Abstract 1,098,912. Bearings; non-metallic springs. BORG-WARNER CORPORATION. April 15, 1965 [June 8, 1964], No. 16364/65. Headings F2A and F2S. In a bearing assembly a shaft is journalled in a bearing C housed in a resilient annular ring D itself supported in an annular retaining ring 25 in a fixed bracket A. In Fig. 1 rubber ring D comprises an annular body 40, projecting portions 46 having converging surfaces 44, 45 and ears 48, 49 joining the surfaces by neck portions. Grooves 27, 28 in retainer 25 accommodate portions of the ears. Axial displacement of the shaft causes the ears to rock in the grooves and to bend at the neck portion, greater radial load being taken by the folded ear than by the unfolded ear. Axial displacement is limited by co-operation of a surface (28b, Fig. 6, not shown) on the groove with a surface (54) on an ear. Angular displacement of the shaft axis causes rocking of those ears which are in the plane of the displacement, and twisting of the other ears.
A BEARING SUPPORT, FOR A SHAFT COMPRISING: BEARING MEANS ADAPTED TO ROTATABLY JOURNAL SAID SHAFT THEREIN, AN ANNULAR RETAINER SURROUNDING SAID BEARING MEANS IN RADIALLY SPACED RELATIONSHIP, A BRACKET FIXEDLY SUPPORTING SAID RETAINER, AND ANNULAR INSULATING MEANS DISPOSED BETWEEN SAID RETAINER AND BEARING MEANS EFFECTIVE TO MAINTAIN UNIFORM TRANSMISSIBILITY THEREBETWEEN WHILE ACCOMMODATING AXIAL AND ANGULAR DISPLACEMENT OF SAID BEARING MEANS RELATIVE TO SAID RETAINER, SAID INSULATING MEANS PARTICULARLY COMPRISING A PLURALITY OF FLEXIBLE EARS EXTENDED GENERALLY. RADIALLY, OUTWARDLY AND ARRANGED IN AXIALLY SPACED PAIRS, EACH PAIR OF EARS COOPERATING AS A SINGLE COLUMN OF RUBBER TO SUPPORT RADIAL LOADS BETWEEN SAID RETAINER AND BEARING MEANS, EACH PAIR OF EARS HAVING FREE ROCKING CONTACT WITH SAID RETAINER WHICH PERMITS EARS TO SHIFT CONTACT
