Simple bearing friction force calculation
Simple bearing friction force calculation
(OP)
Hi everybody,
could anybody help me to remember hot to calculate the friction force value in a simple bearing system (a spindle in a bearing)?

RE: Simple bearing friction force calculation
Excerpt from SKF Interactive bearing catalog for rolling element bearings:
"Under certain conditions (bearing load P » 0,1 C, good lubrication, normal operating conditions) the frictional moment can be calculated with sufficient accuracy using a constant coefficient of friction µ from the following equation
M = 0,5 µ F d
where
M = frictional moment, Nmm
µ = coefficient of friction for bearing (Table 1)
F = bearing load, N
d = bearing bore diameter, mm"
=============
Table 1 gives mu depending on bearing type. For example deep groove bearings without seals, mu=0.0015

RE: Simple bearing friction force calculation
I wonder how to keep on with the above analyses, to the calculation of medium/big size bearing lubrification requirements, i mean to estimate the generated heat as function of F and bearing type, can we have the clearance about the essencial aspects ? Thank you?
