A step down gear drive is used in a conveyor system. The input pinion is made of 18 teeth runs at 1720 rpm, the driven gear runs at 860 rpm. The gears are supported on less rigid mountings, less accurate gears. The gears are made by hobbing process. Find: (a) The tooth bending strength of both wheels and the maximum power that can be transmitted to the drive (b) By considering surface durability conditions find the_maximum power that can be...

The Isthmus Slough drawbridge has an open gear reduction for the span drive. A mating pair of gears pinion E and gear Fare located about mid-way in the 5 part speed reduction. The gear teeth are un- crowned open spur gears with a pressure angle o = 20 degrees. Both gears are made to an AGMA quality level Qv = 9 and have a measured hardness of HB = 183 made from through hardened Grade 1 Steel and are un-lapped....

output input 2. The gearbox in the diagram for problem 1 receives an input power of 10 kW, at a speed of 40. The gears are spur gears (ignore the helix angle on the teeth in the figure), have a module of 5 mm/tooth, and the pressure angle is 20. Assume all shafts lie in the same plane. Assume the gearbox is reasonably efficient, so losses can be neglected for this analysis. (a) Determine the minimum inside dimension of the...
