Question

) Given: You have to use a series 02 deep grove ball bearing with a C10 rating of 30.7KN and a catalog life rating of 106 cycles. The inner ring rotates and the reliability is 90%. You want the bearing to last 4000hrs at 1200RPM. What is the Fo (desgin rating). Given: You have to use a standard series 02 deep groove ball bearing. Your design radial force is 650Lb and your design life is 25Khrs. The torque being transmitted is 1000 in-lb and the power is 14 hp. The inner ring is rotating and the reliability is 95%. Use the weibull parameters of Xo-02, (Theta-X0-4439 and b-1.483. The bearing is used for machenery with light impact. Solve the C10 rating and select a bearing. D) What is the bore What is the OD .If the static load is 300Lb is the bearing ok and why C) Given: Design loads of Fa = 500lb and Fr = 700th You are using a standard roller bearing with a C10 rating is 7900 lbs dynamic rating and Co -4450 Lbs static rating. The outer ring is stationary, the required Using the table below solve the equivelent radial load for all of the load cases. Then solve the C1O rating Fei reliability is 90% and the design RPM is 1200RPM. Solve the design life (hrs) d for a standard roller element bearing. Note use the total cycles for Lo L.Case , Khr Time, RPM af Fei Cycles af, fraction 675 1.1 1.25 3000 4000 1000 1200 2 789 1200 1.1 3.5 4.5 345135 What is the totat hrs of all of the load cases and what is the total cycles of all of the load cases.
