Description
Technical field
The utility model is related to a kind of split-type shaft nested structures of mechanical stirrer intermediate bearing, belong to PTA device techniques neck
Domain.
Background technology
In the prior art, the axle sleeve that PTA devices first crystallize mechanical stirrer intermediate bearing is monoblock type axle sleeve, and axle sleeve is in work
It is easy to wear during work, it needs to regularly replace, when being replaced to existing monoblock type axle sleeve, need to first dismantle blade, blade disassembly process
In its fixed jackscrew be easily broken off, increase dismounting difficulty；The workload for replacing axle sleeve every time is larger, and additional increase stirs
The maintenance cost of machine.
Utility model content
To solve defect of the existing technology, the purpose of this utility model is to provide a kind of without dismantling blade, improving
Axle sleeve replaces the split-type shaft nested structure of the crystallization mechanical stirrer intermediate bearing of PTA devices first of efficiency.
The technical solution of the utility model is：A kind of PTA devices first crystallize the split-type shaft of mechanical stirrer intermediate bearing
Nested structure, including it is detachably arranged in the dissection type axle sleeve of agitating shaft periphery, the dissection type axle sleeve is locked by holding card, is cutd open
Fraction axle sleeve periphery is equipped with bearing block, and bearing shell is equipped between the bearing block and dissection type axle sleeve, and bearing block connects support plate, institute
It states support plate and is fixed on agitator tank center.
Support plate is bolted in the bearing block.
The support plate schedules agitator tank center by several pull rods.
The agitating shaft end connects stirrer paddle.
The holding card quantity is two, is respectively arranged at the upper and lower ends of dissection type axle sleeve.
The holding card is locked by lock screw.
The dissection type axle sleeve is detachable and symmetric design two parts.
PTA devices first crystallize the assembly and disassembly methods of the split-type shaft nested structure of mechanical stirrer intermediate bearing, and specific steps are such as
Under：
S1) turn bolt removes bearing block；
S2) the lock screw in turn holding card makes holding card be unclamped from split-type shaft set, removes holding card；
S3 after) losing the coupling mechanism force of holding card, two parts of dissection type axle sleeve separate automatically, by described two parts from stirring
It is removed on axis；
S4) two parts of new dissection type axle sleeve are fastened on agitating shaft periphery；
S5) in the upper holding card of split-type shaft set upper and lower ends set, and lock screw is tightened；
S6 bearing block) is installed on dissection type axle sleeve periphery, bearing block is mounted on by bolt in support plate.
The utility model has the beneficial effects that：I.e. detachable dissection type after only needing intermediate bearing to remove in maintenance process
Axle sleeve has saved maintenance time；The step of dismounting blade is eliminated in maintenance process, difficulty is very in disassembly process for blade
Greatly, and in tank lifting is relatively difficult, has saved the labour cost for removing blade.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Reference numeral is as follows in figure：1, agitating shaft, 2, dissection type axle sleeve, 3, holding card, 4, bearing block, 5, bearing shell, 6, support
Disk, 7, pull rod, 8, bolt.
Specific implementation mode
1 pair of the utility model is described further below in conjunction with the accompanying drawings：
A kind of split-type shaft nested structure of the crystallization of PTA devices first mechanical stirrer intermediate bearing, including be removably arranged
Dissection type axle sleeve 2 in 1 periphery of agitating shaft, the dissection type axle sleeve 2 are locked by holding card 3, and 2 periphery of dissection type axle sleeve is equipped with axis
Bearing 4 is equipped with bearing shell 5 between the bearing block 4 and dissection type axle sleeve 2, bearing block 4 connects support plate 6, and the support plate 6 is solid
Due to agitator tank center.
The bearing block 4 connects support plate 6 by bolt 8.
The support plate 6 is fixed on agitator tank center by several pull rods 7.
1 end of the agitating shaft connects stirrer paddle.
3 quantity of the holding card is two, is respectively arranged at the upper and lower ends of dissection type axle sleeve 2.
The holding card 3 is locked by lock screw.
The dissection type axle sleeve 2 is detachable and symmetric design two parts.
Dissection type axle sleeve removes and installs process：Bearing block 4 only need to be removed, then removes axle sleeve holding card 3, holding card 3 is removed
Two parts of rear axle housing separate, and axle sleeve also just removes, and measure the new axle sleeve of i.e. replaceable installation after shaft size, when installation,
First the two parts for the dissection type axle sleeve 2 chosen are fastened on 1 periphery of agitating shaft, then cover upper holding card 3 in axle sleeve upper and lower ends,
Holding card 3 is locked by lock screw, and then axle sleeve is held tightly and is saved without vibration, opposite monoblock type dismounting on agitating shaft 1
The step of having removed dismounting blade.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into modification.
