shaft seal

A gearbox oil seal is a component of a transmission system that helps to keep the transmission fluid inside the gearbox. It is a rubber seal that fits around the outside edge of the gearbox, preventing the fluid from leaking out and contaminating the surrounding area. It is important to replace the seal when necessary, as a damaged or worn seal can lead to serious transmission problems.

The shaft seal is a sealing element which seals the rotating shaft, of a centrifugal pump where it passes through the non-rotating pump casing reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.During rotation, the shaft drags a thin film of lubricant past the wavy edge and into the seal-to-shaft interface, causing the seal to hydroplane. This hydroplaning action prevents the direct contact, dry rubbing wear, and high friction associated with conventional non-hydrodynamic seals.

The crank seal is an important part of your engine. It is usually made of metal and rubber. Its purpose is to seal the end of the crankshaft. The crank seal keeps the oil in, while keeping dirt and debris out. If the seal fails, it will result in a leak.The crankshaft is supported by main bearings, which receive oil to lubricate the crankshaft. The rear main seal prevents oil from getting out of the crankcase and into the transmission housing. The gasket is made of rubber and can easily deteriorate, leading to oil leaks.

The crank seal is an important part of your engine. It is usually made of metal and rubber. Its purpose is to seal the end of the crankshaft. The crank seal keeps the oil in, while keeping dirt and debris out. The experienced Field Service Engineers at Lycoming indicate that a leaking crankshaft oil seal is frequently caused by a restricted breather or an oil-slinger clearance that is too tight. The leak might also be caused by a propeller defect which places an abnormal side load on the crankshaft oil seal.
