4. A bearing is subjected to a radial force of 8kN and a thrust force of 3 kN. The values of X and Y factors are 0.56 and 1.5 respectively. The shaft rotates at 1200 RPM. The diameter of the shaft is 75mm and Bearing no. 6315 (C= 112000N) is selected for this application. Estimate the life of this bearing with 90% reliability.
A gearset has a module of 5 mm, a 20 degree pressure angle, and a 24-tooth cast iron spur pinion driving a 48-tooth cast-iron gear. The pinion is to rotate at 500 rev/min. The objective is to calculate the power in kwatt that can be transmitted by the gearset.. In this case, the cast iron, cast profile gears and the velocity factor must be calculated from the Barth equation. The bending stress is limited to 50 MPa and the facewidth is 60 mm. The velocity factor is considered to be significant and must be used in stress calculations. Calculate the power in kwatt the gearset can transmit using the Lewis bending equation. Note: in this case the stress MUST be modified by the velocity factor, Kv.
