The bucket elevator service life depends on the drums and shafts.However,in the production practice,we need to adopt some other measures to ensure the shaft service life,the measures are as below:
1.The failure mechanism should be fully taken into accounted for the Selection of design and calculation and fatigue design can be adopted. Try to reduce stress concentration.
2.Put forward reasonable technical requirements and technical conditions of the shaft, and ensure to strictly implement these requirements and conditions.
3.Make sure the failure mechanism of the spindle is fatigue damage.
4.Spindle for inspection and sample routine mechanical performance test to ensure that the spindle performance is reliable.
