Examine the design shown in the figure below of an overhung chain idler sprocket and answer the following questions: (a) name the type of bearing and write names of its three main components? (b) name three type of loads applicable in bearing design? (c) how is thrust in each direction carried by one and only one bearing? (d) instead of a snap ring to hold the chain sprocket in place, how could you tighten the sprocket onto the shaft in a controlled fashion? (e) grooves for snap rings introduce stress concentrations. Why is this not a concern for the shaft here? (f) what is a plain surface bearing? Clamping supports Rotating shaft Chain sprocket For the design similar to above figure, based on a bore diameter of 55 mm, a radial load of 1,742 lb and a thrust load of 265 lb, select a suitable radial contact bearing for 8,000 hr of use at 100 rpm with 96% reliability under light to moderate impact loading.
