Title:
ROTATING MEMBER SUPPORT STRUCTURE OF FIXING DEVICE AND ROLLING BEARING USED FOR THE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2008/001831
Kind Code:
A1
Abstract:
Provided are a rotating member support structure for a fixing device and a rolling
bearing used for the structure. The structure rotatably supports shaft parts
of a rotating member by bearings that are fitted on the shaft parts by clearance
fit, is capable of preventing creep and abnormal noise from occurring for a long
period, and, as required, renders separate grounding means unnecessary. The
structure has the shaft parts (9a) of the rotating member of the fixing device
and also has the bearings (1) fitted on the shaft parts (9a) by clearance fit to
rotatably support the shaft parts (9a). Coating having low-friction sliding
properties is formed on at least either the shaft parts (9a) or the bearings (1),
on at least portions coming into contact with the other members by fitting. The
thickness of the coating is 2 to 10 μm, and the coefficient of dynamic friction
at the portions where the bearings and the shaft parts are in contact with each
other and where the coating is formed is 0.2 or less.
