UPPER ROLLER FOR PULL-OUT MECHANISM Russian patent published in 2015 - IPC D01H5/74 

FIELD: machine building.

SUBSTANCE: present invention relates to an upper roller of a pull-out mechanism. The upper roller (1, 1') for a pull-out mechanism includes the middle part of an axis (2, 2'), as well as two bearings of a journal (3) with shafts (4) located at the opposite ends of the middle axis part (2, 2'), and at least one rolling bearing providing for the support of an outer race (7, 7') is set at every free end of the above in any case. The middle axis part (2, 2') matches certain different division and/or shape of the seat of carrying and loading brackets, holes are provided on both sides of the middle axis part (2, 2') to set the shafts of the bearings (4), the holes (5) on both sides to press in the shaft of the bearing (4) are always of the same depth (B) for shafts of the bearings (4) always having the same length and the same diameter. All devices required for support are mounted on the bearing (4) shafts so that when assembling the upper roller (1) the middle axis part (2, 2') can be chosen according to different divisions and/or shapes of the seats of carrying and loading brackets regardless of the used bearing shafts (4) with rolling bearings (6) and the outer race (7, 7').

EFFECT: present invention allows for the simplification of the upper roller for a pull-out mechanism so that its manufacturing and assembly can be standardized and automated.
