Structural analysis of TC oil seals
TC oil seals usually consist of three parts: sealing lip, reinforcement skeleton and rubber body. The sealing lip is the core part of the oil seal. It is in direct contact with the rotating shaft and prevents the leakage of fluids such as lubricating oil by closely fitting the shaft surface. The design of the sealing lip is extremely sophisticated, and its shape and material selection have been strictly considered to ensure that a good sealing effect can be maintained under different working conditions. The reinforcement skeleton is generally made of metal to provide the necessary strength and stability for the oil seal, so that it can withstand certain pressure and mechanical vibration and is not easy to deform. The rubber body wraps the skeleton and sealing lip, which plays a role in buffering and isolating external impurities, while giving the oil seal good flexibility to adapt to slight eccentricity and vibration of the shaft.
Working Principle Revealed
When the shaft in the mechanical device starts to rotate, the sealing lip of the TC oil seal fits tightly to the surface of the shaft under the combined effect of its own elasticity and lubricating oil film. The lubricating oil forms an extremely thin oil film between the sealing lip and the shaft. This oil film not only plays a lubricating role, reducing the friction and wear between the sealing lip and the shaft, but also uses the surface tension of the liquid to form an effective sealing barrier to prevent the leakage of internal lubricating oil. At the same time, the rubber body and reinforced skeleton of the oil seal jointly resist external pressure and impurities to ensure that the oil seal works stably in complex environments.
