Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and specifically
This utility model is described in detail by embodiment.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
A kind of railway locomotive derailing device as shown in Figure 1 and Figure 2 seals structure, mainly includes derailing wheel 2, supports
Axle 3, bearing 8 and joint gland 10 and exterior seal ring 12, wherein, with mistake between one end and bearing 8 endoporus of described support shaft 3
The fit system that is full of is fixing to be connected, and the other end is bolted to connection with installing rack 5；Described derailing wheel 2 is sleeved on bearing 8
Periphery；Described joint gland 10 is fixedly connected on outside derailing wheel 2 by connecting bolt 11 and covers outside bearing 8
Side；Described exterior seal ring 12 is fixedly connected on inside derailing wheel 2 by connecting bolt 11 and covers inside bearing 8, thus
Make to constitute relatively turnable flexible connection by bearing 8 between derailing wheel 2 and support shaft 3, and, by joint gland
10, exterior seal ring 12 and derailing wheel 2 cladding bearing 8 jointly, define the sealing structure of anti-derail unit.
As it is shown in figure 1, when railway locomotive wheel 7 along rail 4 properly functioning time, its both sides derailing wheel 2 equal positions
Below sleeper beam 1 and and sleeper beam 1 between keep suitable gap.Generally, between described derailing wheel 2 and sleeper beam 1 lower plane
Gap design gives in accordance with the following methods: by the dynamics calculation of locomotive, it is considered to locomotive is under applicable line condition, not
When passing through at different rates in same sweep, the maximum vertical deviation of anti-derail unit is a, and considers that sleeper beam is put down for 1 time
Face is b with the foozle of rail 4 end face spacing, then the gap between derailing wheel 2 and sleeper beam 1 lower plane is designed as: a+b
+ (1～2mm).Owing to the anti-derail unit of railway locomotive both sides is all exposed in natural environment, therefore, pass through anti-derail unit
Sealing structure can effectively to stop the foreign material such as the dust storm in external elements, rainwater to enter into bearing 8 internal, thus protect
Demonstrate,prove the normal work and use life-span of bearing 8.
As in figure 2 it is shown, increase the axial compression lid 9 arranging T-shaped hierarchic structure outside support shaft 3, described axial compression lid 9 and support
Connected fixing between axle 3 by connecting bolt 11, the lobe on described axial compression lid 9 extend in bearing 8 endoporus, axial compression lid 9
Circumferential ends then seal compression bearing 8 inner ring, therefore, between described axial compression lid 9, bearing 8, support shaft 3, also constitute one
Individual sealing structure, to prevent the foreign material such as dust storm, rainwater from entering in the cavity between support shaft 3 and bearing 8.
In order to improve exterior seal ring 12 to bearing 8, the sealing property of support shaft 3, as in figure 2 it is shown, can be at bearing 8 with outer
Inner seal ring 13 is set between sealing ring 12, solid with interference fit between endoporus and the support shaft 3 of described inner seal ring 13
Fixed connection.Can also arrange the shaft shoulder 31 in support shaft 3, described inner seal ring 13 is fixedly mounted between the shaft shoulder 31 and bearing 8,
Inner seal ring 13 can be limited by the shaft shoulder 31 to move right relative to exterior seal ring 12, not only compact conformation, so that
Suitable gap is kept, to ensure to relatively rotate between derailing wheel 2 and support shaft 3 between exterior seal ring 12 and inner seal ring 13
Smoothness.The sealing property reliability of structure is sealed in order to improve anti-derail unit further, as in figure 2 it is shown, including can
Be respectively provided with rectangle double wedge, rectangular recess on sealing ring 13, exterior seal ring 12, and the rectangle double wedge being positioned on inner seal ring 13 with
The rectangular recess being positioned on exterior seal ring 12 engages each other, the rectangular recess being positioned on inner seal ring 13 be positioned at exterior seal ring 12
On rectangle double wedge engage each other, this sealing structure not only seals reliably, and handling ease, advantageously reduces inner seal ring
13, the production cost of exterior seal ring 12.Double wedge, groove on described inner seal ring 13, exterior seal ring 12 can also be wedges respectively
Shape double wedge, wedge-shaped impression, this wedge structure has certain guide effect, makes between inner seal ring 13, exterior seal ring 12
Relatively rotate more smooth and easy and seal reliable, it addition, this wedge structure can also make to enter in double wedge, engagement space
Pollute impurity to accelerate to flow out anti-derail unit sealing structure, thus the pollution impurity entered in double wedge, engagement space is risen
Arrive certain automatic cleaning effect, advantageously ensure that the normal work of bearing 8.
Above-mentioned railway locomotive derailing device seals structure and following steps can be used to realize:
First, inner seal ring 13 is installed；Described inner seal ring 13 uses between press-fit approach and support shaft 3 with interference fit
Mode is fixing to be connected, and makes the inner seal ring 13 shaft shoulder 31 in support shaft 3.
Then, bearing 8 is fixedly installed in support shaft 3 with interference fit；Described bearing 8 inner ring uses hot charging side
Formula is installed to the correct position in support shaft 3, preferably against inner seal ring 13.Before hot charging, the inner ring of bearing 8 is first used
Oil bath or Electromagnetic Heating are to 90-100 DEG C, then are installed in support shaft 3 specify position, and compress inner seal ring 13.
Secondly, axial compression lid 9 is installed；Use connecting bolt 11 fixing by being connected between axial compression lid 9 with support shaft 3, and make axle
Gland 9 circumferential ends seals, compresses outside bearing 8 inner ring.By inner seal ring 13 against the shaft shoulder 31, axial compression lid 9 and support shaft 3
Connect fixing, jointly limit moving axially of bearing 8 inner ring, to ensure the reliability of railway locomotive derailing device.
It follows that derailing wheel 2 set is installed to outside bearing 8.Described derailing is taken turns between 2 and bearing 8 outer ring best
It is set with gap fiting mode, the most easy for installation, it is often more important that, in railway locomotive running, if because of partially
Corner is excessive and causes between derailing wheel 2 and sleeper beam 1 lower plane when producing mutual squeezing action power, due to derailing wheel 2 with
Bearing 8 is matched in clearance between outer ring, therefore so that derailing wheel 2, bearing 8 all can obtain a certain degree of buffering, thus
Derailing wheel 2, bearing 8 are played certain protective effect；It addition, when railway locomotive is properly functioning, or deflection angle is less
Time, mutual squeezing action power will not be produced between derailing wheel 2 and sleeper beam 1 lower plane, therefore, derailing wheel 2 is relative to sleeper beam
1, derailing wheel 2 all will not relatively rotate relative to support shaft 3 relative to bearing 8, derailing wheel 2, thus alleviate anti-
It is energy-saving and cost-reducing that derailing wheel 2, the frictional dissipation of bearing 8, beneficially railway locomotive run.
Finally, joint gland 10 and exterior seal ring 12 are installed；Described joint gland 10 is fixed by connecting bolt 11
It is connected on the left of derailing wheel 2, described exterior seal ring 12 is fixedly connected on the right side of derailing wheel 2 by connecting bolt 11,
Described joint gland 10, exterior seal ring 12, derailing wheel 2 cladding bearings 8 jointly, as shown in Figure 2.So far, preventing railway locomotive
The sealing structure of derailing device completes.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, it should refer to
Go out, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should comprise
Within protection domain of the present utility model.
