Chinese skeleton oil seal is a typical representative of oil seal. Generally speaking, the oil seal under the high-efficiency china oil seal design refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated from the working parts in the transmission part to prevent the leakage of lubricating oil. The skeleton is like a steel bar in the concrete member, which acts as a reinforcement and maintains the shape and tension of the oil seal.

Chinese skeleton oil seal structure consists of three parts: oil seal, reinforced skeleton, and self-tightening spring. The sealing body is divided into bottom, waist frame oil seal, cutting edge, and sealing lip according to different parts. Generally, in the free state, the inner diameter of the skeleton is smaller than the shaft diameter, which has a certain “excess profile”. Therefore, when the oil is sealed into the oil seal and the shaft, the pressure of the oil seal vane and the contraction force of the self-tightening coil spring can produce a certain radial tightening force on the shaft. After running for a period of time, the pressure will drop rapidly or even disappear. Therefore, the spring can compensate the oil volume at any time.

Under the action of the Chinese skeleton oil seal, the rigidity of the oil film is just enough to make the oil film and the air contact end form a crescent surface to prevent the leakage of the working medium, so as to achieve the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the sealing cover, if it is too large, the oil seal will leak oil; if the thickness is too small, it may cause dry friction, which may cause damage to the oil seal and the shaft. Therefore, some oil must be applied to the sealing ring during installation, the skeleton oil seal must be vertical, and the axis line must be vertical. damage. During operation, the lubricant in the casing seeps out slightly to achieve the most ideal state of forming an oil film on the end cap.

The function of the Chinese skeleton oil seal is generally to isolate the parts that need to be lubricated from the contributing parts in the transmission parts so that the lubricating oil will not leak. It is usually used for rotary axes. It is a rotary shaft lip seal. The skeleton is like a steel bar in a concrete member, acting as a reinforcement to keep the oil seal in shape and tension. Internal and external oil seals. The skeleton oil seal is made of high-quality bonded rubber and steel plate, with stable quality and long service life.

Materials used

Typically Chinese skeleton oil seals consist of a metal housing and a flexible sealing element, usually made of a high-performance elastomeric material such as nitrile rubber, fluorocarbon or silicone. Metal housings are typically made of steel or other durable materials that can withstand high temperatures and pressures. Metal housings can also be coated or plated for increased corrosion resistance.

Design Features

A variety of design features are available to provide a reliable and effective seal. Flexible sealing elements are designed to conform to the shape of the rotating shaft or surface to provide a tight seal. Metal housings can also include additional features such as dust lips or auxiliary sealing lips to provide additional contaminant protection and improve sealing performance. Simmerring oil seal designs can also be customized to fit specific applications, such as in pumps or gearboxes.

Applications

Applications are wide ranging and include pumps, gearboxes and other rotating equipment. They are typically used in industrial applications where fluid leakage in rotating applications needs to be prevented. Simmerring oil seals are also used in automotive applications, such as wheel bearings and axles.

Performance Specifications

For Chinese skeleton oil seals are designed to withstand temperatures of -40°C to 200°C or higher, depending on the specific application. They can withstand pressures of up to 10,000 PSI or higher, depending on the application. Sealing elements are designed to provide low friction operation and long service life, even at high temperatures. Simmerring oil seals are also designed to resist chemical and oil degradation, ensuring long-lasting performance.

Installation and Maintenance

Installation should be performed using proper tools and techniques to ensure proper fit and seal. Improper installation can lead to premature seal failure, which can result in equipment damage. Regular maintenance is recommended to inspect seals for wear or damage and replace as needed. Proper lubrication is also important to ensure proper operation and prevent premature seal failure.
