There is a need to design a spur gear transmission system to transmit a power of 3.7 kW from a shaft running at 1360 rpm with speed reduction of 4:1. Different standard modules of 20° full depth carefully cut gears are available with the following properties Allowable static Flexural endurance Surface endurance Material stress (o.) limit (o.) limit (oes) Cast iron 56 MPa 108 MPа 630 MPа Cast steel 140 MPа 350 MPa 490 MPа If the system have a heavy shock load working 10 hours per day in non- enclosed lubricated condition. Select a suitable module from suitable material for the gears from the state of dynamic and static action knowing that the cost of cast steel gear is twice the cast iron one and the tooth error in action (e) is 0.01 mm Determine the center distance and finally check the system for wear.
