Abstract
A kind of EMU axle-mounted brake disk drag ring disassembly mechanism, it is characterised in that：Including supporting item, compressing member and clamp nut, the connecting rod on supporting item belongs to half-thread bar, and compressing member is a bending plate, and the threaded hole of half-thread bar through compressing member is locked by clamp nut.The disassembly mechanism of the present invention is light, simple, easy to operate, while after multiple spot is symmetrically installed, and when extruding ensures by separation member uniform force, not damaged.Because brake disc belongs to component of the mounting hole with circle symmetrical structure, drag ring, hub quick separating can be realized using the structure, and ensure that brake disc connecting portion not damaged, the flaw detection of brake disc is finally realized, has saved repair and maintenance cost.
Description
Technical field
The present invention relates to rail vehicle parts disassembly mechanism, more particularly, to a kind of axle-mounted brake disk drag ring demountor
Structure.
Background technology
During overhaul of train-set, need if necessary to axle-mounted brake disk hub connecting flange root（Drag ring connects with hub
At conjunction）Carrying out flaw detection is carried out, checks for crackle.Need to separate brake disc drag ring with wheel hub before inspection.In reality
In operating process, occur because contact surface corrosion, drag ring fitted position are because high temperature deformation leads to not separate, if without reasonably tearing open
Mode is unloaded, brake disc will scrap to cause significant wastage.
The content of the invention
The object of the present invention is to provide one kind to contribute to brake disc drag ring disassembly mechanism separated with wheel hub, realizes hub
Connecting flange root（Drag ring and hub joint）Carrying out flaw detection.Solve the problems, such as that drag ring and hub can not be separated, from
And ensure that the normal flaw detection work of hub, save cost of overhaul use.
To achieve the above object, the present invention provides a kind of EMU axle-mounted brake disk drag ring disassembly mechanism, its feature exists
In：Including supporting item, compressing member and clamp nut, the connecting rod on supporting item belongs to half-thread bar, and compressing member is a bending plate,
The threaded hole of half-thread bar through compressing member is locked by clamp nut.
The supporting item half-thread bar is located at compressing member upper surface and the centre of supporting item lower surface distance.
The disassembly mechanism of the present invention is light, simple, easy to operate, while after multiple spot is symmetrically installed, and when extruding ensures to be separated
Part uniform force, not damaged.Because brake disc belongs to component of the mounting hole with circle symmetrical structure, it can be realized and rubbed using the structure
Ring, hub quick separating are wiped, and ensure that brake disc connecting portion not damaged, the flaw detection of brake disc is finally realized, has saved inspection
Repair maintenance cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is working state figure of the present invention.
Embodiment
With reference to Fig. 1, the present invention includes supporting item 1, compressing member 2 and clamp nut 3, and the connecting rod on supporting item 1 belongs to partly
Threaded rod, compressing member are a bending plate, and the threaded hole of half-thread bar through compressing member 2 is locked by clamp nut 3, the branch
Support member half-thread bar is located at compressing member upper surface and the centre of supporting item lower surface distance, drag ring 5, hub 4 is easier to point
From.
With reference to Fig. 2, which, which is suitable for mounting hole, has the component of circle symmetrical structure, when mechanism is installed, supporting item
Stationary plane be located at inner side, compressed with 4 surface of hub, compressing member stationary plane holds out against with drag ring 5, supporting item 1 and by separation unit
The direction of motion of part hub 4 is consistent, and compressing member 2 is consistent with 5 direction of motion of drag ring, while is symmetrically pacified using multiple disassembly mechanisms
Dress, rotational fastener nut promotes compressing member successively in order, realizes that drag ring 5, hub 4 quickly divide eventually through interaction force
From.
