Abstract
(57)【要約】本公報は電子出願前の出願データであるた

Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は鉄道車両用軸箱に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to an axle box for a railway vehicle.
鉄道車両用の軸箱は、大きな荷重が作用するため軸箱本
体、前蓋、後蓋ともに鋳鉄あるいは鋳鋼などの鉄系金属
によって成形されていた。Because axle boxes for railroad vehicles are subject to large loads, the axle box body, front cover, and rear cover are all made of ferrous metals such as cast iron or cast steel.
その後、軸箱本体を鉄系金属にて成形し前蓋あるいは後
蓋を軽合金で成形した軸箱も使用されている。この軸箱
は軽量化と美観を追求したものであるが、最近では軸箱
本体、前蓋、後蓋をアルミニウムなどの軽合金で成形し
た軸箱も開発されている。Later, axle boxes were also used in which the main body of the axle box was made of ferrous metal and the front or rear cover was made of a light alloy. This axle box is designed to be lightweight and aesthetically pleasing, but recently axle boxes with the main body, front cover, and rear cover made of light alloys such as aluminum have also been developed.
この場合、軸箱本体の内面の摩耗を防止するために鉄製
の環状スリーブが嵌着されているが、スラスト荷重によ
って前蓋あるいは後蓋が損耗して耐用寿命が著しく縮減
することをしばしば経験するものである。In this case, a steel annular sleeve is fitted to prevent wear on the inner surface of the axle box body, but it is often experienced that the front or rear cover is worn out due to thrust loads, significantly shortening its service life. It is something.
このアルミニウム製軸箱は、鉄製軸箱に較べて密度は約
１７３と軽量であるが１機械的性質は約１／２であるた
め鉄製軸箱と同等の剛性を付与するためには、軸箱自体
が大型化し大きな空間を占有するばかりでなく、製造原
価も高騰するという好ましからざる結果を招くことにな
る。This aluminum axle box has a density of about 173, which is lighter than an iron axle box, but its mechanical properties are about 1/2, so in order to give it the same rigidity as an iron axle box, it is necessary to This not only increases the size and occupies a large amount of space, but also causes undesirable results such as a rise in manufacturing costs.
本発明の目的は、軸箱の重量を軽減し、かつ適当な剛性
を付与し得る鉄道車両用軸箱を提供するものである。An object of the present invention is to provide an axle box for a railway vehicle that can reduce the weight of the axle box and provide appropriate rigidity.
本発明の鉄道車両用軸箱は、軸箱本体と前蓋と後蓋とか
らなる軸箱であって、軸箱本体を軽合金で成形し、前蓋
及び／又は後蓋を鉄系金属にて成形したものである。The axle box for a railway vehicle of the present invention is an axle box consisting of an axle box body, a front cover, and a rear cover. It was molded by
以下本発明の実施例を図面に基いて詳細に説明する。第
１図は軸箱の正面図、第２図は第１図のＡ−Ａ断面図で
ある。Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of the axle box, and FIG. 2 is a sectional view taken along line AA in FIG.
本発明の軸箱を構成する主要部品の仕様は下記の通りで
ある。The specifications of the main parts constituting the axle box of the present invention are as follows.
従来の軸箱を構成する主要部品の仕様は下記の通りであ
る。The specifications of the main parts that make up a conventional axle box are as follows.
上記の通り、前蓋、後蓋をアルミニウムで成形した従来
品の合計重量は４０．１ｋｇであるのに対し、本発明に
よる軸箱の主要構成部品４点の合計重量は３４．８ｋｇ
であり、約１３％低減し、かつ軸箱としての剛性も著し
く向上した。As mentioned above, the total weight of the conventional product in which the front and rear covers are molded from aluminum is 40.1 kg, while the total weight of the four main components of the axle box according to the present invention is 34.8 kg.
This was reduced by approximately 13%, and the rigidity of the axle box was also significantly improved.
前蓋１と後蓋２とは軸箱本体３を貫通せるボルト４によ
って締め付けられているので剛性の向上とともに耐用寿
命を大幅に増大し得たものである。Since the front cover 1 and the rear cover 2 are tightened by bolts 4 that pass through the axle box body 3, the rigidity is improved and the service life is greatly extended.
なお、５は鉄製の環状スリーブである。Note that 5 is an annular sleeve made of iron.
本実施例では前蓋及び後蓋をアルミニウムで成形したが
、必要に応じて前蓋のみ、あるいは後蓋のみをアルミニ
ウムで成形することも勿論可能である。In this embodiment, the front cover and the rear cover are made of aluminum, but it is of course possible to make only the front cover or only the rear cover made of aluminum, if necessary.
以上の説明で明らかなように１本発明の鉄道車両用軸筒
は前蓋及び／又は後蓋を鉄系金属にて成形したため、前
蓋、後蓋で多くの荷重を支承し、軽合金製の軸箱本体に
加わる荷重が緩和され、軸箱としての重量軽減、剛性向
上、寿命増大に大きな効果を得たものである。As is clear from the above explanation, 1. Since the front cover and/or rear cover of the railway vehicle shaft cylinder of the present invention is formed of iron-based metal, the front cover and rear cover can bear a large amount of load, and the shaft cylinder is made of light alloy. The load applied to the main body of the axle box has been reduced, resulting in significant effects in reducing the weight of the axle box, improving its rigidity, and increasing its lifespan.
