Question
In a bevel gear the power input is on the AB axis, which transmits 10 HP rotating at 600 rpm in a negative direction on its axis. The sprocket of 18 dts at 20 degree of involute drives a wheel of 54 dts. For a reliability of 90%, a service life of at least 10,000 hours, an "O" mounting (the thrust load of the gear is supported on the bearing A) of the bearings and taking into account the previous results of this same exercise To identify the bearing that fully supports the thrust load. For static failure Determines for the axis AB: The location of the critical position Maximum axial and shear stress in the critical position The main efforts for the critical point of the critical position The value of the yield stress at the critical point, at a safety factor of 2, using the Tresca MSS criterion Selection of at least 2 materials that can be used to make the arrow. For dynamic failure Determines for the axis AB The material to be used to ensure a low notch sensitivity, The axial stress to which the critical section is subjected, The design safety factor of the critical section, using the dynamic criterion of material and manufacturing, What must be modified to obtain 2.5 lessthanorequalto N lessthanorequalto 3.5 How do the results change if the criterion of stress concentrators is used?Explanation / Answer
A) Critical position is just left to the gear
E) EN58,EN56 good material for bevel gear
E) EN56, low notch sensitive
