Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A journal bearing of a printing machine for supporting a shaft having a central axis in a bore of a frame, comprising a flanged bearing sleeve having a portion coaxially arranged to the shaft; and adjusting means for moving the flanged bearing sleeve relative to the frame so as to compensate for misalignments of the bore, said bore having a predetermined depth, said flanged bearing sleeve being formed with a projecting centering member integral with said portion of the sleeve and abutting said frame at the inner side thereof, said centering member having a width which is smaller than the predetermined depth of said bore so that two annular clearances are formed which are defined by the frame, the flanged bearing sleeve and the centering member.
Claim 2
Dependent Claim
126 words
A journal bearing of a printing machine for supporting a shaft having a central axis in a bore of a frame, comprising a flanged bearing sleeve having a portion coaxially arranged to the shaft; and adjusting means for moving the flanged bearing sleeve relative to the frame so as to compensate for misalignments of the bore, said bore having a predetermined depth, said flanged bearing sleeve being formed with a projecting centering member integral with said portion of the sleeve and abutting said frame at the inner side thereof, said centering member having a width which is smaller than the predetermined depth of said bore so that two annular clearances are formed which are defined by the frame, the flanged bearing sleeve and the centering member.
Claim 3
Dependent Claim
22 words
A journal bearing as defined in claim 1, wherein the flanged bearing sleeve is of L-shaped axial section and of deformable material.
Claim 4
Dependent Claim
21 words
A journal bearing as defined in claim 1, wherein the flanged bearing sleeve embraces a sliding bushing which supports the shaft.
Claim 5
Dependent Claim
56 words
A journal bearing as defined in claim 3, wherein the flanged bearing sleeve is provided with a plurality of grooves uniformly spaced around its periphery, said adjusting means including a plurality of wedges located in said grooves, the grooves being in engagement with respective wedges which are movable therein relative to the shaft and the bore.
Claim 6
Dependent Claim
30 words
A journal bearing as defined in claim 4, wherein the flanged bearing sleeve is provided with three grooves which are angularly offset relative to each other at angles of 120°.
Claim 7
Dependent Claim
32 words
A journal bearing as defined in claim 4, wherein each of said wedges is provided with an oblong hole, the wedges being movable normal to said axis along the respective oblong holes.
Claim 8
Dependent Claim
31 words
A journal bearing as defined in claim 6, wherein the flanged bearing sleeve is connected with the wedges and the frame in form-locking manner by means of a plurality of screws.
Claim 9
Dependent Claim
55 words
A journal bearing as defined in claim 1, wherein the frame bore has a predetermined depth, the centering member having a width which is smaller than the predetermined depth of the bore of the frame so as to obtain two annular clearances each defined by the frame, the flanged bearing sleeve and the centering member.
