When need bearing temporarily to pull down, after bearing damage, it is necessary to the bearing of damage is pulled down, the bearing for more renewing, therefore such as
What safe and effective dismounting end cap is particularly significant.
At present for non-divergence type bearing, it is possible to use special stripping attachment dismounting bearing, for example duplex pull rod stripping attachment or
Three pull bar stripping attachments, but both stripping attachments have that bearing housing gusset cannot be fixed, and also have in addition anti-using bolt
The mode of active force extruding dismounting, which has all directions bolt need to tighten successively, it is impossible to which, while operation, end cap stress is not
Equal problem, with bearing decentraction when easily making bearing housing out, end cap is crooked, causes bearing housing sealing surface and axle to damage,
To make all directions uniform force, it is necessary to improve the precision of instrument, cost is caused to increase.
Utility model content
The utility model devises a kind of device for quickly disassembling of bearing housing to solve the above problems, and change uses bolt
The mode of reaction force extruding dismounting, the outside tension uniform suffered by the utility model end cap will not be crooked, and can be good
The gusset of fixing bearing case, reaches the purpose safely, effectively removed.
To achieve these goals, the technological means that the utility model is taken is：
A kind of device for quickly disassembling of bearing housing, the device is used to dismantle the end cap of bearing housing, and key point is that described is fast
Dismantling device includes gate supporter, the lifting unit in the middle part of gate supporter and is fixed on the fixation of lifting unit lower end
Connection unit, lifting unit includes the pilot hole in the middle part of gate supporter, the threaded post in pilot hole and positioned at guiding
The thread bush of hole upper end, is fixedly connected unit to be provided with the circular fixed plate of spacing hole on end face, is provided with spacing hole and opened
Bolt is pulled out, is opened and is pulled out the nut lower surface of bolt and form position limiting structure with spacing hole upper surface, opened and pull out the shaft of bolt and pass through
Spacing hole and it is connected with the screwed hole on bearing box end cap.
Described opening pulls out the limiting stand that bolt is provided with circle below nut, and limiting stand pulls out bolt and is integrated knot with opening
Structure, is polished rod between limiting stand and nut, and the length of polished rod is not less than the thickness of circular fixed plate, described spacing hole cross section
It is Pear-Shaped, the diameter macropores in Pear-Shaped are more than the diameter of limiting stand, the diameter of the hole diameter less than limiting stand of Pear-Shaped
And more than the diameter of polished rod.
The lower end both sides of described gate supporter are respectively arranged with the draw-in groove of a side opening, two directions of draw-in groove opening
Conversely, the diameter of draw-in groove matches with the diameter of bolt of installation on bearing housing side wall structure bottom face.
The beneficial effects of the utility model are：The method for changing traditional utilization bolt reaction force extruding dismounting, uses
Open and pull out bolt end cap links together with unit is fixedly connected, gate supporter is propped up on the gusset bottom face of bearing housing, spiral shell
Line set is rotated down, and outwardly against threaded post, the end cap connected by being fixedly connected unit is outwards extracted together, and spacing hole is equal
Even distribution, stress point keeps balance in the center for being fixedly connected unit, end cap, and uniform force, will not produce abrasion everywhere.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is to open the structural representation for pulling out bolt.
In figure, 1, be fixedly connected unit, 2, gate supporter, 3, threaded post, 4, thread bush, 5, open and pull out bolt, 6, spacing
Hole, 7, limiting stand, 8, polished rod, 9, draw-in groove.
Specific embodiment
The utility model is a kind of quick-release arrangement of bearing housing, uses device and is fixedly connected on one with end cap
The mode outwards pulled out is played, stress will not produce unbalance stress to cause crooked problem in center.
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
Specific embodiment, as shown in figure 1, described device for quickly disassembling is including gate supporter 2, in gate supporter 2
The lifting unit in portion and be fixed on lifting unit lower end be fixedly connected unit 1, lifting unit includes the middle part of gate supporter 2
Pilot hole, the threaded post 3 in pilot hole and the thread bush 4 positioned at pilot hole upper end, be fixedly connected unit 1 for end face
On be provided with the circular fixed plate of spacing hole 6, be provided with to open in spacing hole 6 and pull out bolt 5, open pull out the nut lower surface of bolt 5 with
The upper surface of spacing hole 6 forms position limiting structure, open pull out the shaft of bolt 5 through spacing hole 6 and with bearing box end cap on spiral shell
Pit is connected.
As shown in Fig. 2 the limiting stand 7 that bolt 5 is provided with circle below nut is pulled out in described opening, limiting stand 7 is pulled out with opening
Bolt 5 is structure as a whole, and is polished rod 8 between limiting stand 7 and nut, and the length of polished rod 8 is not less than the thickness of circular fixed plate, institute
The cross section of spacing hole 6 stated is Pear-Shaped, and diameter of the diameter macropores more than limiting stand 7 in Pear-Shaped, the aperture of Pear-Shaped is straight
Footpath is less than the diameter of limiting stand 7 and more than the diameter of polished rod 8.
Open and pull out the limiting stand 7 of the lower end of bolt 5 and be partially placed into by the heavy caliber of Pear-Shaped spacing hole 6, nut is stuck in spacing hole 6
Outward, open pull out bolt 5 can enter spacing hole 6 in, be unlikely to fall into again to be difficult to control to fixed-direction in hole, by polished rod 8 along calabash
The structure of reed shape pushes osculum path portion by heavy caliber part, and the upper surface of limiting stand 7, bearing are blocked in the lower surface of spacing hole 6
Case is reserved with screwed hole, opens and pulls out bolt 5 and inwardly screw, and end cap is connected with unit 1 is fixedly connected, and so opens and pulls out bolt 5
It is not easy to the abjection from spacing hole 6.On the gusset bottom face of bearing housing, the upper end of threaded post 3 is provided with gate supporting construction 2
External screw thread, the internal thread of thread bush 4 is matched, and thread bush 4 is rotated down outwardly against threaded post 3, be fixedly connected unit 1 with
Threaded post 3 is linked, and end cap is outwards pulled out, and spacing hole 6 is uniformly distributed, and stress point is in center, and end cap uniform force is overall same
When outwards pull out, crooked will not produce abrasion, it is cost-effective to reduce required precision, and operation difficulty reduction is easy to use, and prolongs
The service life of long bearing case end cap.
The lower end both sides of described gate supporter 2 are respectively arranged with the draw-in groove 9 of a side opening, two openings of draw-in groove 9
In the opposite direction, the diameter of draw-in groove 9 matches with the diameter of bolt of installation on bearing housing side wall structure bottom face.The periphery of bearing housing
There is fixing bolt structure bottom, and the direction that draw-in groove 9 just blocks the opening of draw-in groove 9 on bolt, and two pillars is opposite, spiral shell
When line set 4 is rotated down, draw-in groove 9 prevents gate supporter 2 from occurring to turn with threaded post 3 from both direction clamping gate supporter 2
Dynamic or displacement, influence dismounting speed and quality.
