摘要

#CMT# #/CMT# The device has a lower hinge plate (4) whose rolling unit is equipped with a radial bearing unit (12) to support radial loads and an axial bearing unit (14) to support axial loads. The radial and axial bearing units authorize coaxiality angular defects of a fixed hinge plate (6) with respect to a movable hinge part (8) of the lower hinge plate. A rolling unit of an upper hinge plate is equipped with another radial bearing unit to support the radial loads. A lower fulcrum pin (10) of the lower hinge plate is placed in a lower hub (8'). #CMT# : #/CMT# An independent claim is also included for a heavy door, comprising a door leaf. #CMT#USE : #/CMT# Oscillating hinge device for a heavy door permitting access to a closed space of a hostile environment i.e. nuclear thermal power station (all claimed). #CMT#ADVANTAGE : #/CMT# The device prevents all parasitic frictions of axes of the hinge plates while opening or closing of the door leaf of the heavy door, and reduces manufacturing cost of the heavy door. The device prevents axial displacement of the lower fulcrum pin in an effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross sectional view of a lower hinge plate. 4 : Lower hinge plate 6 : Fixed hinge plate 8 : Movable hinge part 8' : Lower hub 10 : Lower fulcrum pin 12 : Radial bearing unit 14 : Axial bearing unit.
