring surface of inner ring
It is provided with the raceway groove of annular, in raceway groove, is covered with cylindrical roller, it is characterised in that: it is respectively equipped with convex on the both sides end face of described roller
Platform, boss and the medial wall conflict of raceway groove, the outer ring surface of inner ring is positioned at raceway groove both sides and is arranged with retaining ring, retaining ring the most respectively
Also it is extended with for being pressed on locating ring on boss in raceway groove, the distance between trench bottom to inner ring central shaft and roller
Diameter sum is more than the external diameter of retaining ring.
Using technique scheme, can prevent roller from coming off by the retaining ring arranged, boss supports with the medial wall of raceway groove
Touch, be possible to prevent roller axial float, this cylinder roller bearing without outer ring, its simple in construction, assemble the most convenient；Raceway groove
Bottom more than the external diameter of retaining ring, so can avoid retaining ring to the diameter sum of the distance between inner ring central shaft and roller
Affect roller to rotate.
Further setting of the present utility model: annular positioning groove on the outer ring surface of described inner ring, described retaining ring
The curved flange that is provided with on inner ring surface, flange is embedded in locating slot.
Use above-mentioned further setting, be directly embedded in locating slot the locking of formation retaining ring and inner ring by flange and join
Closing, simple in construction, easy for installation, it is firm to position.
Further setting of the present utility model: described boss is coaxially disposed with roller.
Use and above-mentioned further arrange so that bearing is more steady when rotating.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment；
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, one, without outer ring cylinder roller bearing, includes inner ring 1, and the outer ring surface of inner ring 1 is provided with ring
The raceway groove 2 of shape, is covered with cylindrical roller 3, the both sides end face of described roller 3 is respectively equipped with boss 4 in raceway groove 2, described is convex
Platform 4 is coaxially disposed with roller 3, boss 4 and the medial wall conflict of raceway groove 2, the outer ring surface of inner ring 1 is positioned at raceway groove 2 both sides and also divides
Not being arranged with retaining ring 5, retaining ring 5 is also extended with for being pressed on locating ring 51 on boss 4, in raceway groove 2 bottom raceway groove 2 extremely
The diameter b sum of distance a between inner ring 1 central shaft and roller 3 is more than the external diameter c of retaining ring 5.
Can prevent roller 3 from coming off by the retaining ring 5 arranged, boss 4 and the medial wall conflict of raceway groove 2, it is possible to prevent rolling
Son 3 axial floats, this cylindrical roller without outer ring 3 bearing, its simple in construction, assemble the most convenient；To inner ring bottom raceway groove 2
The diameter sum of the distance between 1 central shaft and roller 3, more than the external diameter of retaining ring 5, so can avoid retaining ring 5 impact rolling
Son 3 rotates.
In this utility model specific embodiment, annular positioning groove 11 on the outer ring surface of described inner ring 1, described retaining ring
The curved flange 52 that is provided with on the inner ring surface of 5, flange 52 is embedded in locating slot 11, is directly embedded in locating slot 11 by flange 52
Forming retaining ring 5 to coordinate with the locking of inner ring 1, simple in construction, easy for installation, it is firm to position.
