Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案はローラ駆動軸に関するものであり、更に詳しくは、紡績機のデリベリ ローラ駆動軸の連結構造に係るものである。 The present invention relates to a roller drive shaft, and more particularly, to a connection structure of delivery roller drive shafts of a spinning machine.

【0002】[0002]

【従来の技術】[Prior art]

従来、多数の紡績ユニットを並設した紡績機のデリベリローラは、適宜の数の 紡績ユニットを1スパンとして、該1スパン毎に設けた機台フレームに回転自在 に支持したローラ駆動軸上に一体に設けられており、その一例を図2に示し、以 下に説明する。 Conventionally, a delivery roller of a spinning machine in which a large number of spinning units are arranged side by side has an appropriate number of spinning units as one span, and is integrally mounted on a roller drive shaft rotatably supported by a machine frame provided for each span. It is provided, an example of which is shown in FIG. 2 and described below.

【0003】 図2において、デリベリローラDを設けたローラ駆動軸21は、機台フレーム 22に、ブラケット23で固定されているベアリング24に回転自在に支持され ている。また、該ベアリング24の図中右側をローラ駆動軸21の連結部分25 として、該連結部分25において、互いに隣接するローラ駆動軸21,21の端 部21a,21bを半割円筒カップリング26,キー27等で連結し、機台端部 に設けた図示しない動力源により全錘一斉に駆動回転している。28,29はス ペーサである。In FIG. 2, a roller drive shaft 21 provided with a delivery roller D is rotatably supported by a bearing 24 fixed to a machine frame 22 by a bracket 23. Further, the right side of the bearing 24 in the drawing is used as a connecting portion 25 of the roller driving shaft 21, and at the connecting portion 25, the end portions 21a and 21b of the roller driving shafts 21 and 21 which are adjacent to each other are connected to the half-cylindrical coupling 26 and the key. All the spindles are driven and rotated all together by a power source (not shown) provided at the end of the machine base. 28 and 29 are spacers.

【0004】 このようなローラ駆動軸21においては、各ローラ駆動軸21の連結部分25 において、カップリング26が露見しており外観及び安全上好ましくないので、 別途カバー30等を設けていたが、ベアリング24等の交換の際にはカバー30 を外さなければならず、作業性が悪かった。In such a roller drive shaft 21, the coupling 26 is exposed at the connecting portion 25 of each roller drive shaft 21 and it is not preferable in terms of appearance and safety. Therefore, the cover 30 and the like are provided separately. When replacing the bearing 24 and the like, the cover 30 had to be removed, and workability was poor.

【0005】 また、ベアリング24とカップリング26とを並置しているため幅をとり紡績 機の機台設計上不利であった。尚且つ、図2中右側の一方のローラ駆動軸21の 端部21bは、ローラ駆動軸21がベアリング等で支持されていないためカップ リング26に過度の負担がかかった。Further, since the bearing 24 and the coupling 26 are juxtaposed to each other, the width is wide, which is disadvantageous in designing the base of the spinning machine. Further, at the end portion 21b of the roller drive shaft 21 on the right side in FIG. 2, since the roller drive shaft 21 is not supported by bearings or the like, the coupling 26 is overloaded.

【0006】[0006]

【考案が解決しようとする課題】[Problems to be solved by the device]

本考案は、従来の技術のこのような点に鑑みて、取付けスペースを削減でき、 且つ、外観上も優れているのみならず、ベアリング交換時等において駆動軸を容 易に取外し可能なローラ駆動軸の連結構造を提供することを目的とするものであ る。 In view of the above-mentioned problems of the conventional technology, the present invention not only has a small installation space and is excellent in appearance, but also has a roller drive in which the drive shaft can be easily removed when the bearing is replaced. It is intended to provide a shaft connecting structure.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

互いに隣接するローラ駆動軸の端部を半割円筒カップリングで連結し、且つ、 該連結部分の両側に設けたベアリング適宜位置に設けられた半割の下部ハウジン グ内に支持し、半割の上部ハウジングで上記カップリングを包覆した。 The ends of the roller drive shafts adjacent to each other are connected by a half-cylinder coupling, and the bearings provided on both sides of the connecting part are supported in a half-lower housing which is provided at an appropriate position. The upper housing covered the coupling.

【0008】[0008]

【作用】[Action]

ハウジングを開き、半割カップリングを分離して外せば、ローラ駆動軸はベア リングごとに取外し可能となる。 If the housing is opened and the half coupling is separated and removed, the roller drive shaft can be removed for each bearing.

The connecting portion 2 includes a coupling C, a bearing B, and It is composed of the housing H of the bearing B.

【0011】 デリベリローラ駆動軸LにはデリベリローラDが一体に形成され、該デリベリ ローラ駆動軸Lの両の端段部La,LbにはキーKに係合するキー溝Lk,Lk が設けてあり、且つ、ベアリングBが夫々嵌合される。A delivery roller D is integrally formed with the delivery roller drive shaft L, and both end step portions La and Lb of the delivery roller drive shaft L are provided with key grooves Lk and Lk for engaging with the key K. Moreover, the bearings B are fitted into each other.

【0012】 カップリングCは、半割円筒カップリングCa,Cbよりなり、うち一方の半 割カップリングCaには上記キーKに係合するキー溝Ckが設けられている。The coupling C is composed of half-cylinder couplings Ca and Cb, and one of the half-couplings Ca is provided with a key groove Ck that engages with the key K.

【0013】 ハウジングHは半割円筒状の上部ハウジングHa、及び下部ハウジングHbよ りなり、各ハウジングHa,Hbの両端He,HeはベアリングB,Bの支持部 分となっている。また下部ハウジングHbの下側周面には取付部Hcが設けられ ており、該取付部HcにおいてボルトS1,S2により機台フレームFに固定さ れる。The housing H is composed of an upper housing Ha and a lower housing Hb each having a half-cylindrical shape, and both ends He and He of the respective housings Ha and Hb serve as supporting portions for the bearings B and B. A mounting portion Hc is provided on the lower peripheral surface of the lower housing Hb, and is fixed to the machine frame F by bolts S1 and S2 at the mounting portion Hc.

【0014】 以下、駆動軸L,Lの取付け及び取外しについて説明する。The attachment and detachment of the drive shafts L, L will be described below.

【0015】 駆動軸L,Lの両端部La,LbにベアリングB,Bを嵌合して、該ベアリン グB,Bを下部ハウジングHbの両端部He,Heに収めれば、駆動軸L,Lは 下部ハウジングHbに回転自在に支承される。If the bearings B and B are fitted to both ends La and Lb of the drive shafts L and L and the bearings B and B are housed in both ends He and He of the lower housing Hb, L is rotatably supported on the lower housing Hb.

【0016】 次いで、各駆動軸端部La,Lbのキー溝Lk,Lkを一致させつつ、該キー 溝Lk,LkにキーKを挿入し、該キーKに一方の半割カップリングCaのキー 溝Ckを係合させながら、該半割カップリングCaと他方の半割カップリングC bを駆動軸端部La,Lbに外装し、それらを図示しないボルトで一体にすれば 、各駆動軸L,Lは連結される。Next, while aligning the key grooves Lk and Lk of the drive shaft end portions La and Lb with each other, the key K is inserted into the key grooves Lk and Lk, and the key of the one half coupling Ca is inserted into the key K. While engaging the groove Ck, the half-coupling Ca and the other half-coupling Cb are mounted on the drive shaft end portions La and Lb, and they are integrated by bolts (not shown). , L are connected.

【0017】 更に、上部ハウジングHaを下部ハウジングHbに合わせベアリングB,Bを 各ハウジングHa,Hb間に固定しながら、図示しないボルトでそれらを一体に すれば、駆動軸L,Lの取付作業は完了する。Further, when the upper housing Ha is aligned with the lower housing Hb and the bearings B, B are fixed between the housings Ha, Hb, they are integrated with a bolt (not shown), so that the drive shafts L, L can be mounted easily.
