COMBINED SUPPORT Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: combined support has housing which receives rolling bearing and hydrodynamic bearing. The hydrodynamic bearing is mounted eccentrically with respect to the axis of the rolling bearing. The inner race of the rolling bearing receives bushing made of an antifriction material. The bushing receives the shaft with clearance h₁. This allows the surface of the bushing to be used as an additional hydrodynamic bearing. The shaft of the hydrodynamic bearing is mounted with a spaced relation h₂, which is greater than h₁ in the bushing. This excludes the engagement of the shaft with the surface of the hydrodynamic bearing.

EFFECT: enhanced reliability and prolonged service life.
