Plate-cylinder bearing for rotary printing machine, has outer bearing race, and gap allowing elastic expansion of bearing race radially outward from inner side to enable expansion of outer and inner bearing races in radial direction

摘要

#CMT# #/CMT# The bearing (1) has an outer bearing race (5) arranged in a hole (3) of a side frame (4), and an inner bearing race (7) rotatably supported against the outer bearing race. A gap (11) is provided between the outer race and the hole, and extends in an axial direction over a shifting region (A) arranged between the inner race and a third bearing race (8). The gap allows elastic expansion of the outer race radially outward from inner side to enable expansion of the bearing races (5, 7) in a radial direction free from exceeding a maximum allowable initial load in the shifting region. #CMT#USE : #/CMT# Plate-cylinder bearing for a rotary printing machine during machine tool manufacture. #CMT#ADVANTAGE : #/CMT# The gap extends in the axial direction over the shifting region arranged between the outer bearing race and the third bearing race, thus enabling compensation of internal and external loads and thermal expansion of the bearing without any risk for the bearing at any time point and without exceeding of the maximum allowable initial loads of the bearing races among each other at any time point. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic longitudinal sectional view of a plate-cylinder bearing.
