The framework oil seal is mainly used in agricultural machinery. When the general working conditions of the oil seal are poor, the temperature difference between the environment is large, there are many dust, and the vibration of the machines and tools frequently makes the mechanical condition of the parts constantly changing, it is necessary to check, maintain and maintain it frequently.
If the shaft diameter and bearing are seriously worn; the oil seal rubber is aging or the spring fails, repair and replace the corresponding parts in time.
I. installation of framework oil seal:
During the installation of framework oil seal, if the surface roughness of the shaft diameter is low or there are defects such as rust spots, rust, burrs, etc., it is necessary to polish it with fine emery cloth or oilstone; apply clean oil or lubricating grease to the lip of the oil seal or the corresponding position of the shaft diameter. Apply sealant to the outer ring of the oil seal, wrap the keyway on the shaft with hard paper to avoid scratching the lip of the oil seal, and use special tools to rotate the oil seal inward and press it in. Do not smash it hard. In order to prevent the oil seal from deforming or breaking the spring, it must be removed and re installed in case of lip flanging, spring falling off and oil seal deflection. It should be noted that when the shaft diameter is not worn and the spring force of the oil seal spring is sufficient, do not tighten the inner spring without authorization.
II. Scope of application of framework oil seal:
Skeleton oil seal can be used in many occasions, especially in poor working conditions such as construction traveling machinery, crane, fire truck and mining machinery truck, which has good sealing performance and mechanical characteristics. It is the main component of shaft auxiliary seal. In the heavy load situation, the lip seal ring can be used by adding block or combining with the shaft seal series to make the sealing effect better. Lip seals have two geometry: single lip and double lip. It has a small friction resistance, a certain anti leakage ability and a strong resistance to impact peak pressure. Because of the self-lubricating oil cavity between the main and auxiliary lips, the friction resistance and creeping phenomenon are reduced. Due to the needs of different media, it can provide a variety of performance materials.
