【考案の詳細な説明】
この考案は、走行ローラの摺動部に塵介が浸入
するのを防止するようにした防塵リングを具備し
た搬送用チエーンに関する。[Detailed Description of the Invention] This invention relates to a conveyance chain equipped with a dustproof ring that prevents dust from entering the sliding portion of the traveling rollers.
粉粒体を搬送するエプロンコンベヤや、熱鋼片
を搬送するコンベヤには、搬送物の粉塵が飛散し
或はスケールが落下するなど悪環境で使われてい
るものが多い。 Many apron conveyors for conveying powder and granular materials and conveyors for conveying hot steel pieces are used in adverse environments where dust from the conveyed material is scattered or scales fall.
このような悪環境で使われているチエーンは塵
介が走行ローラの隙間から摺動部に浸入し潤滑油

らに塵介が隙間に固着して走行ローラの回転不良
の原因になつて外径に多角形状の偏摩耗を生起
し、これがためチエーンの寿命を著しく短縮し、
また走行抵抗の増大によつて動力の損失を大きく
するなどの重大な欠点があつた。 In chains used in such adverse environments, dust enters the sliding parts through the gaps between the running rollers, reducing the effectiveness of the lubricating oil and accelerating wear. This causes malrotation of the chain, causing polygonal uneven wear on the outer diameter, which significantly shortens the life of the chain.
It also had serious drawbacks such as increased power loss due to increased running resistance.
従来は、この対策として第５図に示す実公昭55
−52114号公報に開示された軸受メタル（ブシ
ユ）の端部に段部を形成し、段部の端面に当接す

た。 Conventionally, as a countermeasure for this, the Jiko Kosho 55 shown in Figure 5 was used.
A method disclosed in Japanese Patent No. 52114 has been attempted in which a stepped portion is formed at the end of a bearing metal (bushing) and a dustproof ring is fitted into the end surface of the stepped portion.
しかしこの方法は、高価で汎用性に乏しく、且
つ、走行ローラの端面とリンクプレートとの隙間

が付着し、回転不良を生起する欠点が依然と残
り、完全に欠点を解決するには至らなかつた。 However, this method is expensive, lacks versatility, and does not have a dust-proofing function for the gap between the end face of the running roller and the link plate, so it still has the disadvantage that dust adheres to the gap and causes rotation failure. However, the shortcomings could not be completely resolved.

ンを得ることを目的としたものである。 The present invention was devised in view of this situation, and includes forming a dust-proof ring loose-fitting part at the end of the running roller, and adding a width to the loose-fitting part of the dust-proof ring approximately equal to the depth of the loose-fitting part of the dust-proof ring. A dustproof ring with the same inner diameter smaller than the width of the link plate and the outer diameter of the washer is fitted loosely, making it inexpensive and versatile, and reducing the gap between the end face of the running roller and the link plate and washer. The aim is to obtain a chain that also has a dustproof function.

FIGS. 1 and 2 show the first embodiment, in which 1 is a conveyance chain with a pair of left and right pin link plates 2 and a pair of right and left bushes. The bush link plates 3, 3 are arranged alternately, and holes are provided at both ends of the bush link plates 3, 3 (one end is not shown).
A bushing 4 is press-fitted and fixed to the bushing 4, and a running roller 5 is loosely fitted to the outer periphery of the bushing 4.

Washers 12, 12 are fitted on the outside thereof, and retaining pins 13, 13 are used to prevent them from coming off. Further, annular grooves 14, 14 are formed at the inner ends of the running rollers 11, 11, and the annular grooves 14, 14 have approximately the same width as the depth H of the annular grooves 14, 14, and have an inner diameter of a pin link plate 15. , 15 are loosely fitted.

4', 14' have a depth H of the annular step portions 14', 14'.
Dust-proof rings 16', 16' having approximately the same width and having an inner diameter smaller than the outer diameter of the washers 12, 12 are loosely fitted.
叙上の構成を有するものであるから、チエーン
の走行にともなつて防塵リングは、リンクプレー
トまたは座金と、走行ローラの防塵リング遊嵌部
の底面とで形成された隙間Ａの間を遊動し、大半
は隙間Ａの中央に位置するものである。 As the chain runs, the dustproof ring moves freely between the gap A formed between the link plate or washer and the bottom surface of the dustproof ring loose fitting part of the running roller. , most of which are located in the center of gap A.

ラの端面との隙間Ｃの半分になり隙間が小さくな
ることによつて塵介が隙間から摺動部に浸入する
のを防止し、浸入量を極めて少なくするのであ
る。 When the dustproof ring is located at the center of the gap A, the gap B between the link plate or washer and the dustproof ring becomes half of the gap C between the link plate or washer and the end surface of the running roller, and the gap becomes smaller. This prevents dust from entering the sliding part through the gap and extremely reduces the amount of dust entering.
また走行ローラの防塵リング遊嵌部の底面と防
塵リングとの隙間Ｄは、ラビリンス効果を持つも
のであるから、隙間Ｄからの塵介の浸入も極めて
少なくするのである。 Furthermore, since the gap D between the dustproof ring and the bottom surface of the dustproof ring loose fitting part of the traveling roller has a labyrinth effect, the intrusion of dust through the gap D is also extremely reduced.
そして、摺動部に給油されている潤滑油の外部
への流出を防止し、給油間隔を長くすることもで
きるのである。 It is also possible to prevent the lubricating oil supplied to the sliding parts from leaking to the outside, and to lengthen the oiling interval.

を押圧して摺動する。 Also, when thrust force is applied to the running roller,
Since the depth of the loosely fitting part of the dustproof ring on the running roller and the width of the dustproof ring are approximately the same, the dustproof ring is stored in the loosely fitting part of the dustproof ring on the running roller, and is aligned with the end face of the running roller, and is attached to the link plate or washer surface. Press and slide.

The dust will be absorbed by the end face of the dustproof ring, so if the end face of the running roller is wear resistant, the dustproof ring does not need to be wear resistant, and soft materials such as mild steel, rubber, and resin can also be used. be.
本案は上述の作用構成を有するものであるから
ブシユに段部を形成する必要がなく、またブシユ
を持たないチエーンにも適用できるので安価で汎
用性がある。 Since the present invention has the above-mentioned working structure, there is no need to form a stepped portion on the bushing, and it can also be applied to a chain without a bushing, so it is inexpensive and versatile.
そして、リンクプレートまたは座金と走行ロー
ラ端面との摺動部への塵介の浸入も防止するの

ことがなく、チエーンの寿命を著しく増加させる
など、多くの効果を有するものである。 It also prevents dust from entering the sliding part between the link plate or washer and the end face of the running roller, so there is no increase in running resistance or rotation failure, and the life of the chain is significantly increased. It has many effects.

ある。 In the above embodiment, the running roller of the chain was described, but it may also be used as a conveyance support roller such as an accumulation conveyor, or it may be used as a running roller with a built-in rolling bearing or a conveyance support roller. However, similar effects can be achieved.
そして１個のローラの同一側端面に環状段部と
環状溝部を併設し、防塵リングを二重に使用する
と、ラビリンス効果が増大し、より大きい効果が
得られるものである。 If an annular step and an annular groove are provided on the same end face of one roller and a dustproof ring is used twice, the labyrinth effect is increased and a greater effect can be obtained.
