In a gear set, a 36-tooth spur pinion drives a 60-tooth spur gear. The teeth of these gear are cast iron profile. The diametral pitch is 6-teeth/in, the face width si 0.5 inches, and the pressure angle is 20 degrees. Assume that the pinion transmits 10 hp at a speed of 2000 rpm. Find the pitch diameters of the gears. Find the pitch line velocity in ft/min Find the velocity factor Ky Find the tangential load in lbf Find the contact stress in kpsi, assuming CP=1960 psi.
73 ll 6 O ... The pitch circle radius multiplied by the cosine of the pressure angle. Q3:- The increase of the contact ratio is desirable in gearing design because of:- * All of these The number of teeth will be increased in the engagement region More strength and more gear life will be achieved Smoother and faster motion None of these Q4:- To get best gearing design, it requires to:- * Increase sliding None of these Decrease sliding
