Abstract
(57)【要約】本公報は電子出願前の出願データであるた
め要約のデータは記録されません。(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.
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.
〔従来の技術及び発明が解決しようとする問題点〕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、
前蓋ともに鋳鉄あるいはＵ鋼などの鉄系金属によって成
形されていた。[Problems to be solved by the prior art and the invention] Since large loads are applied to axle boxes for railway vehicles, the axle box itself,
Both the front lids were made of ferrous metals such as cast iron or U-steel.
その後、軸箱本体を鉄系金属にて成形し前蓋を軽合金で
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 molded from ferrous metal and the front cover was molded from a light alloy. This axle box is designed to be lightweight and aesthetically pleasing, but recently axle boxes with the main body and front 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 cover is worn out by thrust loads, significantly shortening its service life. .
このアルミニウム製軸箱は、鉄製軸箱に較べて密度は約
１／３と軽量であるが、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 1/3 of that of a steel axle box, which is lighter, but its mechanical properties are about 1/2, so in order to give it the same rigidity as an iron axle box, Not only does the axle box itself become larger and occupy a larger space, but the manufacturing cost also rises, which is an undesirable result.
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、軸箱本体と前蓋とからなる
軸箱であって、軸箱本体を軽合金で成形し、前蓋を鉄系
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 and a front cover, and the axle box body is molded from a light alloy and the front cover is molded from a ferrous metal.
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３点の合計重量は３０．４ｋｇであり
、約２４％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 whose front cover is molded from aluminum is 40.1 kg, whereas the total weight of the three main components of the axle box according to the present invention is 30.4 kg, which is approximately 24%. At the same time, the rigidity of the axle box has also been significantly improved.
前蓋１は軸箱本体２にボルト３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。なお、４は鉄製の環状スリーブである。Since the front cover 1 is fastened to the axle box body 2 with bolts 3, the rigidity is improved and the service life is greatly extended. Note that 4 is an annular sleeve made of iron.
以上の説明で明らかなように、本発明の鉄道車両用軸箱
は前蓋を鉄系金属にて成形したため、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, since the front cover of the axle box for a railway vehicle of the present invention is formed of iron-based metal, the load applied to the axle box body made of light alloy is alleviated, and the weight of the axle box as a box is reduced. This has had a significant effect on improving rigidity and extending life.
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。FIG. 1 is a front view of the axle box, and FIG. 2 is a sectional view taken along line A--A in FIG. 1.
