What are the most common use of skeleton oil seals?

The skeleton oil seal should be made by the professional master. The excellent performance always appears in many different scenes and is a very stable fastener. The knowledge of the use of the skeleton oil seal needs to be understood by the purchaser, and the knowledge of the fastener will be well known. So, what are the common usage scenarios?

Skeleton oil seal use

The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal leaks; if the thickness is too small, dry friction may occur, causing oil seal and shaft wear; if there is no oil film between the seal lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis of the shaft. If it is not vertical, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing lips. abrasion. During operation, the lubricant in the casing slightly exudes a little to achieve a state in which an oil film is formed at the sealing surface.

The purpose of the skeleton oil seal is generally to isolate the parts of the transmission component that need to be lubricated from the output parts, so as not to let the lubricating oil leak, and is usually used for rotating the shaft, which is a rotating shaft lip seal. The skeleton acts like a reinforcing bar inside the concrete member, which acts to strengthen and maintain the shape and tension of the oil seal. According to the skeleton type, it can be divided into inner skeleton oil seal, outer skeleton oil seal, and inner and outer skeleton oil seal. The skeleton oil seal is made of high quality nitrile rubber and steel plate, with stable quality and long service life. Widely used in automobiles, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels and other parts.

1. Prevent mud, dust, moisture and other intrusion into the bearing from the outside;

2. Limit the leakage of lubricating oil in the bearing. The requirements for oil seals are that the dimensions (inner diameter, outer diameter and thickness) should be in accordance with the regulations; the proper elasticity is required, the shaft can be properly clamped and sealed, and the heat resistance, wear resistance, strength, and medium resistance are required. Oil or water, etc.), long service life.

It can be seen that the full use of the skeleton oil seal can make the mechanical performance in the manufacturing industry more stable. Consulting with the merchants is the process of purchasing and preventing mistakes during use. Therefore, everyone should master the basic product knowledge, and the flexible use of the purchased fasteners, otherwise there will be trouble in the application.
