チェーンの構築
異なるサイズのローラーチェーンの構造を示した2つの例。
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.
The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
潤滑
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
また、汚れた環境下で使用せざるを得ず、サイズや動作上の理由から密閉できないチェーンも数多く存在します。例えば、農機具、自転車、チェーンソーなどに使われているチェーンなどが挙げられます。これらのチェーンは、潤滑や調整を怠り、摩擦の増加、効率の低下、騒音の増加、頻繁な交換を許容するオペレーターの場合、必然的に摩耗率が高くなります。
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a CHINAMFG film after application and repels both particles and moisture.
オートバイチェーンの潤滑
オートバイに搭載されるチェーンのように高速で動作するチェーンは、オイルバスと併用する必要があります。しかし、現代のオートバイではそれが不可能なため、ほとんどのオートバイ用チェーンはオイルバスなしで使用されています。そのため、オートバイ用チェーンは他の用途に比べて非常に早く摩耗する傾向があります。極端な力が加わり、雨、泥、砂、融雪剤などにさらされるからです。
Motorcycle chains are part of the drive train to transmit the motor power to the back wheel. Properly lubricated chains can reach an efficiency of 98% or greater in the transmission. Unlubricated chains will significantly decrease performance and increase chain and sprocket wear.
Two types of CHINAMFG lubricants are available for motorcycle chains: spray on lubricants and oil drip feed systems.
Spray lubricants may contain wax or PTFE. While these lubricants use tack additives to stay on the chain they can also attract dirt and sand from the road and over time produce a grinding paste that accelerates component wear.
Oil drip feed systems continuously lubricate the chain and use light oil that does not stick to the chain. Research has shown that oil drip feed systems provide the greatest wear protection and greatest power saving.
バリエーションデザイン
Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
自動車エンジンの大部分は、カムシャフトの駆動にローラーチェーンを使用している。非常に高性能なエンジンではギア駆動がよく用いられ、1960年代初頭からは一部のメーカーで歯付きベルトが使用されるようになった。
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
自転車チェーンの摩耗
The lightweight chain of a bicycle with derailleur gears can snap (or rather, come apart at the side-plates, since it is normal for the “riveting” to fail first) because the pins inside are not cylindrical, they are barrel-shaped. Contact between the pin and the bushing is not the regular line, but a point which allows the chain’s pins to work its way through the bushing, and finally the roller, ultimately causing the chain to snap. This form of construction is necessary because the gear-changing action of this form of transmission requires the chain to both bend sideways and to twist, but this can occur with the flexibility of such a narrow chain and relatively large free lengths on a bicycle.
Chain failure is much less of a problem on hub-geared systems (e.g. Bendix 2-speed, Sturmey-Archer AW) since the parallel pins have a much bigger wearing surface in contact with the bush. The hub-gear system also allows complete enclosure, a great aid to lubrication and protection from grit.
チェーンの強度
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[出典が必要]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

記憶を助けるために、同じ規格の主要な寸法をインチの分数で表したものを以下に示します(これは、ANSI規格で推奨される数値を選択した背景にある考え方の一部です)。
| ピッチ(インチ) | ピッチが表現される 8分の1ずつ | ANSI規格 チェーン番号 | 幅(インチ) |
|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |
| 3⁄8 | 3⁄8 | 35 | 3⁄16 |
| 1⁄2 | 4⁄8 | 41 | 1⁄4 |
| 1⁄2 | 4⁄8 | 40 | 5⁄16 |
| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
注:
1. ピッチとは、ローラーの中心間の距離です。幅とは、リンクプレート間の距離です(つまり、クリアランスを確保するためにローラー幅よりわずかに大きくなっています)。
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. 左側の数字は、ピッチを構成する8分の1インチの数を表します。
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
ISO規格に基づいて製造されたローラーチェーンは、アイソチェーンと呼ばれることもある。

モーターチェーンは、高温多湿の環境で使用できますか?
はい、モーターチェーンは高温多湿の環境でも使用できますが、いくつかの考慮事項があります。
高温:
高温環境下で運転する場合、高温に耐えられるモーターチェーンを選択することが重要です。高温用途向けのチェーンには、熱処理鋼や合金などの特殊な耐熱材料がよく使用されます。これらの材料は優れた耐熱性を持ち、高温下でも強度と性能を維持できます。
In addition to selecting the appropriate chain material, proper lubrication becomes even more critical in high-temperature environments. The lubricant used should have a high temperature rating to ensure adequate lubrication and prevent premature wear. Regular monitoring of the chain’s condition and lubrication levels is essential to maintain its performance and minimize the effects of heat.
湿度:
湿度の高い環境では、モーターチェーンの腐食や錆の発生リスクが高まります。この問題を解決するため、モーターチェーンには耐腐食性材料やコーティングが一般的に使用されます。ステンレス鋼製のチェーンや、特殊な耐腐食性コーティングを施したチェーンは、湿気や水分に対する優れた保護性能を発揮します。
湿度の高い環境では、湿気がチェーン内部に浸透して腐食を引き起こすのを防ぐため、適切なメンテナンスと潤滑が不可欠です。定期的な点検、清掃、そして防錆潤滑剤による潤滑を行うことで、チェーンの寿命を延ばし、性能を維持することができます。
It is important to note that while motor chains can be used in high-temperature or humid environments, their performance and lifespan can still be affected. It is recommended to consult the chain manufacturer for specific guidelines and recommendations regarding the use of motor chains in such conditions. Additionally, proper ventilation and environmental controls should be considered to minimize the impact of high temperatures or humidity on the chain’s performance.
モーターチェーンは重い負荷に耐えられるか?
はい、モーターチェーンは様々な用途で重負荷に対応できるように設計されています。考慮すべき要素は以下のとおりです。
1. チェーンの強度:モーターチェーンにはさまざまな強度定格があり、通常は最大許容張力または破断強度で測定されます。用途における想定される負荷に適した強度定格のモーターチェーンを選択することが重要です。強度定格の高いチェーンは、より重い負荷に対応できます。
2. チェーン材質:モーターチェーンは一般的に、優れた耐久性と耐荷重性を備えた高強度鋼または合金材料で作られています。材質の選択は、想定される荷重、環境条件、および規制基準など、特定の用途要件によって異なります。
3.チェーン設計:高負荷用途向けに設計されたモーターチェーンは、耐荷重能力を高めるために堅牢な構造を備えていることが多い。これには、より大きなピッチサイズ、より厚いプレート、硬化処理された部品、精密な製造などが含まれる。この設計により、チェーンは高負荷に伴う力や応力に耐えることができる。
4.潤滑:重荷重を扱うモーターチェーンにとって、適切な潤滑は不可欠です。潤滑は摩擦と摩耗を軽減し、スムーズな動作を確保し、チェーンの耐用年数を延ばします。また、適切な潤滑は過熱や腐食を防ぎ、チェーンの耐荷重能力への悪影響を回避します。
5. スプロケットの設計:モーターチェーンと噛み合うスプロケットは、重荷重の伝達において重要な役割を果たします。スプロケットは、チェーン全体に荷重を均等に分散させ、確実な噛み合いを実現するように設計する必要があります。頑丈で適切なサイズのスプロケットを使用することで、チェーンは過度の摩耗や破損を起こすことなく、重荷重を効果的に伝達できます。
重負荷用途のモーターチェーンを検討する際には、メーカーの仕様書やガイドラインを参照することが重要です。これらの資料には、引張強度、使用荷重制限、推奨安全係数など、チェーンの耐荷重能力に関する詳細な情報が記載されています。適切なチェーンの選定、定期的なメンテナンス、そして荷重制限の遵守は、重負荷下での安全かつ効率的な運転を確保するための鍵となります。
モーターチェーンとは何ですか?また、どのように使用されますか?
モーターチェーン(動力伝達チェーンとも呼ばれる)は、モーターやエンジンから機械やシステムの様々な部分に動力を伝達するために使用される機械装置です。相互に連結された一連のリンクで構成され、柔軟で耐久性のあるチェーンを形成します。
モーターチェーンは、自動車、産業機械、農業機械、コンベアシステムなど、幅広い用途で一般的に使用されています。モーターから車輪、ギア、スプロケット、プーリーなどの様々な部品へ回転運動と動力を伝達する上で、重要な役割を果たしています。
Here’s how a motor chain is typically used:
1. 動力伝達:モーターチェーンの主な機能は、モーターからシステムの他の部分に動力を伝達することです。モーターが回転すると、チェーンが駆動され、チェーンが接続されたコンポーネントを駆動することで、各コンポーネントが本来の機能を果たすことができます。
2. 速度とトルクの変換:モーターチェーンは、さまざまな速度で動力を伝達し、モーターと駆動部品間のトルクを変換するように設計されています。適切なスプロケットサイズとチェーン長を選択することで、回転速度とトルクをシステムの要件に合わせて調整できます。
3.柔軟性と適応性:モーターチェーンは柔軟性と適応性に優れているため、様々な向きや構成で使用できます。位置ずれ、不均一な負荷、方向転換にも対応できるため、複雑な機械やシステムに適しています。
4.メンテナンスと潤滑:モーターチェーンの確実な動作には、適切なメンテナンスと潤滑が不可欠です。定期的な点検、清掃、潤滑を行うことで、摩擦、摩耗、腐食を軽減し、チェーンの最適な性能と長寿命を確保できます。
Motor chains come in different sizes, designs, and materials to suit specific applications. Selecting the right chain for a particular system involves considering factors such as load capacity, speed, environment, and compatibility with other components. It is important to follow the manufacturer’s guidelines and industry standards to ensure safe and efficient operation.
