Description
【0001】[0001]
この考案は、フリンクションローラーコンベヤの駆動軸の接続部の軸受構造に 関する。 The present invention relates to a bearing structure of a connection portion of a drive shaft of a friction roller conveyor.
【0002】[0002]
フリクションローラーコンベヤにおいては、駆動軸を接続してコンベヤ長さに 対応しており、この接続部を軸受ベアリングに軸受けし軸受構造としていた。従 前においてもこの駆動軸の接続部は、その接続端を半切構造とし、相互にこの半 切部を重合してこの重合部を軸受ベアリングに軸受けしていた。 In the friction roller conveyor, a drive shaft is connected to correspond to the conveyor length, and the bearing structure is formed by bearing this connection part on a bearing bearing. Even in the past, the connecting portion of the drive shaft had a half-cut structure at its connecting end, and the half-cut portions were superposed on each other to bear the superposed portion on the bearing.
【0003】[0003]
従前のこの軸受構造は、上記重合した半切構造部を直接軸受ベアリングのイン ナーレース内側に軸受けするか、該インナーレースと半切構造部との間にブッシ ュを圧入して軸受構造としていた。 前者の軸受構造では、接続部である半切構造部とベアリングインナーレースと の間に隙間が生ずることと、駆動軸は常時負荷を受けていることとにより、上記 半切構造部とベアリングインナーレース間で滑りを生じ摩耗現象を生ずるという 問題点があった。 また、後者の軸受構造においても、上記半切部を重合する構造のために、この 半切構造部で屈曲現象を生じて回転するため、ブッシュと半切構造部との間で均 一な面接触が得られず、その結果面圧不足を生じブッシュが摩耗するという問題 点があった。 In this conventional bearing structure, the polymerized half-cut structure portion is directly supported on the inner side of the inner race of the bearing bearing, or a bush is press-fitted between the inner race and the half-cut structure portion to form a bearing structure. In the former bearing structure, a gap is created between the half-cut structure part, which is the connection part, and the bearing inner race, and the drive shaft is constantly receiving a load. There was a problem in that it caused slippage and an abrasion phenomenon. Also, in the latter bearing structure, the structure in which the above-mentioned half-cut portion overlaps causes a bending phenomenon in this half-cut structure portion to rotate, so that uniform surface contact is obtained between the bush and the half-cut structure portion. However, as a result, the surface pressure becomes insufficient and the bush wears.
【0004】 本考案は、従来の技術の有する上記の問題点に鑑みてなされたもので、その目 的とするところは、フリクションローラーコンベヤの駆動軸の軸受接続部におい て、振動あるいは摩擦による摩耗を少なくして耐用性の高い新規な軸受構造を提 供しようとするものである。The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to prevent wear due to vibration or friction at the bearing connection portion of the drive shaft of the friction roller conveyor. It is intended to provide a new bearing structure with reduced wear and high durability.

上記目的を達成するために、本考案におけるフリクションローラーコンベヤの 駆動軸軸受構造は、駆動軸の接続部を相互に半切構造としてこの半切構造部を重 合し、何ずれか片側の半切構造部に軸心方向に向かう受け孔を形成し、この受け 孔にキー部材に突設した挿入ピンを挿入することによりキー部材を半切構造部の 表面に組付け、キー溝を形成したブッシュをこのキー溝を上記キー部材に合致さ せて軸受ベアリングのインナーレース内側に圧入してなることを特徴とする。 In order to achieve the above object, the drive shaft bearing structure of the friction roller conveyor according to the present invention is such that the connecting parts of the drive shafts are made into half-cut structures and these half-cut structure parts are overlapped with each other, so that the half-cut structure part on one side is slightly offset. A key hole is formed in the axial direction, and the key member is assembled to the surface of the half-cut structure by inserting an insertion pin protruding from the key member into this hole. Is fitted into the inner race of the bearing and is press-fitted to the key member.

本考案軸受構造では、駆動軸の接続部の何ずれかの半切構造部に形成した受け 孔に、キー部材に突設した挿入ピンを挿入してキー部材を接続部表面に組付け、 接続部とベアリングインナーレースとの間に圧入するブッシュに上記キー部材を 受け入れるキー溝を形成してあるから、半切構造部の重合によって構成された接 続部とブッシュとベアリングインナーレースとが一体化され、これらが一致して 回転する。 In the bearing structure of the present invention, the key member is assembled on the surface of the connecting portion by inserting the inserting pin protruding from the key member into the receiving hole formed in the half-cut structure portion of the connecting portion of the drive shaft. Since a key groove for receiving the above key member is formed in the bush press-fitted between the bearing inner race and the bearing inner race, the connection portion formed by overlapping the half-cut structure portion, the bush, and the bearing inner race are integrated, These match and rotate.

【0008】 フリクションローラコンベヤはその長さが比較的長く、その全長に亘って駆動 軸が位置付けられるが、この駆動軸は複数の駆動軸が接続されて配置される。こ の駆動軸の接続部は、各軸の接続端4,4を半切構造部5,5としてある。即ち 軸端が半円状になるように切り込みを入れ、その半分を切り取って構成してある 。そして何ずれか一方の接続端4の半切構造部5に軸心方向に向かう受け孔6を 形成してある。The friction roller conveyor has a relatively long length, and a drive shaft is positioned along the entire length thereof, and the drive shaft is arranged with a plurality of drive shafts connected thereto. The connecting portion of this drive shaft has connecting ends 4 and 4 of each shaft as half-cut structure portions 5 and 5. In other words, it is constructed by cutting in such a way that the shaft end becomes semicircular and cutting out half of it. A receiving hole 6 extending in the axial direction is formed in the half-cut structure portion 5 at one of the connecting ends 4 at some displacement.
