2 A pair of 20° involute gears are to be des driving a machine which is to run near as possible to 700rpm and required 40kW. The drive is from an electric motor which runs at 1200rpm. Both gears are to be manufactured from cast steel with a basic stress of 135MPa. The centre distance between the gears is approximately 230mm. Use the Lewis formula and calculate, assuming a module of 8: The number of teeth on each gear [21:36] The final centre distance [228mm] The actual speed of the machine [700rpm] A suitable face width [45mm] a) b) c)
