The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
As Fig. 1, 2, shown in 3, this binding ring stationary track vehicle elastic wheel, comprise rim 1, earth lead 2, the interior core wheel 3 that arranges of described rim 1, between described rim 1 and core wheel 3, by elastic damping material ring 4, separate, earth lead 2 one end are connected with rim 1, the other end is connected with core wheel 3, described core wheel 3 comprises inner ring 31 and outer thimble 32, in the outer conical surface of described inner ring 31, along circumferential direction, be provided with annular slot 5, in described annular slot 5, be provided with binding ring 6, described annular slot 5 is positioned at the outer lower portion of the outside of outer thimble 32 and the inside upper part of binding ring 6 and outer thimble 32 and is close to, on the end face in described inner ring 31 outsides, be provided with a plurality of grooves 8, described groove 8 runs through annular slot 5 along axial direction setting and the groove 8 of inner ring 31.The working process of this binding ring stationary track vehicle elastic wheel is as follows: during installation, elastic damping material ring 4 is positioned over to the matched position with rim 1, the outer circumference surface and the rim 1 inner peripheral surface pairing that are elastic damping material ring 4 are affixed, then inner ring 31 is positioned over to the position of mating with elastic damping material ring 4, be that the outer conical surface of inner ring 31 and the inner peripheral surface of elastic damping material ring 4 mate and be affixed, and rim 1, inner ring 31 medial surfaces are close in conplane dismantling devices back shield; Then, outer thimble 32 is positioned over and elastic damping material ring 4 matched positions, the internal conical surface of outer thimble 32 mates and is affixed with the outer circumference surface of elastic damping material ring 4; And then dismantling devices thimble 32 outside pushing vertically under the combined action of rear plate washer, makes elastic damping material ring 4 distortion that is squeezed, until expose annular slot 5; And then strut binding ring 6, put it in the annular slot 5 on inner ring 31 and be close to cell wall; Again, unclamp dismantling devices and vertically pushing outer thimble 32 thrust pressure, outer thimble 32 is close to binding ring 6 under the expansive force of elastic damping material ring 4; Finally, the earth lead 2 that connects rim 1 and inner ring 31 is installed, is installed; During work, wheel-rail contact force is close to extruding elastic damping material ring 4 by rim 1 inner peripheral surface; Recessed " V " font outer peripheral face that inner ring 31 and outer thimble 32 form also correspondence is close to extruding elastic damping material ring 4; Between rim 1 and inner ring 31 and outer thimble 32, never directly touch; Whole Wheel Rail Contact impact load and energy all intactly transmit by elastic damping material ring 4, can fully ensure performance effect of vibration and noise reduction, and Just because of this, elastic wheel must have earth lead 2; During dismounting, order is contrary with installation, first pulls down the earth lead 2 that connects rim 1 and core wheel 3; Dismantling devices pushes outer thimble 32 vertically, makes elastic damping material ring 4 distortion that is squeezed, until outer thimble 32 disengages with binding ring 6; Then binding ring 6 is strutted from annular slot 5 and take out; Unclamp dismantling devices, can take off successively outer thimble 32, inner ring 31 and elastic damping material ring 4, complete dismounting.By encircling at heart on the end face in 31 outsides, a plurality of grooves 8 are set, described groove 8 runs through annular slot 5 along axial direction setting and the groove 8 of inner ring 31, when installation or removal binding ring, force application means can be stretched into groove 8 and apply application force from the inner peripheral surface of binding ring 6, can very easily binding ring 6 be strutted, thereby very easily by binding ring 6 from the interior taking-up of annular slot 5 or be arranged in annular slot 5, and then make the dismounting of whole elastic wheel and easier for installation quick.
The stress transmitting in order effectively to reduce locking contact, extending structure service life, the cross sectional shape of described annular slot 5 is semicircle, the lower section of described binding ring 6 is shaped as semicircle and matches with the cross sectional shape of annular slot 5, the inside upper part surface of described binding ring 6 is arc surface or inclined-plane, the outer lower portion surface laminating of described arc surface or inclined-plane and outer thimble 32, as shown in Figure 1.The preferred mode of another one is: the cross sectional shape of described annular slot 5 is rectangle, described binding ring 6 lower section are shaped as rectangle and match with the cross sectional shape of annular slot 5, the inside upper part surface of described binding ring 6 is arc surface or inclined-plane, the outer lower portion surface laminating of described arc surface or inclined-plane and outer thimble 32, as shown in Figure 2, annular slot 5 and the binding ring 6 of this cross sectional shape, can make binding ring 6 and outer thimble 32, the area of contact of annular slot 5 is maximum, thereby reduce the stress of the transmission of unit area, extend binding ring 6, the service life of annular slot 5.
For the ease of earth lead 2 is installed; simultaneously for protective grounding wire 2 is not damaged in wheel operational process yet; described earth lead 2 one end are connected with rim 1; the other end is connected with core wheel 3 through groove 8; make like this earth lead 2 be positioned at groove 8, utilize 8 pairs of earth leads of groove 2 to form protection.
Elasticity sound-absorbing, absorbing material that described elastic damping material ring 4 can adopt various mechanical and physical performances to meet service demand are made, in order to guarantee elastic damping material ring 4, correctly install, location positioning is convenient and swift, described elastic damping material ring 4 is domain structure, can avoid piece formula elastic damping material ring tram to coordinate the problem of difficulty being installed and may causing the inharmonious work of ring in uncertain working load effect.
In the operational process of elastic wheel, for fear of dust, enter elastic wheel inside, simultaneously also in order to make whole wheel profile attractive in appearance, the front web face of described inner ring 31 is fixed with the dust retaining ring 7 of wheel.
In addition, the rough part of all structures of described elastic wheel all adopts arc transition, does not have stress concentration effect and significantly reduction of application stress, lightweight construction, and the life-span is long.
