Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Preferred embodiment:
This preferred embodiment discloses a kind of rolling bearing and tears unloading device open.As shown in Figures 2 to 5, which tears shutout open
The U-shaped fixed frame 1 for being used for fixed rotor main body 230 including one is set, is opened respectively in opposite two side walls on U-shaped fixed frame 1
Equipped with the rotation shaft opening 11 for wearing shaft 220；One, which is respectively arranged with, in every side of U-shaped fixed frame 1 moves back the support of bearing
2, it moves back the support of bearing 2 and is provided with carrier openings 21 for wearing shaft 220, U-shaped fixed frame 1 can move back the support of bearing 2 at two
Between move；The direction of line is identical between the force direction of power device 3 and rotation shaft opening 11 and carrier openings 21.
It is born against using U-shaped fixed frame 1 is fixed wait tear the sub rotor subject 230 of retreat open, move back the support of bearing 2 using two
Wait tear two rolling bearings 210 of retreat open, apply external force using power device 3 to enable the rolling bearing 210 wait tear retreat open
Separated with shaft 220, can tear open simultaneously every time move back wait tear open retreat son two rolling bearings 210, tear open move back it is high-efficient, without midway adjust
The whole disposing way wait tear retreat open；It moves back the support of bearing 2 and is entirely resisted against on rolling bearing 210 and (be precisely resisted against
On the side wall of the outer ring of rolling bearing 210), the force on rolling bearing 210 is average, guarantees to step back rolling bearing tearing open
210 inner ring is not damaged, and the integrality of rolling bearing 210 is high.
Tear the automation for moving back work open in order to improve, further increase to tear open and move back efficiency, rolling bearing tear open unloading device further include to
Few one automatic fixture 4 for carrying wait tear retreat open, automatic fixture 4 will be for that will be carried to U-shaped fixed frame wait tear retreat open
It 1 and is removed the rotor for moving back and finishing is torn open from U-shaped fixed frame 1.The specific structure of automatic fixture 4 is unlimited, can be and is pressed from both sides by two
The structure of pawl composition can be vacuum suction structure, can also be other structures, is able to achieve and carries wait tear the sub function of retreat open i.e.
It can.
The specific device of power device 3 is unlimited, can provide power to tear unloading device open.Preferably, power device 3 is gas
Cylinder or hydraulic pump, the power value exported are stablized, and product is mature, at low cost.
The mode that power device 3 exerts a force can be U-shaped fixed frame 1 and power device 3 is detachably connected, tears power when moving back open
Device 3 pushes the movement of U-shaped fixed frame 1, U-shaped fixed frame 1 with the movement of rotor subject 230, rotor subject 230 with shaft 220
It moves and moves back the support of bearing 2 at this time and be resisted against the inside of rolling bearing 210 (close to rotor subject 230 on rolling bearing 210
Side) to prevent rolling bearing 210 mobile with shaft 220, then rolling bearing 210 is separated with 220 phase of shaft.
The mode that power device 3 exerts a force can also be that power device 3 is connected to and move back the support of bearing 2, tear U-shaped fixed frame when moving back open
1, rotor subject 230 and shaft 220 all remain stationary, and the drive of power device 3 moves back the support of bearing 2 outward (on rolling bearing 210
Side far from rotor subject 230) direction it is mobile, enable rolling bearing 210 be detached from from shaft 220.
On the basis of above structure, it is obliquely provided with sliding rail 5 in the outside for moving back the support of bearing 2, the end of sliding rail 5 connects
It is connected to rolling bearing collection box.The rolling bearing 210 separated from shaft 220 enters rolling bearing along sliding rail 5 and receives
Collect box, reduces the workload artificially collected.
On the basis of above structure, it further includes at least one set of for placing wait tear retreat open that rolling bearing, which tears unloading device open,
Shelf 6, every group of shelf 6 include two pieces of shelf plates disposed in parallel；The upper surface of shelf 6 is oblique, close to U-shaped fixed frame 1
End be lower than the end far from U-shaped fixed frame 1, guarantee can be rolled to automatically wait tear retreat open close to U-shaped fixed frame on shelf 6
1, close to the place of automatic fixture 4, the moving distance of automatic fixture 4 is reduced, improves working efficiency.
It can apply to various model rotors 200 and tear open move back work to guarantee that the rolling bearing tears unloading device open, every group of shelf 6
Distance is adjustable between two pieces of shelf plates, two pieces of shelf plates of every group of shelf 6 when the rotor subject 230 wait tear retreat open is larger
The distance between width, when wait tear open retreat son rotor subject 230 it is smaller when every group of shelf 6 the distance between two pieces of shelf plates
It is narrow；Correspondingly, the distance between two side walls opposite on U-shaped fixed frame 1 are also adjustable, as the rotor master wait tear retreat open
The distance between two side walls opposite on U-shaped fixed frame 1 width when body 230 is larger, when wait tear open retreat son rotor subject 230 compared with
The distance between opposite two side walls are narrow on hour U-shaped fixed frame 1.
In order to guarantee power device 3 force direction can always between rotation shaft opening 11 and carrier openings 21 line side
To it is identical, avoid tear open move back during power device 3 force direction change, it further includes leading that rolling bearing, which tears unloading device open,
Rail, U-shaped fixed frame 1 and/or moves back the support of bearing 2 and is fastened on guide rail and can move along guide rail.Specifically U-shaped fixed frame 1 and/
Or which of move back the support of bearing 2 and be interlocked with guide rail or be both interlocked with guide rail can be according to power device 3
Force mechanism determines.
In order to avoid because the inner ring and outer ring diameter of the rolling bearing 210 of some models quite due to cause to tear open move back during in
Circle is pressurized, and the width for moving back the carrier openings 21 on the support of bearing 2 is straight greater than the inner ring of the rolling bearing 210 wait tear retreat open
Diameter and the diameter for being less than the outer ring wait tear the sub rolling bearing 210 of retreat open, tear open and move back the only extrusion rolling of the support of bearing 2 during moving back
The integrality for stepping back rotor is torn in the outer ring of bearing 210, guarantee open.
Note that the technical principle that above are only presently preferred embodiments of the present invention and used.Those skilled in the art can manage
Solution, the invention is not limited to the specific embodiments described herein, is able to carry out various apparent changes for a person skilled in the art
Change, readjust and substitutes without departing from protection scope of the present invention.Therefore, although by above embodiments to the present invention into
It has gone and has been described in further detail, but the present invention is not limited to the above embodiments only, without departing from the inventive concept,
It can also include more other equivalent embodiments, and the scope of the invention is determined by the scope of the appended claims.
