Abstract
The utility model relates to a shaft box of a duct piece vehicle. The structure characteristics of the shaft box of the duct piece vehicle are that a sleeve end takes the shape of a bell mouth; afterimprovement, a shaft shoulder of the sleeve is removed and a chamfer is increased; an end cover is improved to be sealed by double slots from original single slot; one sealing slot is provided with adustproof ring for sealing; and the other sealing slot can store lithium base grease which can effectively lubricate the end cover, a vehicle shaft, a bearing, and the like, and reduce the wear amongeach assembly piece. The improvement of the sleeve and the end cover, as well as the adoption of the dustproof ring for sealing the end cover and the sleeve, leads the water seepage problem of the shaft box of the duct piece vehicle to be essentially solved. Secondly, the improvement is conducive to the assembly of the sleeve and the vehicle shaft, as well as the assembly of the sleeve and the dustproof ring, and the like.
Description
Technical field
The utility model relates to a kind of section of jurisdiction axle box.
Background technology
The industrial and mineral car is applicable to the transportation traction in non-explosion-proof places such as industry narrow gage railway ground such as coal, metallurgy, mine, forest, railway, highway tunnel construction.In subway shield tunnel construction, join slave part after the composition shield drivings such as industrial and mineral car, mortar car, dregs car, section of jurisdiction car, be the essential condition of shield machine normal operation.The section of jurisdiction car is to transport the designed vehicle in section of jurisdiction in the subway shield tunnel construction specially, and it also undertakes the task of transporting material simultaneously.Wherein, the axle box composition is one of critical component of section of jurisdiction car.Along with the automation of subway work job facilities, the increasing of customizations degree, the section of jurisdiction car more and more is used in the subway work scene, but because the topographic condition of camp site is abominable, muddy water, mortar often flood positions such as section of jurisdiction car traveling portion axle box, cause the section of jurisdiction axle box water inlet problem to occur, and become a great problem that influences section of jurisdiction car life-span and construction safety and progress.Section of jurisdiction axle box water inlet can cause axle box normally to lubricate, and causes damage parts such as axletree, bearing in the axle box, greatly reduces the service life of axle box, also can bring consequences such as contaminated environment.
Summary of the invention
At the problem of section of jurisdiction axle box water inlet, the purpose of this utility model just provides the axle box of a kind of section of jurisdiction car.It is to improve by the design to cover and end cap in the former axle box composition, removes the former axle box felt sealing of section of jurisdiction car, uses the dust ring sealing instead, has solved section of jurisdiction axle box water inlet problem.
The purpose of this utility model is to realize by following measure:
A kind of section of jurisdiction axle box is made of cover, dust ring, end cap, abrasion plate, adjusting pad, bearing, spindle nose back-up ring, locking iron wire, packing ring, screw, rear side housing and journal box body.Cover is an interference fit with axletree, and the cover end is loudspeaker mouthful shape.End cap is inserted in the cover, and end cap is the double flute sealing, and a road sealing groove is equipped with dust ring.Between end cap and spindle nose back-up ring bearing is housed, locking iron wire, packing ring, screw are housed on the spindle nose back-up ring; Spindle nose back-up ring bottom is provided with rear side housing, and journal box body embeds between end cap and rear side housing, and with screw that rear side housing and adjusting pad and journal box body is fastening, the journal box body side has the abrasion plate.
The beneficial effect of advantage of the present utility model and generation is:
1, during axle box is formed, changes the sealing of ￠ 125 (JB/ZQ4606-86) felt, can effectively prevent the axle box water inlet with ￠ 120 * 136 dust rings;
2, owing to adopted the dust ring seal form, corresponding end cap is improved to the double flute sealing by former single groove sealing, and a road sealing groove reaches the anti-water inlet of sealing effect with dust ring, and another road sealing groove can store I type lithium base grease.But I type lithium base grease effectively lubricating end cap, axletree, bearing etc. reduce the wear problem between each assembly parts, and the dust ring enhanced leaktightness prevents the axle box water inlet.Greatly reduce the turnover rate of parts such as axletree, bearing simultaneously, saved fund;
3, according to actual needs, improved the design of cover during axle box is formed, the shaft shoulder, no chamfering have been arranged before upgrading professional title and rank by applying rules for other sectors; Remove the shaft shoulder after upgrading professional title and rank by applying rules for other sectors, increased chamfering, can effectively save cost.This design helps overlapping the assembling with axletree, cover and dust ring etc.

The specific embodiment
Below, in conjunction with the accompanying drawings the utility model is further described again:
As shown in Figure 1, the axletree two ends assembling axle box of forming in section of jurisdiction car traveling portion.Axle box is to be made of cover 1, dust ring 2, end cap 3, abrasion plate 4, adjusting pad 5, bearing 6, spindle nose back-up ring 7, locking iron wire 8, packing ring 9, screw 10, rear side housing 11, journal box body 12.Cover 1 is an interference fit with axletree.Overlap 1 end and be loudspeaker mouthful shape (see figure 3), end cap 3 is inserted in 1.End cap 3 is the double flute sealing, and a road sealing groove is equipped with dust ring 2, and dust ring 2 is positioned at 3 of cover 1 and end caps, and another road sealing groove can store the butter (see figure 5).7 of end cap 3 and spindle nose back-up rings are equipped with bearing 6, and bearing 6 models are 97502E; Locking iron wire 8, packing ring 9 and screw 10 are housed on the spindle nose back-up ring 7; Spindle nose back-up ring 7 bottoms are provided with rear side housing 11, and journal box body 12 embeds end caps 3 and 11 of rear side housings, and with screw that rear side housing 11 and adjusting pad 5, journal box body 12 is fastening, journal box body 12 outsides are equipped with abrasion plate 4.
The lubricated I type lithium base grease that adopts of axle box, oil mass is equivalent to 1/3～1/2 of the inner clearance volume of axle box.
