Description
Technical field
It the utility model is related to disassembling fixture technical field, more particularly to a kind of provision for disengagement of swelled shaft coupling.
Background technology
Motor in type approval test before dispatching from the factory, all needs to use the special shaft coupling with swelled, swelled shaft coupling every time
Device generally comprises expansion sleeve and shaft coupling, and is exited again by this shaft coupling is lossless after off-test.And it is current, dismantle tensioner
Formula shaft coupling mainly draws horse to be dismantled using hydraulic screw extractor.In general, hydraulic screw extractor is in use, it is necessary to coordinate fire
Flame heats or the mode of Medium frequency induction auxiliary heating pulls out shaft coupling.Operating process is generally：By the tension bolt on shaft coupling
Unscrew and allow expansion sleeve releasing pressure automatically, three pawl hooks of hydraulic screw extractor are then lived into the end face of shaft coupling, hydraulic pump withstands rotating shaft end
Face, shaft coupling is extracted by the pulling force of hydraulic pump.
But there is also following drawback for hydraulic screw extractor：Its load force to pulled object has certain requirement, needs during use
The hydraulic screw extractor of corresponding tonnage is selected, when pulled object exceedes nominal load, the meeting automatic deloading of overloading valve, then needs to reelect with more
The hydraulic screw extractor of large-tonnage.Hydraulic screw extractor never overloads use, does not otherwise finish dismounting task not only, it is also possible to which damage is by drawing thing
Body or product.Found in actual production, i.e., using 200T hydraulic pressure draw agate also can not every time smoothly by the lossless pull-out of this shaft coupling,
Sometimes it also may require that carrying out heating to tapered sleeve with medium frequency induction heater could pull out, but the time expended every time is all longer, such as
If encountering the tighter situation of tapered sleeve match ratio, even if shaft coupling still can not be pulled out with Frequency Induction Heating.Drawn when using hydraulic pressure
When horse traction shaft coupling exceedes rated oil pressure power, danger coefficient rapidly increases, and the possibility for damaging shaft coupling and motor shaft increases
Greatly, therefore often there is the difficult pull-out of tensioner type shaft coupling or can not pull situation about coming.
In addition, with stress when because the span of claw is too big, causing drawing during 3 claw hydraulic screw extractor drawing shaft coupling not
Equilibrium, because tensioner type shaft coupling load force is big, and tensioner tapered sleeve match ratio is tighter, and common three pulling force for grabbing drawing horse can not reach
To the requirement for pulling out tensioner type shaft coupling.Even if now drawn by the way of flame heating or Medium frequency induction auxiliary heating with hydraulic pressure
Horse can not also extract shaft coupling.
In summary, how to solve swelled dismounting coupling complex operation, and the peace for pulling rotating shaft and shaft coupling be present
The problem of full hidden danger, it has also become those skilled in the art's technical barrier urgently to be resolved hurrily.
