Description
Technical field
The utility model belongs to electrical machmary maintenance technical field, and more particularly to a kind of outside motor part dismounting is protected with bearing and filled
Put.
Background technology
At present, the external component of plant equipment is typically dismantled in dismounting using hydraulic jaw, newel and the electricity of hydraulic jaw
Machine rotating shaft is mutually leaned to one reverse active force of cleft hand of hydraulic jaw, and cleft hand leans on this reaction force by outside motor portion
Part removes；When newel interacts with machine shaft, front end bearing inner race is transmitted the force to first after rotating shaft stress, then
Front end bearing outer ring is transferred force to by ball, last front end bearing outer ring transfers force to end cap seam.In power transmission
During, ball can leave impression in raceway, and this will cause to damage and influence rolling of the ball in raceway on raceway, right
For big motor, bearing is expensive, wastes time and energy during replacing.
The content of the invention
The purpose of the utility model is that outside motor part is torn open using hydraulic jaw in the prior art for solution is above-mentioned
When unloading, the problem of ball leaves impression in raceway and must change bearing, and propose a kind of outside motor part dismounting axle
Accept insurance protection unit, adopted the technical scheme that to reach above-mentioned purpose：
A kind of outside motor part dismounting bearing protection device, including female sleeve pipe is set, in one end one of sleeve pipe
Body is provided with the stationary annular side extended to outer circumferential, and circumferentially direction is uniformly provided with multiple mounting holes in annular edge, is covering
Threaded post is equipped with pipe, the external screw thread being engaged with internal thread is provided with the outer circumference surface of threaded post, in the tail of threaded post
End is provided with rotating disk, and ladder counterbore is provided with the front end of threaded post.
Preferably, the ladder counterbore is multistage ladder counterbore, and the diameter of every grade of counterbore corresponds to a kind of type motor rotating shaft
Diameter.
Preferably, the internal diameter of described sleeve pipe is not less than the external diameter of rotating shaft bearing of motor.
Had the beneficial effect that possessed by the utility model：, can be quickly by this when being dismantled to outside motor part
Device is arranged on drive end bearing bracket to be played a protective role to fore bearing, solves ball and raceway is caused to damage and must change axle
The problem of holding；Because threaded post can be with precession or back-out to change the distance between ladder counterbore and machine shaft, so as to not
Machine shaft with extension elongation can use；Another aspect ladder counterbore even meets making for different machine shaft diameters
With.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of outside motor part dismounting bearing protection device, including set female sleeve pipe
3, the stationary annular side 4 extended to outer circumferential is integrally formed with one end of sleeve pipe 3, circumferentially direction is uniform in annular edge 4
Provided with multiple mounting holes 5, threaded post 2 is equipped with sleeve pipe 3, is provided with the outer circumference surface of threaded post 2 and matches with internal thread
The external screw thread of conjunction, rotating disk 1 is provided with the tail end of threaded post 2, is provided with ladder counterbore 6 in the front end of threaded post 2, the ladder sinks
Hole 6 is multistage ladder counterbore, and the diameter of every grade of counterbore corresponds to a kind of diameter of type motor rotating shaft, and the internal diameter of described sleeve pipe 3 is not
Less than the external diameter of rotating shaft bearing of motor 9.
As shown in Fig. 2 rear bearing 13 is fixed with the rear end cap 11 of motor body, it is fixed in the drive end bearing bracket 8 of motor body
There is fore bearing 9, fore bearing 9 and rear bearing 13 are coaxially disposed, and machine shaft 10 is equipped with fore bearing 9 and rear bearing 13,
The rear end of machine shaft 10 is fixed with external component, such as blade fan 12, and blade fan 12 is located at the rear side of rear bearing 13, after general
The gap surplus for being used for expanding with heat and contract with cold is provided between the outer ring of bearing 13 and rear end cap 11.
This protection device when in use, is coaxially mounted on drive end bearing bracket 8, then by the utility model by bolt 7 first
Rotating disk 1 is rotated, threaded post 2 is close to machine shaft 10, stops until machine shaft 10 is held out against in corresponding ladder counterbore 6
Spin-ended to rotate rotating disk 1, the newel of most relief hydraulic jaw is acted against on the end face of the machine shaft 10 of the rear side of blade fan 12, hydraulic pressure
The cleft hand of pawl blocks blade fan 12, so as to which blade fan 12 be disassembled.Due to the front end face and ladder counterbore 6 of machine shaft 10
Mutually hold out against, so the power when the center capital of hydraulic jaw and machine shaft 10 interact is acted directly in threaded post 2
And be delivered on drive end bearing bracket 8, such fore bearing 9 serves protective effect without endurance to it.On the other hand, due to rear bearing 13
Outer ring and rear end cap 11 between be provided with and be used for the gap surplus expanded with heat and contract with cold, when dismantling blade fan 12, fore bearing 9 be first by
Power, therefore fore bearing 9 need to only be protected.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent change and modification that the technical essence of the utility model is made to above example, belongs to this reality
With the protection domain of new technique scheme.
