35、LOAD RATINGS AND RATING LIFEX1.1 Basic Dynamic Load RatingX1.1.1 The Basic Dynamic Load Rating is that constantstationary load which a group of apparently identical bearingswith stationary outer rings (cups) can endure for a rating life of90 million revolutions of the inner ring (cone). The basicdyn
36、amic load ratings listed herein are based on a rated life of90 million revolutions or 3000 h at 500 revolutions per min.X1.1.2 To compare the load ratings in this specification withother load ratings whose basis for ratings are other than 90million revolution or 3000 h at 500 rpm, use the followingf
37、ormula:C 5 Other Bearing Load Rating 3 R1/500!1/f3 H1/3000!1/f(X1.1)where:R1= rotational speed (in rpm) at which other bearing israted,H1= hours at which other bearing is rated, andf = other bearing fatigue factor.X1.2 Rating Life (Hours)X1.2.1 The rating life is the number of hours at someconstant
38、speed of the inner ring (cone) that 90 % of a group ofapparently identical bearings will complete or exceed beforefirst evidence of fatigue develops. The magnitude of the ratedlife in hours is found from the following:L10 5 1.5 3 106!/R 3 C/P!10/3h (X1.2)where:C = basic dynamic load rating,P = equiv
39、alent load (combined radial and thrust load) kN,andR = rotational speed, in revolutions per minute.X1.2.2 The average life is approximately four times therated life.TABLE 7 Outer Ring (Cup) Outside Diameter Tolerance (Class B)Outer Ring (Cup) O.D.
