BEARING ASSEMBLY FOR ROCK CRUSHERS (VERSIONS) Russian patent published in 2017 - IPC F16C33/02 F16C33/10 B02C2/04 

FIELD: disintegrators and devices for crushing.

SUBSTANCE: invention generally relates to bearing assemblies and in particular to bearing assemblies intended for use in rock crushers. Bearing assembly (20) is mounted on rock crusher (22), including main housing (24), drive shaft (26), eccentric (28) and crushing head (30). Bearing assembly (20) includes first bearing ring (32) arranged around drive shaft (26) and on eccentric (28), second bearing ring (34), which is located adjacent to first ring (32) or on housing (24), or crushing head (30), and device (46, 48) to supply working fluid under pressure, at least on first ring (32) and second ring (34). At least one of rings (32, 34) includes closed recess for working liquid, intended for receiving and collection of working fluid under pressure. Recess wall inner outline for working fluid prevents working fluid radial supply inward from rings (32, 34), and recess wall outer outline for working fluid prevents working fluid radial supply outward from rings (32, 34). Recess receives working fluid through inlet hole for liquid supply, located at distance from recess wall inner outline. First ring (32) and second ring (34) are intended for hydrodynamic separation of each other before start-up. Bearing assembly (20) is intended for transmission of all loads produced by crushing head, directly through first ring (32) and second ring (34).

EFFECT: creation of bearing assembly, intended for use in rock crushers, allowing to reduce formation of heat during bearing operation and increasing bearings service life, as well as increase bearings load and simplify bearings maintenance, repair and replacement.
