5 An industrial dough mixer is to be driven off a 45 KW motor running at 520 r/min via a two-gear speed reduction mesh with a pressure angle of 20 The dough mixer is required to run at 130 r/min and the gear on the motor has a pitch circle diameter of 60 mm. The effective overhang on the dough mixer drive is 50 mm. Use a factor of safety of 3 and design according to the maximum shear stress theory of failure a specially manufactured hollow shaft for the drive. The shaft should be from BS970:817M40 steel (Q&T) with a diameter ratio of 3 5 5 An industrial dough mixer is to be driven off a 45 KW motor running at 520 r/min via a two-gear speed reduction mesh with a pressure angle of 20 The dough mixer is required to run at 130 r/min and the gear on the motor has a pitch circle diameter of 60 mm.
