Identical Timken deep groove ball bearings are used in a to support a solid steel rotating shaft with a constant 40 mm diameter. The housing bore diameter is 62 mm. The shaft carries a transverse load FB at the axial position shown, is subject to "moderate impact," and rotates at 950 rpm. There are no axial loads on the shaft. FB =? d=40mm 150 mm 250 mm The application requires a life of at least 2000 hours at a reliability of 96.5%. The bearings will be lubricated by clean, A B Noto S 4 D= 62 mm high quality grease, alignment is within limits, and operating temperatures are low. Use the middle of the recommended range for estimating KA. (a) Considering Timken's standard series of deep groove ball bearings (9300K, 9100K, 200K, 300K), specify the bearing number to be used for this application. (b) What is the allowable equivalent radial design load on the most heavily loaded bearing? (c) What is the maximum allowable value for FB? (d) What is the total frictional power loss for the bearings on this shaft (use SKF coefficient of friction estimates)? (e) Calculate the static factor of safety for bearing A. (f) What is the reliability of bearing C at the specified design life? 20 Points In this application the external shaft load is stationary. The housings are stationary. The outer ring needs to be "easily displaceable" relative to the housing. (g) Is the load on bearing A considered to be "light," "normal," or "heavy"? Justify your Answers (a) Bearing number (b) P. (kN) (c) FB,allow (kN) (d) Wloss, total (watts) answer. (e) no,A (f) Rc at 2000 hrs (%) (h) What is the tolerance class recommended for use with the shaft diameter? (g) Load severity (h) Shaft tolerance class (i) What are the limit dimensions for the shaft diameter and bearing bore? (i) dshaft,max (mm) (j) What is the allowance for the shaft/bearing bore fit? dshaft.min (mm) dbore,max(mm) (k) What type of fit is this (clearance, transition, interference)? dbore,min (mm) (j) Shaft/bore allow. (mm) (1) What is the tolerance class recommended for use with the housing bore diameter? (k) Shaft/bore fit type (1) Housing tolerance class (m) What are the limit dimensions for the housing diameter and bearing outer ring OD? (n) What is the allowance for the outer ring/housing fit? (o) What type of fit is this (clearance, transition, interference)? 20 Points (m) Dhous,max (mm) Dhous, min (mm) Dout ring.max (mm) dout ring,min (mm) (n) Bearing OD/hous. bore allow.
