Concrete meaning in the present invention.
As shown in Figs. 1-2, it is a kind of sealing structure for gauge-changeable wheelsets provided in an embodiment of the present invention comprising outer
Ring 1, inner ring 2 and resilient sleeve 3, the internal diameter of the outer shroud 1 is more than the outer diameter of inner ring 2, outer shroud 1 is facilitated to be set in outside inner ring 2, described
One end of resilient sleeve 3 is fixedly connected with the inner circumferential of the outer shroud 1, and the other end of the resilient sleeve 3 and the periphery of the inner ring 2 are solid
Fixed connection forms telescopic integral structure, and the outer shroud 1 can drive the resilient sleeve 3 to be moved relative to the inner ring 2, specifically
Ground, the outer shroud 1 can be moved axially relative to the inner ring 2.Displacement distance between outer shroud 1 and inner ring 2 disclosure satisfy that
Relative movement distance when gauge changing between wheel 5 and axle 4, actual displacement distance become equal to the gauge-changeable wheelsets gauge
The half of change, to realize the sealing between wheel 5 and axle 4, and also it is simple and compact for structure, it is easy for installation.
Further, as shown in figure 3, variable rail gauge wheel is to including wheel 5 and axle 4, the wheel 5 slideably with institute
State the connection of axle 4, the internal diameter of the outer shroud 1 and the hub outside diameter of the wheel 5 match, the internal diameter of the inner ring 2 with it is described
The outer diameter of axle 4 matches, and the outer shroud 1 is for the fixed wheel hub for being set in the wheel 5, and the inner ring 2 is for fixing
It is set on the axle 4, saves sealing structure space to greatest extent, when gauge changing, outer shroud 1 is moved together with wheel 5, bullet
Property set 3 using its shape changeabilities and restorability, follow outer shroud 1 to move together, inner ring 2 is fixed, solves change
Wheel 5 and the sealing problem during 4 Relative sliding of axle, simple and compact for structure when gauge.
Specifically, the resilient sleeve 3 is preferably rubber cover, and the both ends of the rubber cover vulcanize respectively in the outer shroud
In 1 inner circumferential and the periphery of inner ring 2, the thickness of rubber cover can select according to actual needs, and sulfuration process is in rubber
The crosslinking coagents such as vulcanizing agent and accelerating agent are added makes linear macromolecule be changed into three dimensional network under certain temperature, pressure condition
The process of shape structure, the structure connection after vulcanization are very reliable.
In the embodiment of the present invention, the length of the outer shroud 1 is more than the length of the inner ring 2 so that outer shroud 1 can be complete
Inner ring 2 is coated, occupied space is minimum at this time, saves space.
Wherein, it is formed between the outer shroud 1, resilient sleeve 3, inner ring 2 and the wheel hub, axle 4 for encapsulating lubricating oil
Space encapsulates lubricating oil within this space, to keep the continuous lubrication between wheel 5 and axle 4, avoids inner ring 2, outer shroud 1
Between the sealing part abrasion that generates by relative movement, and good seal performance, No leakage.
It should be noted that the wheel 5 is connected with axle 4 by spline fitted, and specifically, the connecting hole of wheel 5
Equipped with internal spline, axle 4 is equipped with external splines, and wheel 5 is connected with axle 4 by internal spline and external splines, by torque
It is evenly distributed on 5 circumference of wheel, is both convenient for transmitting torque, wheel 5 is also allowed for and slides realization gauge changing along axle 4.
