Gearbox input, output shaft end sealing
Thread Content
Let’s discuss how to achieve absolute sealing at the input and output shaft ends of high-speed gearboxes Prevent gas from entering the gear box.
What does absolute sealing mean? Do you mean a gas under pressure?
Zero permeation of external gases, and zero leakage of gases inside the gearbox
Can this oil seal meet the requirements? I’m putting a top post for you; I’ll learn* it too
Nitrogen protection is generally used (in flammable and explosive environments)
An absolute seal is necessary. It seems that a regular shaft seal combined with an inert gas isn’t sufficient to meet your requirements; I think what you need is more advanced and complex technology
This requires multiple sealing methods, such as a combination of mechanical seals and labyrinth seals as well as floating ring seals; achieving complete zero leakage is unlikely
There is no absolute waste heat seal; mechanical seals, dry gas seals, floating ring seals, etc., can be used.
My rotation speed is quite high, over 10,000 revolutions per minute. If a combined seal is to be used, which type would be suitable?
Leakage is relative; I don’t feel it
