CLUTCH Russian patent published in 2004 - IPC

FIELD: machine engineering, namely drive systems of heavy-duty machines such as rolling mills, turbines, propellers of marine ships and others.

SUBSTANCE: clutch includes toothed sleeves with outer toothed band and toothed yokes with inner toothed band. Toothed yokes are engaged with toothed sleeves. Yokes are provided at one side with flanges mutually joined by means of bolts; at other side sealing lids are secured to yokes. Novelty is arrangement of closed hollow ring-like inserts in annular cavities between toothed yokes and toothed sleeves; said inserts have outer cylindrical surface and inner cone surface in the form of truncated cone whose large base is turned to toothed engagement and small base is turned to parting plane. Seals are placed at side of parting plane between end portions of outer and inner surfaces of inserts, inner surfaces of yoke and outer surfaces of sleeves. Inserts have radial through ducts arranged opposite relative to yoke openings for supplying lubricant. Said inserts are fixed against cranking by means of radial pins arranged in yokes. Sealing lids are fixed against cranking by means of lengthwise dowels fastened on them and arranged in grooves of end flanges of yokes to which said lids are secured.

EFFECT: increased useful life period of clutch, reduced consumption of lubricant.
