The optimal parameters and comparative characteristics of gasdynamic thrust bearings and dry seals with spiral grooves on one and both walls of the lubricating layer

摘要

Algorithms for calculating gas dynamic bearings and dry seals with spiral grooves on one and both working surfaces are constructed. It is proved that the model with a two-sided identical profile in the form of spiral grooves possesses the best characteristics among all devices based on the use of a relative sliding velocity.
