FREE TURBINE OF GAS PUMPING SET DRIVE

摘要

mechanical engineering; drives. SUBSTANCE: free turbine has antifriction bearing housings with lubrication channels installed slacklessly in rotor support housing and sealed by rubber rings. Housing of front antifriction bearing is installed in support housing with radial clearance of 0.1-0.2 mm. It is provided with lubrication channels uniformly spaced over circumference and radial dowel slacklessly installed in support housing and installed with clearance, not less than radial clearance between housing and bearing, in antifriction bearing housing. EFFECT: improved reliability and increased longevity of turbine owing to reduction of vibration level. 2 dwg
