Description
Technical field
The present invention relates to the technical field of bearing, especially relate to a kind of rolling bearing structure.
Background technology
Existing rolling bearing structure is made up of bearing outer ring, bearing inner race, rolling element and retainer.
Rolling bearing, during life-time service, has dirt and enters bearing clearance, cause bearing accuracy to reduce, reach not
To use required precision, solve problems have two kinds, a kind of is the bearing more renewed, one be bearing is dismantled into
Row cleans.Traditional dismounting mode is divided into hammering method, pull-out method, pushing method, heat to tear method open, and conventional dismounting mode is first to will warm up
The machine oil oil can of about 100 DEG C is cast on bearing to be torn open, after race ring expanded by heating, i.e. can use puller by bearing
Circle pull-out, then splits out rolling element from retainer, and last bearing outer ring separates with retainer.
During bearing removal, the machine oil oil can of about 100 DEG C need to be cast on bearing to be torn open, in the process
There is great potential safety hazard, additionally need to treat race ring expanded by heating, there are direct relation the size of expansion and time, for not
With bearing, the size of swell increment also differs, during manual operation, is difficult to management and control for the different bearing time, is heated
Time is too short, then swell increment is inadequate.If heated time is long, then swell increment can be caused excessive or machine oil cooling, increase dismounting
Difficulty.Additionally during pull-out bearing inner race, owing to bearing surface is covered with machine oil, instrument is easily caused to be beaten when pull-out
Sliding, thus cause bearing to be injured.
It is therefore desirable to a kind of rolling bearing structure of design, it is achieved it is readily disassembled in Renewal process cleaning, it is to avoid produce
Raw bearing is injured the risk damaged, and to operator without relatively high-tech requirement, also reduces the potential safety hazard of human users simultaneously.
Summary of the invention
The main object of the present invention is for providing a kind of rolling bearing structure completing dismounting that can be simple and quick.
The present invention proposes a kind of rolling bearing structure, including bearing inner race, bearing outer ring assembly and be installed in described

Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1～6, proposing one embodiment of the invention, a kind of rolling bearing structure, including bearing inner race 2, bearing outer ring
Assembly and be installed in the rolling element 7 between bearing inner race 2 and bearing outer ring assembly, this rolling bearing structure will the bearing of motion
And the sliding friction between bearing block becomes rolling moly, and this bearing inner race 2 matches to merge with bearing and rotates together with bearing, should
Bearing outer ring assembly is wanted to coordinate with bearing block, plays a supporting role, and rolling element 7 is evenly distributed on outside this bearing inner race 2 and bearing
Between coil assembly, play the effect of rolling.
Bearing outer ring assembly includes that upper bearing (metal) outer ring 1 and lower bearing outer ring 3, upper bearing (metal) outer ring 1 lead to lower bearing outer ring 3
Cross threaded connector 4 to connect.
When bearing needs dismounting, first take out threaded connector 4, bearing outer ring assembly can be resolved into upper bearing (metal) outer ring
1 and lower bearing outer ring 3, now rolling element 7 can depart from between bearing outer ring assembly and bearing inner race 2.
Rolling bearing structure, is threaded connection 4 upper bearing (metal) outer rings 1 of part and is connected with lower bearing outer ring 3, is formed outside bearing
Coil assembly, it is ensured that the stability of connection, is readily disassembled in Renewal process in cleaning simultaneously, only need to take off threaded connector 4,
I.e. detachable, it is to avoid to produce bearing and injure the risk damaged, to operator without relatively high-tech requirement, also reduce personnel simultaneously
The potential safety hazard of operation, and it is possible to varying in size according to bearing, it is possible to use different threaded connectors 4 connects, and changes
Process has versatility, can be substantially reduced production cost.
Being provided with retainer 6 between bearing outer ring assembly and bearing inner race 2, above-mentioned rolling element 7 is embedded in retainer 6
In, when assembling, rolling element 7 loads in retainer 6, and this retainer 6 is fixed on the outer end of bearing inner race 2, makes rolling element 7 fix
After, it is connected to upper bearing (metal) outer ring 1 and lower bearing outer ring 3 with threaded connector 4 outer end of retainer 6, finally form rolling
Bearing；During dismounting, take out threaded connector 4 in the ban, bearing outer ring assembly can be resolved into upper bearing (metal) outer ring 1 and lower bearing
Outer ring 3, now rolling element 7 can be taken off from retainer 6, then is departed from from bearing inner race 2 by retainer 6.
Retainer 6 is provided with several circular ports arranged around the periphery of bearing inner race 2, and rolling element 7 embeds circle
In hole.
In the present embodiment, the bearing inner race 2 cylindrical shape in hollow is arranged, it can be by bearing metal, wear resistant cast iron, copper
Base and acieral, the material that roller bearing steel equal strength is high, wearability is good are made.The medial wall of this bearing inner race 2 is set in
On described bearing, and match to merge with this bearing and rotate together with this bearing.
It addition, described upper bearing (metal) outer ring 1 and lower bearing outer ring 3 cylindrical shape in hollow respectively is arranged, outside upper bearing (metal)
