Consider a single row ball bearing acted upon by a time-varying radial load F = (100 - 100 cos(2πN)) kN, where N represents the fraction of revolutions. Determine the mean cubic load F. Answer Choices: a. 130 kN b. 136 kN c. 120 kN d. 122 kN
Added by Juan D.
Step 1
This is done by integrating the load function over one revolution and dividing by the total number of revolutions, which is 1 in this case. The integral of F from 0 to 1 is: ∫ from 0 to 1 (100 - 100 cos(2πN)) dN = [100N - (100/(2π))sin(2πN)] from 0 to Show more…

A shaft rotating at a constant speed is subjected to a variable load. The bearings supporting the shaft are subjected to a stationary equivalent radial load of 3 kN for 10 percent of the time, 2 kN for 20 percent of the time, 1 kN for 30 percent of the time, and no load for the remaining time of the cycle. If the total life expected for the bearing is 20 × 10^6 revolutions at 95 percent reliability, calculate the dynamic load rating of the ball bearing.

An 02-series ball bearing is to be selected to carry a radial load of 8 kN and a thrust load of 4 kN. The desired life LD is to be 5000 h with an inner-ring rotation rate of 900 rev/min. What is the basic load rating that should be used in selecting a bearing for a reliability goal of 0.90?
