A shaft with a helical gear wheel is bedded as in the figure. The forces of the gear wheel are F, 4 kN, F-10 kN and F, - 5KN, and the gear rolling circle diameter is d-100 mm. Since b-80 mm, c 100 mm, C-66.3 kN and C-405 kN for bearings, check if the life for B bearing is 5000 hours if the shaft rotates at n= 850 rpm. Note: The axial force is compensated by the B bearing.
Expert Answer
To check the life of the B bearing, we need to calculate the equivalent dynamic load on the bearing and compare it with the dynamic load rating of the bearing. The equivalent dynamic load on the bearing can be calculated using the following equation...
