Design the shaft assembly of gear 2 with the following information:
Gear:
The specification of the involute helical gears are as follows
Pressure angle: 20 degrees
Torque acting on gear 1, T1= 95500Nmm
Number of teeth: N1= 55(gear1), N2=135(gear 2)
Helix angle= 15 degrees
Tooth Width b= 50 mm
Gear quality grade:8
Input speed n1=1450rpm
Machine for power input: electrical motor
Machines to be driven by the motor: push press drive
Tooth Surfaces of both gear 1 and 2 are soft
Material of both gears is steel
Allowable contact stress= 570N/mm2
Allowable bending stress= 380 N/mm2
Requirement:
Detail the following calculation/ selections
1) Gear Ebnding and contact stresses
2) Bearing selection
3)Key and key way design
I don't get how u can find out the module(m), I been trying to do it for days and I just can't work my way around it, please help me...my dealine is in 2 days time and I also need to produce a Auto CAd drawing too!
