The diagram below shows a shaft with spur gear (B), bevel gear(D), and two supporting bearings (A and C). All dimensions are in millimeters and all shoulder fillets (at points where diameter changes) have a radius of . The pressure angle for the spur gear at B is . The pressure angle for the bevel gear at D is and the bevel angle is . Note that the shaft is designed so that only bearing A takes thrust. The shaft is made of steel with . All the critical surfaces are ground. The shaft rotates at . A motor with a power of is connected at the bevel gear through another bevel gear. This drives the shaft. A load is connected through another spur gear at the output spur gear at B. The standard deviation on the power is . (a) Determine the forces acting on the gears. Recall that for a spur gear, the relation between the tangential component of the force and the radial component of the force and the pressure angle is given by . For this bevel gear, the axial (thrust) component of the force on…
