STEADY-THRUST SLIDING BEARING WORKING ON LOW-VISCOSITY LIQUID Russian patent published in 2002 - IPC

FIELD: mechanical engineering; petrochemical industry; refrigerating engineering where compressor units are used. SUBSTANCE: races of sliding bearing are provided with longitudinal slots; they are provided with additional outer taper surfaces which are engageable with taper surfaces of body and inner working cylindrical surfaces periodically embracing shaft bush. Bearing is also provided with two inserts taking up radial load at steady operation of unit. Parts of main bearing of proposed steady-thrust bearing work in steady liquid friction mode at presence of radial and axial loads, thus improving technological and hydrodynamic characteristics of unit. EFFECT: reduced friction losses; reduced wear; enhanced durability. 1 dwg
