PROTECTIVE COVER OF JOINT OF EQUAL ANGULAR SPEED Russian patent published in 2011 - IPC F16D3/84 

FIELD: machine building.

SUBSTANCE: protective cover consists of corrugated part connected to mount portions of bigger and smaller diametres which are mounted and successively attached to case and shaft of joint by means of yokes. Each mount portion of the cover has two coaxially arranged semi-oval circular lugs. A vertex of one semi-oval circular lug is directed outward and contacts the yoke, while a vertex of another semi-oval circular lug is directed inward and contacts one of corresponding parts of the joint. In lengthwise axial section of the cover surface of external semi-oval circular lug is made in form of a semi-circle along length of external surface of the mount portion, while surface of internal semi-oval circular lug is made flat on a part of length along total length of internal semi-oval surface of the mounting portion. Diametre of the internal semi-oval circular lug does not exceed external diametre of a seat of a corresponding contact part of the joint.

EFFECT: increased pressure tightness of protective cover, raised reliability of attachment of protective cover to parts of joint at operation; increased service life.
