ANALYSIS of WORK of BILATERAL PERSISTENT  HYDROSTATICAL BEARING

 

V.I. Nazin

 

The necessity of application of hydrostatical slidewaies as supports rotors of turbo-engines is Rotined. The different types of the gidrostati-cheskikh bearings are analysed and for the chosen type of bearings the chart of setting of rotor is offered on these bearings. The mathematical model of the bilateral persistent hydrostatical bearing, allowing to expect his basic descriptions, is developed. Executing the calculation of the persistent hydrostatical bearing and the analysis of results of calculation is conducted. It is rotined that necessary bearing strength of bearing can be provided with the selection of the proper pressure of feed of greasing and size of gap in bearing.

Key words: hydrostatical bearing, turbo-engine, mathematical model, bearing ability pressure of feed, gap.
