BEARING ASSEMBLY OF ECCENTRIC SHAFT OF CRANK HOT FORGING PRESS Russian patent published in 2003 - IPC

FIELD: machine engineering, namely forging presses such as crank hot forging presses. SUBSTANCE: bearing assembly of eccentric shaft of crank hot forging press includes sleeves mounted on ends of eccentric shaft. Said sleeves are rigidly joined to housing of press; slit type sealings are arranged in their end cavities. Sleeve arranged at side of gear wheel is in the form of hollow stepped cantilever. The last is provided with annular accumulation reservoir whose one end is joined with cantilever; other side of reservoir is in the form of sealing member. In combination with respective annular turnings of gear wheel boss, sealing member forms slit type sealing. Accumulation reservoir through pipeline is connected with hydraulic station of system for collecting, filtering and supplying lubricant to system for open liquid-circulation type lubricating hot forging press. Such structure provides open liquid-circulation system for lubricating sliding bearings of eccentric shaft, rolling bearings of gear wheel, for accumulating and supplying lubricant to hydraulic station. EFFECT: lowered maintenance costs, increased useful life period, enhanced accuracy rank of forgings. 2 cl, 2 dwg
