オイルシールは一般的なシールのクセです。 簡単に言うと潤滑油のシールです。 油を封じるために使われる機械要素です（油は伝達系の中で最も一般的な液体であり、一般的な液体の意味も含みます）。 トランスミッション部分で潤滑が必要な部品を寄与部品から隔離し、潤滑油が漏れないようにします。 静的シールと動的シール（一般に往復運動）は、オイルシールと呼ばれるシール部分を使用します。

In mechanical engineering, oil seal is a common and indispensable sealing device. It undertakes the key task of sealing lubricating oil. In short, oil seals are used to seal mechanical components in liquids. This covers the most common liquid substances in transmission systems and also applies to the sealing needs of various liquid substances. The main function of the oil seal is to isolate the mechanical parts that need lubrication from the external environment to prevent lubricating oil from leaking.

Static and dynamic seals

Oil seals can generally be divided into two main types: static seals and dynamic seals. Both seal types play key roles in different machinery applications.

• Static Seals: Static seals are used on relatively stationary mechanical parts where no significant mechanical movement is involved. They are designed to ensure that lubricant oil does not leak from the mechanical system while blocking the entry of external impurities and contaminants. Static seals usually use elastic materials such as rubber to ensure reliable sealing.
• Dynamic Seals: Dynamic seals are used where lubricant is required to pass through mechanical parts, which often involve reciprocating or rotating motion. The design of dynamic seals needs to be more complex to ensure that sealing performance is maintained even under high-speed rotation or frequent movement. These seals often include additional structures, such as springs or sealing tips, to accommodate the requirements of the moving parts.

Application areas

Oil seals play a key role in a variety of mechanical systems and industrial applications. Here are some common application areas:

• Automobile industry: In automobile engines, oil seals are used to seal crankshafts, camshafts and other rotating parts to ensure the circulation of engine oil and the lubrication of mechanical parts.
• Industrial equipment: Oil seals are used in various industrial equipment such as pumps, compressors, fans and hydraulic systems to ensure their sealing performance and stable operation.
• Agricultural machinery: Agricultural equipment, such as tractors and harvesters, also use oil seals to maintain lubrication and sealing performance in various agricultural environments.

In general, the oil seal is an indispensable guardian of mechanical lubrication. They protect mechanical equipment from the threat of leakage and contamination by effectively sealing lubricating oil, ensuring continuous and efficient operation of equipment, extending life and reducing maintenance costs. They are indispensable components in the modern engineering field.
