Abstract
The utility model discloses a wheel pair device of a hollow axle, which aims at modifying connection manners of conventional axle case bodies with hollow axles. The technical scheme includes that a seal end cover at a side end of a hollow axle and a seal end cover on the side of an axle case body are respectively sealed and connected, when in need of failure detection of an inner hole, a user needs only to sequentially detach the two seal end covers without detaching and reinstalling the axle case body, and the wheel pair device realizes a wheel pair device modification method with reliable sealed connection and easiness in accurate restore. The wheel pair device mainly comprises the hollow axle, wherein wheels in pair are sleeved at two ends of the hollow axle, and the axle case body is connected to a neck of the hollow axle and outside the wheels via bearings. An axle case front cover and an axle case rear cover are respectively connected to two side ends of the axle case body, and axle end dust-proof covers are connected to the ends of the hollow axle in a sealed manner.
Description
Technical field
The utility model is to be applied to the wheel of guideway vehicle to device, and concrete is to improve existing sealing and connection structure in the two side ends of tubular axle, belongs to mechanical manufacturing field.
Background technology
Along with improving constantly of domestic motor train unit running velocity, for how guaranteeing that the operation of rail vehicle truck high-speed secure has proposed higher designing requirement.
For alleviating the weight of existing guideway vehicle own, to select for use under the prerequisite of high mechanical properties steel more, the axletree of existing vehicle can be a hollow structure.Sealing at tubular axle is one of gordian technique factor, enters to prevent tubular axle generation corrosion to prevent impurity, moisture.But after operation a period of time, still need open the structure that is tightly connected of tubular axle two side ends,, for example can adopt ultrasonic probe to stretch in the endoporus of tubular axle to implement inner carrying out flaw detection.
The existing axle box device that connects tubular axle, consider increases sealing property and installation reliability morely.When needs carry out the endoporus flaw detection, generally need dismounting journal box body end cap or even directly dismantle journal box body, therefore endoporus flaw detection each time all need be dismantled a plurality of parts and experience than farm labourer's phase, and also need possess higher precision when reinstalling journal box body and be connected with the accurate of truck frame guaranteeing.
The utility model content
The wheel of tubular axle described in the utility model is to device, its design goal is to address the above problem and is improved at the connection mode of existing journal box body and tubular axle, 2 layers of end cover by tubular axle side end, journal box body sidepiece are tightly connected respectively, only need dismantle 2 layers of end cover successively when needs carry out the endoporus flaw detection gets final product, need not journal box body itself is dismantled and reinstalled, realized that a kind of positiver sealing connects, is easy to again the accurate wheel that restores device is improved one's methods.
For realizing above-mentioned design goal, the wheel of described tubular axle mainly includes device:
One tubular axle,
Be arranged with a pair of wheel at the tubular axle two ends,
Axle journal place at lateral wheel, tubular axle is connected with journal box body by bearing.
The difference with the prior art part is that the journal box body two side ends is connected with journal box front cover and journal box rear cover respectively, is connected with the axle head cover of dust at the port sealing of tubular axle.
As above-mentioned basic scheme feature, journal box front cover and journal box rear cover have upwards been realized sealing to journal box body from front and back, and with respect to the dismounting journal box body, the dismounting journal box front cover seems more easy.
And, dismantle and reinstall journal box front cover and can't have influence on connection structure between journal box body and the truck frame, therefore can't constitute influence to the connection reliability of whole bogie truck.
After opening journal box front cover, only need the axle head cover of dust is unloaded the endoporus that the flaw detection probe can be put into tubular axle.
Based on above-mentioned design concept, the utility model also provides following improvement project, need not to dismantle the port of opening tubular axle on the basis of journal box front cover, promptly further simplifies the dismounting operation and reduces to dismantle the volume of parts.
Be provided with central through hole at journal box front cover, be sealedly connected with a serum cap at the central through hole place.
That is to say, open serum cap and be equivalent to dismantle journal box front cover, expose the axle head cover of dust from the outside so that dismounting.
For improving the convenience of the described axle head cover of dust of dismounting further, the axle head cover of dust is connected the port of tubular axle by negative thread or outside thread.
For improving the convenience of the described serum cap of dismounting further, be provided with the ring-type draw-in groove in the central through hole outer rim of journal box front cover, serum cap is buckled on the ring-type draw-in groove.
As mentioned above, the wheel of the utility model tubular axle has the following advantages to device:
Adopt 2 layers of end cover structure, need not journal box body itself is dismantled, realized a kind ofly can positiver sealing connecting, can make things convenient for again the wheel of endoporus flaw detection structural development.
Dismounting end cap and endoporus flaw detection operation, can't have influence on wheel to and bogie truck between connection reliability, can not constitute the potential safety hazard of high-speed cruising.
Description of drawings
Now in conjunction with the following drawings the utility model is described further.
Fig. 1 is described cut-away section scheme drawing of taking turns device;
In last figure, have journal box body 1, journal box front cover 2, journal box rear cover 3, bearing 4, axle head cover of dust 5, serum cap 6, tubular axle 7 and wheel 8.
The specific embodiment
Be arranged with a pair of wheel 8 at tubular axle 7 two ends.
Axle journal place at wheel 8 outsides, tubular axle 7 is connected with journal box body 1 by bearing 4, and journal box body 1 two side ends is connected with journal box front cover 2 and journal box rear cover 3 respectively.
Journal box front cover 2 is provided with central through hole, and the central through hole outer rim is provided with the ring-type draw-in groove, and serum cap 6 is buckled on the ring-type draw-in groove.
In the port of tubular axle 7, be sealedly connected with axle head cover of dust 5 by negative thread or outside thread, axle head cover of dust 5 plays effects such as dustproof, waterproof from the outside to the endoporus of tubular axle 7.
When tubular axle 7 need regularly carry out the endoporus flaw detection, pull down serum cap 6 earlier, dismantle axle head cover of dust 5 then and ultrasonic probe can be stretched in the endoporus of tubular axle 7.
