Abstract
Abstract A cylindrical roller bearing of the kind having a separate abutment ring at the inner bearing ring is used to provide intentional compensation of axial play between a journalled shaft and the surrounding bearing casing in a bearing combination which comprises at least one conical roller bearing in addition to said cylindrical roller bearing. The axial position abutment of the inner ring of the cylindrical roller bearing on the shaft to be journalled is located with an axial spacing from the position abutment surface of the outer ring of said bearing in the casing, which spacing corresponds to the maximum expected axial play which is to be compensated for, and spacing means of required thickness are then mounted between the abutment ring and a locking member on the shaft.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
The method of rotatably journalling a shaft comprising the steps of assembling a shaft to be journalled in a combination bearing consisting of at least one conical roller bearing and a cylindrical roller bearing positioned in axially spaced relation to one another in a bearing casing, each of said bearings having an outer ring which is mounted in said bearing casing and an inner ring which engages the outer periphery of said shaft, said cylindrical roller bearing being of the type having a separate abutment ring adjacent the inner bearing ring of said cylindrical roller bearing which is in engagement with and axially displaceable relative to the outer surface of said shaft, adjusting the axial position of said separate abutment ring of said cylindrical roller bearing to axially space the abutment position of said inner ring of said roller bearing on said shaft from the abutment position of said outer ring of said roller bearing in said casing by a maximum expected axial play of said shaft relative to said casing which is to be compensated for, and then inserting spacing means between said abutment ring and a locking member on said shaft.
Claim 2
Independent Claim

The method of rotatably journalling a shaft comprising the steps of assembling a shaft to be journalled in a combination bearing consisting of at least one conical roller bearing and a cylindrical roller bearing positioned in axially spaced relation to one another in a bearing casing, each of said bearings having an outer ring which is mounted in said bearing casing and an inner ring which engages the outer periphery of said shaft, said cylindrical roller bearing being of the type having a separate abutment ring adjacent the inner bearing ring of said cylindrical roller bearing which is in engagement with and axially displaceable relative to the outer surface of said shaft, adjusting the axial position of said separate abutment ring of said cylindrical roller bearing to axially space the abutment position of said inner ring of said roller bearing on said shaft from the abutment position of said outer ring of said roller bearing in said casing by a maximum expected axial play of said shaft relative to said casing which is to be compensated for, and then inserting spacing means between said abutment ring and a locking member on said shaft.
Claim 3
Dependent Claim
35 words
The method of claim 1 wherein said inserting step comprises placing annular shim means of preselected thickness between said abutment ring and an annular locking ring that is fitted into a groove on said shaft.
