Abstract

A railway axlebox comprises an axlebox housing (1, 10), whereby the outer surface of the axlebox housing (1, 10) is equipped with a sign (6) being different from a front end cover (3) of the axlebox housing (1, 10), being fixedly fitted to the said housing and having on the side facing outwards from said housing a marking incorporating arbitrary information (8).

Description

D e s c r i p t i o n
Marking of railway axle box
Axlebox housings for railway vehicles are equipped with bearings in which the wheel axles of the railway vehicle are supported. These axlebox housings are usually made from grey cast iron or nodular cast iron.
The axleboxes are equipped with different types and sizes of bearings in accordance with the expected conditions under which the railway vehicle in question shall operate.
For this reason the outside of the axlebox housing is provided with a marking, which indicates axlebox details, such as name or symbols for railway operator, production lot number, etcetera. Such details have earlier been fitted to the housing at the foundry by manual stamping of the cast housing with relevant details, which is a time consuming work, and which requires certain accuracy and skill of the person making the stamping for giving an easily interpreted and appealing marking.
So are object of the present invention is to create a railway axlebox and also a method for producing the axlebox so that marking of a railway axlebox housings can be realized in a much less time-consuming manner. This object is solved by subject of claims 1, 9 and 14. The dependent sub-claims define more in detail the preferred solutions of the invention.
So with advantage it is easier and therewith also more cost effective to create said sign as a kind of type plate and/or logo plate separately from the axlebox housing and then to fix it to axlebox housing than to stamp it manually in the cast of the axlebox housing as it is done up to now. Further it is easier to fulfill different demands of different railway companies in view of the kind of information and/or logos they want to have on the type and/or logo plate, because only the type and/or logo plate varies but not the axlebox itself.
If the sign is a steel plate it can be connected to the axlebox housing by welding. Therewith a reliable and durable connection for the whole life time of the axlebox is ensured with advantage. Further the information can be engraved in the steel plate e.g. by laser technology or characters can be fixed on the plate being raised in view of the plate, e.g. by laser welding. This ensures again with advantage that the information stays readable over the whole life time of the axlebox even in view of the comparatively hard operation and weather conditions a axlebox is exposed. Thereby also the sign can be designed the way that is not affected by corrosion.
Hereinafter the invention will be described with reference to a non-limiting embodiment illustrated in the accompanying drawing, in which
Fig. 1 is an end view of an axlebox housing.
Fig. 2 is a planar view of a sign to be mounted to the axlebox housing.
Fig. 3 is a side view of the sign according to Fig. 2.
Fig. 4 is a portion of another axle box housing in bigger scale, and Fig. 5 shows in a planar view a sign corresponding to that according to Fig. 2.
In the embodiment illustrated in Fig. 1 the housing 1 is a cast housing with integral supports 2 for not shown suspension springs formed in the lower beam of the housing.
An end cover 3 is bolted to the housing. The manufacturer name 4 has been formed in the axlebox housing or in the end cover in connection to the molding thereof.
However, there is also a desire from the railway operator to have the name or symbol attached to the axlebox, and this is traditionally made in the forgery by manually stamping the name, symbol and/or details about the manufacture, size and performance of the bearings, which are mounted in the axlebox housing 1, etcetera. This is a time consuming work.
However it is now proposed to provide such a marking with aid of a sign 6, which can be attached to the external side of the axlebox housing 1 or its end cover 3 at a specific position 5, which has been prepared in advance.
The said sign 6 is preferably, but not necessarily a steel plate (see for instance Figs, 2 and 3), which can be welded to the intended position 5 on the axlebox housing 1 or its end cover 3, and which sign can be pre-marked with any desired information, e.g. by an appropriate printing technique, such as laser-marking or in any other appropriate manner, thus that it holds the desired information and can easily be attached in position, without the need of stamping the details in the foundry.
The material of the sign 6 can of course also be an appropriate plastic material, and it can for instance, instead of being welded to the intended position 5 on the axlebox housing or the axlebox end cover, be fitted by gluing with an appropriate adhesive. In other embodiments the sign of an appropriate material can be also fixed by soldering.
The position 5 for the intended attachment of the sign is preferably bordered by a guiding ridge 7, thus that the surface of the position 5 is recessed for facilitating the correct positioning of the sign 4 at the fitting thereof.
As can be seen in Fig. 2, the sign 4 is preferably in the form of an escutcheon, which in the embodiment illustrated is just marked with the initials 8 of the railway operator (in the embodiment illustrated Deutsche Bahn).
Fig. 3 shows a side view of the sign 6, showing that the sign is very thin and has the symbols or initials 8 affixed at one side, whereas the opposite side is intended to be affixed to the recessed position 5 on the axlebox housing and/or its end cover.
In Fig. 4 is shown in bigger scale, a portion of an axlebox housing 10, the front cover 11 of which has the manufacturer name 4 formed therein during the molding process. In one of the upper corners of the housing has been formed a position 5, which is preferably recessed relative to surrounding surface of the axlebox housing and/or has a raised guiding ridge 7 along at least a portion of the position, e.g. on three sides for facilitating insertion of a sign (see Fig. 5) to be attached to the surface in said position 5. The sign 6 as shown in Fig. 5 can have the logotype of the railway operator such as illustrated in Fig. 2, and/or further specific information which is desirable to have attached to the axlebox. In this figure the sign is shown without any marking at all just to indicate that the information given thereon is completely arbitrary.
As intimated with broken lines in Fig. 4, it is also possible to have a further area 9 for attachment of a further sign, which can have the same information as the position 5 and/or information relating to the properties of the bearing assembly to be housed in the axlebox housing, etcetera.
The primary advantage of the method and the marking described is the elimination of the necessity of manually stamping information on the just cast axlebox housing in the forgery, and the possibility of providing the sign with appropriate information by means of a proper printing technique, which can be attached to the axlebox housing and/or its end cover at a suitable time after the molding thereof.
The invention is not limited to the embodiments illustrated in the accompanying drawings and described in connection thereto, but modifications and variants are possible within the scope of the appended claims.
