Description
Technical field
The utility model belongs to bearing roller technical field, more particularly to a kind of spherical roller.
Background technology
Spheric roller bearing be in the inner ring and raceway for having two raceways between the outer ring of sphere, assemble cydariform（Ball
Face）The bearing of roller, it has two row rollers, substantial radial load, while can also bear the axial load of either direction.
There is high radial capacity, especially suitable for being worked under heavy duty or oscillating load, but purely axial load can not be born.Such axle
Bearing outer-ring raceway is spheric, therefore its aligning performance is good, can compensating coaxial degree error.
But found in the long-term course of work, because spherical roller is solid construction, roller often will in quenching
There is the defects of hardness inequality, soft spots, mechanical performance of the roller on whole section of diameter is mutually far short of what is expected, and the life-span substantially reduces；
In addition, be sliding contact friction between existing cylindrical roller and retainer, due to retainer, its internal lubricating oil
Easily flow out, it is insufficient so as to cause to lubricate.
The content of the invention
In order to solve problem present in background technology, the purpose of this utility model is to provide a kind of spherical roller.
In order to realize foregoing invention purpose, the utility model uses technical scheme as described below：
A kind of spherical roller, including roller body, the central through hole being provided centrally with vertically of roller body, in roller
A lubricating arrangement is respectively arranged with the both ends of the surface of body, lubricating arrangement includes circular lubrication block and is arranged on lubrication block one end
Connecting portion composition at the center of face, connecting portion are connected in the Single port of the central through hole, and connecting portion is in open at both ends
Columnar structures, some lubrication channels radially are along the circumferential direction uniformly arranged in block lubricating, the one of lubrication channel
End intersects at the center of lubrication block and communicated, connecting portion through the circumference side of lubrication block, the other end of all lubrication channels
Hollow cavity be connected with lubrication channel.
Further, the hollow cavity of connecting portion is communicated at the center of lubrication block and is connected with all lubrication lubrication channels
It is logical.
Further, the central through hole of the connecting portion and roller body is connected by being interference fitted.
Further, external screw thread is provided with the periphery of connecting portion, is set on the madial wall of roller body central through hole
There is internal thread, be closely connected with roller body by the cooperation connecting portion of internal and external screw thread.
Further, the lubrication channel is at least provided with one.
Further, it is provided with counterbore at the center of the other end of lubrication block.
Because using above-mentioned technical proposal, the utility model has following superiority：
1st, the utility model is by roller body by being set to hollow structure, ensure that roller body entirety through hardening, and hardness is equal
Even consistent, the mechanical performance of whole cross section is consistent, avoids the grinding burn of end face, effectively increases roller service life；
2nd, by setting lubricating arrangement spherical roller of the present utility model to obtain effectively lubricating at work, carry
High service life.

Fig. 3 is the structural representation of lubrication another angle of block；
In figure：1st, roller body；2nd, central through hole；3rd, block is lubricated；4th, connecting portion；5th, lubrication channel；6th, counterbore.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
As shown in Figure 1, 2, a kind of spherical roller, including roller body 1, roller body 1 are provided centrally with vertically
Central through hole 2, is respectively arranged with a lubricating arrangement in the both ends of the surface of roller body 1, and lubricating arrangement includes circular lubrication block 3
Formed with the connecting portion 4 being arranged at lubrication block 3 end face center, connecting portion 4 is connected to the Single port of the central through hole 2
Interior, connecting portion 4 is the hollow columnar structures of open at both ends, and some have along the circumferential direction been uniformly arranged along footpath in lubrication block 3
To lubrication channel 5, one end of lubrication channel 5 is intersected through the circumference side of lubrication block 3, the other end of all lubrication channels 5
At the center of lubrication block 3 and communicate, the hollow cavity of connecting portion 4 is connected with lubrication channel 5.
The effect that block 3 is lubricated in the utility model is in order to facilitate the lubrication of roller body 1 at work, is somebody's turn to do to realize
Effect is, it is necessary to the hollow cavity of connecting portion 4 is connected with the lubrication channel 5 inside roller body 1, in the present embodiment specifically
For, i.e. the hollow cavity of connecting portion 4 is communicated at the center of lubrication block 3 and is connected with all lubrication channels 5.
Lubrication principle of the present utility model is：Roller body after the process, injects into the central through hole of roller body
Lubricating oil, then central through hole is sealed by connecting lubrication block respectively in roller body both ends of the surface, roller body is working
In rotation, lubrication is flowed into the inner chamber of connecting portion by central through hole, then flows into lubrication channel again also with rotation, lubricating oil soon
It is interior, finally go out from lubricating fast circumference surface current, and then flow on the raceway between the inside and outside circle of bearing and roller body it is outer
On surface, the lubrication to Bearing inner is thus realized.
In the present embodiment, in order to realize the close connection of connecting portion and roller body, the connecting portion and roller body
Central through hole pass through be interference fitted connection.
As shown in figure 3, be provided with counterbore 6 at the center of the other end of lubrication block, the design of counterbore be for the ease of
The installation of follow-up roller body and retainer.
Embodiment two, the present embodiment and the difference of embodiment one are：Connecting portion 4 and the attachment structure of roller body 1
Difference, specifically, in this embodiment, external screw thread is provided with the periphery of connecting portion 4, in roller body central through hole
Internal thread is provided with madial wall, is closely connected with roller body 1 by the cooperation connecting portion 4 of internal and external screw thread.
In this embodiment, when the serious wear of roller body 1 needs to change, it is only necessary to change roller body, and moisten
Sliding block need not be changed.
In embodiment one, two, the lubrication channel 5 is at least provided with one.
In addition, in embodiment one, two, connecting portion 4 is to be detachably connected with the attachment structure for lubricating block 3, or
Molding structure is integrally machined, preferably, connecting portion uses with lubrication block is integrally machined shaping.
