Automobile electromagnetic clutch bearingAir conditioning
electromagnetic clutch bearings are sealed double row angular
contact ball bearings, which special designed in seal structure,
raceway groove and steel balls with main parameters, selection of
raw materials, and the heat treatment, especially the selection of
the grease, etc. These pertinently satisfied specific requirements
of bearings, as high operating ambient temperature, high sealing
requirements, big axial force, and working surface easy to produce
white flaking that affected by magnetic field, etc.APPLICATION
FEATURES1. Outer ring running;2. Ambient temperature above 130 ºC,
and the actual working temperature exceeds 160 ºC;3.
Surrounding of bearings filled with water vapor, dust;4. Use in
high-temperature and alpine region;5. Affected by magnetic field
acts, prone to have white flaking of groove;6. In the pull in and
separation process of clutch, bearing under an axial
force exceeds 300N's;7. Operate of belt transmission; the
rotation speed of bearings change frequentlyduring operation; force
direction changes with belt swing; magnitude of loadchanges
frequently -- under a greater impact of variable speed and
variable load.PERFORMANCE1. High requirement of sealing
durability:Not allow water vapor, dust leaking into the bearing for
a long time;2. High requirement of high-speed operation
performance;3. Excellent thermal stability at -40 ºC ~ 180 ºC;4.
Starting torque:select medium contact seals;5. Long service life:in
accordance with the requirements of electromagneticclutch bearings,
testing life required more than 500h.ADVANTAGEThe material
selection of bearing components:1. Rings manufactured by
high-purity specialty quality bearing steel;2. Steel balls are from
famous brand manufactures, that effectively guaranteematerials and
processing accuracy;3. Using glass fiber reinforced nylon cages;4.
Sealed with high quality acrylic rubber;5. Using synthetic oil
(base oil) + Polyurea (thickening
agent)Grease. DESIGN STRUCTURES1. Sealed with tri-lips
medium contact structure-- having a high sealing performance, and
suitable for high-speed operation;2. Using engineering plastic
cages with oil reservoir structured
--
effectively increase the lubrication capability of bearings;3.
Optimize the groove curvature of outer ring and the raceway of
inner ring-- suitable for high-speed and axial movement; 4.
Raceway machined by diamond wheel machining, that effectively
controlled dimension difference and curvature difference of
raceway.
